     BACKGROUND 
     A network such as a local area network can comprise one or more network devices such as access points (AP) to provide a means for one or more user devices to communicate with and/or over the network. A network device can comprise a device that allows wired and/or wireless user devices to connect to a wired network using Wi-Fi, Bluetooth, or related technologies. A network device can be configured to provide access to one or more services (e.g., private network, public network, network-related services). In certain locations such as multi-dwelling units, where hundreds of network devices may be present, network devices can provide interfering wireless signals and excessive demand for access to the channel. These and other shortcomings are addressed by the present disclosure. 
     SUMMARY 
     In an aspect, methods can comprise determining signal information relating to a first network device such as an access point. The signal information may be associated with signal characteristics such as a radio frequency signal strength over a communication channel. An attenuation value for one or more receiving paths of the first network device may be determined using the signal information. The one or more receiving paths of the first network device may be attenuated based on the determined attenuation value. A transmission power of the first network device may be configured based on the determined attenuation value. 
     In another aspect, methods can comprise receiving signal information relating to one or more received signals on a communication channel associated with a first network device. As an example, at least a portion of the signal information is associated with a radio frequency signal strength over the communication channel. An attenuation value can be determined for one or more receiving paths of the first network device. The one or more receiving paths of the first network device can be attenuated based on the determined attenuation value. 
     In a further aspect, a network device can comprise one or more receiving paths configured to receive a plurality of radio frequency signals. An attenuator can be configured to attenuate one or more signals of the plurality of radio frequency signals based on at least a distribution of signal strengths of the plurality of radio frequency signals. A transmitter can be configured to transmit a radio frequency signal at a transmission power based on the attenuation effected by the attenuator. 
     Additional advantages will be set forth in part in the description which follows or may be learned by practice. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive.

     DETAILED DESCRIPTION 
     The methods and systems described herein, in one aspect, can allow a network device such as a wireless access point to access a network channel, while minimizing the impact of competing devices that share communication over the same network channel. As an example, the network device can attenuate one or more co-channel signals below a receiver noise floor, thus making a carrier sense mechanism of the network device immune to the presence of the competing co-channel signals. As another example, the network device can configure a transmitter power based on the attenuation applied to the received signals (e.g., dB-for-dB with the value of attenuation placed in the receive path(s)). This may ensure that the network device reciprocates with other network devices sharing the channel. As such, the network performance (e.g., downlink performance) of the network device can be improved by trading off an amount of downlink power at the receiver of the network device for significantly less channel congestion. In dense radio frequency (RF) environments, such as multi-story apartment buildings, where downlink signal strengths are strong to connected clients, this tradeoff offers significant opportunity for the network device to gain access to the channel for downlink transmissions. 
     In one aspect of the disclosure, a system can be configured to provide services such as network-related services.  FIG.  1    illustrates various aspects of an exemplary environment in which the present methods and systems can operate. The present disclosure is relevant to systems and methods for providing services to a user device, for example. Those skilled in the art will appreciate that present methods may be used in various types of networks and systems that employ both digital and analog equipment. One skilled in the art will appreciate that provided herein is a functional description and that the respective functions can be performed by software, hardware, or a combination of software and hardware. 
     The network and system can comprise a user device  102  in communication with a computing device  104 , such as a server, for example. The computing device  104  can be disposed locally or remotely relative to the user device  102 . As an example, the user device  102  and the computing device  104  can be in communication via a private and/or public network  105 , such as the Internet. Other forms of communications can be used, such as wired and wireless telecommunication channels, for example. 
     In an aspect, the user device  102  can be an electronic device, such as a computer, a smartphone, a laptop, a tablet, a set top box, a display device, or other device capable of communicating with the computing device  104 . As an example, the user device  102  can comprise a communication element  106  for providing an interface to a user to interact with the user device  102  and/or the computing device  104 . The communication element  106  can be any interface for presenting information to the user and receiving a user feedback, such as a application client or a web browser (e.g., Internet Explorer, Mozilla Firefox, Google Chrome, Safari, or the like). Other software, hardware, and/or interfaces can be used to provide communication between the user and one or more of the user device  102  and the computing device  104 . As an example, the communication element  106  can request or query various files from a local source and/or a remote source. As a further example, the communication element  106  can transmit data to a local or remote device, such as the computing device  104 . 
     In an aspect, the user device  102  can be associated with a user identifier or device identifier  108 . As an example, the device identifier  108  can be any identifier, token, character, string, or the like, for differentiating one user or user device (e.g., user device  102 ) from another user or user device. In a further aspect, the device identifier  108  can identify a user or user device as belonging to a particular class of users or user devices. As a further example, the device identifier  108  can comprise information relating to the user device, such as a manufacturer, a model or type of device, a service provider associated with the user device  102 , a state of the user device  102 , a locator, and/or a label or classifier. Other information can be represented by the device identifier  108 . 
     In an aspect, the device identifier  108  can comprise an address element  110  and a service element  112 . In an aspect, the address element  110  can be an internet protocol address, a MAC address, a network address, an Internet address, or the like. As an example, the address element  110  can be relied upon to establish a communication session between the user device  102  and the computing device  104  or other devices and/or networks. As a further example, the address element  110  can be used as an identifier or locator of the user device  102 . In an aspect, the address element  110  can be persistent for a particular network and/or location. 
     In an aspect, the service element  112  can comprise an identification of a service provider associated with the user device  102  and/or with the class of user device  102 . As an example, the service element  112  can comprise information relating to or provided by a communication service provider (e.g., Internet service provider) that is providing or enabling communication services to the user device  102 . As a further example, the service element  112  can comprise information relating to a preferred service provider for one or more particular services relating to the user device  102 . In an aspect, the address element  110  can be used to identify or retrieve the service element  112 , or vise versa. As a further example, one or more of the address element  110  and the service element  112  can be stored remotely from the user device  102  and retrieved by one or more devices, such as the user device  102  and the computing device  104 . Other information can be represented by the service element  112 . 
     In an aspect, the computing device  104  can be a server for communicating with the user device  102 . As an example, the computing device  104  can communicate with the user device  102  for providing services. In an aspect, the computing device  104  can allow the user device  102  to interact with remote resources, such as data, devices, and files. As an example, the computing device can be configured as central location (e.g., a headend, or processing facility), which can receive content (e.g., data, input programming) from multiple sources. The computing device  104  can combine the content from the various sources and can distribute the content to user (e.g., subscriber) locations via a distribution system. 
     In an aspect, the computing device  104  can manage the communication between the user device  102  and a database  114  for sending and receiving data therebetween. As an example, the database  114  can store a plurality of data sets (e.g., mapped identifiers, relational tables, user device identifiers (e.g., identifier  108 ) or records, network device identifiers (e.g., identifier  118 ), or other information). As a further example, the user device  102  can request and/or retrieve a file from the database  114 . In an aspect, the database  114  can store information relating to the user device  102 , such as the address element  110  and/or the service element  112 . As an example, the computing device  104  can obtain the device identifier  108  from the user device  102  and retrieve information from the database  114 , such as the address element  110  and/or the service elements  112 . As another example, the computing device  104  can obtain the address element  110  from the user device  102  and can retrieve the service element  112  from the database  114 , or vice versa. As a further example, the computing device  104  can obtain a MAC address from the user device  102  and can retrieve a local IP address from the database  114 . As such, the local IP address can be provisioned to the user device  102 , for example, as the address element  110  to facilitate interaction between the user device  102  and a network (e.g., LAN). Any information can be stored in and retrieved from the database  114 . The database  114  can be disposed remotely from the computing device  104  and accessed via direct or indirect connection. The database  114  can be integrated with the computing device  104  or some other device or system. 
     In an aspect, one or more network devices  116  can be in communication with a network, such as network  105 . As an example, one or more of the network devices  116  can facilitate the connection of a device, such as user device  102 , to the network  105 . As a further example, one or more of the network devices  116  can be configured as a network gateway. In an aspect, one or more network devices  116  can be configured to allow one or more wireless devices to connect to a wired and/or wireless network using Wi-Fi, Bluetooth or similar standard. 
     In an aspect, the network devices  116  can be configured to transmit and receive wireless signals (e.g., RF signals) over a particular frequency band. Such bands can include 2.4 GHz band, 5 Ghz band, and 60 GHz band among others. The frequency band can be defined by one or more communication protocols or standards such as 802.xx (e.g., 802.11ac, n, a, b, g, etc.). Each of the frequency bands can be sub-divided into one or more communication channels. As an example, the 2.4 GHz band can comprise frequencies between 2400 MHz and 2500 MHz and can be divided into 14 sub channels (e.g., 20 MHz sub-band channels). As such, each of the network devices  116  can be configured to transmit and receive wireless signals over a select one or more of the channels of a particular frequency band. 
     In an aspect, the network devices  116  can be configured as a mesh network. As an example, one or more network devices  116  can comprise a dual band wireless network device. As an example, the network devices  116  can be configured with a first service set identifier (SSID) (e.g., associated with a user network or private network) to function as a local network for a particular user or users. As a further example, the network devices  116  can be configured with a second service set identifier (SSID) (e.g., associated with a public/community network or a hidden network) to function as a secondary network or redundant network for connected communication devices. 
     In an aspect, one or more network devices  116  can comprise an identifier  118 . As an example, one or more identifiers can be a media access control address (MAC address). As a further example, one or more identifiers  118  can be a unique identifier for facilitating communications on the physical network segment. In an aspect, each of the network devices  116  can comprise a distinct identifier  118 . As an example, the identifiers  118  can be associated with a physical location of the network devices  116 . 
     In an aspect, the user device  102  can connect to a first network, such as a LAN associated with a first SSID, via a network device (e.g., network device  116 , gateway device, computing device  104 , server, router, etc.) As an example, the user device  102  can discover a beacon  120  transmitted (e.g., wirelessly) by the network device  116 . The beacon  120  can comprise a beacon frame. The beacon  120  can comprise information to facilitate a connection between the user device  102  and the network device  116 . As a further example, a second beacon  120 ′ can be transmitted by another network device  116  over the same or different communication channel as the beacon  120 . 
     In an aspect, as more user devices  102  discover the beacons  120 ,  120 ′ and communicate over the same channel, the co-signals being transmitted over the same channel can cause congestion and poor network performance for one or more of the user devices  102 . The methods and systems described herein can use an RF scan to determine a number of signal transmissions (e.g., service set identifiers (SSID)) that are being transmitted via one or more communication channels. The RF scan can also determine a received signal strength indicator (RSSI) associated with one or more of the SSIDs. As an example, a distribution of RSSI (signal strength) can be determined for one or more of the network devices  116 . As another example, a distribution of RSSI (signal strength) can be determined from one or more user devices  102  (e.g., clients) that have connected to the one or more network devices  116  (e.g., via storage of a history of connected client&#39;s uplink RSSI). Upon activation, many network devices  116  may scan all possible channels to determine an optimal operating channel as part of an auto-channel-select feature. Data from this scan may form a distribution of RSSI values. The RSSI distribution can be updated through the ongoing RSSI measurement of on-channel beacons  120 . Thus, the RF environment of the network device  116  can be discovered. Inasmuch as network devices  116  are generally stationary, the measured RSSI values may have a small variation and can be sampled and refreshed periodically. From this data set, a distribution of RSSI values from other network devices  116  may be stored. 
     Based on one or more of the determined distributions of RSSI, the one or more network devices  116  can attenuate one or more co-channel signals by a value to make the carrier sense mechanism of the one or more network devices  116  immune to the presence of the competing co-channel signals. Various strategies can be employed to determine the optimal amount of attenuation. One strategy is to determine the attenuation to exclude the bottom “x-percentile” of neighboring network devices  116 , where “x” is a configurable parameter. In high-density environments, a large number of network devices may be received near the noise floor (e.g., −90 dB) of the network device  116 . Another strategy is to exclude the network devices within “x-dB” of the noise floor, where “x” is a configurable parameter. 
     In certain aspects, the one or more network devices  116  can configure a transmitter power based on the attenuation applied to the received signals (e.g., dB-for-dB with the value of attenuation placed in the receive path(s)). This may ensure that the network devices  116  reciprocate with other network devices  116  sharing the channel. As such, the network performance (e.g., downlink performance) of the network devices  116  can be improved by trading off an amount of downlink power at the receiver of the network device for less channel congestion. As another example, the receiving paths of the network devices  116  can be attenuated via one or more programmable electronic attenuators (e.g., stepped, updated, self-adapting, etc.), one or more PIN diodes (e.g., diode switched attenuator), and may be controlled locally or via upstream intelligence. As a further example, the network devices  116  can have a configurable limit imposed by a vendor or network operator to limit the extent of adjustment to receiver sensitivity and transmit power, or incremental amounts of compensation that can be imposed by the user or network operator to improve performance where channel activity exceeds a threshold. 
     In an exemplary aspect, the methods and systems can be implemented on a computing system, such as computing device  200  as illustrated in  FIG.  2    and described below. By way of example, one or more of the user device  102  and the computing device  104  of  FIG.  1    can be embodied as the computing device  200  as illustrated in  FIG.  2   . Similarly, the methods and systems disclosed can utilize one or more computers to perform one or more functions in one or more locations.  FIG.  2    depicts a general-purpose computer system that includes or is configured to access one or more computer-accessible media. In the illustrated aspect, a computing device  200  may include one or more processors  210   a ,  210   b , and/or  210   n  (which may be referred herein singularly as the processor  210  or in the plural as the processors  210 ) coupled to a system memory  220  via an input/output (I/O) interface  230 . The computing device  200  may further include a network interface  240  coupled to an I/O interface  230 . 
     In various aspects, the computing device  200  may be a uniprocessor system including one processor  210  or a multiprocessor system including several processors  210  (e.g., two, four, eight, or another suitable number). The processors  210  may be any suitable processors capable of executing instructions. For example, in various aspects, the processor(s)  210  may be general-purpose or embedded processors implementing any of a variety of instruction set architectures (ISAs), such as the x86, PowerPC, SPARC, or MIPS ISAs, or any other suitable ISA. In multiprocessor systems, each of the processors  210  may commonly, but not necessarily, implement the same ISA. 
     In some aspects, a graphics processing unit (“GPU”)  212  may participate in providing graphics rendering and/or physics processing capabilities. A GPU may, for example, include a highly parallelized processor architecture specialized for graphical computations. In some aspects, the processors  210  and the GPU  212  may be implemented as one or more of the same type of device. 
     The system memory  220  may be configured to store instructions and data accessible by the processor(s)  210 . In various aspects, the system memory  220  may be implemented using any suitable memory technology, such as static random access memory (“SRAM”), synchronous dynamic RAM (“SDRAM”), nonvolatile/Flash®-type memory, or any other type of memory. In the illustrated aspect, program instructions and data implementing one or more desired functions, such as those methods, techniques and data described above, are shown stored within the system memory  220  as code  225  and data  226 . 
     In one aspect, the I/O interface  230  may be configured to coordinate I/O traffic between the processor(s)  210 , the system memory  220  and any peripherals in the device, including a network interface  240  or other peripheral interfaces. In some aspects, the I/O interface  230  may perform any necessary protocol, timing or other data transformations to convert data signals from one component (e.g., the system memory  220 ) into a format suitable for use by another component (e.g., the processor  210 ). In some aspects, the I/O interface  230  may include support for devices attached through various types of peripheral buses, such as a variant of the Peripheral Component Interconnect (PCI) bus standard or the Universal Serial Bus (USB) standard, for example. In some aspects, the function of the I/O interface  230  may be split into two or more separate components, such as a north bridge and a south bridge, for example. Also, in some aspects some or all of the functionality of the I/O interface  230 , such as an interface to the system memory  220 , may be incorporated directly into the processor  210 . 
     The network interface  240  may be configured to allow data to be exchanged between the computing device  200  and other device or devices  260  attached to a network or networks  250 , such as other computer systems or devices, for example. In various aspects, the network interface  240  may support communication via any suitable wired or wireless general data networks, such as types of Ethernet networks, for example. Additionally, the network interface  240  may support communication via telecommunications/telephony networks, such as analog voice networks or digital fiber communications networks, via storage area networks, such as Fibre Channel SANs (storage area networks), or via any other suitable type of network and/or protocol. 
     In some aspects, the system memory  220  may be one aspect of a computer-accessible medium configured to store program instructions and data as described above for implementing aspects of the corresponding methods and apparatus. However, in other aspects, program instructions and/or data may be received, sent, or stored upon different types of computer-accessible media. Generally speaking, a computer-accessible medium may include non-transitory storage media or memory media, such as magnetic or optical media, e.g., disk or DVD/CD coupled to computing device the  200  via the I/O interface  230 . A non-transitory computer-accessible storage medium may also include any volatile or non-volatile media, such as RAM (e.g., SDRAM, DDR SDRAM, RDRAM, SRAM, etc.), ROM, etc., that may be included in some aspects of the computing device  200  as the system memory  220  or another type of memory. Further, a computer-accessible medium may include transmission media or signals, such as electrical, electromagnetic or digital signals, conveyed via a communication medium, such as a network and/or a wireless link, such as those that may be implemented via the network interface  240 . Portions or all of multiple computing devices, such as those illustrated in  FIG.  2   , may be used to implement the described functionality in various aspects; for example, software components running on a variety of different devices and servers may collaborate to provide the functionality. In some aspects, portions of the described functionality may be implemented using storage devices, network devices or special-purpose computer systems, in addition to or instead of being implemented using general-purpose computer systems. The term “computing device,” as used herein, refers to at least all these types of devices and is not limited to these types of devices.

Such attributes can comprise one or more of an IP Address, serial number, latitude/longitude, geo-encoding, custom assigned unique identifier, global unique identifier (GUID), and the like. As a further example, one or more identifiers  308   a ,  308   b ,  308   c ,  308   d  can be a unique identifier for facilitating communications on the physical network segment. In an aspect, each of the nodes  302   a ,  302   b ,  302   c ,  302   d  can comprise a distinct identifier  308   a ,  308   b ,  308   c ,  308   d . As an example, the identifiers  308   a ,  308   b ,  308   c ,  308   d  can be associated with a physical location of the nodes  302   a ,  302   b ,  302   c ,  302   d.    
     In an aspect, one or more nodes  302   a ,  302   b ,  302   c ,  302   d  can be in communication with the gateway  304 . As an example, one or more nodes  302   a ,  302   b ,  302   c ,  302   d  and/or the gateway  304  can be configured to allow one or more wireless devices to connect to a wired and/or wireless network using Wi-Fi, Bluetooth or similar standard. The gateway  304  can comprise an identifier  309 . As an example, one or more identifiers  309  can be a media access control address (MAC address). As a further example, one or more identifiers  309  can be a unique identifier for facilitating communications on the physical network segment. 
     In an aspect, a computing device  310  can be in communication with a network device, such as gateway  304 . As an example, the computing device  310  can be or comprise an application server, management device, auto-configuration server (ACS), AAA server, etc. In another aspect, the computing device  310  is located within a network, such as a wide area network (WAN). 
     In an aspect, the user devices  303   a ,  303   b  can connect to a first network via a network device, such as node  302   b . As an example, the user device  303   a ,  303   b  can discover a transmission signal  312  (e.g., downlink, beacon, etc.) transmitted (e.g., wirelessly) by the node  302   b . The transmission signal  312  can be transmitted over a particular frequency band. Such bands can include 2.4 GHz band, 5 Ghz band, and 60 GHz band among others. The frequency band can be defined by one or more communication protocols or standards such as 802.xx or similar standards. Each of the frequency bands can be sub-divided into one or more communication channels. As an example, the 2.4 GHz band can comprise frequencies between 2400 MHz and 2500 MHz and can be divided into 14 sub channels (e.g., 20 MHz sub-band channels). As such, the gateway  304  and/or one or more nodes  302   a ,  302   b ,  302   c ,  302   d  can be configured to transmit and receive wireless signals over a select one or more of the channels of a particular frequency band. As an example, a first signal  307   a  can be received by the node  302   b  from the user device  303   a  and a second signal  307   b  can be received by the node  302   b  from the user device  303   b . In certain aspects, the first signal  307   a  and the second signal  307   b  can be received over the same communication channel (e.g., frequency band and/or sub-band). Other signals and interference from nodes  302   a ,  302   c ,  302   d  and other devices in the area may be received and/or may contribute to noise of the signals  307   a ,  307   b.    
     In an aspect, as more user devices  303   a ,  303   b  and/or nodes  302   a ,  302   b ,  302   c ,  302   d  communicate over the same channel, the co-signals being transmitted over the same channel can cause congestion and poor network performance for one or more of the user devices  303   a ,  303   b  and the nodes  302   a ,  302   b ,  302   c ,  302   d . As an example, the node  302   b  can attenuate one or more co-channel signals  307   a ,  307   b  below a receiver noise floor, thus making a carrier sense mechanism of the node  302   b  immune to the presence of the competing co-channel signals. Such attenuation can be effected by a control device local to the node  302   b  or in response to a signal received from a remote processor configured to determine the appropriate attenuation value. As another example, the node  302   b  can configure a transmitter power of the transmission signal  312  based on the attenuation level of the received signals (e.g., dB-for-dB with the value of attenuation placed in the receive path(s)). As a further example, any number of the nodes  302   a ,  302   b ,  302   c ,  302   d  can be configured to attenuate a receiver channel and may adjust transmission to minimize the signal noise over particular channels. 
     Referring now to  FIG.  4   , the signals  307   a ,  307   b  can be attenuated to remove at least one of the signals  307   a ,  307   b  from processing by the node  302   b . For example, if the receiving paths of the node  302   b  are attenuated by a predetermined level (e.g., −20 dB), for example, based on a distribution of RSSI between one or more user devices  303  and nodes  302 , some of the lower powered signals may be attenuated below a preset noise floor (e.g., −90 dBm) of the node  302   b . As such, the network performance (e.g., downlink performance) of the node  302   b  can be improved by trading off an amount of downlink power at the receiver of the node  302   b  device for significantly less channel congestion. In dense radio frequency (RF) environments, such as multi-story apartment buildings, where downlink signal strengths are strong to connected user devices  303 , this tradeoff offers an opportunity for the network device to gain access to the channel for downlink transmissions. 
     This technique can be used to attenuate any signals that may be received via a receiving path of the node  302   b  or that may contribute to noise on a receiving path of the node  302   b  is tuned. As an example, a signal-to-noise ratio on a particular channel may be minimized by pushing lower powered signals below a noise floor of a recipient device (e.g., node  302   b  in the above example). As such, the transmission of other nodes  302   b ,  302   c ,  302   d  and the other user devices  303  may be effectively eliminated from being processed by the node  302   b , thereby dedicating the localized communication channel to the more powerful signals, for example, signals between the node  302   b  and the user device  303   a . Each node  302   a ,  302   b ,  302   c ,  302   d  can be configured based on wireless signals within reception of the respective node  302   a ,  302   b ,  302   c ,  302   d  and may be configured individually or as a group. 
     An exemplary method is shown in  FIG.  5   . In step  502 , signal information can be determined, for example, via one or more of a user device (e.g., user device  102  ( FIG.  1   )) and a computing device (e.g., computing device  104 , network device  116  ( FIG.  1   )) such as a network computing device. The signal information can be determined via a signal scan such as an RF scan of network signals being transmitted in a given area. As an example, the user device and/or the computing device may be configured with a logical tool (e.g., RF scan) that can receive one or more transmitted wireless signals and can extract the signal information for each of the one or more transmitted wireless signals. As a further example, a remote device can be configured with the logical tool and can transmit information relating to the one or more received wireless signals to the network computing device for processing the signal information. 
     The signal information can relate to a first network device such as a wireless access point (e.g., network device  116  ( FIG.  1   )). At least a portion of the signal information can be associated with a first network. In an aspect, the signal information can relate to signal strength, signal identifiers, noise, or a combination thereof. The methods and systems described herein can use an RF scan to determine a number of signal transmissions (e.g., service set identifiers (SSID)) that are being transmitted via one or more communication channels. The RF scan can also determine a received signal strength indicator (RSSI) associated with one or more of the SSIDs. As an example, a distribution of RSSI (signal strength) can be determined for one or more of the network devices  116  ( FIG.  1   ). 
     In step  504 , an attenuation value can be determined for one or more receiving paths of the first network device (e.g., network device  116  ( FIG.  1   )). The attenuation value can be determined via one or more of a user device (e.g., user device  102  ( FIG.  1   )), a computing device (e.g., computing device  104  ( FIG.  1   ), and/or the first network device. In an aspect, the attenuation value can be determined based at least on the determined signal information. Various strategies can be used to determine the attenuation value such as discrete dB steps, configurable by the device vendor or network operator. For example, based on the signal information determined in step  502 , a particular device (e.g., user device and/or first network device) may be capable of receiving four distinct wireless signals, having a signal strength of −60 dB, −70 dB, −85 dB, and −89 dB respectively. A noise floor for the first network device may be established at −90 dB and signals with a strength of less than −90 dB may be ignored by the first network device. Accordingly, an attenuation value step of −3 dB can be implemented to remove certain wireless signals from processing by the first network device. 
     Another strategy for determining the attenuation value can include calculating the attenuation value as a function of a statistical distribution of received wireless signals. As such, the attenuation value can be configured to exclude the bottom “x-percentile” of received signals (e.g., readable SSIDs) from being received by one or more devices, such as user device. As an example, a user device may discover ten wireless signals, each associated with a distinct SSID and having a signal strength of −50 dB, −55 dB, −60 dB, −65 db, −70 db, −80 dB, −81 dB, −82 dB, −83 dB, and −84 dB, respectively. An exclusion rule can be used to filter the lowest fifty percent of receivable wireless signals. Applying such a rule to the example signal strength requires an attenuation value of −10 dB to push the bottom fifty percent of the received signals below the noise floor of −90 dB. Accordingly, the attenuation value can be determined to be −10 dB. As a further example, the first network device may determine the signal strength of a received signal associated with particular SSIDs and can determine the attenuation value based on the distribution of the received signals. 
     Another strategy for determining the attenuation value can include a configurable value based on historical and/or real-time data collected in various environments. For example, a single family home environment may have a different attenuation value strategy than a multi-unit dwelling with hundreds of apartments in close proximity to each other. As such, the attenuation value can be determined based on the environment of the first network device. 
     In step  506 , the one or more receiving paths of the first network device can be attenuated. Such attenuation can be based on the determined attenuation value. As another example, the receiving paths of the first network device can be attenuated via one or more programmable electronic attenuators (e.g., stepped, updated, self-adapting, etc.), one or more PIN diodes (e.g., diode switched attenuator), and may be controlled locally or via upstream intelligence. As a further example, the first network device can have a configurable limit imposed by a vendor or network operator to limit the extent of adjustment to receiver sensitivity and transmit power, or incremental amounts of compensation that can be imposed by the user or network operator to improve performance where channel activity exceeds a threshold. 
     As an illustrative example, the first network device may be capable of receiving four distinct wireless signals, having a signal strength of −60 dB, −70 dB, −85 dB, and −89 dB respectively. By applying a first attenuation step of −3 dB to one or more receiving paths of the first network device, the received signal strengths become −63 dB, −73 dB, −88 dB, and −92 dB, respectively. The signals have signal strength of −63 dB and −73 dB may be minimal affected, while the signal having a signal strength of −92 dB may fall below the noise floor and may be ignored by the first network device. Applying a second attenuation step of −3 dB may further eliminate another signal by pushing the signal strength to −91 dB, below the noise threshold. 
     In step  508 , a transmission power of the first network device can be configured. In an aspect, the transmission power can be configured based on the determined attenuation value, such as a dB-to-dB adjustment with the determined attenuation value. As an example, if the receive paths of the first network device are attenuated by −3 dB, the transmission power of one or more radio signals of the first network device may be attenuated by −3 dB. In step  510 , access to a first network can be provided to one or more devices via the first network device. 
     An exemplary method is shown in  FIG.  6   . In step  602 , signal information can be accessed or received, for example retrieved from storage or accessed via one or more of a user device (e.g., user device  102  ( FIG.  1   )) and a computing device (e.g., computing device  104 , network device  116  ( FIG.  1   )) such as a network computing device. The signal information can relate to a first network device such as a wireless access point (e.g., network device  116  ( FIG.  1   )). At least a portion of the signal information can be associated with a first network. In an aspect, the signal information can relate to signal strength, signal identifiers, noise, or a combination thereof. The methods and systems described herein can use an RF scan to determine a number of signal transmissions (e.g., service set identifiers (SSID)) that are being transmitted via one or more communication channels. The RF scan can also determine a received signal strength indicator (RSSI) associated with one or more of the SSIDs. As an example, a distribution of RSSI (signal strength) can be determined for one or more of the network devices  116  ( FIG.  1   ). 
     In step  604 , an attenuation value can be determined for one or more receiving paths of the first network device (e.g., network device  116  ( FIG.  1   )). The attenuation value can be determined via one or more of a user device (e.g., user device  102  ( FIG.  1   )), a computing device (e.g., computing device  104  ( FIG.  1   ), and/or the first network device. In an aspect, the attenuation value can be determined based at least on the determined signal information. Various strategies can be used to determine the attenuation value such as discrete dB steps, configurable by the device vendor or network operator. Another strategy for determining the attenuation value can include calculating the attenuation value as a function of a statistical distribution of received wireless signals. As such, the attenuation value can be configured to exclude the bottom “x-percentile” of received signals (e.g., readable SSIDs) from being received by one or more devices, such as user device. 
     In step  606 , the one or more receiving paths of the first network device can be attenuated. Such attenuation can be based on the determined attenuation value. As another example, the receiving paths of the first network device can be attenuated via one or more programmable electronic attenuators (e.g., stepped, updated, self-adapting, etc.), one or more PIN diodes (e.g., diode switched attenuator), and may be controlled locally or via upstream intelligence. As a further example, the first network device can have a configurable limit imposed by a vendor or network operator to limit the extent of adjustment to receiver sensitivity and transmit power, or incremental amounts of compensation that can be imposed by the user or network operator to improve performance where channel activity exceeds a threshold. In step  608 , access to a first network can be provided to one or more device via the first network device.
