In various embodiments, macro network platform  1010  includes CS gateway (GW) node(s)  1012  that can interface CS traffic received from legacy networks like telephony network(s)  1040 , e.g., public switched telephone network (PSTN), public land mobile network (PLMN), Signaling System No. 7 (SS7) network  1060 , etc. CS GW node(s)  1012  can authorize and authenticate traffic, e.g., voice, arising from such networks. Additionally, CS GW node(s)  1012  can access mobility or roaming data generated through SS7 network  1060 ; for instance, mobility data stored in a visitor location register (VLR), which can reside in memory  1030 . Moreover, CS GW node(s)  1012  interfaces CS-based traffic and signaling with PS GW node(s)  1018 . As an example, in a 3GPP UMTS network, PS GW node(s)  1018  can be embodied in GW general packet radio service (GPRS) support node(s) (GGSN). 
     As illustrated by  FIG.  10   , PS GW node(s)  1018  can receive and process CS-switched traffic and signaling via CS GW node(s)  1012 . Further PS GW node(s)  1018  can authorize and authenticate PS-based data sessions, e.g., via the cellular system, with served devices, communication devices, etc. Such data sessions can include traffic exchange with networks external to macro network platform  1010 , like wide area network(s) (WANs)  1050 ; enterprise networks (NWs)  1070 , e.g., E911, service NW(s)  1080 , e.g., an IP multimedia subsystem (IMS), etc. It should be appreciated that local area network(s) (LANs), which may be a part of enterprise NW(s)  1070 , can also be interfaced with macro network platform  1010  through PS GW node(s)  1018 . PS GW node(s)  1018  can generate packet data contexts when a data session is established, e.g., associated with an EPS bearer context activation. To that end, in an aspect, PS GW node(s)  1018  can include a tunnel interface, e.g., tunnel termination GW (TTG) in 3GPP UMTS network(s) (not shown), which can facilitate packetized communication with disparate wireless network(s), such as Wi-Fi networks. It should be further appreciated that the packetized communication can include multiple flows that can be generated through server(s)  1014 . It is to be noted that in 3GPP UMTS network(s), PS GW node(s)  1018  (e.g., GGSN) and tunnel interface (e.g., TTG) comprise a packet data GW (PDG). 
     Macro network platform  1010  also includes serving node(s)  1016  that can convey the various packetized flows of information, or data streams, received through PS GW node(s)  1018 . As an example, in a 3GPP UMTS network, serving node(s) can be embodied in serving GPRS support node(s) (SGSN). 
     As indicated above, server(s)  1014  in macro network platform  1010  can execute numerous applications, e.g., messaging, location services, wireless device management, etc. that can generate multiple disparate packetized data streams or flows; and can manage such flows, e.g., schedule, queue, format. Such application(s), for example can include add-on features to standard services provided by macro network platform  1010 . Data streams can be conveyed to PS GW node(s)  1018  for authorization/authentication and initiation of a data session, and to serving node(s)  1016  for communication thereafter. Server(s)  1014  can also effect security, e.g., implement one or more firewalls, of macro network platform  1010  to ensure network&#39;s operation and data integrity in addition to authorization and authentication procedures that CS GW node(s)  1012  and PS GW node(s)  1018  can enact. Moreover, server(s)  1014  can provision services from external network(s), e.g., WAN  1050 , or global positioning system (GPS) network(s), which can be a part of enterprise NW(s)  1080 . It is to be noted that server(s)  1014  can include one or more processors configured to confer at least in part the functionality of macro network platform  1010 . To that end, the one or more processors can execute code instructions stored in memory  1030 , for example. 
     In wireless communication environment  1000 , memory  1030  can store information related to operation of macro network platform  1010 , e.g., related to operation of a base station device (e.g.,  101 ), etc. The information can include data, business data, etc. associated with subscribers of respective services; market plans and strategies, e.g., promotional campaigns, business partnerships, mobile devices served through macro network platform, etc.; service and privacy information, policies, etc.; end-user service logs for law enforcement; term(s) and/or condition(s) associated with wireless service(s) provided via the cellular system; and so forth. Memory  1030  can also store information from at least one of telephony network(s)  1040 , WAN  1050 , SS7 network  1060 , enterprise NW(s)  1070 , or service NW(s)  1080 . 
     In one or more embodiments, components of wireless communication environment  1000  can provide communication services to the device utilizing an over-the-air wireless link (e.g.,  1020 ) via the cellular system. In this regard, the cellular system can include one or more: macro, Femto, or pico access points (APs) (not shown); base stations (BS) ( 101 ); landline networks (e.g., optical landline networks, electrical landline networks) (not shown) communicatively coupled between the device and macro network platform  1010 , etc. 
     Wireless communication environment  1000  can include one or more of the Internet (or another communication network (e.g., IP-based network)), or DSL-type or broadband network facilitated by Ethernet or other technology. In various embodiments, wireless communication environment  1000  can include hardware and/or software for allocating resources to the device and the cellular system, converting or enforcing protocols, establishing and/or providing levels of quality of service (QoS), providing applications or services, translating signals, and/or performing other desired functions to facilitate system interoperability and communication to/from the device and the cellular system. 
     In other embodiment(s), wireless communication environment  1000  can include data store component(s), a memory configured to store information, computer-readable storage media storing computer-executable instructions, e.g., memory component  440 , memory  1030 , etc. enabling various operations performed via wireless system as described herein.

Additionally, the disclosed memory components of systems or methods herein are intended to comprise, without being limited to comprising, these and any other suitable types of memory. 
     In order to provide additional context for various embodiments described herein,  FIG.  11    and the following discussion are intended to provide a brief, general description of a suitable computing environment  1100  in which the various embodiments of the embodiment described herein can be implemented. While the embodiments have been described above in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the embodiments can be also implemented in combination with other program modules and/or as a combination of hardware and software. 
     Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that in various embodiments, methods disclosed herein can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, Internet of Things (IoT) devices, distributed computing systems, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices. 
     The illustrated embodiments of the embodiments herein can be also practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices. 
     Computing devices typically include a variety of media, which can include computer-readable storage media, machine-readable storage media, and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable storage media or machine-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media or machine-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable or machine-readable instructions, program modules, structured data or unstructured data. 
     Computer-readable storage media can include, but are not limited to, random access memory (RAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM), flash memory or other memory technology, compact disk read only memory (CD-ROM), digital versatile disk (DVD), Blu-ray disc (BD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, solid state drives or other solid state storage devices, or other tangible and/or non-transitory media which can be used to store desired information. In this regard, the terms “tangible” or “non-transitory” herein as applied to storage, memory or computer-readable media, are to be understood to exclude only propagating transitory signals per se as modifiers and do not relinquish rights to all standard storage, memory or computer-readable media that are not only propagating transitory signals per se. 
     Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium. 
     Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. 
     With reference again to  FIG.  11   , the example environment  1100  for implementing various embodiments of the aspects described herein includes a computer  1102 , the computer  1102  including a processing unit  1104 , a system memory  1106  and a system bus  1108 . The system bus  1108  couples system components including, but not limited to, the system memory  1106  to the processing unit  1104 . The processing unit  1104  can be any of various commercially available processors. Dual microprocessors and other multi-processor architectures can also be employed as the processing unit  1104 . 
     The system bus  1108  can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory  1106  includes ROM  1110  and RAM  1112 . A basic input/output system (BIOS) can be stored in a non-volatile memory such as ROM, erasable programmable read only memory (EPROM), EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer  1102 , such as during startup. The RAM  1112  can also include a high-speed RAM such as static RAM for caching data. 
     The computer  1102  further includes an internal hard disk drive (HDD)  1114  (e.g., EIDE, SATA), one or more external storage devices  1116  (e.g., a magnetic floppy disk drive (FDD)  1116 , a memory stick or flash drive reader, a memory card reader, etc.) and an optical disk drive  1120  (e.g., which can read or write from a CD-ROM disc, a DVD, a BD, etc.). While the internal HDD  1114  is illustrated as located within the computer  1102 , the internal HDD  1114  can also be configured for external use in a suitable chassis (not shown). Additionally, while not shown in environment  1100 , a solid-state drive (SSD) could be used in addition to, or in place of, an HDD  1114 . The HDD  1114 , external storage device(s)  1116  and optical disk drive  1120  can be connected to the system bus  1108  by an HDD interface  1124 , an external storage interface  1126  and an optical drive interface  1128 , respectively. The interface  1124  for external drive implementations can include at least one or both of Universal Serial Bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 interface technologies. Other external drive connection technologies are within contemplation of the embodiments described herein. 
     The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer  1102 , the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to respective types of storage devices, it should be appreciated by those skilled in the art that other types of storage media which are readable by a computer, whether presently existing or developed in the future, could also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods described herein. 
     A number of program modules can be stored in the drives and RAM  1112 , including an operating system  1130 , one or more application programs  1132 , other program modules  1134  and program data  1136 . All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM  1112 . The systems and methods described herein can be implemented utilizing various commercially available operating systems or combinations of operating systems. 
     Computer  1102  can optionally comprise emulation technologies. For example, a hypervisor (not shown) or other intermediary can emulate a hardware environment for operating system  1130 , and the emulated hardware can optionally be different from the hardware illustrated in  FIG.  11   . In such an embodiment, operating system  1130  can comprise one virtual machine (VM) of multiple VMs hosted at computer  1102 . Furthermore, operating system  1130  can provide runtime environments, such as the Java runtime environment or the .NET framework, for applications  1132 . Runtime environments are consistent execution environments that allow applications  1132  to run on any operating system that includes the runtime environment. Similarly, operating system  1130  can support containers, and applications  1132  can be in the form of containers, which are lightweight, standalone, executable packages of software that include, e.g., code, runtime, system tools, system libraries and settings for an application. 
     Further, computer  1102  can be enabled with a security module, such as a trusted processing module (TPM). For instance with a TPM, boot components hash next in time boot components, and wait for a match of results to secured values, before loading a next boot component. This process can take place at any layer in the code execution stack of computer  1102 , e.g., applied at the application execution level or at the operating system (OS) kernel level, thereby enabling security at any level of code execution. 
     A user can enter commands and information into the computer  1102  through one or more wired/wireless input devices, e.g., a keyboard  1138 , a touch screen  1140 , and a pointing device, such as a mouse  1142 . Other input devices (not shown) can include a microphone, an infrared (IR) remote control, a radio frequency (RF) remote control, or other remote control, a joystick, a virtual reality controller and/or virtual reality headset, a game pad, a stylus pen, an image input device, e.g., camera(s), a gesture sensor input device, a vision movement sensor input device, an emotion or facial detection device, a biometric input device, e.g., fingerprint or iris scanner, or the like. These and other input devices are often connected to the processing unit  1104  through an input device interface  1144  that can be coupled to the system bus  1108 , but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a USB port, an IR interface, a BLUETOOTH® interface, etc. 
     A monitor  1146  or other type of display device can be also connected to the system bus  1108  via an interface, such as a video adapter  1148 . In addition to the monitor  1146 , a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc. 
     The computer  1102  can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s)  1150 . The remote computer(s)  1150  can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer  1102 , although, for purposes of brevity, only a memory/storage device  1152  is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN)  1154  and/or larger networks, e.g., a wide area network (WAN)  1156 . Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet. 
     When used in a LAN networking environment, the computer  1102  can be connected to the local network  1154  through a wired and/or wireless communication network interface or adapter  1158 . The adapter  1158  can facilitate wired or wireless communication to the LAN  1154 , which can also include a wireless access point (AP) disposed thereon for communicating with the adapter  1158  in a wireless mode. 
     When used in a WAN networking environment, the computer  1102  can include a modem  1160  or can be connected to a communications server on the WAN  1156  via other means for establishing communications over the WAN  1156 , such as by way of the Internet. The modem  1160 , which can be internal or external and a wired or wireless device, can be connected to the system bus  1108  via the input device interface  1144 . In a networked environment, program modules depicted relative to the computer  1102  or portions thereof, can be stored in the remote memory/storage device  1152 . It will be appreciated that the network connections shown are example and other means of establishing a communications link between the computers can be used. 
     When used in either a LAN or WAN networking environment, the computer  1102  can access cloud storage systems or other network-based storage systems in addition to, or in place of, external storage devices  1116  as described above. Generally, a connection between the computer  1102  and a cloud storage system can be established over a LAN  1154  or WAN  1156  e.g., by the adapter  1158  or modem  1160 , respectively. Upon connecting the computer  1102  to an associated cloud storage system, the external storage interface  1126  can, with the aid of the adapter  1158  and/or modem  1160 , manage storage provided by the cloud storage system as it would other types of external storage. For instance, the external storage interface  1126  can be configured to provide access to cloud storage sources as if those sources were physically connected to the computer  1102 . 
     The computer  1102  can be operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, store shelf, etc.), and telephone. This can include Wireless Fidelity (Wi-Fi) and BLUETOOTH® wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices. 
     Wi-Fi allows connection to the Internet from a desired location (e.g., a vehicle, couch at home, a bed in a hotel room, or a conference room at work, etc.) without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., mobile phones, computers, etc., to send and receive data indoors and out, anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect devices (e.g., mobile phones, computers, etc.) to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices. 
     As utilized herein, terms “component,” “system,” “server,” and the like are intended to refer to a computer-related entity, hardware, software (e.g., in execution), and/or firmware. For example, a component can be a processor, a process running on a processor, an object, an executable, a program, a storage device, and/or a computer.

For example, computer-readable media can include, but are not limited to, magnetic storage devices, e.g., hard disk; floppy disk; magnetic strip(s); optical disk (e.g., compact disk (CD), digital video disc (DVD), Blu-ray Disc (BD)); smart card(s); and flash memory device(s) (e.g., card, stick, key drive); and/or a virtual device that emulates a storage device and/or any of the above computer-readable media. 
     In accordance with various aspects of the subject specification, artificial intelligence based systems, components, etc. can employ classifier(s) that are explicitly trained, e.g., via a generic training data, as well as implicitly trained, e.g., via observing characteristics of communication equipment, e.g., a gateway, a wireless communication device, etc., by receiving reports from such communication equipment, by receiving operator preferences, by receiving historical information, by receiving extrinsic information, etc. 
     For example, support vector machines can be configured via a learning or training phase within a classifier constructor and feature selection module, component, etc. Thus, the classifier(s) can be used by an artificial intelligence system to automatically learn and perform a number of functions, e.g., performed by a system (e.g., 100), including but not limited to: determining passive intermodulation interference corresponding to uplink signals that have been received, via a configurable cellular antenna array of a base station device, from respective wireless devices of a group of wireless devices that have been communicatively coupled to the base station device; and selecting a defined configuration of a group of cellular antenna ports of the configurable cellular antenna array to facilitate a reduction of the passive intermodulation interference corresponding to the uplink signals 
     A classifier can be a function that maps an input attribute vector, x=(x1, x2, x3, x4, xn), to a confidence that the input belongs to a class, that is, f(x)=confidence (class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to infer an action that a user, e.g., subscriber, desires to be automatically performed. In the case of communication systems, for example, attributes can be information received from access points, services, components of a wireless communication network, etc., and the classes can be categories or areas of interest (e.g., levels of priorities). A support vector machine is an example of a classifier that can be employed. The support vector machine operates by finding a hypersurface in the space of possible inputs, which the hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches include, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein can also be inclusive of statistical regression that is utilized to develop models of priority. 
     As used herein, the term “infer” or “inference” refers generally to the process of reasoning about, or inferring states of, the system, environment, user, and/or intent from a set of observations as captured via events and/or data. Captured data and events can include user data, device data, environment data, data from sensors, sensor data, application data, implicit data, explicit data, etc. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states of interest based on a consideration of data and events, for example. 
     Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources. Various classification schemes and/or systems (e.g., support vector machines, neural networks, expert systems, Bayesian belief networks, fuzzy logic, and data fusion engines) can be employed in connection with performing automatic and/or inferred action in connection with the disclosed subject matter. 
     Further, the word “exemplary” and/or “demonstrative” is used herein to mean serving as an example, instance, or illustration. For the avoidance of doubt, the subject matter disclosed herein is not limited by such examples. In addition, any aspect or design described herein as “exemplary” and/or “demonstrative” is not necessarily to be construed as preferred or advantageous over other aspects or designs, nor is it meant to preclude equivalent exemplary structures and techniques known to those of ordinary skill in the art having the benefit of the instant disclosure. 
     Furthermore, to the extent that the terms “includes,” “has,” “contains,” and other similar words are used in either the detailed description or the appended claims, such terms are intended to be inclusive—in a manner similar to the term “comprising” as an open transition word—without precluding any additional or other elements. Moreover, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. 
     The above description of illustrated embodiments of the subject disclosure, including what is described in the Abstract, is not intended to be exhaustive or to limit the disclosed embodiments to the precise forms disclosed. While specific embodiments and examples are described herein for illustrative purposes, various modifications are possible that are considered within the scope of such embodiments and examples, as those skilled in the relevant art can recognize. 
     In this regard, while the disclosed subject matter has been described in connection with various embodiments and corresponding Figures, where applicable, it is to be understood that other similar embodiments can be used or modifications and additions can be made to the described embodiments for performing the same, similar, alternative, or substitute function of the disclosed subject matter without deviating therefrom. Therefore, the disclosed subject matter should not be limited to any single embodiment described herein, but rather should be construed in breadth and scope in accordance with the appended claims below.
