Description:
RELATED APPLICATION 
   Related U.S. patent application Ser. No. 11/407,641, filed on even date herewith in the name of Kenneth Williams et al. and entitled “METHODS AND SYSTEMS FOR PROVIDING WIRELESS NETWORK COMMUNICATIONS,” assigned to the assignee of the present application, is hereby incorporated by reference. 
   BACKGROUND 
   I. Field of the Invention 
   The present invention generally relates to methods and systems for providing wireless communications. More particularly, the present invention relates to providing wireless communications through, for example, a utility pole mounted antenna. 
   II. Background Information 
   Wireless is a term used to describe radio transmissions via the airwaves. Wireless is a very generic term that may refer to numerous forms of non-wired transmission, including amplitude modulation (AM), frequency modulation (FM) radio, television (TV), cellular telephones, portable telephones, and wireless local area networks (LANs). Various techniques are used to provide wireless transmission, including infrared line of sight, cellular, microwave, satellite, packet radio, and spread spectrum. In some situations, in order to provide wireless communications, service providers must build large transceiver towers such as cellular telephone towers for example. Thus, the conventional strategy is for the service provider to invest large amounts of time and money to construct large transceiver towers. This often causes problems because the conventional strategy may be cost prohibitive or may not result in placing a tower in a needed location due to government regulations or due to land not being available at the needed location. 
   In view of the foregoing, there is a need for methods and systems for providing wireless communications more optimally. Furthermore, there is a need for providing wireless communications through, for example, a utility pole mounted antenna. 
   SUMMARY 
   Consistent with embodiments of the present invention, systems and methods are disclosed for providing wireless communications through, for example, a utility pole mounted antenna. 
   In accordance with one embodiment, a method for providing wireless communications, the method comprising receiving first data from a wire line network at a transceiver placed at a location on the wire line network, the location comprising a place where the wire line network is present, where electrical power for the transceiver is present, and where a service provider of the wireless communications has a legal right to locate the transceiver and transmitting the first data wirelessly from the transceiver through an antenna wherein the transceiver and the antenna are located on a utility pole. 
   According to another embodiment, a system for providing wireless communications, the system comprising a transceiver configured to be located on a utility pole, the transceiver operative to receive first data from a wire line network at a location on the wire line network, the location comprising a place where the wire line network is present, where electrical power for the transceiver is present, and where a service provider of the wireless communications has a legal right to locate the transceiver and to transmit the first data wirelessly from the transceiver through an antenna configured to be located on the utility pole.

   DETAILED DESCRIPTION 
   The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several exemplary embodiments and features of the invention are described herein, modifications, adaptations and other implementations are possible, without departing from the spirit and scope of the invention. For example, substitutions, additions or modifications may be made to the components illustrated in the drawings, and the exemplary methods described herein may be modified by substituting, reordering or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the invention. Instead, the proper scope of the invention is defined by the appended claims. 
   Systems and methods consistent with embodiments of the present invention provide wireless communications through, for example, a utility pole mounted antenna. Consistent with embodiments of the present invention, instead of building a cell tower, for example, a service provider may contact a local utility (e.g. a electric utility) in order to construct a “mini tower”. For example, the service provider may have a wire line network attached to a utility pole owned by the electric utility. The service provider may offer to pay the expenses for converting the utility pole to, for example, a hollow metal pole. The service provider may then place an antenna (above a high-voltage electric line) on the hollow metal pole&#39;s top. Furthermore, the service provider may run a cable from a transceiver to the antenna, the transceiver and the wire line network mounted on the hollow metal pole below the high-voltage electric line. The cable may run substantially vertically through the hollow metal utility pole&#39;s interior to the antenna. The antenna may not comprise a big array of antenna, but rather may comprise a few flat panels. In this way, an unobtrusive mini tower may be constructed in a location where power and the wire line network are located without having to purchase land, get a Federal Aviation Administration (FAA) clearance, or get public approval. 
   Consistent with embodiments of the invention, wired broadband networks, such as coaxial cable television networks, are pervasive, passing most homes and businesses in the communities server by a service provider. Such networks may be located, for example, in public or private utility rights-of-way. In addition, such networks may have a network wide data service enabled throughout all markets, comprising, for example, data over cable service interface specification (DOCSIS) high speed data service. Furthermore, such networks may have electric power available, for example, on or near the coaxial network. 
   Combining the advantage of access via the right-of-way, pervasive network power, and a ubiquitous data service, transceivers may be placed on the network that may enable, for example, construction of a mini tower. The transceivers may combine, for example, a cable modem and a wireless access point radio in an environmentally hardened enclosure and be energized by the coaxial network power. Because the transceivers may be located in a utility right-of-way, the service provider may not have to obtain permission to install the transceivers (even at a customer premises) or share revenue with another enterprise. 
   An embodiment consistent with the invention may comprise a system for providing wireless communications. The system may comprise a transceiver configured to be located on a utility pole. The transceiver may be operative to receive first data from a wire line network at a location on the wire line network. The location may comprise a place where the wire line network is present, a place where electrical power for the transceiver is present, or a place where a service provider of the wireless communications has a legal right to locate the transceiver. Moreover, the transceiver may be operative to transmit the first data wirelessly from the transceiver through an antenna configured to be located on the utility pole. 
   Another embodiment consistent with the invention may comprise a system for providing wireless network communications. The system may comprise a memory storage for maintaining a database and a processing unit coupled to the memory storage. The processing unit may be operative to receive first data from a wire line network at a location on the wire line network. The location may comprise a place where the wire line network is present, a place where electrical power for the transceiver is present, or a place where a service provider of the wireless communications has a legal right to locate the transceiver. Moreover, the processing unit may be operative to transmit the first data wirelessly from the processing unit through an antenna configured to be located on the utility pole. 
   Consistent with an embodiment of the present invention, the aforementioned transceiver, memory, processing unit, and other components may be implemented in a wireless communications providing system, such as an exemplary wireless network communications providing system  100  of  FIG. 1 . Any suitable combination of hardware, software, and/or firmware may be used to implement the transceiver, memory, processing unit, or other components. By way of example, the memory, processing unit, or other components may be implemented with any of transceivers  145 ,  150 ,  155 ,  160 , and  165 , in combination with system  100 . The aforementioned system and processors are exemplary and other systems and processors may comprise the aforementioned transceiver, memory, processing unit, or other components, consistent with embodiments of the present invention. 
   Furthermore, embodiments of the invention may be practiced in an electrical circuit comprising discrete electronic elements, packaged or integrated electronic chips containing logic gates, a circuit utilizing a microprocessor, or on a single chip containing electronic elements or microprocessors. The invention may also be practiced using other technologies capable of performing logical operations such as, for example, AND, OR, and NOT, including but not limited to mechanical, optical, fluidic, and quantum technologies. In addition, the invention may be practiced within a general purpose computer or in any other circuits or systems. 
   By way of a non-limiting example,  FIG. 1  illustrates system  100  in which the features and principles of the present invention may be implemented. As illustrated in the block diagram of  FIG. 1 , system  100  may include a wire line network  105  placed, for example, on utility poles  110 . In one embodiment, wire line network  105  may comprise an overhead cable television line placed on poles by itself or along with facilities belonging to other utilities. Utility poles  110  may be owned by a service provider who owns wire line network  105  or by another enterprise such as an electric or telecommunications utility company. Alternately, wire line network  105  may comprise an underground line place, for example, in a ditch by itself or including facilities belonging to other utilities. Wire line network  105  and utility poles  110  may be placed within a utility right-of-way with boundaries  112 . Wire line network  105 , for example, may comprise, but is not limited to, any one or more of a coaxial cable network, a hybrid fiber-coax (HFC) network, a fiber optic network, or a twister pair network. Furthermore, wire line network may use any one or more of asynchronous transfer mode (ATM), a synchronous optical network (SONET) transmission system, Ethernet, and DOCSIS. The aforementioned are exemplary, and wire line network  105  may comprise any type of network using any type of protocol. 
   Ethernet is a widely used local area network (LAN) access method, defined by the IEEE as the 802.3 standard. DOCSIS is a set of standards for transferring data via cable TV and cable modems. SONET is a fiber-optic transmission system for high-speed digital traffic employed by telephone companies and common carriers with speeds range from 51 Mbps to 40 Gbps. ATM is a network technology for both LANs and wide area networks (WANs) that supports realtime voice and video as well as data. The ATM topology uses switches that establish a logical circuit from end-to-end, that may guarantee quality of service (QoS). 
   Wire line network  105  may be pervasive throughout a community. For example, wire line network may run through a certain geographic area and be capable of serving nearly all homes, businesses, or other enterprises within the community with any type wire line services. For example, wire line network  105  may comprise a cable television coaxial network capable of reaching all or nearly all homes, businesses, or other enterprises within the community. 
   Wire line network  105  may serve first end use location  115  and second end use location  120  with wire service drops  125  and  130  respectively. End use location  135  and  140  may be close enough to be serviced by wire line network  105 , but no wire service drop has yet been extended to either of these end use locations. For example, users at these locations my not have ordered wired service yet from the service provider operating wire line network  105 . 
   As stated above, system  100  may also include transceivers  145 ,  150 ,  155 ,  160 , and  165 . Any of these transceivers may be operative to receive first data from wire line network  105  a location on wire line network  105 . Any of transceivers  145 ,  150 ,  155 ,  160 , and  165  may be placed at a location comprising a place where wire line network  105  is present, where electrical power for the respective transceiver is present, and where the service provider of the wireless network communications has a legal right to locate the transceiver. Each of transceivers  145 ,  150 ,  155 ,  160 , and  165  may include a respective range  175 ,  180 ,  185 ,  190 , and  195  in which each transceiver can transmit and receive data. The ranges for transceivers  145 ,  150 ,  155 ,  169 , and  165  may or may not overlap. For example, because a wireless device  170  is within range  180  corresponding to transceiver  150 , transceiver  150  may transmit the first data wirelessly to wireless device  170 . Likewise, transceiver  150  may receive second data wirelessly from wireless device  170 . Each of transceivers  145 ,  150 ,  155 ,  160 , and  165  may be operative to transmit and receive data wirelessly using, for example, one of Wi-Fi and Wi-Max. The aforementioned are exemplary, and other transmitting and receiving processes may be used. 
   Wireless device  170  need not be located in end use locations, but can be located outside end use location  115  (e.g.  170 ′.) Wireless device  170  may communicate with any of transceivers  145 ,  150 ,  155 ,  160 , and  165  as long as it is within any one or more of ranges  175 ,  180 ,  185 ,  190 , and  195 . Wireless device  170  may comprise, but is not limited to, a cellular telephone, a computer, a two-way radio, and a device capable of receiving packetized data. The aforementioned are exemplary and wireless device  170  may comprise other devices. Furthermore, the first data and/or the second data may comprise one of cellular telephone traffic transported by wire line network  105 , two-way radio traffic transported by wire line network  105 , and packetized data. 
   Any of transceivers  145 ,  150 ,  155 ,  160 , and  165  may comprise a combined radio and cable modem configured to operate in an outdoor environment. For example, any of the transceivers may be configured to operate in direct sunlight, in rain, in extremely low and extremely high temperatures. The electrical power for any of transceivers  145 ,  150 ,  155 ,  160 , and  165  may be provided from wire line network  105  or from other electrical power sources. Any of transceivers  145 ,  150 ,  155 ,  160 , and  165  may be located within a utility right-of-way, on a utility pole, at a utility service termination point, out-of-doors, or less than 1000 feet from any wireless device. The aforementioned are exemplary, and any of transceivers  145 ,  150 ,  155 ,  160 , and  165  may be located: i) where wire line network  105  is present; ii) where electrical power for transceiver  150  is present; and iii) where the service provider of the wireless network communications has a legal right to locate the transceiver. The legal right to locate any of transceivers  145 ,  150 ,  155 ,  160 , and  165  may comprise one of a right-of-way easement and a right-of-way joint use agreement with an enterprise having a right to locate facilities at the location. For example, utility right-of-way with boundaries  112  may indicate an area in which the service provider of the wireless network communications has a legal right to locate any of transceivers  145 ,  150 ,  155 ,  160 , and  165 . The aforementioned are exemplary, and the legal right to locate any of transceivers  145 ,  150 ,  155 ,  160 , and  165  may comprise any interest in real property. 
     FIG. 2A  shows transceiver  150  of  FIG. 1  in more detail. Transceivers  145 ,  155 ,  160 , and  165  may comprise a similar structure. As shown in  FIG. 2A , transceiver  150  may include a processing unit  225  and a memory  230 . Memory  230  may include a wireless communications software module  235  and a wireless communications database  240 . A radio  245  may communicate with processing unit  225  and send and receive data through antenna  260 . Transceiver  150  may connect to antenna  260  through cable  250 . Transceiver  150  may connect to wire line  105  using modem  255 . While executing on processing unit  225 , wireless communications software module  235  may perform processes for providing wireless communications, including, for example, one or more of the stages of method  300  described below with respect to  FIG. 3 . Alternatively, the function of processing unit  225  and memory  230  may be practiced, for example, in an electrical circuit comprising discrete electronic elements, packaged or integrated electronic chips containing logic gates, a circuit utilizing a microprocessor, or on a single chip containing electronic elements or microprocessors. 
     FIG. 2B  shows a potion of cable  250  passing substantially vertically through an interior of a utility pole  257 . Transceiver  150  may mount to the side of utility pole  257  and antenna  260  may mount near or on the top of utility pole  257 . Utility pole  257  may be metal, hollow, and may be hermetically sealed. The aforementioned are exemplary and utility pole  257  may include other features and configurations. Transceiver  150  and wire line network  105  may be mounted on utility pole  257  below a high-voltage power line  265 . Antenna  260  may be mounted above high-voltage power line  265 . Moreover, utility pole  257  may comprise any type of vertical structure and is not limited to a pole owned by any type enterprise. Furthermore, high-voltage power line  265  may provide power to any of transceivers  145 ,  150 ,  155 ,  160 , and  165 , through, for example, a transformer (not shown). 
   Any of transceivers  145 ,  150 ,  155 ,  160 , and  165  (“the transceivers”) included in system  100  may be implemented using a personal computer, network computer, mainframe, or other similar microcomputer-based workstation. The transceivers may though comprise any type of computer operating environment, such as hand-held devices, multiprocessor systems, microprocessor-based or programmable sender electronic devices, minicomputers, mainframe computers, and the like. The transceivers may also be practiced in distributed computing environments where tasks are performed by remote processing devices. Furthermore, any of the transceivers may comprise a mobile terminal, such as a smart phone, a cellular telephone, a cellular telephone utilizing wireless application protocol (WAP), personal digital assistant (PDA), intelligent pager, portable computer, a hand held computer, a conventional telephone, or a facsimile machine. The aforementioned systems and devices are exemplary and the transceiver may comprise other systems or devices. 
     FIG. 3  is a flow chart setting forth the general stages involved in an exemplary method  300  consistent with the invention for providing wireless network communications using system  100  of  FIG. 1 . Exemplary ways to implement the stages of exemplary method  300  will be described in greater detail below. Exemplary method  300  may begin at starting block  305  and proceed to stage  310  where transceiver  150  may receive first data from wire line network  105 . Transceiver  150  may be placed at a location on wire line network  105  comprising a place: i) where wire line network  105  is present; ii) where electrical power for transceiver  150  is present; and iii) where a service provider of the wireless network communications has a legal right to locate transceiver  150 . For example, wire line network  105  may comprise a wired broadband network, such as a coaxial cable television network. The cable television network may be pervasive, passing most homes and businesses in the communities server by the service provider. Moreover, the cable television network may be located, for example, in a public or private utility right-of-way. In addition, the cable television network may have a network wide data service enabled throughout all markets, comprising, for example, DOCSIS high speed data service. Also, the cable television network may have electric power available, for example, on the coaxial network. 
   Combining the advantage of access via the right-of-way, pervasive network power, and a ubiquitous data service, transceiver  150  may be placed on wire line network  105  that may enable, for example, cellular telephone traffic transportation or wireless fidelity (Wi-Fi) service on the fly in any part of wire line network  105 . Transceiver  150  may combine, for example, a cable modem and a wireless access point radio in an environmentally hardened enclosure and be energize by wire line network  105  or another power source at transceiver  150 &#39;s location. Because transceiver  150  may be located in a utility right-of-way, the service provider may not have to obtain permission to install transceiver  150  (even at a customer premises) or share revenue with another enterprise. The service provider branded wireless service could be enabled in almost any location along wireline network  105 . 
   From stage  310 , where transceiver  150  receives first data from wire line network  105 , exemplary method  300  may advance to stage  320  where transceiver  150  may transmit the first data wirelessly from transceiver  150  to wireless device  170 . For example, the first data may comprise a web page or e-mail directed to an internet protocol (IP) address associated with wireless device  170 . The first data may be routed over the internet, for example, through wire line network  105 , to transceiver  150 . Furthermore, the first data may comprise cellular telephone traffic transported by wire line network  105  to wireless device  170 . Transceiver  150  may receive the first data through modem  255 . Then transceiver  150  may transmit the first data using radio  245 . In transmitting the first data, transceiver  150  may use, for example, Wi-Fi or cellular telephone processes and protocols. The aforementioned are exemplary and others may be used. 
   Once transceiver  150  transmits the first data wirelessly to wireless device  170  in stage  320 , exemplary method  300  may continue to stage  330  where transceiver  150  may receive second data at transceiver  150  wirelessly from wireless device  170 . For example, the second data may comprise information returned in response the aforementioned web page or an e-mail directed from the IP address associated with wireless device  170 . Furthermore, the second data may comprise cellular telephone traffic from wireless device  170  to be transported back through wire line network  105 . After transceiver  150  receives second data in stage  330 , exemplary method  300  may then end at stage  340 .
