BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present invention relates to wireless communications facilities, and more particularly to techniques for mounting and camouflaging wireless communications antennas and equipment to be deployed in an appropriate setting. 
         [0003]    2. Description of the Related Art 
         [0004]    At the present time, it is difficult to get wireless communication coverage in coastal areas and inland waterways at or near the water, often due to difficulty in obtaining approvals for constructing wireless communication facilities. There is a need for some means by which wireless communication providers can provide access to these currently underserved areas. The available choices for mounting antennas are limited by height, topography, man-made and natural clutter, and other obstructions. The available choices for constructing wireless communications facilities at or near a waterfront are far more limited. 
         [0005]    Currently, the available conventional wireless communication facility installations include the following: 1) rooftop installations; 2) tower structures (such as lattice, monopole, guyed and high-tension towers); and 3) water tanks. These conventional installations are not always available to wireless communications providers. The reasons a conventional site may not be suitable or available could include municipal zoning code restrictions. 
         [0006]    A further concern regarding conventional wireless communication facilities is the possibility of damage that arises when the wireless equipment is exposed to the elements. Moreover, in a waterfront environment, sand, salt, wind and water can pose a substantial risk of corrosion, leading to the possibility of both mechanical and electrical failure. Finally, a further concern regarding conventional wireless communication facilities is the possibility that the wireless equipment could be stolen or damaged by vandals. 
         [0007]    There is therefore a need for a product or system that provides sufficient height while being a discreet and secure housing for wireless communication antennas and equipment in an underserved area. 
       SUMMARY 
       [0008]    A system for mounting wireless equipment for transmission and reception of radio frequencies comprising a hull, a mast attached to the hull, one or more wireless antennas attached to the top of the hollow mast, and one or more compartments within the hull suitable for mounting transmission and reception equipment. The system will generally sit at drydock to maintain consistency in the broadcast and reception of radio frequencies, as well as to allow for ease of access for maintenance. However, in certain instances, the Cellboat may also be deployed in the water. 
         [0009]    One or more lockable access doors are installed in the side of the hull, providing access to the compartments. Cables run between the antennas and the equipment through the hollow mast, and are supported by a friction hoist grip. Cables also connect the equipment to electrical power and landline telephone connections on land. Alternatively, when the Cellboat is deployed in the water, the access doors will be located on the top deck of the Cellboat. 
         [0010]    These and other features and advantages will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings and incorporated herein.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0021]    Presented herein is a means by which wireless communication coverage can be provided in coastal areas and inland waterways at or near the water. A Cellboat, made according to the present principles, keeps equipment safe from damage and theft, while providing wireless communication access in previously underserved areas. The Cellboat will provide a mobile stealth solution to sitting wireless communications facilities in those areas where conventional solutions are not available, as it will not be subject to the same municipal zoning code restrictions placed on the development of conventional wireless communications facilities. 
         [0022]    The result is that the Cellboat product provides sufficient height and stealth quality such that it is indistinguishable to passers-by and the surrounding community from a traditional sailboat. 
         [0023]    Referring now in detail to the figures in which like numerals represent the same or similar elements and initially to  FIG. 1 , the invention comprises a boat hull  102 , to which is attached a hollow mast  104 . An antenna  103  (for example, a whip antenna) is attached at the top of the mast. A compartment  106  is disposed in the hull  102 . The compartment may simply open into the existing cockpit area  112  of the hull, as shown in  FIG. 2  below, or it may be separately contained. Mounted in the compartment  106  is the wireless transceiver equipment  108  (for example, a base transceiver station, a telephone company 66-block, and electric circuit breakers). A cable  110  (for example, coaxial cable) is connected to the antenna  103  and to the wireless transceiver equipment  108  and is routed down through the hollow mast  104 . The overall appearance of the Cellboat system should be that of a traditional sailboat. While elements relating to the Cellboat&#39;s appearance are not directly functional, they further serve the purpose of disguising the stealth qualities of the Cellboat and the true purpose of the system. 
         [0024]    Referring to  FIG. 2 , an access door  202  is disposed in the side of the hull  104 , providing access to the compartment  106 . The wireless transceiver equipment  10 B is optionally mounted directly to the access door  202 . This will allow for a worker to have direct access to the equipment  108  from the ground from access door  202  for maintenance. The access door may be made weatherproof or even waterproof by using a rubber seal or gasket (not shown) around the rim of the access door, as well as optionally including active water removal devices (such as pumps). 
         [0025]    Referring to  FIG. 3 , the access door  202  is hinged at the bottom and opens out to a 90 degree angle from the hull  102 . The cable  110  is looped, so as to provide additional slack for when the access door  202  is opened if the wireless transceiver equipment  108  is mounted to the access door  202 . A means for suspension  302 , such as a cable or a rod, holds the access door  202  parallel to the ground when it is open. The access door  202  may additionally be locked when in the upright position in order to provide additional security. 
         [0026]    Referring to  FIG. 4 , the wireless antenna  103  is mounted at the top of the mast  104 . The mast  104  has a hole  402  near the top. The cable  110  is attached to the antenna  103  and enters the mast through the hole  402 . A weatherproof gasket (not shown) seals the space around the cable  110  and the rim of the hole  402 . This gasket is useful for preventing the accumulation of water and debris in the mast  104 . In order to reduce tension on its connection to the antenna  103 , the cable  110  is suspended by a friction hoist grip  406  which is hung from a hook  404 . The friction hoist also prevents the cable  110  from being abraded and pinched by the hole  402 . The hook  404  in turn is attached to the mast  104 . 
         [0027]    Referring to  FIG. 5 , the mast  104  has a hole  502  at the bottom, and the cable  110  exits the mast through hole  502 . A weatherproof gasket (not shown) seals the space between the cable  110  and the rim of the hole  502 . As in  FIG. 4 , this gasket is useful for preventing the accumulation of water and detritus in the mast  104 . 
         [0028]    Referring to  FIG. 6 , the hull  102  may be stored at a dock  602 , either in the water or in drydock. Being stationed in drydock allows for access to the access door  202 , and keeps the compartment  106  from taking on water, while being in the water makes the system less accessible and more convincing in its disguise. Being at a dock (whether dry or wet) provides easy access to electric power and telephone company connections. Cables  604  connect the wireless transceiver equipment to a weatherproof electric/telephone service connection point  606  on the dock  602 , which provides the equipment with electric power and a connection to the telephone company. The cables  604  enter the hull  102  by way of weatherproof connection points  608  on top of the hull  102 . 
         [0029]    Referring to  FIG. 7 , an alternative embodiment is shown where an access door  702  is disposed between the cockpit area and the compartment  106 . In this embodiment, the wireless transceiver equipment  108  is mounted to the hull  102 . In addition, the cable  110  need not be looped before ascending mast  104 , as the wireless transceiver equipment is no longer mounted to an access door. 
         [0030]    Referring to  FIG. 8 , an alternative embodiment is shown where a panel antenna  802  is used instead of a whip antenna. The cable  110  attaches to the back of the antenna  802 , using the same hole  402  and hoist grip  406  described above. 
         [0031]    Referring to  FIG. 9 , an alternative embodiment is shown using a plurality of panel antennas  802 . By arranging panels around the mast  104 , the advantages of a panel antenna may be combined with the 360° coverage of a whip antenna.  FIG. 9  depicts three panel antennas, with an angular displacement of 120°, but other arrangements and numbers of panels are contemplated. 
         [0032]    It is contemplated that the present invention may be created by retrofitting an existing boat, or by assembling it so as to exclude unnecessary components. An embodiment of the invention is designed to stay in permanent drydock, facilitating access for maintenance and lowering the cost of waterproofing. However, it is also contemplated that the system may be made sufficiently waterproof such that the system may float in the water near a dock. 
         [0033]    Having described preferred embodiments of a system and method (which are intended to be illustrative and not limiting), it is noted that modifications and variations can be made by persons skilled in the art in light of the above teachings. It is therefore to be understood that changes may be made in the particular embodiments disclosed which are within the scope and spirit of the invention as outlined by the appended claims. Having thus described aspects of the invention, with the details and particularity required by the patent laws, what is claimed and desired protected by Letters Patent is set forth in the appended claims.
