The invention claimed is:
This patent application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 61/261,649, entitled “Self-Contained Data Communication System Nodes as Stand-Alone Pods or Embedded in Concrete Walkways and in Walls at Public Venues Including Sports and Entertainment Venues,” which was filed on Nov. 16, 2009, the disclosure of which is incorporated herein by reference in its entirety.
The present invention is generally related to a wireless communications networks. More particularly, the present invention is related to wireless data communications system communications nodes set up to establish a communication network within public venues including sports and entertainment venues. The present invention is also related to wireless data communications systems including communications nodes comprising a communication network within a public venue supporting access to video and data by hand held devices also located within the public venue.
Wireless data communications technology has now found its place in sports and entertainment venues over the past decade. Video and data related to an event at sports venues is now widely available on portable hand held devices such as mobile phones and proprietary devices that can be rented at the sports venues. Wireless communication can be provided to handheld devices via cellular and 802.11 (Wi-Fi) systems. In addition to live video from different perspectives, such as that provided to spectators at sporting events by Kangaroo Media, Inc, of Montreal, Canada (www.kangaroo.tv), social networking, gaming and vending applications are also being provided to spectators. Such systems and applications are well documented in U.S. Pat. Nos. 7,149,549, 7,376,388 and 7,620,426, which are herein incorporated by reference for their teaching.
New sports and entertainment venues are now being designed and built to incorporate wireless data communications infrastructure in order to enable enhanced spectator experiences. Examples of such venues include Yankee Stadium, in New York, and Dallas Cowboy Stadium, in Irving, Tex., which have both been enabled with substantial investments in Cisco wireless network technology to enable video and data access for venue attendees using personal hand held devices.
Although new stadiums are being built with wireless capabilities, still many entertainment venues are older and lack the “built-in” wireless data communications infrastructure necessary to support large scale hand held device access to live video recorded by cameras at entertainment venues and associated entertainment data. Furthermore, some entertainment venues may only require temporary installations of wireless video and data communications capabilities for a special event. For the foregoing reasons, there is a need to provide systems that can enable video and data communications with multiple wireless hand held devices for older entertainment venues, and/or for any public venues where data access is only needed temporarily or long-term. The present invention provides a solution for this need.
Accordingly, it is a feature of the present invention to provide self-contained communications system nodes establishing a wireless data communication network within public venues, such as sports and entertainment venues, for providing video and data to hand held devices located at said venues.
It is also a feature of the present invention to provide self-contained communications system nodes as stand-alone pods at public venues such as sports and entertainment venues.
It is also feature of the present invention to provide self-contained communications system nodes for embedded use in concrete walkways and in walls at public venues such as sports and entertainment venues.
Accordingly, it is a feature of the present invention to provide a system supporting the communications of video and data to hand held devices located within a public venue is disclosed. At least one pod including wireless communications electronics (e.g., wireless access point, repeaters) and an integrated antennae that can be deployed as a communications node within the public venue and can provide data including video from at least one server to hand held wireless devices located in the public venue through a data network.
It is another feature that the system supporting the communications of video and data to hand held devices located within a public venue to include more than one pod deployed throughout the public venue.
It is yet another feature that communications pods can each further include a rechargeable power source sustaining self-contained operation of the wireless communication electronics.
It is another feature that each communications pod can further include a solar cell providing an electrical power to charge the rechargeable power source contained in the pod.
It is another feature of the present invention that communications pods can be embedded in a wall or floor surface of said public venue.
It is yet another feature of the present invention that communications pods can further comprise of a core hole plug that includes the wireless communications electronics therein and that such pods can be embedded in a wall or floor surface of said pubic venue.
Access points, which are often interconnected by cabling, generally play a dominant role in providing radio frequency (RF) coverage in most wireless LAN (WLAN) deployments. Wireless repeaters, though, are an alternative way to extend the range of an existing WLAN instead of adding more access points. There are very few stand-alone 802.11 wireless repeaters on the market, but some access points have a built-in repeater mode. The wireless communications electronics representing access points and wireless repeaters will be referred to herein as communications system nodes, or simply as communications nodes.
In general, a repeater simply regenerates a network signal in order to extend the range of the existing network infrastructure. A WLAN repeater does not physically connect by wire to any part of the network. Instead, it receives radio signals (802.11 frames) from an access point, end user device, or another repeater and retransmits the frames. This makes it possible for a repeater located in between an access point and distant user to act as a relay for frames traveling back and forth between the user and the access point.
As a result, wireless repeaters are an effective solution to overcome signal impairments such as RF attenuation. For example, repeaters provide connectivity to remote areas that normally would not have wireless network access. In sports and entertainment venue deployments, temporary placement and large areas requiring coverage can result in access points that don't quite cover areas where spectators using hand held devices desire connectivity. The placement of a repeater between the covered and uncovered areas, however, can provide connectivity throughout most of the venue space. The wireless repeater fills holes in coverage, enabling seamless roaming. Although the most modern venues includes built-in wireless infrastructure, older venues often require retrofitting to incorporate wireless communications equipment, or the equipment will only be temporary and must be installed just before an event. Temporary use will be typical with multi-purpose venues. The present invention provides a system that can simplify the temporary or retrofit placement of wireless data communications equipment as pods throughout sports and entertainment venues.
Communications electronics can be provided within sports and entertainment venues in the form of self-contained pods. As illustrated in
As illustrated in the top perspective view of
In some venues, it may be desirable to more permanently install communications pods 100 for ongoing use. Such can be the case wherein an older sports venue requires wireless communications infrastructure and the older venue must be retrofitted to incorporate the wireless communications infrastructure with little aesthetic and space encumbrances on the venue. As shown in
A core hole plug assembly has been described in U.S. Pat. No. 6,662,490, issued to Aesch, Jr., can provide a carrier for the communications electronics 110. As such, a core hole plug can serve as an embedded pod 100. The pod 100 in the form of a core hole plug assembly can also include a rechargeable power source 130 and embedded antennae 120. Alternatively, power can be provided to the embedded pod via wiring accessible within the flooring 310 or walls 320. A solar cell 140 can also be optionally provided at the surface of the pod to provide a trickle charge to rechargeable power source 130, if provided in the pod.
The '490 patent describes a core hole plug for covering and sealing a hole in a paved surface, wall or other structure. As described in the '490 patent, many locations such as urban environments, office parks, shopping centers, offices, and industrial and commercial buildings are surrounded in whole or in part with paved surfaces such as but not limited to concrete paving, asphalt paving, stone or brick paving, and paving made of similar materials. The paving takes many forms, e.g. driveways, sidewalks, etc. A typical paving is a concrete slab or other paving material about four to eight inches thick. Offices, warehouses, and other industrial and commercial buildings often have solid or hollow walls made of concrete, block or other materials of various thicknesses e.g. walls having thicknesses of six to eight inches or more.
Although core holes or other holes are typically about three inches or slightly greater in diameter, the diameter and depth of a communications pod 100 can vary depending on the required size of the internal compartment to accommodate the modules (e.g., battery, electronics) to support wireless communications.
Core holes are sometimes formed in paved surfaces and walls for various purposes, such as but not limited to, tests to determine if the paving or wall meets specifications, the treatment of cockroaches, ants, and various other pests, the passage of utilities through the walls, etc. Once a core has been taken from or a hole otherwise made in a paved surface, wall or other structure there usually is a need to cover and seal the hole, e.g. after a core sample has been taken, after pests have been treated, prior to the installation or after the removal of utilities, etc. Since core hole plugs are relatively easy to install and unobtrusive or inconspicuous, rather than patching these holes, these holes are frequently covered and sealed with core hole plugs. In addition to being easy and quick to install and unobtrusive or inconspicuous, the core hole plugs have another advantage over patching the holes. Should there be a need to later gain access to the interior of the hole, the core hole plug can be removed.
A core hole plug assembly 400 typically includes a cover plate 430; a deformable, resilient expansible plug 432; a compression plate 434; and a bolt and nut assembly 436 with a bolt 438 and a nut 440. The expansible plug 432 is cylindrical with a tubular sidewall 442. Preferably, the compression plate 434 is a circular disk and the nut 440 of the bolt and nut assembly 436 is welded or otherwise nonrotatably affixed to and integral with the compression plate 434. The compression plate 434 is permanently and non-rotatably secured to the lower end portion 444 of the expansible plug 432, preferably, by being molded into or otherwise completely embedded within the lower end portion 444 of the expansible plug 432 so that the compression plate 434 does not rotate relative to the expansible plug. Preferably, the upper end of the expansible plug 432 is permanently and nonrotatably secured to the underside of the cover plate 430, e.g. adhesively or otherwise bonded to the underside of the cover plate, so that the expansible plug does not rotate relative to the cover plate. With the nut 440 of the bolt and nut assembly 436 nonrotatably affixed to the compression plate 434, the compression plate 434 nonrotatably secured to the lower end portion 444 of the expansible plug 432, and expansible plug 432 nonrotatably affixed to the underside of the cover plate 430, these components of the core hole plug assembly 400 function as a unit so that the bolt 438 of the bolt and nut assembly 436 can be threaded into or out of the nut 440 to move the compression plate 434 relative to the cover plate 430 (toward or away from the cover plate 430).
The bolt 438 of the bolt and nut assembly 436 passes down through a hole in the cover plate, through the expansible plug 432 and is threaded into the nut 440 affixed to the compression plate 434. When the bolt and nut assembly 436 is tightened by threading the bolt 438 into the nut 440, the compression plate 434 is drawn toward the cover plate 430 to compress the expansible plug 432 between the compression plate 434 and the cover plate 430 and expand the expansible plug 432 in diameter. When the bolt and nut assembly 436 is loosened by partially unthreading the bolt 438 from the nut 440, the compression plate 434 is moved away from the cover plate 430 and permits the resilient expansible plug 432 to return to its original shape and diameter.
In use, as the expansible plug 432 is compressed by tightening the bolt and nut assembly 436 and drawing the compression plate 434 toward the cover plate 430, the expansible plug 432 expands in diameter to force the outside surface of the expansible plug 432 into contact with the sidewall of a hole. This secures the core hole plug assembly 420 in place and forms a seal between the outside surface of expansible plug 432 and the sidewall of the hole. When the bolt and nut assembly 436 is loosened and the expansible plug 432 is allowed to return to its initial shape and diameter, the outside surface of the expansible plug 432 draws away from the sidewall of the hole and the core hole plug assembly 400 can be easily removed as a unit without fear of losing a nut, compression plate, or plug down the hole or wall cavity.
The cover plate 430 and the compression plate can be made of stainless steel, aluminum, a durable polymeric material, a durable fiberglass reinforced polymeric material or some other suitable durable, preferably noncorrosive and chemical resistant material. If made of metal, the cover plate 430 can serve as the antennae for the pod 100 for carrying out wireless communication, in accordance with the present invention. The bolt and nut assembly 436 can be made with a stainless steel bolt 438 and a stainless steel nut 440. Various heads may be used on the bolt 438 of the bolt and nut assembly 436 so that the bolt and nut assembly can be tightened and loosened using a wrench, an Allen wrench, a screwdriver, or other tool. Preferably, there can be a recess in the upper surface of the cover plate 430 surrounding the hole through which the bolt passes. The head of the bolt 438 is received within the recess so that the head of the bolt is flush or substantially flush with the upper surface of the cover plate 430. In accordance with the present invention, electronics 110 circuitry (e.g., circuit boards, solar cell 140) and batteries 130 can be designed to accept a center bolt.
The expansible plug 432 can be made of a deformable and resilient polymeric material, such as but not limited to a deformable, resilient thermoplastic rubber or polymeric material, which has the resilience to return to its original diameter and shape when the expansible plug 432 is not under compression. Preferably, the material forming the expansible plug 432 is also durable and chemical resistant. The cover plate 430 is greater in diameter than the diameter of the expansible plug 432 and any hole the core hole plug assembly 400 is to seal. The compression plate 434 is typically made of stainless steel and is a little less than but about the same diameter as the diameter of the expansible plug 432. The cover plate 430 is typically about 3½ to 4 inches in diameter. When not compressed, the expansible plug 432 is typically about ⅛ to about ¼ of an inch less in diameter than the diameter of the hole with which the core hole plug assembly 400 is to be used (e.g. about 2¾ to about 2⅞ inches in diameter for use with a hole about 3 inches in diameter) and about 1 to 1½ inches in height.
With the compression plate 434 completely embedded within the lower end portion 444 of the expansible plug 432, the polymeric material forming the expansible plug forms a lowermost disk shaped layer of the assembly. A top view of the top surface of the cover plate is shown in
