City Wide Wireless

Ultra-Wideband allows consumers the hope of eliminating the maze of wires connecting electronic products in their home, including large screen displays, set-top boxes, speakers, televisions, digital video recorders, PCs/laptops, digital cameras, smartphones and more. Products that include Ultra-Wideband are expected to:

  • Build a home theater environment without cables
  • Share live multimedia content between televisions
  • Instantaneously transfer the images from a digital camera to another product
  • Quickly synchronize ultra high capacity digital audio players
  • Share wireless video between a computer and a separate monitor

Maximizing Connectivity It is the best technical implementations for capitalizing on all the benefits that Ultra-wideband has to offer. Using the widest possible bandwidth to produce the shortest possible pulses our approachs help ensure that the connections are made and that devices clearly detect the location of other devices, maximizing connectivity and quality of service.

It alos allow coherent processing over the entire frequency band while emitting nominal interfering noise such that for many applications it is virtually undetectable. The result is a high-quality experience without the jitter and drag we may see today in wireless media transmission.

The UWB technology development intends to faciliate the development of radio designs that are scalable on a variety of metrics including range, power consumption and data rates expected to achieve multi-Gbps. All the while, desiging solutions that do not require complex secondary processing which further reduces power consumption and price points making it ideal for mass-market products.

  • Advantages and disadvantages

The primary advantages of UWB are high data rates, low cost, and low power. UWB also provides less interference than narrowband radio designs, while yielding a low probability of detection and excellent multipath immunity. When combined with the 802.15.3 PAN standard, UWB will provide a very compelling wireless multimedia network for the home. It will have the ability to support multiple devices, and even multiple independent piconets, so nearby neighbors will not interfere with other UWB networks. An additional feature of UWB is that it provides for precise ranging, or distance measurement. This feature can be used for location identification in, for example, public safety applications. The basic drawback of UWB is that, under current FCC regulations, it is limited to 10, or a few 10s of meters, depending on the desired data rate. This is consistent with the intended application as a PAN technology. Whole home coverage in larger homes may require an additional networking technology, such as a metal backplane (i.e. cable, or power line) or mesh networking from room to room.

Governments are judged on how well they deliver services to their constituents and on the ability to provide those services at the low cost. For the past few years Philadelphia, like many local governments, has been using information technology and the Internet to transform how government business is done, how services are delivered and how the public sector interacts with residents, businesses and visitors. The city is aggressively pursuing wireless technology to improve service delivery and to reduce costs in many applications from mobile data terminals in police cars to hand held devices that give service delivery workers an office in the field. Broadband wireless access throughout the city will empower service delivery in ways that have only begun to be explored. It will be an essential element of the city’s technology investment for many years to come.

Once a citywide wireless network has been deployed, the goal will be to provide some level of free wireless Internet access to everyone living, working or visiting in the city. It is anticipated that some sort of tiered service levels will be created for higher levels of service and individuals and organizations will pay a fee for these higher tiers of service. How these levels of service are defined and the fees associated with them will be part of a much larger effort to create a public/private partnership to move this initiative forward.

Now the drive to unwire the living room is about to get a push. The potential is that there will be no cables hanging from your shiny new flat-panel monitor that will be attached to the wall. The answer will begin to emerge in the next year as the first UWB products reach the market. The future of the digital living room lies in the balance. This is really cool!

Dan Thanks for putting this down. I might call on you in class to share more of what you know about this topic, especially ultrawideband (UWB)
