WiMAX technology can provide coverage in both LOS and NLOS conditions.
NLOS has many implementation advantages that enable operators to deliver broadband data to a wide range of customers.
WiMAX technology has many advantages that allow it to provide NLOS solutions, with essential features such as OFDM technology, adaptive modulation and error correction.
Furthermore, WiMAX has many optional features, such as ARQ, sub-channeling, diversity, and space-time coding that will prove invaluable to operators wishing to provide quality and performance that rivals wireline technology.
For the first time, broadband wireless operators will be able to deploy standardized equipment with the right balance of cost and performance; choosing the appropriate set of features for their particular business model.
WiMAX will indeed accomplish a multitude of consumer applications that will overshadow last mile communication links. Applications such as streaming video to PDA’s, cell phones, and portable PCs are one example. How about downloading music on demand to future versions of the ever-popular iPod or your favorite TV programs to your laptop while you are on a train speeding along at 75 miles per hour? The list goes on and on. Broadband will be a huge revenue engine for the providers who take heed and plan for the future. <full text>
Questions: Why are the wireless application mentioned above not doable by GPRS/3G, or Wi-Fi in terms of their specifications?
Wireless Location Privacy Protection B Schilit, J Hong, M Gruteser - www-2.cs.cmu.edu Location-based services are emerg- ing as the next killer app in personal wireless devices, but there are few safe- guards on location privacy. In fact, the demand for improved public safety is pushing regulation in the opposite direction.
PeopleNet: engineering a wireless virtual social network M Motani, V Srinivasan, PS Nuggehalli People often seek information by asking other people even when they have access to vast reservoirs of information such as the Internet and libraries. This is because people are great sources of unique information, especially that which is location-specific, community-specific and time-specific. Social networking is effective because this type of information is often not easily available anywhere else.
The Effects of a Wireless On-Line Community Network on Social Capital M Mc Nally, M Bannon, J Greaney, A Hickey, M Mc Technology has been traditionally seen to be a cause of decline in social engagement and interaction, for example increased television viewing is associated with lower levels in Social Capital. However, it is now believed that on-line technology and CMC can be used to increase social capital. Technology can achieve this by removing the barriers of time and location, allowing communication over distance and by allowing asynchronous interaction.
