Wireless world congress
This year one of the main actors has been the content producers and internet companies. Probably operators trust them a lot to boost their 3G networks. Another interesting point is the strong irruption of Chinese manufacturers, while other big players have switched part of their business to other activities more related to IT solutions providers. For those readers that are Spanish speakers, you can check the Vodafone blog for this Congress with some interesting topics. Apart from the convergence happening in this world, what would you expect for the future of wireless communications?

Squeezing the spectrum
UWB uses a very large bandwidth (more than 500 Mhz, imagine commercial UMTS mobile communications use carriers of 5Mhz…). And the more bandwidth tat is used, the more is the throughput. Although this is some kind of tricky because they have to use very high frequencies, and the range is very low Taking into account Shannon limit for the wireless channel, that states that the highest the bandwidth, the lower the signal to noise ratio required for a certain throughput. Also the emission levels permitted are relatively small. Therefore its main use will be for personal area networks.

Be an owner of the web
It works essentially with a Viewbar that is added to the bottom of your browser and allows you to get the benefit from the money generated by your searches, ads, and anti-fraud and other software utilities.

It is an original idea, attracting people with revenue, so it seems a nice move...
