Do we ever have Mobile WiMAX in India? I think it is reasonable to say that , by the end of 2010 we will have at least top 10 markets in India covered by Mobile WiMAX with minimum of 2 operators. This is really a big push for wimax community and broadband in country. The [...]
Continue Reading →By BP Tiwari , www.beyond4g.org Wireless community has stated numerous times about the importance of 700 MHz band which is considered “beachfront property”, implying that this band is very valuable. But why is it valuable? The simple rationale most often cited is that the 700 MHz band has better propagation characteristics. Smaller cells at 2.6GHz [...]

Beceem vice president of business development Lars Johnsson clarified that “Beceem isn’t taking the much bigger LTE chipset market head on—at [...]
Continue Reading →BY : BP Tiwari The majority of the terminals that we have in current mobile wimax networks are 1 Tx in uplink and 2Rx in Downlink. The advantage of having two receive antennas in downlink allows use of advanced antenna configuration like STBC(space time block codes) and SM (spatial multiplexing ) to achieve higher spectral [...]
Continue Reading →By : BP Tiwari I have been observing emergence of new 4G technologies for last couple of years and one of the most talked multi antenna concepts is beamforming. BF is one of the much awaited technologies that helps operators to increase capacity in network and also helps in overall network quality by reducing interference [...]
