4G phone service: T-Mobile supercharges 3G network to compete
Although we鈥檙e certainly not going to look at any increase in mobile broadband speeds as a negative, one thing to remember is that, technically, even the likes of 鈥檚 service and aren鈥檛 really 4G.
For want of a better term, their speeds only equate to 3G+. That means if you鈥檙e a company like without a real 4G rollout plan going into 2011, one way to catch up to the competition is not by building new 4G towers, but by supercharging the existing network to the utmost limits of existing throughput. And, in fact, that鈥檚 exactly what T-Mobile has up their sleeves: they鈥檙e currently working on charging their current 3G HSPA standard to make it as fast as 4G, reaching speeds of 650Mbps.
How鈥檚 T-Mobile doing it? They鈥檙e teaming up with Siemens to develop a new 3G antenna array that is similar to the MIMo tech used in WiFi routers. By having a single device picking up and broadcasting multiple frequencies on multiple antennas, they can fuse those different signals picking up different bandwidth pipes together for even faster throughput.
A pretty bold plan, indeed. Of course, if it works with 3G, it should work with 4G too. How fast could Verizon鈥檚 get if they tried the same multiple antenna approach?
