I would think that very limited markets will actually have 20 Mhz of spectrum available. Often times I get less than 2-3 Mbps on LTE on Verizon in some areas during the daytime. Even if that much spectrum was available, what about the backhaul? 150Mbps seems like a very rare case, is it really worth it?
Verizon AWS Thanks to the cable companies they have 20x20MHz AWS in like all markets. T-Mobile with MetroPCS will have 10x10MHz + 5x5 AWS MHz in most markets. In some markets They have 20x20 as well.
That is probably a lightly loaded cell so one user getting 150Mbps isn't likely (when was the last time you got 50Mbps+ on LTE?). User speeds are likely to double your speeds now - so 10-20Mbps.
The important thing with this is carrier aggregation, both intra-band and inter-band for max user speeds. It givens companies an incentive to use all the spectrum they own so they can be the "fastest" carrier in America.
Unless they actually meant "miilibits per second", heh.
I tend not to correct a layman using the wrong symbol, but these guys are supposed to know what they are doing, and using the wrong symbol just isn't right. How are our young people supposed to grow up literate when the engineers pull crap like this?
Great tech, good to see it in progress, but I have to be honest, I get a little skeptical about the quality of the work when I see mistakes like this.

Clearwire TDD - 40MHz+ wide channels possible.Verizon AWS Thanks to the cable companies they have 20x20MHz AWS in like all markets.

The idea is, as I pointed out in the Transceiver/Modem piece - http://www.anandtech.com/show/6541/the-state-of-qu... to do carrier aggregation of two 10 MHz LTE carriers and get to an equivalent 20 MHz carrier.That's essentially AT&T's plan, and a few other operators in the USA (eg their 700 MHz band 13 or 17 + band 4) 10+10 FDD.
