Re: Bye Fiber

I think the cited speeds are per cell tower, and it gets divided up by the number of active users. FTTH will still be plenty useful...

Re: Bye Fiber

Very true...the article doesn't state how much spectrum capacity is required for 280Mbps. Current CDMA2000 technologies require 1.25MHz channels (1up/1down).
quote:
UMB would use MIMO and SDMA in order to provide greater capacity and coverage, CDG said
According to CDG this could mean using 20MHz of spectrum (paired) for 280Mbps.
»www.cdg.org/technology/3g_umb.asp
# Flexible spectrum allocations

* Scalable, non-contiguous and dynamic channel (bandwidth) allocations
* Support for bandwidth allocations up to 20 MHz in 1.25 MHz blocks
