Lynnwood, WA | Bye Fiber Fiber to the home is kind of useless if you can do 280Mbps over the air. | |

San Ramon, CA | Re: Bye Fiber Yep, I guess thats why AT&T isn't putting all of their eggs into the fibre.
All of these crybabies on here don't seem to understand wireless is the future. | |

Rowley, MA | 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 | |
