212 from Sckipio 200Rami Verbin of Sckipio has no doubts: Doubling the frequency range will double speeds from today's 500-800 megabits. Soon, perhaps in 2018, apartment buildings will get 1200-1500 megabits from either fiber to the basement or wireless to the rooftop.  Close in distribution points, like those announced by Australia's NBN, will also see those speeds.  

Thousands of homes can now get 500-800 megabits with first generation chips, using 106 GHz. The field results confirm the models used by Rami and the other members of the standards committee. BT's Trevor Linney says the model has proven "pretty much spot on." 

At 50 meters - 8-10 stories in most buildings - 1400 gigabits is expected. A gigabit should reach 80-90 meters. After about 150 meters, the extra spectrum yield almost no improvement. High frequencies don't travel very far over copper. Chart from Sckipio at right.)

The standards committee is already working on using 424 GHz and even 848 GHz.

212 GHz and cDTA are soon shipping from Adtran. True gigabit is here. Sales takeoff is almost in sight, probably Q1 2018.
Australia confirms 1M, AT&T is ready to ramp, DT finally is moving. Omantel and Telkom South Africa are now on the map. Almost all telcos are now choosing for large buildings when they don't go FTTH. MNet Cologne and Chunghwa Taiwan have changed from fiber all the way to in the basement.

212 MHz and cDTA Are Ready: Adtran

Adtran Chosen for Australia nbn Fiber to the curb.

nbn looking to a million lines. This one is big. Adtran is on a roll, with DT & AT&T also looking good for 2018.
