– Aims at Millions of MDU Residences Worldwide
– Speeds up to 1 Gbps via Roof-top Antenna, Fiber to a Wiring Closet and Existing Copper Wires to Each Residence
A year and a half ago in March 2015 we accurately reported this account of the system that AT&T is now trialing in Minneapolis. In light of what AT&T is considering deploying widely, perhaps nationwide, it’s worth repeating because it may show what is to come because any cellco can build national broadband networks that serve MDUs. All that is needed are the fiber networks, which most cellco already have installed to connect to their cellular towers. Only one thing has changed: G.fast can now be deployed over coax in addition to copper phone wires.
Until now, G.fast has depended on telcos deploying fiber to within a few hundred yards of the residence. That is not always possible or affordable. Now broadband service providers can use wireless antennae within about 2.5 miles of an MDU, thanks to a partnership between Siklu, a wireless technology company, and Sckipio, a maker of G.fast chips. Speeds for residences can be up to 1 Gbps.
The network architecture:
– The antenna, typically located on the roof of a multi-story MDU, must be within line-of-sight of another like-antenna
– Fiber is used from the antenna to a wiring closet, typically located in the basement of an MDU
– Each G.fast distribution point in the wiring closet can use the building’s existing copper phone wires [now it can also be coax] to connect to up to 16 individual residences. Inside the MDU’s residences or offices, a G.fast modem or gateway is used to connect the Internet to mobile and stationary devices within the home or office.
The biggest benefits:
– No street digging/trenching is required, which saves time and money plus solves a problem with streets that are old and are in many places considered “antique.”
– The time-to-market for a 1 Gbps per residence network can be measured in months, not in years and the costs in millions, not billions.
– The 60-80 MHz spectrum that’s used costs much less than comparable cellular frequencies.
