20 GIG DEMO 230The meter reads 20 gigabits.  Jack Zhu had just said, "You have to see this," and pulled me over. It was the first demo of Huawei's four port bonded G.mgfast. 

Two boxes perhaps five feet apart, were connected by four lines of cat 6 cable. Each line carried 5 gigabits of prestandard G.mgfast.  The total is 20 gigs, They expect that speed to go 30 meters. They are finding good performance out to 100 meters.

How G.mgfast Reaches Hugh Speeds

.mg uses more spectrum. VDSL uses up to 35 Mhz. uses 106 MHz, going to 212. G.mgfast is 424 MHz today with plans for 848  MHz.

Analyst Teresa Mastrangelo wondered how Huawei met the processing demand. One answer was just 5 meters away. HiSilcon was showing a network processor chipset running at a terabit.  

Teresa also wondered what the speeds will be on ordinary Cat 5 telephone wires. They estimate it will be about 90%

Teresa also asked when products would be ready. Guesses are around 2020. The technology is close; Huawei and Nokia have impressive gear. If customers are ready to buy, the companies will bring plans forward.
