Lantiq Sampling 3x3 MIMO For Faster VDSL Gateways
Supporting existing VDSL chip, extending bonding. Imran Hajimusa of Lantiq had a great demo of 4 HD channels streaming over WiFi a while back. They are now sampling and about to ship this improved WiFi, 3x3 MIMO 802.11n, a technology they purchased from Metalink. They've also upgraded their bonding capacity, which now can use VDSL profiles 17 & 30 for two line download speeds of 150-200 megabits over short loops. Their previous VDSL bonding could only do up to profile 8, for speeds under 100 megabits.
Telcos are screaming for reliable TV grade WiFi. I've heard claims as many as 50% of service calls are due to WiFi rather than DSL problems. When you carry you iPad to the bedroom upstairs, you don't want to lose the football game stream. Dirk Wieberneit of Lantiq reports raw WiFi speeds normally are fine, but don't often reach far enough into the home. The 3 antennas of their MIMO chips allow further reach with beamforming
Higher connection speeds require more processing power in the gateway. VTel discovered, for example, that nearly all home "gigabit" routers peaked out at about 300 meg. Since they are delivering a true gigabit. that wasn't acceptable. http://bit.ly/10ukHRp iPads and second multiple HD TVs around the house increase the local bandwidth needs.
Swisscom, using the related 4x4 MIMO, rarely has problems with wireless HD TV around the home. Hajimusa believed that in real environments the four antennas of 4x4 made little difference. The folks at Quantenna, shipping 4x4, disagree. I don't have results from the fields by carriers on the effectiveness of 3x3 MIMO and so can't judge.
Hajimusa is now at NXP as new management has taken over at Lantiq.

XWAY™ VRX300 Family – Ultra-Fast Access Network Speeds With 200 Mbps Bonding and up to 150 Mbps Vectoring Paired With Industry-Leading Integration and Flexibility for In-home Networking
VDSL2-ready CPE system shipments are forecast by IHS iSuppli to grow from about 22 million in 2012 to more than 57 million in 2016.
While market Researchers predict strong growth rates for VDSL, Lantiq already today delivers leading edge VDSL2 systems. The Lantiq VRX300 Chip Set Family drives down system costs while improving access and in-home network performance. With the VRX300 Chipset, we are again raising the bar to help equipment providers meet ever tougher requirements and reinforce the competitive position of carriers.Monday, 13 May 2013 11:49
