Has Home Networking Got A Future?
It always struck me that WiFi was the route to home networking, then Marvell tells wireline is the way forward – at least until Marvell’s managed to put wireless on the same IC as its wireline transceiver which will take a couple of years.
Home networking has always been a dodgy area. For decades Echelon pursued what seemed a crazy strategy of networking everything from light bulbs to curtains.
While the different plugs and sockets on TVs and PCs have made it tricky to connect up the two most obvious candidates for home networking.
Now, however, home networking has a market driver, Marvell’s Ramon Garcia tells me: “The main driver for home networking is IPTV. All the major telcos are supplying it including BT Vision, China Telecom, Telefonica, Verizon, AT&T and Deutsch Telekom. Most of the IPTV providers are relying on powerline.”
Marvell has just brought out a transceiver chip-set which can deliver data over powerline at 200Mbit/sec and also works on coax and twisted pair phone lines.
It’s competing with Marvell’s own Avastar a MIMO WiFi chip-set which offers data rates ‘up to 300Mbit/sec.
It’s taken an awful long time, but maybe home networking has a future.Tags: chip set, decades, light bulbs, telecom 2c, twisted pair
