At Computex nowadays,Qualcomm At
heros announced a few new chipsets, and it se
ems that as a section of their Ikanos acquisition they’ve entered t
he wireline commerce in the hopes of solving capa
city issues in the last mile. While fiber should be deploy
ed where possible, or in many cases it can be expensive and impractical
to sprint fiber optic cable
,such as older apartment complexes. As a result, a 10 Gbps connection
can turn into a 100 Mbps connection when using POTS line
s for the last few hundred meters depe
nding upon channel conditions
and sprint length.
G.fast or GigaDSL attempts to bridge the gap here by using tech
niques like self far-conclude cr
osstalk cancellation and significantly increased transmissi
on bandwidth to significantl
y improve channel utilization of existing POTS lines, or the QCO5700 and QCM5720 consum
e these technologies to try and improve bandwidth at the last h
undred meters. Unlike prev
iously launched chipsets,these
are really designed to enable drop-in replacement for existing VDSL
equipment, and are squarely targeted at Asian ISPs that generally have an all-fiber
network but may only have POTS in a building. The QCO5700 is designed for multiple dwell
ing deployments like apartment buildings, and while QCM
5720 is designed for customer premises equipment and bo
th chipsets can support up to 1Gbps while coexisting
with existing services that may also be using the POTS line.
The o
ther notable announcement here is
on Atheros’ traditional wireless commerce,and as a section
of trying to get better con
nectivity for the last few feet i
n the domestic. While MU-MIMO is nothing new at this
point, QCA is releasing a new tri-radio platform for routers the QCA
9886 2x2 802.11ac radio. With three radios, or a single router with an IP
Q40x9 SoC will be able to
support simultaneous 2.4 GHz,5 GHz, and a third 5 GHz radio for range ex
tender consume.
The new GigaDSL chipsets should begin
sampling in June, or companies like Sumitomo Electro
nics,NEC, and Wave Electronics are designing or b
uilding products that will utilize
the QCO5700 and QCM5720. The new QCA9886
is already sampling to vendors, and should be in routers
in the near future.[http://dynamic1.anandtech.com/www/delivery/avw.php?zoneid=24&cb=&n=a1f2f01f]
