Metalink is a technological leader in 802.11n solutions. The second generation advanced WLANPlus is a high-throughput wireless LAN technology optimized for the networked home. Featuring best of breed MIMO technology, WLANPlus easily connects to computers, laptops, peripheral equipment and WiFi phones in the home environment at unmatched throughput and range.
Metalink is the first in the industry to offer 5Ghz band 802.11n chipsets. Metalink’s second generation chipsets leverage technological expertise to produce 2.4Ghz and dual band concurrent home networking solutions.
WLANPlus is compliant with 802.11n draft 2.0 standard as well as with legacy 802.11a/b/g devices and to 802.11h (radar detection), 802.11i (security) and 802.11e Quality of Service (QoS).
Key Advantages: · Superior Performance - Superior MIMO detector - Metalink's MIMO detector’s (slicer)
gain over traditional decoding can be as high as 5dBs, which
is equivalent to ~40% improvement in range, approximately
doubling the coverage area. - Advanced FEC (Forward Error Correction) scheme -
WLANPlus offers the use of LDPC (Low Density Parity Check)
as an optional FEC scheme, resulting in the addition of up to
3dB of SNR (Signal to Noise Ratio), which can be used to
transmit over greater distances and/or at higher bit rates.
This means that the range is effectively extended by 30% or
that it offers a 30% increase in speed over the range offered
by comparable products without such a feature. - Optimized solution for video applications - Metalink is the
best solution for contemporary latency-critical application
such as IPTV and gaming, which require UDP packets. Quality
video transfer requires minimal delay, constant throughput
and, most importantly, zero packet loss (because in UDP, a
lost packet cannot be restored).
Metalink’s solution is the optimal solution for wireless video
applications because it is capable of UDP transfers with zero
PER and minimal delay and at a constant throughput. - Low interference 5GHz band support - In addition to
superior performance in the 2.4GHz band, Metalink is a
pioneer and leader in 5GHz band. Through special RF design,
WLANPlus provides the best 5GHz band support in the
market. It does not interfere with microwave ovens, baby
monitors, cordless phones, Bluetooth devices or 11b/g
networks. In contrast to 2.4GHz band’s 3 channels, it doubles
the throughput via channel bonding using 2 out of the more
than 20 channels available. WLANPlus is compliant with CE
certification. - Dynamic Link Setup (DLS) - DLS saves on airtime, increases
network efficiency, and is well suited for home environment
architectures, where every CE device should be able to
communicate with any other CE in the household. This
technology allows a data stream to be sent from one station
to another without going through an access point, which
would require doubling the bandwidth. · Superior Quality of Service - EDCA plus Admission Control - WLANPlus offers a bandwidth
guarantee by supporting EDCA with optional Admission
Control (AC). - Fast Link Adaptation (FLA) - WLANPlus provides a dynamic
QoS mechanism that adapts the bit rate based on actual
packet-error rates. This feature ensures that the CE device’s
connection rate adapts rapidly and dynamically to
environmental shifts and changing Access Point distances. · Superior Architecture - Integrated MAC - WLANPlus includes full implementation of
an integrated MAC, dramatically reducing the required
processing power and memory allocation from the application
host processor. This simplifies integration with consumer
electronics devices and reduces total product costs. - 2 x 3 MIMO – optimized cost/performance 2 x 3 MIMO
architecture consisting of two chips supporting the dual band
operation. Spatial diversity gain between a 2 x 2 MIMO
configuration and a 2 x 3 MIMO configuration is 4 to 5dB,
resulting in an increased 30% reach for home environments
equivalent to an increase of ~80% in coverage area.
