WLANPlus 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 CE devices and reduces total product costs.
2x3 MIMO – optimized cost/performance 2x3 MIMO architecture consisting of two chips supporting the dual band operation. Spatial diversity gain between a 2x2 MIMO configuration and a 2x3 MIMO configuration is 4 to 5dB, resulting in an increased 30% reach for home environments equivalent to an increase of ~80% in coverage area.
