Brief
Single-chip IEEE 802.11b/g and single-stream 802.11n delivering
data rates of 150 Mbps and TCP throughput of 100 Mbps.
High level of integration on chip enables reduction of more than
33% in RBOM compared to 11G solutions.
Low component count and low PCB trace length enables ultra-
compact and 2-layer PCB design, delivering significant reduction
in PCB and housing costs.
Time-to-market is significantly reduced through stable Linux
VxWorks
drivers, and toolchains.
Unique Green Wi-Fi mode coupled with 65 nm CMOS design
results in significant reduction in power consumption under
typical usage scenarios.
The BCM5356 delivers the lowest cost and highest performance
wireless LAN router SoC integration for residential and small
office/home office (SOHO) markets.
