3 Product Overview
The J20H081.00 802.11a/b/g/n/ac and BT3.0 module provides wireless modem
functionality utilizing direct sequence spread spectrum and OFDM/CCK technology. This
module is based on MTK MT7650U solution .It fully complies with IEEE 802.11n,IEEE
802.11 a/b/g and ,IEEE 802.11 ac standards,!Bluetooth v2.1+EDR,
v3.0 standard, offering feature-rich wireless connectivity at high standards, and delivering
reliable, cost-effective throughput from an extended distance. Optimized RF architecture
and baseband algorithms provide superb performance and low power consumption.
Intelligent MAC design deploys a high efficient DMA engine and hardware data processing
accelerators which offloads the host processor.
