2 Product Overview
The J20H084.00 802.11a/b/g/n/ac 2X2 and BT4.0+LE module provides wireless modem
functionality utilizing direct sequence spread spectrum and OFDM/CCK technology. This
module is based on MTK MT7662U solution .It fully complies with IEEE 802.11n,IEEE
802.11 a/b/g and ,IEEE 802.11 ac standards,
Bluetooth v2.1+EDR,
V4.0 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.
