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.

The wireless LAN is compliant to IEEE 802.11n,IEEE 802.11 a/b/g and IEEE 802.11 ac

standards.
