3 Product Overview

The J20H085 802.11a/b/g/n 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 ,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.
