BL-M8197FH1 is a highly integrated WLAN Repeater module, it combines a 2T2R dual-band concurrent WLAN system, a high performance CPU system and a memory system. The module compatible IEEE802.11 a/b/g/n/ac standard and provides the highest PHY rate up to 300Mbps +866.7Mbps, offering feature-rich wireless connectivity and delivering reliable throughput over extended distance.


  • Operating Frequencies: 2.4~2.4835GHz and 5.15~5.85GHz

  • IEEE Standards: IEEE 802.11a/b/g/n/ac, PHY rate can reach up to 300Mbps+866.7Mbps

  • Supports 5MHz/10MHz narrow channels and excellent RF performance for 5G WLAN communication over longer distances

  • Customized low TX power and high-level RX capabilities are more suitable for 2.4G WLAN zero distance relay communication

  • High performance MIPS 24Kc CPU Core up to 1000MHz speed

  • 64Mb SPI NOR FLASH(Customization capacity up to 256 Mb)and 512Mb DDR2 Memory

  • Provides variety of practical peripheral interfaces

  • Connect to external dual band antenna through IPEX connectors

  • 5.0V single Power Supply

  • Optimized software and hardware design are more suitable for 2.4G and 5G dual-band WLAN relay transmission applications. For example, The UVA with BL-M8812CU2 or BL-M8822CS module can transmit 800Kbps video streams to a Smart Phone over long-distance of 3KM
