CHAPTER 1. MODULE OVERVIEW
The Foxconn WBSR12 wireless module contains the Realtek RTL8723BS-VD single chip
which is a highly integrated single-chip 802.11b/g/n Wireless LAN with SDIO interface and
integrated Bluetooth 2.1/3.0 /4.0 with UART interface. It combines a WALN MAC, a 1T1R
capable WLAN based-band, and RF in a single chip. The RTL8723BS provides a complete
solutionor for a high performance intergrated wireless LAN and Bluetooth device. The
integration provides good coordination and with sophisticated dynamic power control and
packet traffic arbitration to achieve good coexistence perofrmance between 802.11 and
Bluetooth.
The RTL8723BS-VD WLAN MAC supports 802.11e for multimedia application, 802.11i for
security, and 802.11 for enhanced MAC protocol efficiency. Using packet aggregation tech-
niques such as A-MPDU with BA and A-MSDU, protocol efficiency is significantly improved.
Power saving mechanisms such as Legacy Power Save, and U-APSD, reduce the wasted during
idle time, and compensate for the extra power required to transmit OFDM.
The RTL8723BS-VD Bluetooth controller complies with Bluetooth core v4.0, and support
dual mode (BR/EDR + AMP +Low Energy Controllers). It is compatible with previous versions
including v2.1 + EDR and v3.0 + HS. For BR/EDR, it can support scatternet topology up to four
active links in slave mode, and seven active links is master mode. For Low Energy, it supports
multiple states and allows eight active lins in master mode. Both BR/EDR and LE can operate
simultaneously.
