1.6 Features
The board must provide the following features:
WLAN:
TX and RX low-density parity check (LDPC) support for improved range and power
efficiency.
Single-stream spatial multiplexing up to 433.3 Mbps data rate.
Supports 1 antenna with one for WLAN & Bluetooth shared port
20, 40, 80 MHz channels with optional SGI (256 QAM modulation)
Supports standard SDIO v3.0 HOST interfaces.
Bluetooth:
Give dual mode BT connectivity (Classic & Low Energy)
Complies with Bluetooth Core Specification Version 5.0 with provisions for supporting
future, With Bluetooth Class2 transmitter operation.
Supports extended synchronous connections (eSCO), for enhanced voice quality by
allowing for retransmission of dropped packets
Adaptive frequency hopping (AFH) for reducing radio frequency interference.
Interface to the motherboard with UART and PCM, UART up to 4Mbps.
Integrate PCB antenna, which will be shared Bluetooth and WLAN
2 General Requirements
2.1 Standards
2.1.1
BT related certification
On the Bluetooth.org website, the existing certifications of BT solutions are listed.
The certification strategy will be as
follows:
Make a certification for the board, with embedded low part of the BT stack, and antenna
Make BTWDB a module certification, where we can take benefit of the module
certification
