Bluetooth Design Requirements
This section describes the design requirements needed to interface an Intel 802.11 wireless LAN
device (Intel
Wireless Coexistence System (WCS) specification. Other requirements for supporting Intel
PRO/Wireless and Bluetooth features are also addressed. The following topics are covered in this
section:

1. PCB interface requirements

2. DC power requirements for Bluetooth

3. Selective Suspend support requirements
4. Wake on Bluetooth support requirements
5. RF Disable support requirements for Intel PRO/Wireless and Bluetooth Devices
12.1. PCB Interface Requirements
Two PCB traces shall be used to carry channel number and clock signals between Bluetooth and Intel
PRO/Wireless 2100. Although these traces do not need to match any length, width or impedance
constraints a typical width of 5 mils and spacing of 5 mils is recommended. Pin # 43 of the mPCI
connector needs to be routed to the Channel_Data signal of the Bluetooth module. Pin # 36 of the mPCI
connector needs to be routed to the Channel_Clock signal of the Bluetooth module. The Channel_Data
and Channel_Clock pins on the Bluetooth module are vendor specific. Please refer to the corresponding
Bluetooth module vendor for this information. The traces between Intel PRO/Wireless 2100 and
Bluetooth are a point-to-point connection and do not require any intervening components.

12.2. DC Power Requirements for Bluetooth
Voltage levels to power Bluetooth modules are vendor specific. Typical voltage requirement to power
Bluetooth module is 3.3Vwith 2% tolerance. This source may be derived from any power rail
available on the platform capable of providing the Bluetooth module power requirements. Please note
