Scope
This document describes the hardware architecture for the wireless mini-PCI module MWL-41G1 and
its software specifications.
1. Introduction
This document is to specify the product requirements for
MWL-41GB1,
802.11g compliant mini-PCI
module based on Intersil Prism Frisbee and Bluetooth 1.1 Enable USB interface based on MBT4101M
Class 2 CSR based module.
This Bluetooth USB module (MBT4101M) is used to transmit/receive messages to/from other
Bluetooth devices. Based on Bluetooth connection, the messages can be directed at a specific device, or
can be broadcasted to all devices.
The design of the Bluetooth module will closely adapt the Bluetooth module (MBT4101). That is
connected to the host processor via a Bluetooth HCI link. As an effort to the interface connection to the
whole notebook systems, it can be directly soldered on the Notebook motherboard and routed to the
interface of the main board in the notebook systems.
This Bluetooth module is Bluetooth BQB qualified, power level of the class 2/3 and consists of either a
connector connecting to the external high gain antenna, or a on-board chip antenna.
IEEE802.11g mini PCI :
Following standard 32-bit PCI standard, plus Microsoft Windows compliant device driver and
installation utility, this product is an ideal for notebook computer system integration. Built-in security
mechanism includes WEP 64/128, AES engine and WPA. Hardware-based WEP provides good
performance and secure communications.

Bluetooth USB module:
Because Bluetooth enable products provide much more flexible applications than Wireless Lan
did.Next generation design of the Laptop mini-PCI would be possible to combine Bluetooth enable
function .. The benefit it would bring is mechanical design flexibility. Design team would not worry
about what BT daughter card dimension is, just because there is no industrial mechanical standard for
BT module.
Bluetooth and Wlireless Lan Coesostence(AFH-Adaptive Frequeny Hopping)
Adaptive Frequency Hopping goes a long way to solving the Bluetooth and Wi-Fi co-existence problem.
To deliver simultaneous operation of Bluetooth and Wi-Fi wireless technologies in PCs, CSR and
Intersil has developed Coexistence Technology, a unique collaborative real-time communications
interface at the MAC layer that is transparent to the user. Data can be transmitted without interference
while optimizing throughput, range and responsiveness. This enables Bluetooth applications such as
mouse, keyboard, printing, file transfer and portable device synchronization to run at the same time the
user is connected to the network over Wi-Fi.
