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.

Coexistence:
Adaptive hopping Bluetooth devices will move into that mode based on one or more of several possible interference-detection mechanisms. Among the technical approaches: - The Bluetooth device gradually adapts its normal operation hop pattern based on observed packet loss. - The Bluetooth device detects and assesses received signal strength across its wireless environment before commencing operation.
5
Company Confidential
- The Bluetooth device transmits a "test" pattern of packets across the entire spectrum, observes the ratio of lost packets across available channels and locates its adapted piconet in the least active or interference-prone channel. - If the Bluetooth device is co-located with a Wi-Fi device and can receive the Wi-Fi passband location from the Wi-Fi device, it simply avoids operating within the Wi-Fi passband.

Protocol and PHY support are implemented in firmware to provide for custom WLAN solutions. Firmware implements the full IEEE 802.11 Wireless LAN MAC protocol. It supports BSS and IBSS operation under DCF, and operation under the optional Point Coordination Function (PCF). Low-level protocol functions such as RTS/CTS generation and acknowledgment, fragmentation and defragmentation, and automatic beacon monitoring are handled without host intervention. Active scanning is performed autonomously once initiated by host command. Host interface command and status handshakes allow concurrent operations from multi-threaded I/O drivers. Orthogonal Frequency Division Multiplex (OFDM) combined with BPSK through 64 QAM modulation of the individual carriers and a variety of convolutional coding rates provides 8 selectable data rates. Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling capability along with Complementary Code Keying provide 4 selectable data rates or DSSS mode. Built-in flexibility allows the ISL3880 to be configured for a range of applications. The MAC is based on the ARM 946E processor core that offers a wide variety of code development support tools. The ISL3880 is housed in a thin plastic BGA package suitable for CardBus or Mini-PCI circuit card applications.
