company confidential 4 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 mechani cal design flexibility. design team would not worry about what bt daughter card dimension is, just becau se there is no industrial mechanical standard for bt module. bluetooth and wlireless lan coesoste nce(afh-adaptive frequeny hopping) adaptive frequency hopping goes a l ong 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 a nd responsiveness. this enables bl uetooth applications such as mouse, keyboard, printing, file tran sfer and portable device synchroniza tion to run at the same time the user is connected to th e network over wi-fi. 1.1 product features wlan ieee802.11g ? compatible with ieee 802.11g high rate standard to provide wireless sp eeds of 54mbps data rate with ofdm modulation. ? backward compatible with ieee 802.11b high rate standard to provide wireless speeds of 11mbps data rate with cck modulation. ? dynamic date rate scaling at 54, 48, 36, 24, 18, 12, 9 mbps in ofdm mode ? dynamic date rate scaling at 11, 5.5 mbps in cck mode;2 and 1mbps in dqpsk and dbpsk mode. ? 32-bit mini-pci interface, type 3b ? maximum reliability, throughput an d connectivity with automatic fallback, auto-switch between ofdm and cck. ? supports wireless data encryption with 128- bit wep and wpa standard for security ? reserved on-board dual hirose rf connector for antenna extension
company confidential 5 ? drivers support windows 98se, 2000, me, xp ? driver support for embe dded rtos like uclinux ? simple user setup & diagnostics utilities ? type approval compliant with fcc part 15.247 for us, en 300-328 for europe, and rcr std- 33a and arib std-t66 for japan bluetooth ? csr bc02 single chip solution ? bluetooth specification 1.1 compliant ? pico-net support ? support up to 7 slaves ? wlan ieee802.11g coexist with bluetooth specifications 5company confidential ? class 2 transmitter power 0 dbm ? excellent receiver sensitivity ?80 dbm ? up to 30 meters peer-to-peer range with external antenna ? provide uart, pcm, usb interface ? full bluetooth rate uart: with programmabl e baud rate up to 921.6 kbps and a 128-byte tx and rx fifo. ? pcm codec interface ? on-module usb transceiver conforms to fu ll-speed 12 mbps speed of usb spec.1.1 ? on-module flash containing bluetooth software stack. ? dc supply from 5 v ? low current consumption 60 ma @hv5 ? four low power mode: park, sniff, hold and sleep. ? small size: 22 mm * 14 mm * 3.0 mm 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 a nd assesses received signa l strength across its wireless environment before commencing operation.
company confidential 6 - the bluetooth device transmits a "test" pattern of packets across the entire spectrum, observes the ratio of lost packets across availa ble channels and locates its adapte d 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.
