F1: Will IEEE802.11b WLAN Adapter work in the environment where Bluetooth network is employed?

Yes, IEEE802.11b WLAN Adapter can coexist with Bluetooth envi- ronment.

F2: How far is the working range of IEEE802.11b WLAN Adapter?

It depends on the data transmission rate and the condition of the environments. The higher the data rate, the smaller the range it could cover. At 11 Mbps, the adapter can go up to 300 meter in an outdoor environment; however, in an indoor environment, it can only go up to 100 meter. Because of the ceilings, higher RF interference, interior walls and reflected signals, indoor range is usually shorter than outdoor range.

F3: How does the data transmission rate work?

IEEE802.11b WLAN Adapter allows you to choose one of the six data rate options: Fixed 1Mbps, Fixed 2Mbps, Fixed 5.5Mbps, Fixed 11 Mbps, Auto Select 1 or 2 Mbps, and Fully Auto.

The farther the distance between two communicating devices, the slower the data rate should be used. Basically, with slower data rate, the data delivery will be more reliable. If you don’t know which data rate should be used, simply choose “Fully Auto”, and the data rate will automatically step down from 11 Mbps, 5.5 Mbps, 2 Mbps, to 1 Mbps if you move farther your Toshiba Pocket PC e800/e805 away from the Access Point or other connected mobile device.
