Wireless technology has now permeated the computing landscape at all spatial scales: Bluetooth for local cable replacement within 10 metres or so; 802.11b for LAN and Internet access up to 30m from an access point or gateway; and GPRS for remote access to corporate networks and the Internet wherever you can get a signal. Data rates range from up to 56Kbps for GPRS to a maximum of 11Mbps for 802.11b, with Bluetooth slotting in at just under 1Mbps. Companies with flexible, mobile workforces will be interested in all of these technologies, but GPRS, with the potential to wirelessly connect remote workers pretty much continuously, is likely to top the list.
