2.5G and 3G networks are currently
being implemented and will greatly enhance the transfer
rates between devices in the next few years.
-
The 802 series of standards
such as 802.11a and 802.11b specifications are rectified
by IEEE for wireless LAN (wLAN) for use in a business complex,
office building, warehouse, exhibition hall, temporary project
office, or any other business setting.
-
The effective operating
radius and number of concurrent user support ranges from
50 to 90 meters but can be extended by using access points.
-
Higher bandwidth
means more power is required. This is bad news for battery-powered
devices such as notebooks, laptops and PDAs. Technology
like Intel's Centino addresses the battery power utilization.
-
802
technology is suited for organisations which uses interactive
applications in a local area network (LAN) environment.
-
Bluetooth
is similar to 802 technologies but operates at a lower
transfer rate between 720Kbps to 1Mbps. Its range is also
limited to approximately 10 meters.
-
Bluetooth
is well suited for conducting quick data transfers between
devices such as PCs, cell phones, personal digital assistants
(PDA), and printers.
