Ready for wireless?

The wireless LAN market has seen a lot of growth worldwide recently, thanks to the wide

support it’s been receiving from the industry. Whether it’s the semiconductor

manufacturers, who make chips for wireless devices, or the standardization bodies, who

have laid out the guidelines for making wireless devices interoperable, they’ve all

contributed extensively to its development. Wireless LANs have recently started becoming

available in India, and will hopefully be as successful as they’ve been elsewhere.

In this story, we look at the applications of wireless LAN implementations across the

world, and the resulting benefits. We also look at how feasible it is to implement from

the cost point of view, as well as understand the government regulations and licenses

involved. We also take a roundup of the types of devices that are currently available, and

which ones to expect in the future.

There are a lot of wireless standards floating around, and the most feasible for

wireless LANs is the IEEE 802.11b, which allows a throughput of up to 11 Mbps in the 2.4

GHz band. Other standards like Bluetooth, Infrared are being looked at for wireless at

home and personal use, and the concept is known as WPANs (Wireless Personal Area

Networks). It’s important for these various standards to be interoperable with each

other if new applications for wireless are to be realized.
