Wireless Data Transmission 
With the ever increasing voice and data communication traffic the air waves are not as
they used to be few years ago.  Currently more and more people are depending on
wireless links due to its cost effectiveness.  Wireless Local Area Networks (WLANs) are among the more recent examples of such a dependability.

WLANS Worldwide
The worldwide market of WLANs is expected to rise from US$1.7 billion in 2002 to US$3.8 billion in 2006 according to Gartner Dataquest projections. So what is fueling this growth? WLANs continue to enjoy their greatest success in key vertical markets where the benefits of mobility and cable replacement make them an appealing alternatives to traditional LANs.

Image plays a role as well; many colleges and universities are actively deploying the technology partly because the concept of a ‘totally wireless campus has marketing appeal.

Perhaps the most interesting market for WLANs is targeted at mobile professionals who frequent airports, hotels, convention centers and other public places. Hotel lobbies and airport lounges are particularly appealing because the business model is compelling.

Difficult-to-Wire Environments
Historical or old buildings, asbestos installations and open area where wiring is difficult to deploy. 

Frequently Changing Environments
Retailers, manufacturers and those who frequently rearrange the workplace and change location.

Temporary LANs for Special Projects or Peak Time Usage
1-trade shows, exhibitions and construction sites where a temporary network will be practical. 2-retailers, airline and shipping companies need additional workstations during peak period. 3-auditors requiring workgroups at customer sites.

Access to Database for Mobile Workers
Doctors, nurses, retailers, accessing their database while being mobile in the hospital, retail store or office campus.

SOHO (Small Office and Home Office) Users
SOHO users need easy and quick installation of a small computer network.

High Security Connection
The secure wireless network can be installed quickly and provide flexibility.

Point-to-Point Broadband Communications
Dedicated private link over 20 Km line-of-sight can normally be achieved, high data rate with no user charge. 

Point-to-multipoint Data Network
One AP serves 60 end-user terminals, all relocatable.

Interbuilding and Intrabuilding Private Wireless Network
Each terminal has a unique IP address ID according to its equipment MAC address, easy for control, monitoring and security. 

Wireless Internet Connectivity
Using MAC address identification, the system provides bandwidth control, firewall, billing and security. No intruders. 

Remote Surveillance
from single channel to multi channel, 30 frames/sec, real time observation and compressed picture record storages up to a week. 

Gas and Power Meter Utility Reading
Apartment complex remote reading of all utilities, warehouse and
factory applications as well. 

Hotspots
These are small enclosures such as cafeterias, lounges, restaurants, hotel lobbies and even college and school campuses equipped with a wireless  facility for INTERNET access. Visitors may log on to the internet on their laptop computers thereby  making better use of their time while visiting or waiting. Users may use their own WLAN cards or may hire them at these places.
