Wireless communication has become a part of daily life in the 21st century, but many people are still unaware of what a wireless communication system is and how it works. This article from POSMarket.com.au explains the ins-and-outs of wireless communication.

A wireless system basically consists of an access hub wired to a computer system, or the Ethernet, that transmits data through the air in radio wave form. Other communication devices then receive these transmissions and can also communicate back and forth with the hub. To this end, wireless communication systems can act like any wired network with the main difference found in the mode of transmission, i.e. radio waves rather than transmission cables.

Since there are no cables with wireless communication systems, workers do not have to worry about pulling devices on the other end of a cable or tripping over cables as they move around. The communication allows them to move through corridors checking inventory, or accessing files to assist customers from any location within range of the access hub.

The normal range of wireless devices is about 30 to 40 metres in an open air environment; however this can vary depending on various types of interference that might exist in the workplace. such as lift wells.

Some wireless networks come equipped with software applications that allow users to access databases for tasks such as checking stock. Some systems also allow the user to communicate with printers or other devices.

One of the original wireless systems is the Telnet utility, which at one point was also widely used in communication with servers over the Internet. The Telnet device allows users to view what is happening as a software application executes on a server.

Microsoft Windows systems also offer wireless connectivity using personal digital assistants (PDAs) to access databases like Microsoft Excel and Microsoft Access. Another option is to use a simple "flat file" system, which stores data in a portable text file that can be read by most types of applications.
