What is Wireless Communication?

Wireless communication is information transferred over a distance without the use of cables or wires. This may be one-way communication systems such as television or radio broadcasting, or two way communication systems such as machine-to-machine (M2M).

Wireless communication can be via;

• Radio frequency
• Microwave (i.e. long-range and line-of-sight via antennas or short range communications)
• GSM
• GPRS
• 3G/HSDPA
• GPS
• ZigBee

Applications involve point-to-point, point-to-multipoint, cellular networks and all other wireless network communications.

Point-to-Point Communication

A point-to-point link is a communication medium with two endpoints. Data can be transferred from both computers at either end. The connection between the computer and the communication medium (GSM/GPRS Modem or GSM/GPRS Router) is generally through a RS-232 interface but Ethernet ports are also used.

Point-to-Multipoint Communication

A point-to-multipoint link is the communication between a computer and a central host where connections can be made from various end-points at different locations. Data can be transferred from the computer via the central host over wireless networks such as GSM, GPRS, 3G/HSDPA etc.

Cellular Networks

A cellular network is a radio network made up of a number of cells, each served by at least one fixed-location transceiver. The cells can join together to provide radio coverage over a wide geographic area. This enables portable transceivers such as mobile phones to communicate with each other.

Wireless Networks

A wireless network refers to any type of computer or machine-to-machine (M2M) link communicating without the need of cables or wires. This is commonly associated with telecommunication networks that the interconnections between nodes are implemented wirelessly.
