Wireless network is a term most often used to describe telecommunications network with nodes that are interconnected without the use of wires although technically a wireless network is any network that is wireless. Wireless telecommunications networks may also be referred to as computer networks which are a type of telecommunications network.
Normally an information transmission system which uses electromagnetic waves (radio waves for example) to carry information is installed for use with wireless telecommunications networks. When looking at a wireless network diagram this usually describes the physical level of the network
A wireless LAN (local area network) is a specific type of wireless network. Like other wireless devices, wireless LANs use radio waves to transmit data packets to and from computers on the network instead of wires.
GSM (Global System for Mobile Communication) networks are split into three major subsystems: the switching system, the base station system, and the operation & support system. Most cellular services use GSM to operate their cell phone networks. GSM works by connecting the cell phone to the base system station which in turn connects to the operations and support station. Then is connects to the switching station and the call is transferred to its final destination.
As long ago as World War II, wireless networks were making a significant impact on the world. Wireless networks were used to transmit information overseas and behind enemy lines as a method of quick and reliable communication. Wireless technology continued to evolve over the next several decades until it exploded in recent years most notably in the cellular phone industry.
One benefit of wireless networks we can all appreciate is the elimination of the need for cords and cables that get all tangled up and hard to unravel. The trade off is that wireless communication can be more easily blocked or interfered with than when wires and cables are used to transmit data.
Another possible issue with wireless networks is compatibility. Components manufactured to different specifications may not work well together kind of like a Chevrolet engine isn’t likely to be compatible with a Mercedes Benz. A car is not a car in this case and the same holds true for wireless network components. Compatibility issues in wireless networks can be largely avoided by using components made by the same manufacturer.
In terms of Internet connections, wireless networks are usually a bit slower than networks directly connected with an Ethernet cable. In many cases, the difference in speed is negligible and may only be noticed when streaming video files are downloading large files. Wireless technology has developed to the point where it is quite simple and inexpensive to have a wireless network up & running if you’ll just follow the directions shown on the wireless network diagram.
