As the world is going from Wires to Wireless, The technology and speeds of wireless communication is also going leaps and bounds. The wired network often goes too congested and offers a hindrance to mobility needs of the users.
With wired Networks, although security features and speeds are yet unmatchable by the wired networks, yet the inability to being flexible is what causes the wireless mediums to gain more public attention.
There are many sorts of wireless networks that make that data communication possible both over long range and small range. All of these networks operate over different frequencies and a channel Gap between different frequencies avoids the collision between them impossible.
The major types and functions of major wireless mediums are described as follows.
Microwave Communication is the most common wireless communication medium and is spread widely across the world. Most of the wireless access points and wireless devices work on microwave communication.
This sort of communication works in Mega Hertz frequencies and offer speeds of 2 Mbps to 20 Mbps. The operating range spans to 30 kilometers which can be extended with the help of wireless regenerators.
This communication medium is not only cost effective but widely used as well in not only computers but cellular communication as well.
Bluetooth is another wireless communication medium operating over short distances. It has a normal range of 11 – 30 meters between two connecting devices and have spends between 10 kbps to 1.2 mbps. Bluetooth is very useful in indoor communication of small area networks.
A Bluetooth network is sometimes also called a Home area Network. This kind of network is cost effective as well. Although it can cross the walls yet it can not obtain high speeds and is disturbed by various factors.
Infrared is one of the most primitive forms of wireless communication. The biggest draw back with infrared communication is the line of sight problem. At the point where Microwave and Bluetooth are scattered in circles around the base stations, Infrared Networks need to have the two devices in line with each other with an angle of +_15 degrees. Different Wireless devices can be joined together through a common access point and scattered across different devices.
Automatic discovery and mobility are the most important appealing features of Wireless Networks. You can stay connected while on the go for over. The inter access point device handling is possible making the wireless network more easy to use and flexible.
Satellite communication is also covered in Wireless communication but less applicable under this category because it not only operates over very long distances but their frequency ranges differ widely as well.
With the help of wireless networks, it is possible now to send and receive data and stay connected at all times even during travel. Wireless communication is changing the look of data communication for ever and it is going at a high pace.
