Wireless Internet refers to a network that enables you to access the internet without necessary using any cables. The medium used in wireless internet is airwaves or radio waves, through which data is transmitted from one device to another. Most people prefer wireless internet to cabled internet connections due to its advantages. Manufacturers too are always producing electronic and communication devices that can access wireless internet.
There are various ways of accessing wireless internet. The first is via satellite. This type of wireless internet communication is mostly by governments organizations such as the military, and other big cooperations. For you to access wireless internet via satellite, you need a dish/receiver which will be fixed permanently on the ground or a structure such as a mast or tall building. This receiver is then positioned at an angle corresponding with the international satellite station which orbits the earth. This wireless internet connection is faster in speed and more convenient, especially where remote areas are involved. However, it is a bit costly for small businesses and individuals to set up and run. It is also affected by rain and the connection signal can be lost if there is obstruction between the two devices.
The other is through wireless broadband. In this case, an office or a home can be connected to the internet through a wireless broadband modem. The antenna/receiver is mounted on a raised services, say a roof top. The antenna then picks the internet signal from the internet service provider (ISP), and relays it to a modem. The modem then connects to a router which distributes the internet to various available devices. There are a also portable modems in the market which can be used to deliver wireless internet. This type of wireless internet is relatively cheaper than satellite to set up and run. It can also allow a number of devices to be connected to the internet at the same, hence making it cost effective. Connection speeds here are fast enough. However, setup costs for this wireless internet may be incurred.
Broadband wireless internet can also be offered by mobile telephone companies. These companies use their existing network of base stations to give wireless internet connections to their customers alongside other telecommunications services. Cellular internet uses a set of rules called WAP (Wireless Application Protocol), which enables mobile phones to connect to the normal internet and allow access to various online services. Therefore for you access such services, your cellphone must be internet enabled. Extra charges other than the normal cellphone calling rates may apply, depending on the company offering the wireless internet service.
Compared to other types of internet access, wireless internet is more convenient due to its mobility. You can have wireless internet on your cellphone, laptop, pocket PC or tablet and still move around without worrying about jacking away any connected cables. Wireless internet is therefore recommended for people who are always on the move.
The one concern about wireless internet has been its connection speeds, which have been slower than those of cable internet. Previously, wireless internet has been offered on technologies such as GPRS and EDGE. They are now being replaced by better and faster wireless internet technologies such as 3G, 4G and WiMAX. This guarantees connection speeds which much those of cable, while still using wireless internet.
