The Phenomenal Advances in Wireless Communication

Thursday, November 8th, 2012

Long ago people used homing pigeons and human messengers to communicate with each other, but early eighteenth century marked the change in the communication systems when renowned scientists like Marconi and Maxwell developed systems that could transfer encrypted electric signals via wires. This was the time when Electric Telegraphs, long distance electric telegraphs, and electric telephones got popular.

The need and desire for efficient wireless communication has always been there; medieval men used to shout at each other from far away hilltops, then there were Chinese fire signals and American smoke war signals. The inspiration has been there.

It was not untilWireless Convenience the early nineteenth century that the first wireless signal was successfully sent. The famous scientists pioneering in the wireless communication systems were Faraday and Maxwell who discovered and used the fact that electromagnetic waves could travel in free space at a speed which was near to the speed of light. This paved way for the wireless communication system we have today.

Wireless radio communication was widely used in world wars for military communications. Wireless phones idea was incepted in America in 1940 and by 1980, these new innovative devices started conquering the entire world.

As wired communication evolved so did the wireless one. Local area networks and wide area networks began widely used via dial ups, cables and DSL systems. The wireless networks use wireless distribution methods which connect users to the internet through an access point. Different types of wireless networks include WLan, WPan and WWan.

Wireless local areaWiFi Router network or WLan connects a small amount of users within one premise without using an access point. This type of network is commonly used in universities, government buildings and hospitals. However, WLan restricts accessibility to network resources. Wireless personal area networks (WPan) relies on Bluetooth or infrared to establish a connection. The connectivity range is only 30 feet or so. The wireless wide area networks are also referred to as 2G networks; they use satellite systems to establish a network between countries, and so they offer worldwide connectivity and unlimited access to network resources. The wide area wireless connections can be set up at very cheap costs.

The technology used in most wireless networks is IEEE 802.11 and is commonly known as Wi-Fi. The WWans use 2G and 3G network technologies like CDPD and cellular wireless systems. As wireless communication is evolving it is getting better in terms of speed and range. Wi-Fi is popular worldwide and wireless computer and mobile phone devices like keyboards, security cams, mouse, headphones, televisions and much more are commonly in use today. People find it very convenient to get rid of wires and go wireless completely. These devices use infra-red as well as Bluetooth connections. Infra-red, however, is becoming obsolete as it requires linear range between the two devices which are to be connected. Bluetooth and Wi-Fi are the current prevailing trends in the technology market. Internet is connected using wireless routers which are easily available these days.
Wireless Devices
Wi-Fi has allowed people to stay connected anywhere at all times. It offers greater flexibility, effective communication which is cheap too and mobility for the users. Whether it is a global business world or social communities, the efficient wireless communication is serving the world in great terms by enhancing the processes and communication. Voice and video communications through computers or cell phone devices has truly revolutionized the world.

Wireless communication is stepping forward towards next generation networks; 3G is quite common worldwide but in developed countries 4G and LTE supported networks are also available. The future wireless technology aims to converge all forms of media to one device; a cellular phone. Whether it is about watching TV or calling someone, users will be able to do it all on one device. In addition to this, new forms of wireless communications are being developed which don’t rely on the internet; one such example is the VANET.

Although there are many technologies and different types of companies involved in bringing wireless communication to user level, some of the best wireless service providers working in the US include AT&T, Verizon and Sprint Nextel. Worldwide top names in wireless communication business include 4INFO, DSPc and PacketHop.

Future developments look forward to enhance the telecommunication infrastructure so that wireless communication can be used more effectively in developing the world as a whole.
