Wireless internet is relatively new but the technology on which it is based on has a long history. It has its roots with radio communications. Radio signal was first discovered by Heinrich Herz, and a few years later Marconi used it to send and receive messages across great distances. From those early discoveries and innovations the wireless internet that we now have is largely based.
Even before internet networks came to existence there have been some computers connected through a wireless network. The first and most significant of this was the ALOHNET which was created in the University of Hawaii. There were a total of seven computers in that network and they communicated by radio signals. It seems primitive now in retrospect but it was at the vanguard of computer and network technology back then.
By the late 1980s and the early 90s the Internet grew steadily. It was then realized by the experts that it would be a lot better if users can be connected by a wireless network instead of depending on cumbersome cable connections. Therefore, wireless internet technology was created.
There are currently four generations of wireless internet. These range from the G1 or 1st generation to the 4g wireless internet. 1G was introduced in the early 1980s when the first cellular networks were established. 1G still utilized analog transmission and is quite unreliable when compared with later technologies.
When 2G was introduced in 1992, it was hailed as revolutionary since it was the first technology that utilized digital transmission. That eliminated most of the problems that were inherent in 1G. In 2001 3G was introduced which supported multi-media which is the beginning of the internet as we know it today.
Right now there are two technologies that are being considered as candidate systems for 4G internet in most countries. These are the Mobile WiMAX and the Long Term Evolution which was first released in Europe. Both forms of 4G internet bring with them rich multimedia possibilities, with bandwidth and network capacity capable of streaming high quality videos, audio and gaming on the go.
Australia was one of the world’s early adopters when it comes to 4G, with many of the local Telco companies such as Vividwireless establishing networks very quickly, particularly in CBD areas. This is mainly due to the fact that Australia has one of the highest levels of smartphone ownership per capita, and the thirst for data is continuing to climb month on month. With multiple 4G networks now up and running this thirst can be quenched!
