4G: Fourth-Generation Broadband Technology

4G is a fourth-generation broadband telecommunications network that offers a secure IP-based connection wherever you are. It's "anytime, anywhere" connectivity that offers high speeds for bandwidth-heavy applications like voice, data, and video services. You'll be constantly connected, able to access the same applications that you'd access on a wired connection, just as quickly.

4G Broadband Network Benefits

The two main benefits of 4G are simple, but powerful. First, users will be able to roam across different networks with one device. Wireless devices will automatically connect to the best network available – be it LAN, GSM, 3G, 4G, or something else – allowing for seamless handoffs from congested networks to less congested ones. You get greater efficiency and lower costs.

The second benefit of 4G is significantly higher bandwidth because of its all-IP packet-switched infrastructure. Packet switching splits data into small chunks that are transmitted across the network and reassembled at the destination point. These packets take the most efficient route to get to their destination, lowering the overall time it takes data to traverse the network. Thus packet switching optimises network capacity, minimises delays, and increases overall bandwidth. A 4G broadband network supports high-quality multimedia streaming services while handling more simultaneous connections.

Implementation of IPv6

Due to the dearth of IPv4 addresses, 4G will bring about widespread IPv6 support. IPv6 increases the number of available IP addresses, which is necessary in 4G broadband networks because there are so many connected devices. With everything from your mobile to your refrigerator constantly connected to the network, IPv6 will be a necessity.

Seven to Build 4G Broadband Network

Seven Network recently announced that it will build the nation's first 4G broadband network. Its new subsidiary, Vivid Wireless, will roll out a $50 million network in Perth, which is currently underserved by the wireless broadband market. Starting in March 2010, customers will get speeds of up to 20 Mbps at competitive prices, 10 times faster than their current 3G networks. If the project is successful the company may expand to other capitals, as well.

National Broadband Network

Vivid Wireless does not expect its 4G network to compete with the Government's National Broadband Network (NBN). It believes the two options are complementary – the NBN is a fixed service while the 4G network is a wireless solution that ensures mobility.

4G offers ubiquitous computing – connectivity everywhere, all the time, on any network. It allows you to move automatically and seamlessly from one congested network to a less congested one; access will be quicker and more efficient, even with many more devices connected. Basically, if you can do it at home on the wired Internet, 4G will let you do it in a fully wireless environment, too. It will transform your mobile into a comprehensive communication, entertainment, and productivity platform small enough to fit in your pocket.
