Everything You Need To Know About 4G Wireless Technology

While most of us are used to getting high speed Internet connections at home, the office or even the local coffee shop, once we are on the road those high speeds have to stay behind. With 4G the promise is that you can get real mobile broadband to go. In this piece we are going to tell you all about the technology and its benefits, who offers it or plans to, how much it costs, and the gear you need to enjoy the next generation of wireless broadband today.

In telecommunications, 4G is the fourth generation of cell phone mobile communications standards. It is a successor of the third generation (3G) standards. A 4G system provides mobile ultra-broadband Internet access, for example to laptops with USB wireless modems, to smartphones, and to other mobile devices. Conceivable applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing and 3D television.


Speed like you’ve never seen before

Okay, lets put it this way. 3G’s thoroughput is about 3 mbps. So, as speeds go, 3G is pretty fast. That is, until you consider 4G. Providers claim that 4G has the potential estimated to be 10 times that. In the range of 100 – 300 mbps, to be precise. Unbelievable? Maybe. Practically speaking, experts say it will be average about 3-5 mbps, which on your mobile phone is seriously fast.

Video chats/calls

Finally Skype, video conferences and video calls will never be more fun to use than when 4G kicks in. Since the networks are fast and consistent, they will support cheap VoiP services, making video finally viable.

Wi-fi hot-spots

At long last, 4G might force us to wake up to the infinite po­tential of the devices we access, coercing the network providers to offer wi-fi hotspots around the country therefore making it ideal to access 4G devices.

Unlimited Usage

Many complain that 3G networks are crowded, and carriers put caps on how much data you can use per month. On the other hand, 4G with its incredible ba­ndwidth might be more in­clined towards offering truly unlimited plans, letting you use as much as bandwidth as you want.


Major differences in 2G, 3G, 3.5G & 4G
Two 4G candidate systems are commercially deployed: The Mobile WiMAX standard (at first in South Korea in 2006), and the first-release Long term evolution (LTE) standard (in Scandinavia since 2009). It has however been debated if these first-release versions should be considered as 4G or not. See technical definition. In the U.S. Sprint Nextel has deployed Mobile WiMAX networks since 2008, and MetroPCS was the first operator to offer LTE service in 2010. USB wireless modems have been available since the start, while WiMAX smartphones have been available since 2010, and LTE smartphones since 2011. Equipment made for different continents are not always compatible, because of different frequency bands. Mobile WiMAX and LTE smartphones are currently (April 2012) not available for the European market.
