An Overview

Telecommunications standards are constantly changing as technology advances and the public’s hunger for more content delivered to their portable devices faster is a driving force behind these developments. At the moment a majority of modern mobile phones and mobile broadband services for PC and Laptop owners connect to 3G networks. This name refers to the fact that this is considered to be the 3rd generation of mobile telecommunications networking technology, and at the moment 3G networks are capable of download speeds of between 3.6 Mbps and 7.2 Mbps. This speed will depend on the network provider, the level of 3G coverage and the capabilities of the mobile platform which are using to receive the signal.

At the moment 4G technologies are looking to be similar in many ways to the wireless networks that are used work place or in home, only on a much larger scale and integrated into mobile devices as well as desktop solutions. For mobile users it will provide an `always on` mobile broadband connection so that voice calls, media streaming and internet access will be constantly at hand. Additionally the download speeds capable over 4G networking should be far greater than is currently available on 3G or indeed any home broadband service provided by a landline, with test 4G networks in China delivering 100 Mbps download speeds. What`s even better news is that this 100 Mbps speed is claimed by some companies to be the download speed available when the subject is on the move in a train or a car. If you're standing in one spot relative to the broadcasting beacon then up to 1 Gbps data transfer speed could be possible. This is literally an incredible development and a huge leap in terms of download speed and will no doubt further revolutionize the way in which we have access to the internet, as well as drastically lowering the cost of voice calls which use relatively little bandwidth. At the moment most people have mobile phones and many will also use wireless broadband, either in their own homes thanks to a wireless router or through a mobile broadband solution using 3G networks.

The IMW-C220W, a WiMAX terminal with WiFi capability made by InfoMARK Co., Ltd, South Korea, is a telecommunications device optimized for indoor usage such as offices and houses. The terminal functions as a relaying device by communicating with outdoor antennas through WiMAX signals and converting them into WiFi (wireless LAN) signals for indoor equipment. Using this terminal, a regional WiMAX service provider can deliver a wireless internet service for a range of WiFi devices, such as notebook PCs and game controllers, without requiring any cabling work into the building. Also, the IMW-C220W is equipped with a LAN cable port, enabling it to be connected to a desktop PC etc. using a LAN cable.

The IMW-U320 is another WiMAX terminal made by InfoMARK. This is a compact USB-type WiMAX terminal that can be installed in a PC simply by inserting it into a USB socket. The terminal adds WiMAX communication capability for both indoor and outdoor use to a PC. The terminal is fully equipped with an antenna in its USB memory stick-sized body, weighing only 14 g and delivers a wireless communication service to users on the move-as long as they are within the coverage area. These terminals are tried and tested by Korea Telecom, the provider of the WiBRO service, which is the Korean equivalent to the WiMAX service.
