What is WiMAX?
First Privious 1 2 Next Last
Worldwide Interoperability for Microwave Access known as WiMAX. WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX is the next-generation of wireless technology designed to enable pervasive, high-speed mobile Internet access to the widest array of devices including notebook PCs, handsets, smartphones, and consumer electronics such as gaming devices, cameras, camcorders, music players, and more. Many different products are being designed around the application of WiMAX. These range from laptops, ultra-mobile notebook PCs (UMPCs), Mobile Internet Devices (MIDs), and variety of handhelds.
WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations.
A typical user experience involves as a first step activating the device on a WiMAX network provided by an Internet Service Provider. Once subscription is complete, the user will be able to connect for service.
WiMAX provides two to three times the performance of 3G solutions today, with the ability to scale to ten times the performance in the future.
With WiMAX, data rates are easily supported, but the issue of interference is lessened. WiMAX operates on both licensed and non-licensed frequencies, providing a regulated environment and viable economic model for wireless carriers. WiMAX can be used for wireless networking in much the same way as the more common WiFi protocol. WiMAX is a second-generation protocol that allows for more efficient bandwidth use, interference avoidance, and is intended to allow higher data rates over longer distances. Soon, WiMAX will be a very well recognized term to describe wireless Internet access throughout the world.
Many companies are closely examining WiMAX for "last mile" connectivity at high data rates. This could result in lower pricing for both home and business customers as competition lowers prices.In areas without pre-existing physical cable or telephone networks, WiMAX will, it appears, be a viable alternative for broadband access that has been economically unavailable. Prior to WiMax, many operators have been using proprietary fixed wireless technologies for broadband services
