Wibro and WiMax

Competing standards include WiMax which is supported by by one of the technology's leading proponents, Intel. Part of the WiBro development work includes making WiBro compatible with WiMax, another emerging wireless specification. WiMax is designed for use over a number of miles, rather than the much shorter distances associated with the more established Wi-Fi and Bluetooth standards.  In November 2004, Intel and LG Electronics executives agreed to ensure compatibility between WiBro and WiMAX technology.

WiBro is a WiMAX-like system developed in South Korea to provide better data handling than 3G cellular networks can provide before 4G networks arrive. There are movements to integrate WiBro into WiMax, but the WiBro experiment is really about demonstrating demand for mobile, data-centric broadband networks alongside 3G. The advantage WiBro - and, by extension, WiMAX - offers over 3G is a more data-centric focus. It's also cheaper. Mobile phone networks will be willing to roll out higher speed 3G network upgrades based on the HSDPA (High Speed Data Packet Access) quickly, and even if they do, there remains the bandwidth limitations inherent in the technology's cellular architecture. The system needs to cater not only for voice users but multiple data users, all sharing the available bandwidth. If too many users attach themselves to a given cell, their bandwith will fall.

That said, WiMAX is not going to trample all over 3G, or vice versa. 3G clearly isn't going to go away, and even if it becomes the dominant high-speed data network, there's still a big opportunity for WiMAX in metropolitan areas
