2. What is WiMax? Worldwide Interoperability for Microwave Access Telecommunications technology that provides wireless transmission of data using a variety of transmission modes, from point-to-multipoint links to portable and fully mobile internet access. Enables the delivery of last mile wireless broadband access as an alternative to cable and DSL Also known as IEEE 802.16, that is intended for wireless "metropolitan area networks“.

3. The Next Generation

4. WiMax and Wi-Fi 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. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m). 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.tes over longer distances. Wi-Fi is more popular in end user devices.

5. 4G Network Evolution from 3G to 4G networks. Smart phones and "all-in-one" gadgets are driving the need for more bandwidth and QOS. Networks are becoming choked by increased smart phone data traffic. This problem is already accelerating the movement to 3.5G mobile data networks and will eventually push operators to 4G. 4G networks offer more bandwidth per user, and are more bandwidth efficient.

7. Strengths Long-range connectivity (two to five miles) Data rates up to 134 Mb/s High Quality of Service (QoS) Robust security Support for mobility Advanced antenna technology WiMAX has the potential to be used in a variety of fixed and mobile applications.

8. Weaknesses Very long-range connectivity (greater than five miles) – this is realistically achievable only with a high-quality external antenna and line- of-site service to the base station. Lack of available high-quality spectrum.

9. The United States Clearwire is the company that owns WiMax in the U.S. Started out at a few WiMAX hotspots in a few random cities has now grown into a service that's available to a variety of locations across the country. The engineers at Clear are doing their best to expand as quickly as possible to have a true nationwide 4G mobile data network. In 2010, Clearwire plans to launch 4G service in New York, Boston, Washington, D.C., Houston and the San Francisco Bay Area among others.
