The development of mobile communications has traditionally been viewed as a sequence of successive generations. The first generation of analogue mobile telephony was followed by the second, digital, generation. Then, the third generation was envisaged to enable full multimedia data transmission as well as voice communications. In parallel to these activities related to the evolution of current wireless technologies, there is also an increased research effort on future radio access, referred to as fourth-generation 4G radio access.

WiMAX Applications for Public Safety

The name "WiMAX" was created by the WiMAX Forum, which was formed in June to promote conformity and interoperability of the standard, including the definition of predefined system profiles for commercial vendors. WiMAX Forum certification allows vendors to sell fixed or mobile products as WiMAX certified, thus ensuring a level of interoperability with other certified products, as long as they fit the same profile. The original IEEE Mobile WiMAX originally based on WiMAX was sometimes referred to as "Wi-Fi on steroids" [5] and can be used for a number of applications including broadband connections, cellular backhaul , hotspots , etc. It is similar to Long-range Wi-Fi , but it can enable usage at much greater distances.

Many public safety organizations have used Wi-Fi systems to take advantage of the common access and minimal costs available in the license-exempt spectrum bands. One of the major issues related to Wi-Fi though is the limited range that results from the maximum power available coupled with the restrictions associated with the interference acceptance requirements. In a follow-on effort, the industry has attempted to resolve many of the issues of Wi-Fi by developing the next generation of wireless local area network 1 WLAN technologies. The first wireless local area network WLAN technology called Wi-Fi was developed in under the auspices of the Wi-Fi Alliance to satisfy a demand for short range wireless access for local area networks. This technology was developed in response to the FCC spectrum allocations for license-exempt use under Part 15 of the Rules.

Mobile networks are experiencing a great development in urban areas worldwide, and developing countries are not an exception. However, sparsely populated rural areas in developing regions usually do not have any access to terrestrial communications networks because operators cannot ensure enough revenues to justify the required investments. Therefore, alternative low-cost solutions are needed for both the access network and the backhaul network. In this sense, in order to provide rural 3G coverage in small villages, state-of-the-art approaches propose to use Small Cells in access networks and inexpensive multihop wireless networks based on WiFi for long distances WiLD or WiMAX for backhauling them. These technologies provide most of the required capabilities; however, there is no complete knowledge about the performance of WiFi and WiMAX in long-distance links under quality of service constraints. The aim of this work is to provide a detailed overview of the different alternatives for building rural wireless backhaul networks.

Networks integration is crucial criterion for next generation wireless networks, where the diverse of the technologies available has been optimized for different usage models. WiMAX and WiFi are the most promising techniques for future wireless networks; interworking between these technologies is inevitable for better usability of the networks infrastructure and support for seamless mobility and roaming. The unique similarities between WiMAX and WiFi networks that make the proposed synergy promising and meaningful that both technologies are fully packet switching uses IP-based technologies to provide connection services to the Internet. This standards- and IP-based network approaches provide compelling benefits to service providers to collaborate between these technologies.
