The demand for wireless communication is increasing day by day. People want a high speed of communication in less time. Nobody is interested in using a lot of cables. Then we move to wireless communication. As technology increases, demand also increases. Now everyone wants a fast communication from anywhere to anyone. Even the rural area also requires an Internet facility. It is very difficult to establish a base station for a small village in particular for broadband communication or any wireless communication. It is even too expensive to launch a satellite for a particular rural area. Therefore, the engineers did an intermediate way of satisfying both terrestrial-to-satellite and satellite-to-terrestrial data transfer facilities via HAP (high altitude platform). HAP is operated at an altitude of 17-22 km. HAP provides wireless communications facilities.
In the current era, the demand for wireless communication increases markedly. A terrestrial and satellite system provides wireless communication services. Terrestrial systems are used in mobile applications, while satellite systems are used when the terrestrial system is not reached. HAPs are dirigibles or airplanes whose altitudes are 17-22 km above the earth's surface. PAHs have proposed mobile services in the stratosphere. It has both terrestrial and satellite advantages. It also offers services like 3G, emergency services and Wi-MAX. HAP networks provide different services, such as military applications, ground monitoring, monitoring and traffic control. In terms of services, HAP offers services of low cost and high facility.
