Broadband Wireless and Bluetooth-Based Communications Thesis

Of these three approaches ad-hoc is considered the most adaptable to roaming users and therefore shows the greatest opportunity to support contextual-based use of wireless networks. The concept of the cellular network on the other hand is much more stationary and focused on a set of base stations that require base controllers and network infrastructure to effectively function. This fixed platform nature of the cellular network approach is juxtaposed with the approach increasingly being relied of using ad hoc networks for enable peer-to-peer communications throughout wireless networks. This aspect of ad hoc wireless network architectures is gaining high levels of interest due to wireless due to WiFi-enabled devices being able to access Facebook, MySpace and other social networking applications. As the ad-hoc architecture inherently supports peer-based communications and is rapidly becoming the foundation of social networking, this type of network architecture is considered highly distributed in nature. Often wireless network providers will have multiple architectures supported within a given network to ensure each role of WiFi users is adequately supported. For the business user the need for a secured connection with IPSEC-level security requires the use of cellular-based networks, yet there also needs to be allowances for creating ad-hoc-based network architectures and topologies to enable social networking. The trade-offs in system architecture are ultimately balanced between frequency spectrums and access techniques. In conclusion, the current state of wireless computing, when analyzed from the context of access techniques, frequency spectrums and architectural considerations, shows that there are entirely new, high bandwidth applications on the horizon that will make it possible to send and receive digital content including streaming video in real-time before the end of the decade.
