A comparative overview of modern communication systems and standards

Abstract: With the dynamic changes in technological advancements, wireless communicationtechnologies has made a tremendous progress from simple to complex systems that are able tocommunicate across multiple networks platform. As these systems continue to prove theirproficiency and benefits, it is strongly asserted that wireless technologies will continue to play aneven more critical and vital role compared to wired connections in the future. The most relevant question now regarding the future of wireless technologies is whether it going todominate the wireline transmission or be a complementary to wireline where it’s difficult for anyreason to have wireline like wireless backhaul. With today’s wireless data rate speeds it would bedifficult to imagine it replacing wireline in the near future, but technically speaking it is feasible toachieve those data rates with use of wider spectrum. Moreover, wireless communication technologies particularly that of wireless mobile phonetechnology, is continuously more preferred in communication today, making it the first priority ofmodern day lifestyle. Modern communication system standards have therefore been subjected toevaluation and analysis to establish a more profound understanding of these various technologies.The proposed study presents an overview of various wireless communication systems such as:Global system for mobile communications (GSM), high-speed packet access (HSPA), long-termevolution (LTE), mobile WiMAX, ultra wideband (UWB) technology, ultra mobile broadband(UMB), wireless local area network (WLAN), Bluetooth wireless technology, and, Wi-Fi.
