Essay on Emerging Wireless Technologies
A look into the future of wireless communications – beyond 3G
Forward: The Public Safety Wireless Network (PSWN) Program is conducting an ongoing assessment of advancements in the wireless communications industry. The scope of this assessment is to identify emerging wireless services and technologies for potential public safety use in the near future and beyond. This particular document is the first of a series of emerging wireless technologies studies. This study will concentrate primarily on the fourth generation of mobile telecommunications and beyond.

easy transition from existing systems to LAS-CDMA (using software defined radios). LinkAir emphasizes that LASCDMA will accommodate all the advanced technologies planned for 4G and that LASCDMA will further enhance either 3xRTT or W-CDMA system’s performance and capacity. Internet Speeds 2.5G is the interim solution for current 2G networks to have 3G functionality. 2.5G networks are being designed such that a smooth transition (software upgrade) to 3G can be realized. 2.5G networks currently offer true data speeds up to 28kbps. In comparison, the theoretical speed of 3G can be up to 2 Mbps, i.e., approximately 200 times faster than previous 2G
