WIRELESS COMMUNICATION (3G VS WI-FI)

WIRELESS COMMUNICATION (3G VS WI-FI)

ABSTRACT

This paper offers a qualitative comparison of two wireless technologies that could be viewed simultaneously as substitute and complementary paths for evolving to a broadband wireless access. The two technologies, 3G, which is the preferred upgrade path for cellular providers, and WiFi, one of the many WLAN technologies that offers an alternative platform for providing wireless access.

The former, 3G, refers to the collection of third generation cellular technologies that are designed to allow mobile cellular operators to offer integrated data and voice services over cellular networks. The latter, WiFi, refers to the 802.11b wireless Ethernet standard that was designed to support wireless LANs.

Although the two technologies reflect fundamentally different service, industry, and architectural design goals, origins, and philosophies, each has recently attracted a lot of attention as candidates for the dominant platform for providing broadband wireless access to the Internet. If they are viewed as in competition, then the triumph of one at the expense of the other would be likely to have profound implications for the evolution of the wireless Internet and service provider industry structure.
