The cellular industry has been very successful in providing voice services to consumers and business. The next big opportunity for wireless networks will be differentiation based on data and multimedia services. Wireless service providers face ever-increasing pressure to offer innovative services, new capabilities, and make more efficient use of spectrum. In order to meet these needs, existing wireless networks have evolved with new technology both in the air interface and the core network. Specifically, the wireless mobile data communication technologies have evolved from the circuit switched second-generation (2G) networks to 2.5G and then to the third generation (3G) networks and beyond. The paper describes how the revolution of wireless communications, the wireless mobile data industry, evolution of wireless mobile data communication technologies, the wireless mobile data market and the failing barriers to wireless data proliferation.
