What is Mobile Data Networks

Handbook of Research in Mobile Business, Second Edition: Technical, Methodological and Social Perspectives
3G and 4G high-speed mobile networks that enable Internet access on mobile devices. 3G networks are circuit and packet switched and 4G is packet switched. Such networks use W-CDMA, CDMA2000, and WiMAX technology for 3G networks. OFDMA technologies such as Long Term Evolution (LTE) for GSM networks and Ultra Mobile Broadband (UMB) for CDMA networks and Mobile WiMAX are standards being proposed for 4G networks.

Abstract
Location-based services (LBS) are approaching an inflection point. The continued rollout of the technological infrastructure, the availability of LBS applications, and the market’s increasing awareness of their potential value should lead to increasing business opportunities. However, there is still a high degree of uncertainty in the LBS space. Challenges are emerging to the cellular network operator-centric LBS model. Hardware companies, application providers, competing infrastructure technologies (such as Wi-Fi, WiMAX, and satellite networks), and new competitors from the computer and Internet industries are all vying for market position. Customers are becoming interested in location services, but the uptake has been slow. New LBS business models and new strategies need to be considered. This chapter evaluates the future of location-based services through a critical assessment of the technology, service applications, market trends, and strategic issues.
