Third Generation (3G) and Fourth Generation (4G) are cellular telecommunication networks that supports multimedia and broadband services (Turban & Volonino, 2011, p. 96). 3G is an evolution of 2G and 4G a successor of the 3G. These network services are sold through telecommunication service providers. Users of these networks can enjoy surfing the Internet, checking email and downloading content from the convenience of their mobile devices enabled to use the technology (Gowthami, Ramya, and Nishanthi, 2012, p 1). Below is the comparison and contrast of 3G and 4G.

The main difference between 3G and 4G is speed. 4G delivers average download rates of 3 Mbps or higher, whiles 3G networks deliver average download speeds of about one-tenth of that rate (Turban and Volonino, 2011 p 96). Most 4G have higher bandwidths of about 100 Mbps as they are expected support multimedia services. What is also significant is that 4G networks are entirely packet-switched networks in contrast to the3G network, which consists of both circuit switched and packet switched domains. The reason for this is that in 4G, the IP is anticipated to be used as the packet switched network .

Another important contrast between 3G and 4G lies in their connectivity. Because 3G relies on area-specific connectivity, many users have experienced problems with 3G connections in certain areas. For example, if you live in an area where the 3G connectivity is officially low (or non-existent), then you will not be able to benefit from its full services. Instead, you will most likely be reconnected to 2G "EDGE" capabilities, which offer a much slower speed. Even in areas where 3G connection is known to be well-received, there have been reports of inconsistent reliability because of various hardware and software issues. But 4Gwireless networks that support global roaming across multiple wireless and mobile networks—for example, from a cellular network to a satellite based network to a high-bandwidth...
