Humans are never satisfied with what they have and they always want more! First thay had 3G and now they have 4G, the 4^th generation wireless technology that is believed to totally replace all the previously available broadband mobile communications technology. The new 4G networks provide the same convenience and usability on a cellular phone that a user can do wired to a PC, i.e., if a consumer can surf at home or in the office while wired to the Internet, that consumer must be able to do it wirelessly in a fully mobile environment.  

4G also provides high data rates, supports global roaming and multiple classes of service with variable end-to-end Quality of Service (QoS) requirements across heterogeneous wireless systems. 4G networks, when coupled with cellular phones equipped with higher quality digital cameras and even HD capabilities, will enable vlogs to go mobile, as has already occurred with text-based moblogs. New models for collaborative citizen journalism are likely to emerge as well in areas with 4G connectivity.   

Technologies employed by 4G include Wide-band Orthogonal Frequency Division Multiplexing and SDR (Software-defined radio) receivers along with other features. With the advancement in technology this new 4G technology makes sense because consumers will want to use the same data applications they are used to in wired networks.
