AT &T focused on augmenting its current 3G transmitter locations with the HSPA+ upgrade but overlooked the possibility of expanding its coverage area by not initially building towers and transmitters in location previously not supported by their current mobile capabilities. (Cox, 2012) Verizon has however invested a significant amount of money in to the development of new towers and transmitters that support 4G Long Term Evolution (LTE) mobile communications capability which is rapidly becoming the mobile industry’s standard. (Cox, 2012) Verizon Wireless and AT&T believe 4G LTE subscribers can expect average downlink speeds of 5M to12Mbps and 2M to 5Mbps on the uplink. By comparison, the fastest 3G networks can only support an average downlink speed of 600K to 1.4Mbps and 500K to 800Kbps sending data. Verizon’s 4G LTE infrastructure is capable of supporting data transmissions rates in excess of ten times the speed of data being transferred over their nearest competitor AT&T. (Cox, 2012) Experts in the field of mobile communication still label AT&T’s data speed as being slightly faster than traditional 3G technology; whereas, AT&T’s marketing department sells it as a 4G mobile technology to uninformed consumers.
