This paper summarizes how one can make use of 4th generation of wireless communication to control Ground Combat Vehicle which is the Army's replacement program for armoured fighting vehicles in Heavy and Stryker brigade combat teams. Robotics in army is an interesting field where every engineer can showcase his creative and technical skills. As the development of individual and cooperating autonomous robots advances, the need for robust and reliable communication method becomes apparent. This paper summarizes a the feasibility of implementing Dual-Tone, Multi-Frequency (DTMF) as an alternative mean of robotic communication to Radio Frequency (RF) for controlling the Ground Combat Vehicle which will remove the need of human being to be involved physically in the battle. The user in order to control the vehicle should make a video call to the 4G enabled phone attached in the Vehicle, from any another 4G enabled phone, which can send DTMF tones by pressing the numeric buttons and can view the video output. The cell phone in the vehicle is kept in auto answer mode. So, after a ring the cell phone accepts the call and starts video transmission. This article provides an in-depth view on the technologies being considered for Long Term Evolution-Advanced (LTE-Advanced). First generation (1G) wireless telecommunication is the term related to analog phones that are now collector’s items - introduced the cellular architecture that is still being offered by most wireless companies today. Second generation (2G) wireless supported more users within a cell by using digital technology, which allowed many callers to use the same multiplexed channel. But 2G was still primarily meant for voice communications, not data, except some very low data-rate features, like short messaging service (SMS). Socalled 2.5G allowed carriers to increase data rates with a software upgrade at the base transceivers stations (BTS), as long as consumers purchased new phones too. Third generation (3G) wireless offers the promise of greater bandwidth, basically bigger data pipes to users, which will allow them to send and receive more information.
