Wireless communication networks play an important role in anybody's life during this information age. The technology is growing at a rapid rate and it becomes essential to provide a reliable linking to the system using an appropriate uplinking channel with the required Quality of Service (QoS). The paper presented here deals with important Long Term Evolution (LTE) of techniques developed over last two decades. Power optimization of the mobile unit is the most desired operation which is discussed. Towards achieving seamless transmission, Frequency Hopping Spread Spectrum (FHSS) is used in wireless communication.
