Wireless Technology LTE
LTE, which stands for long term evolution is a form of wireless technology which is aimed at upholding roaming internet access through the use of cell phones among other devices. It is a huge step in advancing in the wireless industry. In its physical layer it uses the OFDM waveforms to evade interference. In LTE on its onset MIMO is an integral part and not just an inclusion, in the network layer there is combination of the circuit and packet switched networks to an IP system. This same technology is similarly use in the LTE+. While LTE+ is an advance form of the wireless technology or otherwise improvement of the earlier communication levels, it adds efficiency to the performance of the networks. Users of such devices are able to access internet from their devices. LTE does enable a higher speed to be gotten at a much lesser packet latency, it also offers high efficiency and LTE+ makes it possible for cellular communication to go ahead and access the requirements for cellular technology for the future years. LTE+ the number used for the primary component carriers and physical cell IDs are of limited, it also makes use of decode-and-forward relaying.
LTE offers a high performance and capacity of a peak rate of 100Mbps, while the LTE+ offers a higher rate with over 300Mbps. The LTE has a bandwidth which is flexible ranging from 1.4MHz to 20MHz while the LTE+ has a bandwidth of 10MHz to 20MHz (Leung Cyril and others, 2011). the features which they possess are self-configuration and self-optimization which enable its simplicity and ease to access due to its cheap nature LTE has a mobility of 350 km/h. The modulations applied by LTE are BPSK AND QPSK which is applied as they are not hard to detect at a specific signal-to-noise ratio and interference ration (Ericsson, 2011). The radio access network number of trips in LTE is less than 10ms, meaning it meets the 4G need.
