LTE which stands for Long Term Evolution is one of wireless broadband technology which provides an increased on both network capacity and speed to user. As LTE network grows, LTE mobile data services becomes demanding mode of communication. From audio call to video conference, video conference to online bank transaction, user lives conveniently with LTE. The speed of LTE network is up to 300 Mbps with the coverage of 100 km. However, LTE network could not be standalone on this chain for so long as it might occur generalization of services where the quality cannot be guarantee. Here Quality of Service (QoS) play it roles in managing and design wireless services that suit every single user necessity. QoS refers to the ability of a network to accomplish maximum bandwidth and handle with another element within network performance. Not to mention, minor support that made this possible is by studying on how EPC could make a different in improving the QoS in LTE network. Evolved Packet Core (EPC) is designed to support smooth transfer for voice and data to a base station. Hence, investigation in benefit of EPC toward QoS in LTE is carry out and simulation result obtained will be evaluated throughout this paper.

Wireless Mesh Networks are a very attractive new field of research. Mesh networks are low cost, easily deployed, and provide high performance solution to broadband network access. Multiple Inputs and Multiple Outputs (MIMO) is one of the radio technology breakthroughs for increasing network capacity to obtain the full benefits in wireless mesh networks. The proposed research investigates the network routing, channel assignment, capacity of MIMO channel with number of transmit and number of receive antennas in wireless mesh networks. This paper also focuses an intelligent Teaching-Learning-based Optimization (TLO) algorithm to find the optimal network routing path between source and destination for Wireless Sensor Network (WSN). Compared with other routing metrics, the simulation results show that the proposed algorithm converged quickly and reached the optimal solution with minimal time and also improve the network performances.

Recently, extensive research attention has been dedicatedto enabling Orthogonal Frequency-Division Multiplexing (OFDM) waveforms to be compatible with a modern communication system. Encoding data as OFDM wavelengths still has a lot of problems, like the peak-to-average power ratio (PAPR) and the cyclic prefix (CP), which are important factors that affect how efficiently the spectrum is used. To meet the quality-of-service requirements imposed by communication system applications, this paper proposes to replace the classical encoding and decoding schemes, classical channel, discrete Fourier transform (DFT), and inverse discrete Fourier transform (IDFT) with their classical counterparts. This new quantum OFDM transmission scheme allows for the preparation of a quantum OFDM symbol without the need to incorporate a CP. To validate the accuracy of the suggested quantum OFDM transmission scheme, we compared it with the most widely recognised reference quantum transmission scheme. We have demonstrated that increasing the channel resistivity results in a higher probability of correctly measuring the quantum state in the quantum OFDM transmission scheme compared to the reference quantum transmission scheme. The results are verified by IBM's Qiskit.
