    An implementation of Mobile network providers on 5G network are coexistence between LTE-LAA and LTE-LWA network. It was applied to achieve the objective of improve network performance and optimize resources. This paper is study the investigated LTE-LAA and LTE-LWA coexistence with Wi-Fi controlled Technique in different scenarios. The results show the distance between 50-600 meter and LTE-LWA was extremely affect by LTE-LAA. The controlled Wi-Fi AP technique is effective method to mitigate the network degradation problem.

    This paper presents the design of the LTE-Pro network in the combination of LTE-LAA and LTE-LWA. By designing appropriate distance, density as a ratio and bandwidth allocation between 3 technologies in order to find the suitable cell location that enables the high throughput. From the variation between LWA (Wi-Fi Access point) or LAA (eNB) and Base Station (BS) to find Inter-Cell Interference Coordinate (ICIC) from the nearby BS via signal to interference plus Noise Ratio (SINR). The assumption that LAA node and LTE node had different radius, while LWA was randomly distributed between the distance D1 and D2, respectively. Then the ratio number of nodes and allocate frequencies bandwidth between 3 technologies. By using MATHLAB to simulate the operation of the LTE-Pro network. The results show that the design of the pico LTE-pro network with the range D1 is 3 : 4 of the LAA radius, and D2 is 4 : 5 of the LTE radius. The node ratio and the bandwidth allocation of LTE : LAA : LWA is 2 : 2 : 10 and 2 : 4 : 4 respectively are factors that affects the performance of LTE-Pro and will improve LTE-Pro network performance.

    Impact of LTE-Pro on LTE-A Network

    This paper presents the design of LTE-Pro network performance in LTE-LAA and LTE-LWA interoperate scenarios. By offering data flow controlling technique, and modification between Time Division Duplex (TDD) and frequency division duplex (FDD) techniques on downlink sides. In order to find an optimal cell position that enables the data transmission in the communication channel or Throughput. From the variation of User Equipment (UE) and Node (eNB) or Base Station (BS) to find the Inter-Cell Interference Coordinate (ICIC) from other nearby BS via Signal to interference plus Noise Ratio (SINR). Assuming that the nodes of the LLA and LWA are distributed randomly, the distance is between 50-1, 200 meters. By using MATHLAB program to simulate the LTE-Pro network. The results showed that when the distance increased, the Throughput decreased in both cases and concluded that the 600 meters distance is the distance that affects the performance of LTE-Pro. And if the LTE-Pro network is to perform well, it must make the uplink and downlink Wi-Fi signal transmission to be FDD and TDD respectively.

    Implementation of the mobile network provider to improve the network performance and the resources optimization by implemented coexistence LTE-TDD, LTE-FDD network and Wi-Fi technology. The main interference is the adjacent cell interference (ACI) from coexisting network/technology, which affected to the network performance. This paper is investigated LTE/Wi-Fi technique in coexistence LTE-FDD/TDD. Results show the distance between 50-60 m and Wi-Fi access point should not over 12 given the best system. The throughput compared with normal case will describe in this paper.

    Mobile network Operator is implemented coexistence LTE-TDD and LTE-FDD network, this technique used to improve the system capacity. The adjacent cell interference or ACI caused by these coexisting networks, which affected to the network performance. This paper investigates the load sharing technique to optimal the capacity of coexistence LTE network. Results show 4:6 of FDD and TDD user ratio that give maximum system throughput and comparing with power allocation and guard band technique will describe in this paper.
