Long Term Evolution (LTE) is the 4th generation of cellular telecommunications technology. According to the standard, LTE provides uplink speeds of up to 50 Mbps and downlink speeds of up to 100 Mbps. In the Denpasar area is a region that has a high level of data package usage, especially LTE technology, which is an average of 83,790,262 Gbits per day, because this area is an area with a fairly dense population. The method that is currently widely used to determine the quality of a network is the Test Drive method. In this study, the author will take a sample of RSRP values for distances of 100 - 400 m in BTS L_Bundaranrenon_PL, BTS L_Akaba_PL and BTS L_Myamin_CR owned by PT. Indosat. In the results of the study, by comparing the RSRP value of the simulation results using the Atoll Software with the RSRP value from the Test Drive obtained a correction factor value, which will then be added to the simulation to get a RSRP value closer to the simulation using the Atoll Software with the Test Drive results. Correction factor value obtained after adding attenuation to the simulation for housing conditions the maximum margin value is -4.99 dBm, while for the open area condition the maximum margin value is -4.22 dBm.

Term Evolution

Many studies have shown a global efficacy of laparoscopic surgery for patients with endometriosis in reducing painful symptoms and improving quality of life (QoL) in the short and long-term. The aim of this study was to analyze the different trajectories of long-term evolution in QoL and symptoms following surgical treatment for endometriosis, and to identify corresponding patient profiles. This prospective and multicenter cohort study concerned 962 patients who underwent laparoscopic treatment for endometriosis. QoL was evaluated using the Short Form (SF)-36 questionnaire and intensity of pain was reported using a visual analog scale prior to surgery and at 6, 12, 18, 24 and 36 months after surgery. Distinctive trajectories of pain and QoL evolution were identified using group-based trajectory modeling, an approach which gathers individuals into meaningful subgroups with statistically similar trajectories. Pelvic symptom trajectories (models of the evolution of dysmenorrhea, dyspareunia and chronic pelvic pain intensity over years) correspond to (1) patients with no pain or pain no longer after surgery, (2) patients with the biggest improvement in pain and (3) patients with continued severe pain after surgery. Our study reveals clear trajectories for the progression of symptoms and QoL after surgery that correspond to clusters of patients. This information may serve to complete information obtained from epidemiological methods currently used in selecting patients eligible for surgery.

Mobile broadband utilizing Long-Term Evolution (LTE) has advanced the field of data transmission; with networks capable of providing broadband speeds to mobile broadband users. There has been a sporadic increase in the utilization of Long-Term Evolution (LTE) networks, but due to the rapid growth and utilization of network links and network services, certain issues begin to rise, such as the issue of poor Quality of Service (QoS) perceived by mobile users. Data network quality of service degrades over time when network cannot keep up with the growing demand for the network resources. The research reviewed various existing content delivery network models in order to understand the overall architecture and operations. An optimized model was developed and integrated into the existing Long-Term Evolution network models. The model was evaluated using the Network Simulator (NS-3) and Quality of Service (QoS) metrics, such as, Network Throughput, Round Trip Time, Bandwidth, Packet Loss, Jitter and Connection Ratio. The results obtained from the simulations showed that the optimized model performed better and more efficiently than previous solutions. And if implemented in Mobile Broadband, this will improve the Quality of Service, network throughput and overall performance of the network. This study concluded that cloud-based content delivery network provides a solution which would help improve the Quality of Service experience by Mobile Broadband subscribers. By actively redirecting network traffic to the nearest replica server on the network edge; thus, increasing efficiency and throughput.

Handover Mechanism

One of the key elements in the networks LTE (Long Term Evolution) is the possibility of deploying multiple femtocells for the improvement of coverage and data rate. However, arbitrary overlapping coverage of these cells makes the handover mechanism complex and challenging. In this paper, simulations of deploying LTE femtocells in a scenario were evaluated. With this objective, measure impact and correlation of the use of femtocell parameters of QoS (Quality of Service) and handover. Possible limitations of this integration are discussed. Will be the integration of LTE femtocell a panacea? Despite this promising alternative estimates are fraught with uncertainty. The results show that the use of femtocell got worse on indicators of handover, impact on indicators of QoS.

Frequency Division Duplexing

The study aims to analyze the Quality of Service (QoS) of Long Term Evolution Frequency Division Duplexing (LTE FDD) telecommunication network in urban and sub-urban in Semarang city. This study observed the quality of the LTE FDD in terms of network responsiveness or ping, packet loss, delay, and throughput on upload and download from the user's experience based on eNodeB length variation. Quality observations were carried out on the QoS of the LTE FDD telecommunications network in the Semarang using the Axence NetTools and Oakla Speed Test applications during busy hours at each eNodeB. The results were presented based on variations in distance and showed the quality of packet loss and delay classified as very good based on ITU-T G.114, which is respectively less than 3% and 150 milliseconds. Ping testing was classified as good based on the LTE control plane, which is less than 50 milliseconds at each point. Service throughput was between 16.98-19.01 Mbps for uploads and 17.34 - 23.29 Mbps for uploads.
