Yantai Unicom uses different frequency networking to optimize the campus network coverage of Ludong University

This year, Ludong University has added nearly 6,000 users, and the number of full-day traffic and data traffic has doubled compared with freshmen before enrollment. In view of the large and dense number of room branch sites in Ludong University, according to the WCDMA neighbor configuration characteristics and scrambling code planning rules, if the indoor and outdoor co-frequency networking method is used, it will not meet the actual needs.

In order to enhance the deep coverage of Ludong University campus and enhance student user perception, Shandong Yantai Unicom innovatively adopts a combination of macro station and room division frequency networking, which not only meets the needs of neighboring area configuration, but also greatly helps optimize network quality. The dual-carrier deployment of 13 base stations in and around the campus and the expansion of WBBP boards of 3 base stations have been completed, and 37 indoor distributions have been optimized. After the rooms are separated, Yantai Unicom also organizes indoor and outdoor switching tests for each dormitory area, using different switching and reselection parameter optimization to ensure that the indoor distribution of each dormitory area is normal.

After capacity expansion, the blocking rate of the entire network is close to 0, and each success rate index and handover success rate index are above 99%. The opening optimization of Ludong University's room division frequency networking greatly absorbed the traffic of the macro station, eased the network load of the macro station, significantly improved the user's perception, and provided a reference for future optimization work.
