However, in the case of small inter-site distance, Pb and Pa values of 0 might provide a more optimized solution as in this case, the RS power will not be boosted compared to the PDSCH symbols.Īnother factor is the load in the area or cluster. If the inter-site distance is large then Aglocell utilizes this parameter as a 3dB Reference Signal boost that improves coverage as coverage is controlled with RSRP and RSRP is the direct outcome of RS power. When the inter-site distance is low, then high reference signal power can result in higher interference. Pa & Pb: Another parameter Aglocell utilizes in the case of smaller inter-site distance is to use a more balanced RS power (Reference Signal).So, it is a good idea to keep this in mind in the design or expansion phase. If the network uses the same RET port for 4G and 5G then any change on LTE tilt will impact the other RAT and it takes away the flexibility. That provides flexibility for optimization. Electrical Tilt Ports: It is better to use antennas that assign a different RET port (electrical tilt) to 4G and 5G.So, Aglocell utilizes AI-driven image classification algorithms to detect if cells are overshooting and downtilts to improve SINR and reduce overshooting. ![]() The distance is something that is usually fixed as 5G/4G sites mostly use the previously deployed network. Sites that are too close to each other will have a higher tendency to interfere with each other and will require aggressive down-tilts to limit overshooting. Let’s check some of the factors that impact SINR So, the first thing Aglocell verifies is the SINR of each cell in the network. If the SINR of a network is bad, then that puts a limit on the throughput gain that it can achieve. The most basic and common factor that Aglocell utilizes to control spectral efficiency and throughput is SINR (Signal to Noise and Interference Ratio). Alglocell automates spectral efficiency optimization utilizing various factors that impact spectral efficiency and 5G/4G throughput optimization. ![]() If the number of bits transmitted in a subframe (time) over a specific number of Resource Blocks (frequency bandwidth) is high, then it will correspond to higher throughput and higher spectral efficiency. It is proportional to throughput as the throughput is also bits per time transmitted in a certain bandwidth. Spectral efficiency is simply the number of bits transmitted over a frequency bandwidth in a specific time and is measured in bits/s/Hz. ![]()
