In other words, it can be defined as the net data rate in bits per second (bps) divided by the bandwidth in hertz. Net data rate and symbol rate are related to the raw data rate which includes the usable payload and all overhead. Spectral efficiency usually is expressed as “bits per second per hertz,” or bits/s/Hz. In this case, when the traffic is not high but utilization is still high Aglocell optimizes SINR.Īglocell utilizes AI-driven algorithms to improve spectral efficiency up to 19.5% or more by automating the optimization of numerous factors that affect spectral efficiency including the above mention factors.What do you think of when you hear word “spectral efficiency?” The answer will come, it has to do with the amount of information that fits in a given channel bandwidth or one just say how efficiently can that piece of spectrum be used to transmit information.īefore we digging into the details of spectral efficiency, it’s important to understand that there is a hard limit to how much data can be transmitted in a given bandwidth and this limit is well-known as Shannon-Hartley Theorem and commonly referred to as the Shannon limit. This is usually caused due to low signal quality as the users with bad SINR will take a lot RBs at a lower modulation. Sometimes, Aglocell has found the actual traffic volume is not that high but the utilization of the cell is still very high. Aglocell tunes cell reselection or mobility parameters to optimize load. So, if the load increases above a threshold, then Aglocell offloads the congested carrier and shifts the load to an uncongested carrier. For neighboring cells, such power is considered interference. As the load increases, the power per Resource Element increases which will result in higher aggregate power in the area increasing the RSSI. Higher the load, the higher the interference to the neighboring cells. 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.
