China Unicom first tested Huawei's 5G Super Uplink on its commercial networks in 2020
China Unicom and Huawei announced last week that they have deployed Huawei's 5G Super Uplink at more than 1,000 5G commercial sites in Beijing. The deployment, which was carried out over...
Midband (or C-band) is considered the “waterfront property” of RF spectrum for 5G. It offers the best compromise between RF coverage and RF bandwidth, and with 100 MHz of bandwidth, C-band can truly enable the highly hyped enhanced mobile broadband (eMBB) use cases. Yet,...
In general, FDD is considered better for coverage and TDD better for capacity
Mobile operators are looking to carrier aggregation (CA), which allows them to use multiple sub-6 GHz spectrum channels simultaneously, as a method of increasing the bandwidth and speeds of their 5G networks....
The physics of time-division duplexing in radio communications means 5G could, in certain frequency bands, struggle to achieve the ultra low latencies it promises. Worse, in some markets, regulatory forces have compounded the challenge with backwards rules about 5G radio operations.
As a consequence, radio...
Sunwave CrossFire Digital DAS Platform Takes on the Challenging Malaysian Deployment
Transit infrastructure, particularly rail systems, are notoriously difficult to connect to cellular networks given the varying mobility conditions, need for underground penetration, as well as the fluctuating capacity demands of both the transport authority...
Although much of the dialogue on 5G spectrum in the US has focused on millimeter (mmWave) spectrum, it is not clear whether the mmWave spectrum is suitable for mobile network deployment in the near to mid-term future.
This is exactly why Verizon is concentrating on...
This paper addresses LTE radio performance in the 3.5 GHz band and how it compares with TDD band 40 (2300-2400 MHz). Experiments have been carried out for throughput Range versus Rate, CQI variation, MCS distribution, and SINR on different path loss. Based on these...
