8T8R antenna technology can help address challenges for LTE TDD deployment, such as higher propagation loss at higher frequencies and high indoor loss. 8T8R uses 8 transmit and 8 receive antennas to provide improved coverage and capacity over 4T4R. It can boost cell capacity by up to 40% and improve indoor coverage. Huawei's new 8T8R antenna solution supports frequencies from 2300MHz to 2600MHz and 3300MHz to 3800MHz, enabling flexible network configuration through soft split and beamforming functions.
