AIS Thailand carried out its largest subscriber migration from 2G to 3G in 2013 because of demand for 3G capacity, especially in dense urban areas such as Bangkok. To address the demand for improved capacity, AIS deployed Huawei’s dual-beam antenna solution on a large scale for its UMTS 6-sector network, improving capacity by 70 percent and efficiently enhancing coverage.
Huawei says multi-sector networks can improve the spectrum utilization efficiency, but 6-sector networks employ 6 common antennas with a 33 degree horizontal beam width. Capacity improvement is negligible as the side lobe interference becomes a noticeable issue. The increased number of antennas presents an additional challenge to the tower space.
As the provider of both RAN and antenna solutions, Huawei’s antenna adopted a synergistic design that allows for improved side lobe suppression with less interference, enhancing capacity as well as coverage.
Telecom operators can easily deploy Huawei’s dual-beam antenna as the antenna supports two horizontal beams with a width of 33 degrees, meaning the 6-sector network requires only three Huawei dual-beam antennas. Since the antenna width remains the same, these features save much more antenna space for operators, realizing a soft upgrade and capacity expansion in existing 3-sector sites.
