"Intensive" experience in Hong Kong

For CSL's network upgrade with China Unicom to deploy WCDMA HSPA + what different focus, Li explained that Hong Kong's slate tablet pc geographical features are generally smaller, densely populated, so the network density zone boundaries is not obvious, are often full of new technology unified network upgrade deployment. And relatively speaking, the mainland is also on the rise of 3G development, user data size and throughput of the whole network has not yet peaked. Unicom HSPA + upgrade is based on the initial 64QAM technology that can quickly enhance the existing network of HSDPA speeds, and minimal impact on the network, frequency resources are not affected.

He also mentioned that, CSL based on its slate tablet pc 900MHz, 1800MHz, 2.1GHz, 2.6GHz band wholesale android tablets pc coexistence situation, using a 4-band antennas, and other new equipment to solve the dense areas of network coverage, which part of the site using a broadband antenna, which can save days of face resources, reduce rents, but also reduces the difficulty of installation works, but the broadband antenna of the antenna than the average cost is slightly higher. In mainland areas, the day side than the Hong Kong resources better, "to enhance the network coverage rate depends on the signal strength and interference level for antenna system can be considered high-gain antenna, RRU nearly antenna and multiple antenna receiver technology, to reduce losses, increase coverage, improve the radio link quality, to achieve the goal of enhancing the network rate. "


Two years ago, the impact of the large slate tablet pc flow of data services to the Hong Kong operator CSL network upgrade to HSPA HSPA +, followed earlier this year opened LTE. CSL deploy HSPA + in the frequency of use, especially in dense urban network deployment device deployment has accumulated some experience. It is involved in the project, said Jiang Li, ZTE, CSL had to upgrade to HSPA + network SDR-based base station, its original three-band four networks were integrated, and the whole network using IP-based flat structure.
