While the whole world has been focussing on HSPA+ and LTE small cells, a recent press release from Ericsson told us about GSM based 'City Site' deployed in Nanning. From the press release:
Currently, China’s urban construction is in full swing, and its mobile network coverage is rising. In the increasingly crowded urban environment, however, ensuring the quality of mobile-network coverage has become a problem.In order to meet this challenge, Ericsson has launched the City Site integrated solution, and successfully applied it to China Mobile’s GSM network in Nanning, Guangxi. The City Site, which has been deployed with the standard RBS6601 base station, has an integrated Omni Antenna, which only covers a small area and is, therefore, easy to deploy. It could also be launched with just access to power and transmission cables.According to the test of the live network, the City Site has effectively met the capacity and quality needs of network coverage, as well as ensuring excellent user experience.In addition, the City Site has also been equipped with functions such as electronic advertising, clock and public information inquires with touch-screen technology. Operators now can not only enhance the mobile coverage but also launch more value-added services via the City site.
The City Site has fewer limitations for site selection compared with standard radio base station, as it can be deployed in crowded areas, and is suitable for a variety of places, such as railway stations, business districts, schools, parks, squares, and main avenues. While enriching the base station building approaches, it provides users with an excellent and satisfactory network experience. Ericsson will continue to cooperate with China Mobile to apply the City Site more extensively through further research.
Fierce Broadband Wireless also provides additional details on this as follows:
Ericsson's small cell, called City Site, consists of a 13-foot-high panel with a base station and an integrated multidirectional antenna. China Mobile is testing a GSM version of the City Site, but Ericsson says the small cell can also support 3G and LTE. Depending upon the frequency band and coverage and capacity requirements, the City Site can cover anywhere from 50 meters to 200 meters.So the focus is on Voice/SMS for the time being but depending on the success we may see TD-SCDMA or LTE based City Site's available soon.
