NEOsite dual-mode small base station solution Data and voice services

In 2016, the mobile communications industry opened a new chapter. After many years of operation by operators, the coverage and capacity level of China's 4G TD-LTE network have steadily increased. The accompanying application of various data applications has mushroomed, and users' demands for network quality have also skyrocketed. In particular, the forthcoming 4G Voice VoLTE service, which is about to be launched nationwide, places higher requirements on the quality of mobile networks, especially indoor coverage networks.
At present, in order to fully protect the smooth development of 4G services, operators have gradually stopped investing in 2G services. However, it cannot be overlooked that there are still a large number of 2G existing users in the existing network, and a large number of 4G users' voice services still have to go through 2G. Even if VoLTE is already in commercial use, there are still a large number of 2G users who need to use the GSM network. It takes at least 2 to 3 years for the terminal to be replaced. How to ensure that the services of these voice users are not affected is a difficult problem for operators. In many places, temporary strategies for freeing busy 2G equipment have been adopted. However, in many indoor scenarios, the lack of 2G coverage makes voice services difficult to meet user needs.
Faced with the dual demands of data services and voice services, Datang Mobile's NEOsite solution provides operators with effective and fast solutions.
As early as 2012, Datang Mobile has been engaged in standardization and research and development of integrated leather base stations. The NEOsite solution is Datang Mobile's many years of dedicated work. As an integrated leather base station solution, NEOsite products are compact in size, easy to install, and support plug-and-play network cable, which is more conducive to rapid networking and deployment. This product is especially suitable for blinding and reheating indoor coverage scenes. At the end of 2015, with its excellent quality and reasonable price, Datang Mobile's NEOsite solution successfully won the bid for China Mobile's first integrated leather base station assembly and procurement project.
However, although the single LTE mode can make up for 4G coverage of indoor coverage, for voice services, it is still not possible to solve the problem of using VoLTE services or switching to GSM networks. In order to solve the voice demand at the same time, dual-mode base stations are imperative.
NEOsite products have foreseen this trend since the beginning of the design. An external jack is reserved at the backplane, and an external module can be quickly inserted to realize the function expansion of the base station equipment. As a separate external unit module, GSM can implement a separate 2G source function. The entire module is equivalent to an ultra-small GSM base station. The operating frequency band is optional in 900M and 1800M, and supports 2 GSM carriers, providing voice services for 12 users. Only by inserting a GSM module into a small base station, a gorgeous transformation from a single-mode LTE small base station to a 2G+4G dual-mode base station can be realized.
This rapid mode expansion method is particularly suitable for upgrading the use of existing network equipment, without the need to return the equipment to the factory, online upgrade can be achieved, a set of dual-mode devices can be installed in a few minutes.
The dual-mode small base station maintains the excellent quality of the NEOsite's small form factor. With the addition of the GSM module, the volume has only increased by 0.48L. In addition, the new GSM mode is basically “zero impact” to the original LTE mode, and the two modes can achieve multiplexing of multiple functions:
传输 Transmission reusable - GSM multiplexes existing transmission resources of the small base station and accesses dedicated 2G gateways;
供电 Reusable power supply - After adding GSM module, POE+ power supply and DC power supply are still supported;
网关 Reusable gateways - Datang Mobile's NFV converged gateway supports 2G and 4G function merge settings, and also supports separate settings;
网 Network management can be reused - Datang Mobile's network management system supports the alarm, configuration, and security management functions of the GSM module.
Datang Mobile's NEOsite solution has been focusing on improving the indoor coverage of wireless communication networks and making unremitting efforts to build a network with high value and high user experience. For operators, on the basis of the existing single-mode LTE base station, only a small amount of changes are needed to support the simultaneous support of the GSM system, providing a strong guarantee for indoor voice coverage.
