In the mobile Internet and the widespread popularity of intelligent terminals, the network hot spots and blind spots need flexible solutions to improve coverage. 4g cell phone jammer Given the increasingly difficult siting and increased construction difficulty and cost of base stations, base station equipment miniaturization, low power, controllability and intelligence into a trend. 4g cell phone jammer
In this regard, the industry chain coincidentally this year launched a series of deployment flexibility, miniaturization of base station equipment and technology, such as Shanghai Bell lightRadio base station can be decomposed into multiple components, and the functional modules distributed antenna network and cloud architecture , and its upcoming pre-commercial products; Nokia Siemens Networks FlexiRace its out on a small road in a revolutionary step, a compact design, with a more intelligent and expansion options, which can be used to build a new generation of active antennas and future micro and ultra-micro cell.
The second half of the LTE small base stations, antenna devices are also springing emerged, ZTE launched the integration of LTE has been commercially available micro-standing internationally, compared with traditional distributed base station, its equipment hardware costs will be reduced by half. Datang Mobile for TD-LTE also launched an integrated baseband and RF integrated small base station products.
Zero site characteristics are reflected
"Demand is built," the 2G / 3G network data traffic surge in pressure, a few years ago with the emergence of low-cost miniaturized base station concept, but it was not for the traditional telecom equipment vendors touted because of First, the traditional telecommunications infrastructure is centralized in the central management of the main equipment suppliers to provide very large base station equipment, network bandwidth solutions to carriers, so the network management easier. The base station towards miniaturization and low cost, not only will improve network management more difficult, it will result in changes to existing profit model. 4g cell phone jammer
And now, under the multiple factors driving the development of small base station / home station has been unstoppable.
Volume, transmit power, the characteristics of different application scenarios division, currently mini / micro base station equipment into Micro, Pico, Femto other types.
Chinese communications technology business unit Feng Bin, director of the antenna of the correspondents said: These micro / small base station allows operators to zero sites deployed in dense urban new cell, such as Pico are indoor cellular base stations used in shopping malls, subway stations and airports and other enclosed public environments; Femto is based cellular base station house, used to implement residential interior 3G / 3.5G / LTE network coverage. 4g cell phone jammer
Pico, Femto application characteristics exist differences
Among them, for Pico deployment as well as "mobile LAN," the scene. According to the manufacturer who explained that the mobile LAN market because of lack of resources or transmission signal generated poor indoor coverage, such as islands and other transmission resources are scarce areas. For this type of mobile LAN, network equipment manufacturers have begun to launch PicoBTS, connect the access mobile operator's core network via broadband users. It supports satellite transmission, ideal for covering the islands and boats coverage and emergency communications, etc., can also be used to build enterprise, campus private network. 4g cell phone jammer
This year the number of global 3GFemto 3G base station deployment has exceeded the macro base station. In China, China Unicom, based on Femto's "3G Inn" operations launched from the end of 2009, after nearly two years has been commercial trial. China Mobile's TDFemto pilot has also been award results. From the end of last year to now TDFemto pilot cities has further expanded from Shanghai to Guangdong, Zhejiang and other four regions in the pilot China Mobile also launched a dual-mode TD-LTE & TDFemto research.
According to one of the engineers involved in vendor Datang Mobile, said, TDFamto commercially after the pilot after a year of time you can achieve large-scale applications, but considering TDFemto overall operation, management, networking, and evolution to TD-LTEFemto, operators Manufacturers also developing an overall deployment plan.
"Technology in itself is not an obstacle TDFemto scale applications."
