4G Cell Phone Jammer To address these challenges, a small base station emerged. Small base station transmit power is relatively small, can be an effective complement macrocell coverage. The cost of a small base station is low, its base construction costs, management and coordination should be much lower than the cost of a macrocell base station. These combined factors contributed to the emergence and development of small base stations.
Small base stations seem small, but R & D is not easy. When talking about the key technical advantages of small base stations, Guili considered significant technical characteristics of small base stations are small, flexible access, through ADSL access at home has obvious advantages transport and equipment miniaturization, simple installation and maintenance . 4g cell phone jammer
Further, the macro base station requires a lot of complex functions, for the purposes of the small base station is often not required. When talking about the main purpose of the small base, he noted, the small base station is mainly used to eliminate coverage holes of the wireless signal, and high-capacity data services to be supported. 4g cell phone jammer
Small base station deployments need to address issues such as property ownership
For actual deployment highlighted the advantages of small base stations, as well as technical problems to be solved, Guili said that the deployment of a small base station property ownership issues need to be resolved first. If the operator by way of the deployment, then the situation is relatively simple. But sometimes, operators will be home base categories of products sold directly to users, which will produce a number of challenges on the operation and maintenance.
In this case, the issue of coordination between the home base stations and outdoor macro base station is difficult to handle. Users will especially femtocell product in what position, the operator may simply can not control, operators very difficult to solve small signal interference between base stations and macro base stations and other issues.
So, when you install a small base stations, operators need to be well coordinated macro base station and the relationship between the small base station, take control of small power station in both "useful", but does not form a conflict with the macro base station and interference range.
Macro base station deployment has been very mature, operators in the deployment of macro base station, when the layout will be carefully measured, analyzed, handle network coverage and coordination problems between the base station adjacent. And due to the small base station has a property complex characteristics, operators deploying small base stations when greater difficulties.
In addition, the development of information security is a small base station can not evade the issue. Operators can better control and manage the macro base station, so from the wireless transmission to a wired system, are able to guarantee a good information security. And there are some small base station is often easy information security risks, which requires the parties attach great importance to the industry and be eliminated.
When talking about the characteristics of small base stations operating model, Guili believes that the current deployment of small base stations is not yet a unified business model, operators can deploy small base stations can also be a small number of ISP user base into the home. In the standardization, the relevant standard-setting work of small base stations are orderly, beneficial to the early realization of the scale deployments.
Currently, TD-LTE commercialization process continues to accelerate, the future of small base stations will play an irreplaceable role in large-scale commercial TD-LTE in. Higher frequencies allocated to TD-LTE, the higher the frequency, the ability to penetrate the worse, especially in the cities, the macrocell coverage in the room will be greatly hindered, so operators must consider the issue of indoor distribution. This makes the deployment of small base stations become the inevitable choice of the operator.
Small base stations and repeaters are not the same. Repeater or macrocell devices, but the frequency of the macrocell achieve "pull away" in order to achieve coverage of the blind, the number of users supported can not be increased. Acer introduced repeater station or deployment scenario, just think of ways to transmit signals farther. But the small base station is not the same, through the deployment of microcells in the macrocell, will effectively improve the frequency utilization, increase user coverage, but it also brings a frequency coordination problems. 4g cell phone jammer
