at t 3g coverage

With the rapid development of mobile communication, it becomes more and more important to solve the problem of indoor cover and capacity, and the micro-cell base station becomes an important means to improve the indoor coverage effect and to increase the special area capacity. The importance of 3G indoor coverage Good network

This paper first analyzes the importance of 3G indoor coverage from the operator's point of view, and then according to the planning principle of 3G indoor coverage, considering the selection of signal source and distribution system, finally briefly introduces the construction flow of

The 3G era has opened the door to China, and end users hope to get faster and better wireless network communication from the third-generation mobile communication network. High speed is a major advantage of the third-generation mobile communication network, but most high-rate services will be used by end users in the static state. That is to say, most end users will use these services in coffee shops, restaurants, offices, hotels, shopping centers, ba

will reach below-14 dB. When RSCP is-105 dBm, Ec/Io reaches-7 dB without pilot pollution. The deterioration rate of Ec/Io is much lower than that of RSCP. B) in the case of total station coverage, the loss of 3G indoor signals is much greater than 2G. The 3G signal in the indoor depth coverage area is weak, but

Differences between conditional coverage, path coverage, statement coverage, and branch coverage in software testing For exampleIf a and B then Action1If C or D then Action2The statement overwrites the weakest. Program All the statements in can be executed once. In the above example, you only need to design a te

Overview of 1.2G/3G Network Wireless resource planning GSM network is the most widely used mobile communication network in 2G network, and has more than 1 billion GSM users in more than 200 countries and regions. China Mobile is currently the world's largest GSM operator, with close to 300 million user capacity of 2G network resources and perfect coverage, 3G ne

has a false start, because from a fair point of view, the real starting line should be "complete all of our provincial capital city 3G signal coverage" time to calculate. In this way, China Telecom completed in April, the fastest speed, the completion of the Chinese unicom in May, the speed of the center, Mobile TD two to be completed in June, the slowest speed. From this we are not difficult to see, three

1 Current 3G situation and important issues that people focus on People's focus on 3G has gone through two different stages. 2001-2002, people's energy is mainly focused on mastering 3G basic technology, through indoor testing and field debugging and other means of technical validation; 2003-2004, while continuing to verify the

Before using the 3G router, make sure that the 3G Internet card is plugged into the computer and can be unplugged successfully. If the 3G card directly connected to the computer can not dial the success, please contact the 3G operator (may be 3G signal

Minimum edge coverage =Maximum Independent Set = | v |-Maximum number of matchesThis is done on the binary graph of the source image.Minimum path overwrite andThe minimum edge coverage is different. N is not required for a bipartite graph.A directed graph of x n cannot have loops, and then a bipartite graph is constructed based on the source image. The construction method is to split points into two parts.
