-93 ~ due to floating signals ~ -The signal of 100 dBm will also go through several seconds after the original position is not moved. 2. Experiment verification of optimization parameters According to the results of the current network parameter test, when the current network parameter is configured, the user will immediately switch to GSM after the call is initiated in most areas such as indoor, living room, and study rooms, the test results conform to the theoretical analysis.

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

According to Windows core programming: The X86 operating system provides a maximum of 4 g of virtual memory per program, where 2G of virtual memory is provided to the system (specifically for what to investigate), and 2G of memory is left to the user. What's this 2G of memory going to do? First, you introduce the program memory of the 5 regions: Stack area, heap

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 3G important technology, on the basis of continuous research on 3G experience at home and abroad, 3G requirements and understanding are covered to 3G system-wide require

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

I. Several networking strategies involved in network convergence Although 3G has been under construction in foreign countries, and some of them are in commercial use and quasi-commercial use, the development of 3G in China and abroad is quite different. China's 3G development will be a long-term, gradual, and constantly improved process. Traditional GSM network operators have a wide coverage of GSM/GPRS networks and a large user base, which is both an

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.

network, but also limited the user does not apply for business in the 3G network roaming, So that operators have a firm grasp of the network "right to use." (Computer science) Guiding Principles and implementation strategies Interoperability between systems is introduced because: in the early 3G construction, WCDMA network is difficult to achieve nationwide coverage (but in the WCDMA service area must be a continuous film

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 3G indoor cover. With the 3G pace approaching, 3G network planning in-depth, indoor c
