card double stay? It is obvious that any version of Huawei Mate S is supported by dual SIM cards, the dual SIM card supports Nano-sim, one of which can also be plugged into microSD, and the maximum 128GB expansion is supported. In other words, Huawei Mate S and Glory 6 Plus and Huawei P8 similar, using the hybrid technology. Huawei Mate S Dual 4G network support situation: 4G Network mode Mobile 4G (tdd-lte)/Unicom 4G (Fdd-lte) 3G Network Mode Mobi

"WCDMA only" is selected. Note:1.GSM/WCDMA (Automatic mode) can be switched automatically in 2G and 3G mode. When the 3G network signal is not good, it will automatically switch to 2G mode. 2. To achieve 3G Internet access

The third Generation Partner Program (3rdGenerationPartnershipProject, or 3GPP) is a standardized organization established in December 1998. Currently its members include European ETSI, Arib and TTC in Japan, CCSA in China, TTA in Korea and Atis in North America.The goal of 3GPP is to develop and implement a global (third-generation) mobile

1.3G Requirements for the transfer network WCDMA, CDMA2000 and TD-SCDMA as the three major standards of 3G, the main difference is the air interface part, the network's logical structure is basically the same. From the perspective of the transport layer, the three standard network structures are similar, so the requirements for the transport network are similar to each standard. For example, cdma2000ev-do is equivalent to the WCDMAR99 version of the

systems that can be upgraded from cdmaone to smooth. The route of its evolution is Cdmaone--cdma20001x--cdma20001xev. Another mainstream of the third generation of communication technology is the second generation of GSM standard developed by the WCDMA technology, because GSM uses TDMA (time division Multiple Access) modulation mode, and WCDMA uses CDMA (Code Division Multiple Access) modulation, its air c

specific sites. We are trying to separate the importance of the address structure from the Address Allocation program. In this way, the routing table of the Border Gateway Protocol is reduced. LISP supporters say this technology allows enterprises to easily switch carriers without getting new IP addresses, because even if the location information changes, the recognition function remains unchanged. LISP will be able to provide enterprises with additi

with the traditional SR and BRAS, the full-service router technology greatly improves the processing performance, service provision capability, high-quality QoS service capability, and security protection capability, it helps telecom operators build an IP bearer network that comprehensively carries voice, data, video, and mobile services in the 3G era. Evolving in a higher direction With the increasing number of broadband users and services of operators and the IP address of telecommunication n

cash machines. Multi-line smart routing to solve the problem of cross-carrier network interconnection At present, large-scale VPN networks are often cross-carrier. However, the bandwidth for interconnection between domestic carriers is too low, resulting in low access speeds between different carriers, seriously affecting the VPN application effect. As a leading VPN and network security R D provider in Ch

1. Introduction Automatic Switching Optical Network (ASON) technology has been accumulating and improving after years of development. For most carriers in China, Traditional transmission networks already have a large scale. How to introduce ASON technology more rationally to achieve stable evolution of transmission networks is the main issue discussed in this article. 2. Introduction of ASON technology At present, the transmission network is basically

reliable connection, the second connection mode is better than the first one if conditions permit. First, it may be different carriers, so that different carriers can support each other. Or, if you already have an ADSL connection, you can use wireless access or cable modern to connect to the new line. Wireless Internet access service is also a possible option. For domestic users, cross-network bandwidth is

, and the random access process selects only one of the NZC-length sequences sent to eNB. 4. Interface mappingFor Pusch RB, each sub-carrier accounts for 15K of bandwidth, so 6 RB (12 sub-carriers per RB) is a total of 1.08M of bandwidth. In particular, the RB for the Prach channel, each sub-carrier is 1.25K, so there is a total of 864 sub-carriers. When the UE chooses a certain preamble, it is mapped to 83

phone products to meet the needs of carriers ." Yu Chengdong did not shy away from saying that he was about to cut down more than 80% models in the second half of the year. He said that Huawei relied on operators to sell mobile phones, which led to a lack of distribution channels. According to reports, in 2011, 65% of Huawei's mobile phones were sold by carriers, and the remaining 35% were sold by retaile

organizations, developed 2G, 3G, 4G ,..., Or even nG standard specifications. They have made great efforts in Baseband Communication (corresponding to the BP function of mobile phones) and are promoting the development of the entire industry. The basic difference between smartphones and functional mobile phones is AP + BP (please refer to [5]). The advantages of carriers and traditional communication vendors are BP, BP mainly supports voice calls, te

developers. By providing an urgently needed universal platform for wireless data application development and execution, brew has become an engine for promoting the growth of the entire industry. Developers can write applications faster, quickly enter the mass market, and ensure that benefits can be obtained. OEMs can launch new devices more quickly by doing a very small amount of internal development and integration work. By providing a wide range of applications, content, and services,

For example, the previous time was in more than 20, the word Baidu index is very high, I just want to push it to the first page, every day to give it more to do some outside the chain, the result, not a few days no rankings, ran to 100 away, only to suddenly realize that I was too pushing the word, leading to excessive optimization, Below I think what should do to make Baidu think is natural optimization, the fi

As an application-level programmer, there are a few more skills. Multi-skill and no body pressing2. What is 3G?3g is the third generation mobile communication technology, refers to the support of high-speed data transmission of cellular mobile communication technology. The 3G service is capable of transmitting both sound and data at a rate of

In the past few days, we have been testing telit's 3G module uc864 and encountered the following problems. Fortunately, we finally solved the problems through our own tests. Problem 1: When querying the network registration type, the result value is always 4-indicates an Unknown network or an unregistered network. Solution: When you enter at # psnt? When querying the network registration type, the system needs to obtain the current network results and execute the command response for a longe
