MediaTek's products in Taiwan, China, are widely used in mainland mobile phone companies and mobile design companies because of the integration of more multimedia features and lower prices. More because MTK's completion rate is higher, basically in 60, so that mobile phone manufacturers to get mobile phone platform is basically a semi-finished product, as long as a slight processing can be shipped on the shelves. This is the most important reason why many Shanzhai phones use MTK. Below we will t

Mb/s in 4psk mode. In the latest HomeRF2.x, WBFHwidebandfrequencyhopping technology is used to increase the frequency-hopping bandwidth, from 1 MHz to 3 MHz and 5 MHz, and the frequency-hopping rate also increases to 75 s, its data peak value is also as high as 10 Mb/s, close. the IEEE802.11b standard is 11 Mb/s, which can basically meet the needs of home broadband communication in the future. 9.

In the next few years, carriers will use SDN technology to enable their man and wan to carry cloud services. Therefore, they need a multi-layer SDN architecture to optimize the routing network and transmission capabilities, this increases the flexibility, scalability, and efficiency of man and wan. Preface Cloud Computing technology has completely changed the design and operation of data centers (iDCs. SDN technology introduces this on-demand concept

There are many access networks in China, and wireless access networks are also widely used in people's daily lives. So I studied the problems in the development of access networks. I would like to share with you here, hoping to help you. First, the current user experience before the integration of fixed and mobile services and networks, whether it is mobile or fixed services, their businesses require multiple contracts, multiple numbers, multiple user data files, and multiple bills. At the same

research, technology development and standards began in the 80 's, the International Telecommunication Union (ITU) officially named as the International Mobile Communications (imt-2000,international mobile Telecommunications in the Year 2000). The European Telecommunication Standards Association (ETSI) calls it a universal mobile communications system (UMTS,UNIVERSAL Mobile telecommunication systems).3G is the most basic feature of intelligent signal processing technology, intelligent Signal Pr

Now, Iot is quite popular. Which affects the on-board industry. Recently, many wireless communication modules were used. In the early days, the GSM (GPRS) module was used. Currently, the 3G module is used more than TD. The 3G module generally uses a USB interface (usually with a serial port at the same time). In wince, the driver is required to connect the 3G module through USB. DriverProgramAll are provided by 3G module vendors. We are only responsible for packaging them into the wince OS i

existing DSP operation speed limit can only do 240km/h; second, the base station coverage radius within 15km, spectrum utilization and system capacity can reach the best, in the user capacity is not very large area, Base station maximum coverage up to 30-4km. Therefore, TD-SCDMA suitable for use in cities and suburbs, both in urban and suburban areas do not affect the actual use of these two deficiencies. Because in cities and suburbs, speed is generally less than 200km/h, urban and suburban po
