HSDPA (High speed downlink packet access) is used to realize high speed downlink data service of WCDMA network, which can make the downlink data rate reach 8~10mbps, which is regarded as the main solution of the 3G era. The data rate can reach 20Mbps in the HSDPA system with multiple and multiple out (MIMO) technology. The emergence of HSDPA has aroused great concern of the industry. As the following evolution technology of WCDMA system, many key technologies in HSDPA are similar to CDMA20001XEV

reached 108, WCDMA style has been a relatively many improvements. At present, the commercial system, from the WCDMA angle is mainly based on F4, cellular mobile camp including broadband access, different camps competition between the comparison, but also to promote the 3G technology and standards continue to develop. CDMA2000 's camp is in the position of comparative advantage, as 1X itself can provide a user rate of up to 80K. WCDMA itself and the E

1 Introduction With the continuous improvement of people's living standards, people pay more attention to health and environmental protection, which objectively makes it more and more difficult for wireless cellular network operators to find suitable cellular sites. For mobile operators, especially the new mobile operators, in the early stage of a network, hope to use a wide-coverage, low-density density o

demand but also saves the investment, the degree of network planning is inseparable with the accuracy degree of the propagation model. In the second generation of digital cellular mobile technology GSM, several common propagation models recommended in GSM code are the empirical formulas that we have already known and widely used in engineering practice. It includes the Okumura-hata, Cost231-hata and the Walfish-ikegami formula suitable for the honey

Core location is a framework for providing device locations in the iOS SDK. You can use three techniques to get a location: GPS, cellular, or WiFi. In these technologies, GPS is the most accurate, and if you have GPS hardware, the Core location will use it first. If the device does not have GPS hardware (such as WiFi iPad) or if it fails to get the current position using GPS, the Core location will be back and then choose to use

IntroducedNowadays mobile devices have become a part of our lives, and many of us are inseparable from them. When these mobile devices are connected to the Internet, the power of mobile devices will be endless. We can send data to users at any time and place. Typical mobile applications are developed on the server using WML, WMLScript, and Wbmp.For dynamic WML applications, developers can use ASP, JSP, PHP, and so on. Mobile devices include cellular p
