Brief introductionOver the past few years we have made significant progress in mobile cellular network performance. However, due to the expansion of network latency, many applications have not been improved.Latency has long been a constraint on mobile networks. Although some progress has been made in recent years, the reduction in network delays has not been keeping pace with the delayed growth rate. It is this misalignment that causes latency, not th

Simple IntroductionOver the past few years we have made significant progress in mobile cellular network performance. But because of the expansion of network latency, many applications have not been improved.Latency has long been a constraint on mobile networks. While some progress has been made in recent years, the reduction in network latency has not been keeping pace with the delayed growth rate. It is because of such an incorrect delay, rather than

. It is reported that many companies went bankrupt due to wifi. Not long ago, r wireless also gave up the business. So is the profit of wifi really in crisis? It is undeniable that the commercial use of wifi technology has encountered many difficulties. On the one hand, it is restricted by the limitations of wifi technology, such as its roaming, security, and billing methods. On the other hand, due to the unclear profit model of WiFi, if WiFi is used as a single network, the lack of commercial u

As Google shuts down the base station locator API. Location services have become increasingly hot technology and will become the standard for all future mobile devices (smartphones, handheld computers, etc.). With the rapid growth of the BLS (Based location serices, position-based services) demand, wireless positioning technology is also getting more and more attention. GSM Cellular base station positioning, with its fast positioning speed, low cost (

the last part of this article, you need to download the mapirule source program. I suggest you install the Windows Mobile 5.0 SDK directly. You can find the source program in the wm5.0sdk directory. As for why we do not use the wm5.0 SDK as our development environment, you will find out in the next section. WM 5.0 SDK and simulator are: Http://download.microsoft.com/download/6/0/8/608530c5-7e9a-4032-bf18-92d90b5f4ab4/WM developer Resource Kit. MSI After the SDK is successfully installed, we can

IntroductionAt present, with the development of computer and communication technology, wireless network has become a part of people's life. In the area of commercial communications, with the rapid development of internet-based data communications services and the increasing number of mobile users, a new trend is emerging in the field of information transmission, namely the combination of wireless networks and the Internet. It allows users to access the Internet from anywhere, at any time, to rea

Programmer's life is: encounter problems, especially technical problems, such as the dead, not solve sleep is not good, only solved, steady, just feel practical.This is a spiritual journey from the steady to the last.Because it is to do the technology, and has developed like the summary of the habit, feel spent so much time, so much energy, not summed up, the heart is a bit not practical.Problem Solving problem:1, the battery number does not display the problem2. There is no "

.3. Turn off the wireless network: If you know you will not use the wireless network, you can turn it off to save power. Go to the Settings > WLAN and set the WLAN to "off". Note that if your IPAD supports a cellular network and uses it to access the Internet, using a wireless network instead of a cellular network can prolong battery time.4. Close cellular networ

Array of cells:The cellular array is a special data type of MATLAB, which can be regarded as an all-encompassing universal matrix, or generalized matrix. The elements that make up a cell array can be constants or constants of any data type, each element can have a different size and memory footprint, and the contents of each element can be completely different, so the elements of a cell array are called cells. As with the normal numerical matrix, the

infrastructure: the network infrastructure includes wireless networks, cellular networks, and Wi-Fi. On this basis, the Unified Communication solution is implemented. If the scheme involves switching between Wi-Fi and cellular networks, the mobile controller needs to coordinate this function. Mobile client device: the mobile Unified Communication solution runs through a smart phone. The supplier provides a

When we mention wireless access technology, we will surely think of the wireless networks and mobile communication devices we are using. In fact, wireless access technology has a broader conclusion. What is it? For more information, see this article. I hope you can understand the differences between mobile wireless access technology and fixed wireless access technology. Wireless Access Technology Overview Wireless Access refers to the transmission line between the switching node and the user ter

traditional voice access, it provides the access of packet data, and the analysis of the integrated service access ability of voice and data under the current spectrum is advantageous to the synchronous development of the service and network in GPRS upgrade, thus providing a reasonable theoretical guidance for the planning and design of GPRS large-scale application. (Computer science) Analysis of GSM voice frequency spectrum efficiency under 1 existing spectrum The spectrum efficiency of GSM

A cellular emulator (cellular simulator) is attached to Windows Mobile 6 Professional SDK refresh. MSI ). Cellular emulator enables you to test your application in device emulator. ProgramBehavior in the case of various cellular communication. However, cellular emulator

Terminal mobility) is a recent ETSI approach to the development of personal communications services (PCS) based on DECT technology. CTM allows personal cordless terminals to communicate by using a single business registration registration via a compatible base station based on DECT cordless technology, which meets the requirements of PCs to provide high quality communications, single billing, and unique numbers wherever and whenever. Although CTM does not provide terminal mobility for a typical

The Internet of things wireless communication technology, mainly divided into two categories: ZigBee, WiFi, Bluetooth, Z-wave and other short-distance communication technology, the other is Lpwan (low-power wide-area Network, low-power WAN), that is, WAN communication technology. Lpwa can be divided into two categories: one is working in the unlicensed spectrum of Lora, Sigfox and other technologies, the other is working under the authorization spectrum, 3GPP support 2/3/4g

Google will provide froyo to OEMs and open-source communities in the coming weeks. 　　1. Speed improvement When Google introduced Android 2.2, it put speed first. Google added just-in-time (JIT) in 2.2 to increase the running speed by 2-5 times. The number of Nexus One game frames running in 2.1 is 29, and 2.2 is 41. 　　2. Added e
