only transmit data with a single node in one type of RAT, which leads to problems such as insufficient wireless resource utilization, repeated investment in network infrastructure, and further improvement of network capacity. Although HetNet is currently a typical application scenario for improving network capacity, as the number of small sites increases, more and more "community edges" will emerge in the future ", frequent switching, increased failure rate, and reduced throughput of edge users

problem by creating platform-independent programs. A platform-independent program written in Java is easier to write, manage, and maintain than a program compiled with a specific system and operating environment, and is less expensive to secure: Java Architecture guarantees program robustness, and some harmful code does not appear in Java code, such as memory leaks. Java inherently prevents a lot of bugs from appearing, so it also brings another benefit that is unrelated to the network: Improvi

Many of the features in the operating system are not present and need to be done at least two or three steps. Redundant operation of more than one, unavoidably will reduce the work efficiency, if can have a function panel, will common function all put together how good? In fact, the Win7 system has such a panel, we usually use the speaker volume, wireless network connection status and display brightness settings are assembled together.　　This is the Win7 Mobile center.

Because of the business needs, the enterprise's mobility requirements are increasingly high, while the security risks are followed. While solutions to specific security issues have been developed, an integrated approach is needed to leverage the wired network infrastructure in the corporate network to enhance security for WLANs (WLAN, Wireless Local area network). The development of Enterprise WLAN Corporate WLANs have grown rapidly and are no longe

The re-election routing mechanism is also called switching, which is the key part of the mobile network structure. The idea of using a multi-format mobile phone has been accepted by the Global Mobile Communication System (UMTS). Currently provided by GSM to provide a wide range of coverage, using WCDMA macro cell and Microcell to provid

huge consumption, far more than the related income increase. Therefore, it is significant for operators to reduce the cost per bit in order to better meet the needs of users under the premise of guaranteeing service quality. WiMAX is one of the most promising applications. (Computer science) The future of the network will have the following characteristics: IP, broadband, cost more economic, network more convenient management, and a variety of technologies through a unified core network of mut

, low communication range, and no mobility, but low prices. Therefore, they are mainly used for small-range wireless communication, it is defined as a wireless LAN. At present, the Wi-Fi network rapidly develops to crowded places or buildings, such as coffee shops, hotels, airport waiting halls, office buildings, and other places for users to access the Internet. A wireless Mesh network is a new network structure based on multi-hop routing and peer-to

Background With the continuous development of network applications, people are increasingly dependent on the network, which has become an indispensable tool in people's work and life. However, with the changing environment and changing demand methods, mobile has become the trend of network office, and the existing blind spots in wired networks are gradually emerging, such: environment limitations, non-flexible service methods, and so on. As a supplement to wired networks, the wireless LAN Soluti

One of the most important advantages of unified communication is that it provides mobile users with extended communication functions. Mobile Unified Communication is at the intersection of two topics: mobility and Unified Communication. This article will be divided into two parts, respectively studying the functions, technologies and advantages of mobile Unified Communication (UC): the superiority of mobile Unified Communication, the implementation of

terminals, ATM machines, street lamp monitors, and so on are all industry customers' data collection equipment.(4) data transmission and communication between peripheral devices and internal data centers in the industry: Due to the dispersion, mobility, and danger of peripheral devices, the wireless DDN can be used to transmit the data collected by peripheral devices to internal data centers of the industry for processing and implement corresponding

Due to the differences between the fixed network and mobile network in terms of access bandwidth, terminal authentication, and terminal mobility, how to view and solve these differences has become a key issue for IMS-based FMC. The concept and architecture of IMS was initially proposed by 3GPP In R5. As a new domain in the third generation mobile communication, IMS provides multimedia services for users and achieves separation of business and control.

/60. 1/144 of the mobility is poor, and the color separation is not good. Although the price is cheap, we do not recommend you to buy it (especially those who are just starting to make models ). 1/100 can faithfully reproduce the image in the original, and the mobility is greatly improved. The color separation is also possible, and there is basically no need to re-color it. Especially in the later stages, t

that only the complementary use of various access methods can bring economic, reliable and effective. Therefore, it can play an important complementary role in 3G in a specific region and scope. The combination of WiFi and 3G technology will have broad development prospects. Wifi is a supplement to high-speed Wired Access Technology Currently, wired access technologies include Ethernet and xDSL. As a supplement to high-speed wired access technology, Wi-Fi technology has the advantages of
