advantages and disadvantages, and analysis of its application in the power system prospects. second, wireless technology introduction (i) The concept of wireless communication technology at present, wireless communication and its application has become one of the most active research fields of information science and technology nowadays. It is generally composed of wireless base station, wireless terminal and application Management Server. (ii) the development of wireless communication

2. OMA protocol2.1 Why the OMA protocol is requiredWith the rapid development of global mobile communication, in order to improve the quality of mobile communication service, meet the needs of people, and solve the problem of data synchronization between different networks, and then realize interconnection, the urgent task is to establish a universal and safe and reliable Unified standards and specifications for easy to operate End-to-end mobile communications. The Global Standardization organiz

Server 2003 in its global network infrastructure. This development is critical because Exchange 2000 does not run on Windows Server 2003, although Exchange 2003 can run on Windows SQL Server. Running Exchange 2003 on Windows Server 2003 offers many additional benefits to exchange, which we'll discuss in more detail later. These benefits enable OTG to begin planning to implement the number of servers in the consolidated global communications infrastructure, which facilitates the design of the Ex

of storage formats and storage locations for their data. To support decision making, improve system performance, or upgrade existing systems, it is often necessary to move data from one data storage location to another. Microsoft SQL Server 2000 Data Transformation Services (DTS) provides a series of tools that you can use to extract, transform, and merge data from different sources into single or multiple destinations. By using DTS tools, you can create customized data

It is often said that one of the characteristics of IPV6 is mobility. So for IP terminals, how to understand the mobility of him? In fact, is IPV6 automatic configuration. Some time ago I was fortunate to have a colleague show me this function, but more questions have emerged. IPV4, such as computers, in the network card to set up automatic access to IP addresses and DNS. Then you can automatically obta

"Digest" WLAN is a rapid development of a wireless access technology in recent years, GPRS is a high-speed packet data exchange technology, WLAN and GPRS technology can be integrated to achieve complementary advantages. This paper introduces the solution to the integration of WLAN and GPRS network, and probes into its authentication, billing and roaming mode. 1 Benefits of WLAN and GPRS fusion Wireless LAN WLAN refers to a computer LAN with wireless media, which consists of a wireless network

OfficeThe use of wireless network Bridge can be used to have a mobile office area at any time. This is useful for companies that need to add office nodes at any time and need a network to connect to an office area. The "Active office" enables these newly added office access points to use all the shared devices, such as the original printers and storage devices in the office, simply to plug in a wireless card.　　 Notebook computer OfficeWireless network technology can provide mobile workers with

The most fundamental reason that we can win the opportunity and respect in the next generation of the Internet is that we build the next generation of Internet as a process of independent innovation, a thorough invention and creation, unlike the first generation of internet just follow up. Because it is a new thing, there is no mature model can copy, copy, must explore their own. Although we started a little late, but we did not blindly follow the United States, but with their own brain to find

certain extent determines the price, the cost of operators will eventually be passed on to consumers. At present, GPRS's core network is to introduce two new network nodes in GSM network structure, they are GPRS Gateway support node GGSN (Gateway GPRS supporting node) and GPRS service support nodes SGSN (service GPRS Supporting Node), there is also a need to increase the Group control Unit (PCU) at the machine station side (Packet). GPRS system adopts the Protocol of Special development, which

wireless access network, which provides the interactive operation between GPRS network and external packet data network. It switches the packet to the correct in-station subsystem (BSS). Its tasks include providing encryption, authentication, session management, mobility management, and logical link management for mobile stations. It also provides connections to databases such as HLR. GGSN is the network joint point between the external packet data N

application for IPV6 address accounted for 1.7% of the distribution, about 1/9 of Japan, the United States 1/8, South Korea's 1/3, accounting for the 16th place in the global rankings, or even less than the number of Taiwan region in China." Why are there so few applicants for IPv6 in our country? According to Li Xiangjian analysis of China Internet Network Information Center, one is not clear about the relevant regulations of Asia-Pacific Internet Information Center. Second, the address appli

equipment appears to be inadequate, Limits the speed and scale of the broadband access market. TR069 defines a new set of network management architecture, including "Administrative Model", "interface", "Management parameters", to a large extent, reduce the cost of transportation of networking products.OMA Protocol WizardI.
