broadband wireless network technology ppt

Nic is an important part in the configuration of a wireless broadband router, and also affects the performance of the Wireless Broadband Router. Generally, you can use wireless Access Point (Access Point) and Wireless

Mobile communications in the world's great success, driving the development of a variety of broadband wireless technology, the world's wireless technology is stepping into the broadband universe. At present, 3G

Access network refers to the "user interface and Business node interface between the implementation of the host function of the entity." Access network basically includes transmission system, multiplexing equipment, user/network interface, digital crossover equipment, etc., usually access network transmission system ac

network, that is, the so-called "last kilometer." Narrowband access mode has become the main bottleneck of high-speed Internet and broadband service development. At present, it is urgent to provide high-speed broadband access technology for user access section. Compared with other access technologies,

defined it in 2 ~ What is the 802.16e Distribution frequency in the 6 GHz band. The ITU is also discussing the future frequency of broadband wireless access, coordination issues with other businesses, such as satellites, and international roaming issues. Theoretically, WiMAX wireless broadband

This paper first introduces the general situation, system composition and network structure of LMDS technology, then discusses several typical applications of LMDS system in the field of access, and finally, combining the experience of constructing LMDS test or commercial system at home and abroad, some problems needing attention in constructing LMDS system in our country are put forward.Application of LMDS

speed can reach N × 64kbit/s to 2 Mbit/s, or even up to 155 Mbit/s, and the bandwidth in the working band must be at least MHz. LMDS is a new technology, the Application of LMDS in Internet and high-speed data communication should be paid attention to by people in the industry ｡ Broadband Wireless Access Network Devic

Now the wireless network is more popular, notebook mostly with wireless function, computer screen display to find a wireless broadband connection, but wireless network is not connected,

The goal of network development is to achieve better performance, wider bandwidth, and lower costs. I am wondering if I want to introduce a broadband wireless access technology and orthogonal frequency division multiplexing (OFDM). The birth of this technology will bring new

circuit service may be different in different segments, so the delay is not fixed. In addition, because the wireless network has different characteristics, DOCSIS is used for broadband wireless access technology. The existing DOCSIS standard limits large-scale

The broadband wireless access technology represents a new and noticeable development trend of broadband access technology, not only the network opening fast, maintenance simple, the user is more dense when the cost is low, and cha

, such as: Conference Room, Hall, large bay and so on. This program can also be applied to hotels, trade fairs, temporary venues or large storage supermarkets.D-link Wireless Application Solution topology MapFrom the perspective of the entire project architecture, this scheme can not only realize the flexible, mobile, low-cost and easy installation of other wireless solutions, but also make the whole

With the rapid development of wireless network technology and the rapid growth of Internet access requirements, wireless broadband services are booming, and the demand for high bandwidth and high coverage is getting stronger and stronger. The 11n

MIMO technology can be used as a bridge to connect old and new wireless technologies, so that the two can develop and integrate harmoniously. So it is already an important technology in the next generation of wireless broadband mobile communication systems. The following wil

How can we make the home network more secure? In particular, users who use wireless broadband routers often experience virus attacks, network users, and account theft. In principle, we introduced the security threats faced by wireless home networks and how to reinforce the s

First, the introductionThe broadband access network is regarded as the last kilometer of the information superhighway, which will become the key point of the future national information infrastructure development. At present, there are several broadband access modes, such as optical fiber access, XDSL, broadband fixed
