Introduction to kunke Network Access Technology

The introduction to the network access technology of yunke has different access methods for different networks. What we need to do today is to give you a better understanding of Ethernet Access and wireless network access. I. Ethernet Access 1. With the increasing number of networks, Ethernet access is the most common method for every enterprise and household. It has already reached 0.1 billion million users worldwide. Currently, 30 million new users are added each year, the main reason for adopting Ethernet as a means of access for enterprises and institutions is that there is already a huge network base and long-term experience.

Currently, all popular operating systems and applications are also compatible with Ethernet, with advantages such as high performance and price ratio, scalability, easy installation and activation, and high reliability. 3. The same Ethernet access mode is very suitable for the IP network, and an important breakthrough has been made in technology: LAN switching, large-capacity MAC address storage, etc, capacity is divided into 10 Mb/S, 100 Mb/S, 1000 Mb/S three levels, can be upgraded as needed, 10000 Mb/S Ethernet technology is coming soon. 4. Dedicated full-duplex fiber connection without collision, which can greatly extend the transmission distance of Ethernet and meet the application needs of access networks and man networks.
2. Wireless Access 1. Wireless access can be divided into mobile access and fixed access. mobile access can be divided into high-speed and low-speed access. High-speed mobile access is generally a mobile communication system, low-speed access is used for WILL, PACS, and PHS. 2. Fixed access uses wireless access from switching nodes to fixed user terminals. It is actually a wireless extension of the PSTN/ISDN network, the access methods include microwave one-point multi-access, fixed applications for mobile access in cellular areas, wireless user loops, and satellite VSAT networks. The fixed wireless access system provides narrowband services, basically telephone services. Www.2cto.com 3. LMDS is composed of multiple hub senders. Each sender communicates with a fixed user in the service area through a multi-point wireless link. The coverage areas are reselected from each other, the coverage area of each cell can be divided into multiple sectors to provide specific services in this sector as needed. This modular structure makes network resizing flexible and convenient. 4. In order to reduce device costs and improve quality, LMDS can provide all services from TV distribution and telephone to full-exchange broadband multimedia services, however, the most favorable opportunity is to provide interactive TVs and high-speed data. LMDS not only provides Internet access, but also can be used to interconnect local networks. 5. The LMDS system is still in the field test phase. Whether the LMDS system can be developed depends largely on whether a low-cost 28GHS Transceiver can be developed, the amplifier in this band needs a single-chip millimeter wave integrated circuit based on the arsenic technology, which is not easy to achieve low cost and high performance. Broadband fixed wireless access technology represents a new development trend of broadband access technology. It features fast connection, simple maintenance, and low cost.
