Analysis of demand and application of microwave trunk access for ISP group users

The Computer network communication protocol is TCP/IP;
Provide at least >64kbps data communication rate;
Network isolation is implemented by the local router;
Establish a Level two network, select the users with better geographical conditions to establish a secondary center to meet the requirements of user access within the metropolitan area;
The omni-direction antenna can be used in the two-level center to realize the point-to-point communication mode in a certain coverage range and improve the performance-price ratio of the whole access system.

  

ISP group user microwave trunk access Level two network description

The secondary network divides the first star structure into two levels, which brings the following benefits to the transformation of the transmission system from the large area to the Community system:
* The first level center to the two level center can use the directional point-to-point connection, guarantees the communication channel the speed and the reliability;
* Flexible expansion of data throughput at tier two centers based on specific needs
* Two-level center can generally use point-to-point access to users, save investment
* The Community system makes the frequency use efficiency greatly increased

* Connect a wired hub on the Ethernet interface of the router on the ISP network control center LAN to provide multiple LAN interfaces, connect several wireless access point ap-10d on the hub, and connect a 24dBi directional antenna.
* A wired hub is also connected to the Ethernet interface of the two-level central LAN router, providing multiple LAN interfaces and connecting a ap-10d and a wireless bridge wb-10d, where wb-10d connects a 24dBi directional antenna and a network control center connection, The ap-10d connects a 6dBi omnidirectional antenna as a relay.
* Connect a wireless One-port adapter sa-10d and a 24dBi directional antenna on the client LAN router interface, and connect the network control center of the ISP with the two-level center as the relay station.
