The most common ways of wireless networking
1. Wireless networkingWith the expanding influence of the industry, radio Module Our business is also constantly spreading, and the development of the market is also gradually advancing. https://www.hkulike.com/
Networking requirements: networking in a wireless way in a local area network to realize resource sharing among devices.
Networking mode: wireless access points are placed in the center of local area network, and wireless network cards are installed on internet devices.
2. Mesh connection
Wireless mesh network is a pure wireless network system, and the APS in the network can be directly connected with each other through wireless channels.
3. Regional-oriented mobile Internet service
Networking requirements: provide mobile Internet service for mobile devices in this area in a large range.
Networking mode: base stations are selected in the area, and wireless access points are placed at each base station to form multiple overlapping cells to cover the area to be networked. If the wireless ad hoc network module is installed on the mobile device, you can enjoy the mobile networking service within this range.
4. Point to point connection
Wireless connection between single computer and computer network
Networking requirements: realize wireless connection between remote computers and computer network center.
Networking mode: install a wireless access point external directional antenna in the computer network center, and install a wireless network card external directional antenna on a single machine opposite to the network center.
Wireless connection between computer networks
Networking requirements: realize wireless connection between remote computer network and computer network center.
Networking mode: install a wireless access point external directional antenna in the computer network center, and install a wireless access point external directional antenna in the remote computer network opposite to the network center.
5. Point to multipoint connection
Multi-point connection with different frequencies
Networking requirements: There are three wired networks: A, B and C. A is the central network, and it is necessary to realize the wireless connection between A network and B network and C network respectively.
Networking mode: a wireless bridge external directional antenna is installed in network A, and a wireless bridge external directional antenna is installed in network B opposite to network A; Another wireless bridge external directional antenna is installed on the A network, and another wireless bridge external directional antenna is installed on the C network, which is opposite to the second directional antenna of the A network.
Co-frequency multi-point connection
Networking requirements: There are four wired networks: A, B, C and D. A is the central network, and it is necessary to realize the wireless connection between A network and B network, C network and D network respectively.
Networking mode: A wireless bridge external omni-directional antenna is installed on the A network, and a wireless bridge external directional antenna is installed on the B network, the C network and the D network respectively, which is opposite to the A network, and the A network is connected with the B, C and D networks at the same frequency.
6. Relay connection
Connection across obstacles
Networking requirements: wireless networking should be realized between the two networks, but there are obstacles between the geographical locations of the two networks, and there is no visible path required for microwave transmission.
Networking mode: By establishing a relay center, find a location where two networks can be seen at the same time and set up a relay point, so that the two networks can establish a connection through relay.
Long distance connection
Networking requirements: wireless networking should be realized between two networks, but the distance between the two networks exceeds the maximum communication distance that can be achieved by point-to-point connection.
Networking mode: establish a relay point between two networks, so that the two networks can establish a connection through relay.
Wireless mesh network can form a broadband wireless communication network covering the city, provide wireless VOIP and mobile broadband multimedia communication services, and also provide metropolitan broadband wireless mobile access services for users in certain industries.
