Nowadays, more and more schools have the need to build up their own Canteens. When students waiting in line to get their food or eating, they would use smart phones to surf the internet and some may even use laptop. So if school could deploy wireless networks that would improve satisfaction of the students. What’s more, school may also publish announcements through wireless network.
What are the basic needs of school canteen wireless network?
A school canteen wireless network should meet the following needs:
1、Wireless network could cover all the store without any dead corner.
2、Auto switch access point when students are moving, network keeps fluent.
3、It is crowded when students eat lunch, so it requires that AP could support more clients and Load Balance feature.
4、Concise layout, good looking, PoE supported, and easy to install.
5、It needs all APs could be managed & configured uniformly. And just use one controller could monitor the whole APs and give a feedback.
What kind of solution can meet the needs of school canteen wireless network?
Topology
Tips for deploying this network topology:
When starting to deploy the wireless AP, the positions to deploy the AP and the amount needed depends on the signal strength and the interference. The result is always different due to different environment, so it is strongly suggested to deploy the AP and adjust the transmit power and signal channel after a professional field measurement. Normally the three points below should be mainly considered:
- Transmit Power and Coverage
The coverage of an AP is limited, but we can fine adjust it by the transmit power. As the limitation of the lobe pattern of the celling mount AP, one AP can cover 10-14 meter. While a real coverage deployment should be decided after the field measurement.
- Signal Channel Distributing
Another factor must be considered in wireless network deployment is channel collision. All over the 13 channels in 2.4GHz frequency range, only 3 channels won’t overlap each other, which are channel 1, 6, 11. To avoid channel collision, we should choose channel 1, 6, 11 and place them alternately.
- Clients number
The AP should have the ability to carry all the clients in its coverage in the dormitory.
One of the schematic diagram shows as below:
What are the highlights of this solution?
- Easy to deploy
The EAP is ceiling mount designed with beautiful appearance. It supports PoE standard so that could be deployed easily.
- Auto roaming
EAP Controller could manage many EAPs with the same SSID, clients would switch to the other EAPs automatically when they come near the other EAPs.
- High availability
Support Load Balance that could restrict the maximum number of the clients connected to one signal EAP to avoid overload; Support Band Steering that could lead the clients connect to 5G network. Support Airtime fairness that could improve the whole network throughput.
- High development
Support radius, portal, voucher authentication and so on. And it could work with the external portal server and external certificate server.
- Easy to manage
No need to buy the expensive hardware AC. All the EAP could be centralized managed by a free EAP controller software. All the EAP status can be monitored on the web GUI of the controller.
