===== WLAN networks of Rafisa =====
The SSIDs of the Rafisa WLAN networks are RAFISA-WLAN and RAFISA-GUEST. In the RAFISA WLAN, authentication takes place according to [[de:intern:ipa:tp2022:ipa_tp2022|802.1X]]: Based on membership of an AD group, you are connected to the corresponding VLAN after logging in. In RAFISA-GUEST, login is via WPA2-Personal with a password. The password can be requested from the helpdesk. 

===== Connecting the access points =====
The access points are connected to a VLAN trunk on which VLANs 21 (instructor), 22 (student) and 23 (guest) are tagged and VLAN 1 is untagged. The PVID of the port should be 1. Communication between access points and the UniFi controller takes place via VLAN 1.

:!: It is very important that Loopguard for the VLAN trunks is switched off on the switch, as otherwise errors may occur and the port may be deactivated as a result.

===== IP addresses of the access points =====
^ Host name   ^ Switch      ^ Port ^ IP address   ^ Mac address (ETH)  ^ VLAN      ^ Type designation    ^ WiFi Standard  ^ Location    ^
| ap-vd-01   | 172.21.1.2  | 23   | 172.21.1.31  | fc:ec:da:a9:72:74  | 1, 21, 22, 23  | UAP-AC-PRO          | WiFi 4 / 5   | Office |

===== Heatmap of all floors =====
====Software used====
The Heatmapper programme used was developed by Tobias Stähli on behalf of the IFS as part of an individual practical project (IPA) as a final project for the computer science course.

====Signal strength legend Explanation====
The signal strength is shown on the heatmap with colours. Here is a list of the colours, their meanings and which Internet services work well or not well with which colours*:

^ Colour    ^ Colour Meaning         ^ Functioning services        ^ Restricted services        ^
| Yellow     | Very strong signal    | Streaming, surfing, video calls  | None      |
| Orange   | Strong signal        | Streaming, surfing, video calls  | Streaming (4K with 60Hz)       |
| Red     | Moderately strong signal  | Streaming, surfing, video calls  | Streaming (UHD with 60Hz, 4K)  |
| Purple  | Weak signal       | Surfing        | Streaming, video calls       |
| Blue     | Very weak signal  | None      | Surfing, text messages       |
