Before the application
Before choosing an access point, please inform yourself about the WLAN variants offered and the different costs and guarantees involved and then fill out the web form below. All cost centers are eligible to apply.
RHRZ bears the costs
The WLAN infrastructure is uniformly operated by RHRZ.A distinction is made between generally used areas and areas with a limited user group (see table).
- In the future, generally used areas are to be completely supplied with WLAN (eduroam). The focus will be on heavily frequented areas. The RHRZ will finance the expansion of general areas.
- Areas with a limited user group, which are mainly used by a few people, will only be supplied with WLAN or existing WLAN-APs will be replaced if the users request this and the expansion or replacement is financed. The costs will be charged to the applicant after the WLAN-AP has been provided.

Suitability of the end devices
There are WLAN-enabled end devices that do not support 802.1x ("WPA Enterprise") (e.g. projectors, televisions, media boxes, Google Glass...) If such devices are to be used via WLAN, only the "PSK" variant is suitable.

Safety instructions for applicants of variant PSC
PSK stands for pre-shared key, i.e. a key is defined which must be passed on to all users who want to and are allowed to use the WLAN. This key consists of any character string of up to 63 characters. This key is used to gain access to the respective WLAN. The key only has to be entered once on a device when it is connected to the WLAN for the first time. Afterwards, the key can be stored on the device, so that every further connection process can happen automatically and everyone who has access to the device can also use the WLAN. The applicant is therefore responsible for ensuring that the key is only passed on to trustworthy persons or only installed on devices to which only trustworthy persons have access.
The PSK is renewed by RHRZ at regular intervals. Currently, intervals of 12 months are planned, but RHRZ reserves the right to change this. The named contact person will be informed of this change at least one month in advance. In exceptional cases, the PSK can be changed at short notice at the request of the applicant, e.g. if the key has been accidentally made known. In general, RHRZ reserves the right to temporarily block the network access (port) without consultation in case of misuse.

Guarantee by RHRZ
The RHRZ guarantees that a WLAN-AP can be used for at least 5 years ("eduroam") or at least 2 years ("PSK"). If a device has a defect (not caused by the user) during this period, the WLAN-AP will be replaced by an equivalent AP by RHRZ. The same applies if the WLAN-AP cannot be operated during this period for technical reasons. After the 5 or 2 years have expired, however, it is possible that a WLAN-AP cannot be operated any longer, e.g. because no security patches are available, in which case the device must be taken out of operation. Most likely, however, the WLAN-APs can be operated much longer than the guaranteed time.
Important NOTE! Due to the current situation, there are long delivery times for AccessPoints. Our stock is currently exhausted, which is why applications cannot be processed promptly at the moment.
