WLAN – Further Information

The Data Center operates two campus-wide wireless LANs in accordance with the 802.11a/b/g/n standard: one with the network name (SSID) Uni-Mainz and one with the network name eduroam. Both are encrypted and provide increased security. Beside these two, there is also the 'Winulum', which is un-encrypted and therefore not recommended for working or surfing.

Further information about the WLAN networks mentioned may be found here:

Prerequisites for use:

  • A university account or an account at a college or other instituiton that participates in the eduroam network (for eduroam)
  • A wireless-enabled notebook/netbook or other mobile device.

Students and staff of the university of Mainz usually connect to the network eduroam.

Please note: if you are using Windows 7 or any older version of the Windows operating system we recommend using the firewall that comes with that operating system. For those systems we would advise against installing an additional firewall software.

The wireless network named eduroam may also be used by guests from other universities whose home institution participates in the eduroam network.
How to establish an eduroam connection has been → described for a number of operating systems here.

If you have any problems accessing the wireless networks you may look for help in the WLAN-consultation hour at our helpdesk.

Band Width

Currently there are two different types of access points:

Type                    Nominal bandwidth         Real bandwidth

802.11a/b/g          54 Mbit/s                            20 Mbit/s

802.11n               300 Mbit/s                         120 Mbit/s

Nominally, 802.11g supplies a band width of 54 Mbit/s. Transfer rates of about 20 MBit/s are feasible. However, they depend upon the distance from the access point and the number of simultaneously operating stations.

Access Points

There are about 500 access points for wireless connections to the campus network in the publicly accessible buildings (libraries, corridors, seminar rooms, lecture halls etc), as well as in the open on the campuses in Mainz and Germersheim.

Number of Simultaneously Operating Stations

Theoretically, any access point may serve any number of operating stations. However, since stations share the bandwidth (shared medium), the theoretical transfer rate of 54 Mbit/s for one station decreases correspondingly.

Const of Internet Access

The Data Center does not charge for using the wireless LANs described here.

Network Access

The network is accessed via a dynamic DHCP on your own web server. The devides need to be configured appropriately.

Elektric Smog

Very low power, ten times less than a cell phone, about 100 milliwatts (mobile = 1 Watt).
