Wireless LAN - Technology and Configuration

Wireless electronic network - technology and configuration

The Data Center operates a pair of campus-wide wireless electronic network in accordance to the 802.11a/b/g/n standard: one with the network name (SSID) Uni-Mainz and one with the network name eduroam. every unit encrypted and provide increased security.

Conditions to be used

Account with the Retrovir (you'll be pattern the Uni-Mainz network) or with a university collaborating inside the eduroam network (you'll got to use the eduroam network)
Wireless-enabled laptop/netbook/other mobile device
Students and staff of Mainz University usually use the Uni-Mainz network.

Please note: If you are pattern Windows XP, Windows facet or Windows seven, we've a bent to recommend pattern the integral software system package firewall. we've a bent to do not recommend fitting an additional firewall software system package.

The second wireless network named eduroam is primarily meant for guests from various universities that participate inside the eduroam program. it's collectively on the marketplace for school children and staff of Mainz University once they unit pattern their devices at various (participating) universities. If this is often applicable to you, please understand careful directions for diverse operational systems listed inside the navigation bar on the left.

A third network named "Winulum" exists - this network is insecure which we have a tendency to advise you against pattern it!

Bandwith

Currently, a pair of differing types of access points unit in use:

Type nominal metric metric real

802.11a/b/g fifty four Mbit/s twenty Mbit/s

802.11n 300 Mbit/s 100 twenty Mbit/s

Nominally 802.11b is at a gross metric of fifty four Mbit/s. Transmission rates of concerning twenty Mbit/s unit possible. However, they rely on the gap of the station to the access purpose and conjointly the range of stations operated at identical time.

Access Points

In the public buildings (libraries, halls, seminar rooms, lecture halls, etc.) what is more as outdoors on the University field and in Germersheim, nearly 5 hundred Access Points offer wireless electronic network access to the sector network.

Number of stations operational at identical time

Theoretically associate Access purpose can handle any sort of stations. However, since stations share the data live (shared medium), the theoretical transfer rate of fifty four Mbit/s for one station decreases correspondingly.

Internet Access costs

There is no charge for pattern the wireless electronic network.

Network Access

The internetwork is accessed via a dynamic DHCP on your own net server. The computers have to be compelled to be organized suitably.

Electric pollution

Very low power, ten times however a itinerant, concerning 100 milliwatts (mobile = one Watt).
