LTE
Stands for Long Term Evolution. This term stands for an internationally common mobile radio procedure for
fast data transmission via the mobile communications network.
Instead of LTE, the synonym "4G" is often used as well. This stands for "4th generation mobile communications
networks".
LTE is expressly used for data transmission, not telephony. In the meantime, however, procedures have been
introduced that can route voice telephony via LTE data packets (VoLTE).
Outdoor unit
The part of the Oyster® Connect system which is installed on the vehicle roof.
Open (WLAN) network
A network which is available for everybody and does not require a password. However, using it poses a safety
risk!
PIN code / SIM PIN / PUK code
PIN stands for "Personal Identification Number". Similar to the secret code on your bank card, it protects this
SIM card from being used by unauthorised persons.
If the PIN is entered incorrectly too often, the card can no longer be unblocked, even with the correct PIN. In that
case, the block can be removed by using the PUK code.
Both codes are usually included with the SIM card on delivery.
Private (WLAN) network
Password-protected network which is therefore only accessible to a limited number of users.
Referring to the Oyster® Connect, we specifically mean the vehicle-based WLAN, which is provided by the indoor
unit for your own end devices.
SIM card
This is the small chip card you receive from your mobile communications operator. It is inserted into the appro-
priate card reader of the outdoor unit. The SIM card size for the Oyster® Connect is a "Mini-SIM".

WLAN
Stands for "Wireless Local Area Network". Internationally often called "WIFI". WLAN is used to establish a wire-
less network between several devices via radio connection.
2.4 GHz WLAN networks usually have the greater range. However, they are often overloaded by a large number
of competing networks and users and can be slow.
5 GHz WLAN networks usually have a shorter range but in practice, they offer significantly faster data speeds.
WLAN hotspot or WLAN access point
A publicly offered WLAN. Partly for a fee, or only usable for certain users (for example Telekom customers on
Telekom hotspots). Some WLAN access points are free of charge but require an access authorisation.
Usually the devices registered there can only access the Internet but they cannot communicate with each
other.
WLAN channel
Similar to TV broadcasting, several channels are also available for WLAN devices. This allows trouble-free and
parallel operation of various WLAN networks provided that their channels have been sensibly selected.
The WLAN channel to be used and other parameters are selected on the transmitter's side. The end devices rec-
ognise this and automatically adjust to it.
WPS
WPS stands for "WiFi Protected Setup". This function is supported by some end devices. It is used to connect
two WPS-enabled devices to each other via WLAN without entering a password.
For this, first set the router to a time-limited login mode (press the WPS button), and then start the login process
on the end device's WLAN settings. When both devices are within radio range of each other, they will now find
each other and automatically establish the connection.
Afterwards, the router's login readiness is automatically terminated.
