Car Hotspot / Public Hotspot

Areas with low reception and high speeds make reliable access to the Internet in the vehicle very difficult.

The Wi2U is a UMTS to WLAN router enabling a reliable and secure internet connection for end user devices such as smart phones, tablets or laptops in vehicles.



Scope of delivery 

The Wi2U comes with all accessories required for operation:

  • Wi2U WLAN to UMTS router
  • Internal UMTS antenna for the windscreen, with 3m connection cable and connection plug for Wi2U
  • Cable set for connection to vehicle power (12VDC or +24VDC) 
  • Connection cable for 12VDC cigarette lighter
  • Installation Kit for vehicle installation
  • Quick Start Guide


12 V Power Adapter

The 12 V power adapter for the Wi2U router connects the device to a regular wall outlet. It can be plugged directly into the wall socket, and connected to the Wi2U device via the connector used for the cigarette lighter. 

External GPS antenna

An external GPS antenna further improves the GPS connectivity of the Wi2U. Just like in the UTMS antenna, which is already included in the scope of delivery, it can be affixed to the windscreen and connected to the Wi2U router via cable. 

Technical Data

The Wi2U is a wireless LAN to UMTS router, which can accommodate up to eight mobile WLAN terminals. The router operates in the 2.4 GHz RF range. The router's core is the lesswire WLAN module 'WiBear-SF', which is suitable for robust in-car use of WLAN according to IEEE 802.11 b/g. 

Via the UMTS module integrated in the router, a fast and performant wireless internet connection with up to 7.2 Mbps download (HSPDA) and 5.7 Mbps upload speed (HSUPA) can be achieved - i.e. bandwidths inside your car, which are comparable with your home DSL network.
