Setting up and maintaining wireless communication connections with end user's terminals () on board a predictably moving vehicle () is shown with mechanisms for correcting for Doppler effects. A central device () within the vehicle () acts as a hub of a wireless network. There are a number of fixed transceivers (). A connection arrangement () connects the fixed transceivers () to an external packet-switched data network. The central device () within the vehicle () is a mobile router () equipped with routing capability (). The connection arrangement () includes a connection () between a number of fixed transceivers () and a fixed central device () The fixed central device () has routing capability (), and together with the mobile router () implement routing of packets between the packet-switched network and an end user's terminal ().

Method, system and arrangements for setting up and maintaining a WLAN connection within predictably moving vehicles

A system for propagating information among wireless communication devices in an efficient manner. More specifically, the invention involves regulating the behavior of a wireless communication device (WCD) between a primarily passive mode where client or slave availability is maximized and a primarily active mode where information propagation or master behavior is maximized. The regulation of the WCD is controlled based on the environment surrounding the WCD, including the devices in effective transmission range of the device, and the current condition of the WCD.
