A data communications network comprises a plurality of geographically
spaced wireless transmitters each for transmitting a different network
address. At least one mobile user terminal has a wireless receiver for
receiving the network addresses transmitted by the transmitters, a
wireless transmitter for transmitting requests for delivery of data files
from remote locations identified by the network addresses, a wireless
receiver for receiving from the remote location the data files identified
by the network addresses, and output means for outputting the data files
received. Preferably, the network addresses each comprise a Uniform
Resource Locator and the data files each comprise a World Wide Web page.
