When travelling to work, using a cross-country train, there are often areas to which wireless broadband has, so far, failed to stretch (a fact which Vodafone omits to mention in their sales literature).
Today’s invention is wireless hub located in a station which knows about my journey and the blackspots I can expect to encounter (It might even correlate the tickets sold with the anticipated bandwidth requirements of the travellers’ journeys).
It then allocates those with large expected outages with massive bandwidth whilst waiting, so that their browsers can download all their tabbed sites ultra-fast before setting off. Those with small blackspots will get correspondingly lower bitrates whilst waiting.
