The techniques include determining, using at least one processor, when a first item of information of the first type and a second item of information of the second type are to be updated, wherein the second item of information is to be updated more frequently than the first item of information; and causing the device to update the first and second items of information in accordance with the determination at least in part by wirelessly communicating with at least one other device. ## Claims ### Claim 1 A server connected to a wireless network, comprising: circuitry configured to: divide an area into a plurality of defined geographical areas;
