As may be appreciated, the present communication and emergency alert system may be used by many different groups of administrators to communicate with many different communities of people. Moreover, certain individuals may be members of more than one community at the same time, and the communities themselves may change over time based both on the user's preferences and on their physical locations. The location of an individual may be determined based on location data provided by their mobile device and refined using known landmarks, such as beacons and/or access points, located in the location. ## Claims ### Claim 1 A computer-implemented method, comprising: obtaining an indication of an alert condition in a facility;

and automatically adding the second mobile device to a community for the facility, wherein the community comprises the plurality of mobile devices. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, further comprising: identifying a mobile device in the plurality of mobile devices for which a location has not been determined; determining a proxy location for the mobile device; and using the proxy location for the mobile device as the location of the mobile device. ### Claim 6 (depends on 5) The computer-implemented method of claim 5, wherein: the mobile device is associated with a user; an access card is associated with the user; and the proxy location comprises an access device at which the access card associated with the user was used. ### Claim 7 (depends on 5) The computer-implemented method of claim 5, wherein the proxy location comprises a location of a wireless access point to which the mobile device is connected. ### Claim 8 A computing device, comprising: a processor; and a memory in communication with the processor and storing instructions that, when read by the processor, cause the computing device to: obtain an indication of an alert condition in a facility; determine that the alert condition comprises an emergency condition in a first portion of the facility; determine a location for a plurality of mobile devices, each mobile device being located in the facility; determine, for each mobile device in the plurality of mobile devices, an exit location for the mobile device;
