20170303233 | Mapping and Bridging Wireless Networks to Provide Better Service - Methods, systems, computer-readable media, and apparatuses for providing service to access nodes are presented. In some embodiments, a computing device may generate a geographical coverage map comprising a plurality of wireless access nodes respectively at a plurality of geographic locations and a wireless coverage range for each wireless access node. The computing device may receive from at least one wireless access node of the plurality of wireless access nodes an indication that the at least one wireless access node detected a first wireless access node of the plurality of wireless access nodes. The computing device may refine a first coverage range of the first wireless access node based on a respective geographic location of the at least one wireless access node. In some embodiments, a first wireless access node may receive and forward join emergency mesh (JEM) messages to establish a wireless network. | 2017-10-19 |
