Walkie-talkies are a common means of coordinating activities at events but must be handed out, transferred as shifts and personnel in roles change, and collected. Further, walkie-talkies have a set range and the bigger the range the more expensive the walkie-talkie. Accordingly, it would be beneficial to provide individuals, enterprises, organizers, etc. with the ability to establish communications to individuals or group of individuals rapidly, with low complexity and management overhead, exploiting walkie-talkie style communications upon mobile devices connected to wireless networks over varying geographical areas without requiring distribution of walkie-talkies etc. as the mobile device is the user's own smartphone or cellphone. Further, it would be beneficial for such communications to be managed through a software application such that the user's virtual walkie-talkie automatically assigns channels etc. based upon the user's role, the event, their location etc. |
