A special-purpose mobile communication device using low-bandwidth cellular technology designed for IoT applications, such Narrowband LTE for IoT, is used to securely exchange voice messages in real-time or near real-time with another user. The voice messages are short duration voice messages, also referred to as voice clips, that are capable of being compressed using file compression algorithms instead of stream compression methods ordinarily used for real-time audio. A general-purpose mobile communication device activates the special-purpose devices and creates a private network for securely exchanging the voice messages between the devices. The general-purpose device also operates a mobile application that interfaces with a cloud-based mobile voice communication and location tracking system to manage the voice messages and track the location of the special-purpose device using Observed Time Difference of Arrival measurements.

Voice communication and location tracking system

A method and apparatus is disclosed herein for communicating between mobile devices. In one embodiment, the method comprises launching an application on a first mobile device, joining a wireless mesh network with the first mobile device being a node in the wireless mesh network in response to launching the application, discovering one or more other mobile devices that are active in the wireless mesh network using a discovery protocol, receiving profile information from each of the one or more other mobile devices, and displaying a visual directory of participants associated with the one or more other mobile devices active in the wireless mesh network.

Method and apparatus for communicating between mobile devices

A method and apparatus is disclosed herein for determining the location of a device with the assistance of fixed receivers. In one embodiment, the method comprises receiving a first request from the mobile device in the wireless network; wirelessly transmitting one or more positioning requests in response to the first request; receiving signal strength information from one or more receivers in the wireless network sent in response to the one or more positioning requests; determining a location of the mobile device based on received signal strength information by comparing the received signal strength information with signal strength information of reference locations; and sending location information to the mobile device, where the location information is indicative of the location of the mobile device.
