Скачать или смотреть goTenna Enables Communication without Cell Service

goTenna utilizes the Multi-Use Radio Service (MURS) frequencies to communicate short distances between two smart phones when no cell service is available. It pairs with a smart phone through an application using Bluetooth-LE enabling the user to send text messages and location details. goTenna acts like other antennas in that the range can be affected by both obstacles and altitude, giving the unit a maximum range of fifty miles under perfect conditions. Broadcasts from the goTenna will be received by all other goTenna devices in range, with encryption and, "self-destructing messages" for targeting a specific goTenna user or group.
