Everyone nowadays uses smartphone, and people go to very extreme locations. For example, you can take my home which is right at the international border and I can guarantee that you won’t get reliable service from any carrier except BSNL (Bharat Sanchar Nigam Limited) and Vodafone India, due to certain Govt. restrictions, and there are such many places especially the mountains where you will always face connectivity issues. Sometimes, you may be in an emergency but your carrier betrayed you. This thing can go wrong if you can’t connect to someone when you need help. So, here’s a device that can help you turn your smartphone into a CB (Citizens Band) Radio, and help you shout to all the CB radio nearby and you can ask for help in an emergency.
This gadget is called as GoTenna and is essentially a small, low-power (2 watts) radio transceiver. It’s powered by a lithium-ion battery, and it connects to your smartphone or tablet via Bluetooth. The company behind GoTenna claims that it has a maximum range of up to 50 miles, it probably transmits on a very low frequency and probably has very low max bandwidth. GoTenna creates an ad-hoc, encrypted network between any other GoTennas in range. It’s like a smartphone with a feature like CB radio.
You just need to download the GoTenna app on your iOS or Android device and when you’re in some emergency, you need to connect your phone to GoTenna and just you need a shout out via the app. Depending on your elevation and environment, the signal can travel upwards of 50 miles. You can add other users and connect with them in the case of emergency, but a “shout” feature allows messaging any GoTenna user within range. It doesn’t use cell towers or WiFi at all. Therefore, you don’t need any to stay connected to any kind of wireless network, just you need to connect your phone to GoTenna and give a shout out. This is how it will work.
