Modulator -- A Digital Walkie-Talkie Moto Mod For Moto Z Devices

[kevinobriendotca]

Hey Moto Z fans, we were originally working on a module for Project Ara and have shifted focus to developing a digital walkie-talkie Moto Mod for Moto Z devices and we need your support.

If you think secure, point-to-point communications is something you could use, please support our Indiegogo campaign:

Our Modulator digital walkie-talkie Moto Mod operates in the 902-928 Mhz ISM frequency band so you don't pay any fees. Our software uses a combination of strong encryption (AES-256, PBKDF2 / HMAC SHA256) and frequency hopping to greatly reduce the chance of your private messages being intercepted. The Modulator software is FCC part 15.247 compliant allowing us to use the maximum transmit power for the 900 Mhz ISM band, 1 watt.

We're also going to be selling the Raspberry Pi compatible prototype radio transceivers so people can use a Raspberry Pi as a base station connected to their home network or as a mobile battery powered base station. There are plans to enable the native Zigbee hardware support to use the Modulator Moto Mod as a technicians field tool as well.

Thanks for your support!

What is the maximum range?

What is the maximum range?

The range is really going to depend on the surrounding environment. Our range testing in the city gives us between 1 and 2 km with one of the radios in a concrete and steel building and the other radio in an SUV. With both radios outdoors the range increases to between 4 and 5 km depending on obstructions. If you are transmitting from an elevated position you can get considerably better range, beyond 10km.

Here are some links to videos showing range tests of similar radios with similar output power transmitting in the 900 Mhz ISM band:
