BearTooth is now accepting PreOrders.....

BearTooth is the Spread Spectrum 900Mhz cousin, to the GoTenna which is a MURS (150 Mhz) Wireless Devise that connects any BlueTooth Communications Devices together, over non-Cellular Frequencies....

Beartooth - Communicate Off the Grid

goTenna | Text & GPS on your phone, even without service.

The BearTooth will have similar Ranges, to the SECURE Phones that many of the Monkeys, have invested in, for SECURE Comms. It has the Advantage, of using the connected Device, (iPhone, iPad, Notebook, Laptop, etc) to Encrypt the data to be passed, over and above the Spread Spectrum Digital Voice Modulation, that the SECURE PHONES use.... Also if you are a Holder of a Ham Radio License, you can employ an External Amplifier, (10 Watts Max) and As much external Antenna Gain as you can Build, as this is a legal Ham Frequency Band...



Both devices are NOW advertising their products at $99.00US ea, Each has advantages and disadvantages, but effectively do the same things....

 

Actually, 900 Mhz will propigate down that canyon very nicely, by bouncing off the Vertical Walls... Basically, it is just like a big Waveguide, at that frequency....

 

If you look in CFR47Part 97.311, they talk about Spread Spectrum Specific Regulations... There is NO Type Approval required for Ham Equipment, except for HF Amplifiers... You can modify ANY Radio Apparatus as you like, as long as the Emissions, stay within the Part 97 Regulations. The Power Limit, for Spread Spectrum, is 10 Watts PEP, and it is an ALLOWED Emission, in the 902-928Mhz Ham Band... The 10Watt Limit was imposed a few years back, due to some folks using 1.5Kw and doing MoonBounce with it, in this band...
Lots of possibilities with this piece of Gear, an Amp, and High Gain Antenna... which is why I bring it up... I did a PreOrder yeaterday, and the price for 2 Units was $149.00US....

 

@azrancher
It is a Bluetooth to 900Mhz Spread Spectrum Bidirectional Repeater.... (1 Watt ) It connects any Bluetooth Device with an IP Stack, to the 900Mhz Spread Spectrum Transceiver, that then can connect, with any other similar 900Mhz Spread Spectrum Transceiver, and then back to it's associated Bluetooth Device, with an IP Stack.... By doing so, all these, BlueTooth IP Devices can pass traffic, back and forth.... (Text, Pictures, Voice, Data, Video, ETC) and all the Traffic could be End to End Encrypted, depending on the BlueTooth Device's Apps that it has loaded, that is generating, or receiving the Data Stream...
Ok, Like of you had an iPhone, on each end, and you were in a non-Cellular Coverage Area, and outside WiFi Range of the Other Unit, but still within the Range of the 900Mhz Spread Spectrum Radios, then you build an AdHoc Network, or if you have more than Two Units, you build a MESH Network, and this allows, you to pass traffic between Units, depending on the Network that you build.
SHTF Senerio.... CellSites are DOWN, You and your Group, are at your BugOut Location, which is Bigger than can be covered by WiFi... and you build a MESH Network, with ALL the Groups Units, paired with their individual iPhones. A Scout sees incoming Personnel, that may or may NOT be friendly. They take video of the approach, and Pass it to the HQ, via the MESH Network.(Maybe thru, as many as 3 or 4 Units strung out, in a line, to extend the Range of the Network) The HQ folks decide these are Good guys and they pass back an iMessage, or even a FaceTime Video, or Audio, Call, to the Scout to let them pass... Or say they are BAD Guys, and the HQ, then foments the Defense Plan, and sends that out to ALL Group Members, and they ambush the Intruders, and blow their A$$es to Kingdom Come...... Keeping in mind, that all this is SECURE Comms. By being Spread Spectrum Digital Modulation, that can NOT be DF'ed, or Monitored by Normal Methods, and even IF, it is monitored, by a Real Expensive Setup, and since it is "End to End Encrypted" by the iPhones on each end, it is useless to the Intruder, as THEY can't break the Encryption, even if they are the NSA/FBI/CommiePinko/ __________ (Name you Bad Guy Group) because even Apple can't break the encryption as it stands, NOW....

The GoTenna is a similar Device, that runs on MURS Frequencies, (2 Watts VHF 150 Mhz) but CAN be DF'ed, and as of NOW it can only pass Text Traffic... (They are working on other forms of Data, but that is still not REAL, at this point...)

 

I am not aware that the iDen Phones had an IP Stack, or BlueTooth, in them, and they would NOT communicate on 900Mhz as they would be using a DIFFERENT Spread Spectrum Modulation System... They share the same Frequency Band, but use twice the Bandwidth. (Only have 5 Channels, instead of 10 that the. SECURE Phones, have)

 

If one has an iPhone then the Voice Comms Apps like FaceTime are already End. To End Encrypted... There are a number of iPhone Voice Apps that do End to End Encryption... I haven't played with the devices yet, but if they use a programmable Spreading Code, similar to the SECURE Phones do, as well as a choice of Frequencies, then that will protect against just normal evesdropping by another Unit that is NOT setup the same as the two communicating units... In a MESH Network, only those units with the exact same Spreading Code, would be part of the Network, and only the Originating Unit, and End Unit, would be able to decrypt the End to End Encrypted Data Stream... Even if it was passed thru multiple MESH Network Units... While in transit...

 

woops! Sorry about that.

 

Yes, they Pair, just like any other Bluetooth Device, that is looking for a IP Stack to communicate with, on the Paired Device...
