goTenna Pro will connect to any iOS (v 8.4 or higher) or Android (v 4.3 or higher) phone over Bluetooth Low-Energy (BT4.0+). The app on your phone is your end-user interface. Within the app you can type texts, create map objects like points, perimeters and shapes to share with others.
Does everyone have to have a goTenna Pro to communicate?
Yes. The device is the data conduit — it is entirely disconnected from the general network so you and each of your team members must have a goTenna to receive goTenna signals.
What range should I expect?
Range will be comparable with other high-quality VHF/UHF radio systems of similar frequency and power of the Pro. Range can vary widely depending on your environment, with open elevated environments being optimal, and obstructed, low-elevation environments resulting in less range.
How is the goTenna Pro charged, and what kind of battery does it have?
Standard micro-USB cable charging for a lithium-polymer battery.
What kind of warranty do you provide?
goTenna Pro comes with a 1-year limited warranty.
Is goTenna Pro waterproof?
Yes, goTenna Pro is rated at IP68, meaning it is fully submergible and dust-tight. Please note however that waterproofing on the Pro is dependent on an o-ring seal with the antenna and can only be guaranteed if using goTenna antennas. Although the Pro is compatible with off-the-shelf SMA antennas, it is possible that not all antennas will be able to create a waterproof seal with goTenna Pro. As such, we recommend the use of native goTenna antennas to ensure waterproofness, or the purchase of off-the-shelf antennas that include an o-ring base.
Is goTenna Pro intrinsically safe?
Yes, goTenna is certified for Type 2 intrinsic safety.
Is goTenna Pro MILSPEC certified?
Yes, please see spec sheet for specific subparts.
How many hops are supported in the mesh network?
At shipping, the Pro will support a 3-hop network. This will be expanded in the future via over-the-air software updates.
Will the goTenna Pro relay/mesh data even when not connected to a phone?
Will there be any indication that others are meshing my data / can people see our traffic via the hardware or app if I do not intend to communicate with them?
How long will a charge last on my goTenna Pro?
Like other high-power radio devices, battery life is highly dependent on usage. On standby, the goTenna Pro will last more than 60 hours on a single charge. Alternatively, a single charge will also support roughly 1,700 messages at a 5 W output power level, or 12,000 messages at a 500 mW output power level.
How long will it take to charge my goTenna Pro?
Charging can be fully completed in 4-6 hours depending on the power source.
How do frequencies work on the goTenna Pro?
The goTenna protocol operates on multiple frequencies simultaneously. These groups of eligible operating frequencies and settings are called “frequency sets.” These sets are what are selected to tune your Pro for operation.
What is a frequency set?
goTenna Pro operates with a minimum of 2 and a maximum of 16 frequencies at a time which — together with some other RF parameters — are grouped together into a “frequency set.” This set of frequencies represents the eligible frequencies that your organization has licenses to operate on. Upon being given its set of eligible frequencies via the frequency set, the goTenna Pro’s protocol will automatically run on those frequencies avoiding interference when necessary.
What are the components of a frequency set?
Minimum 1 control channel<br/ > 1-15 data channels<br/ > Deviation/bandwidth<br/ > Maximum output power<br/ > FCC call sign (where applicable)<br/ > Name, description, and instructions (optional)
Can I use multiple frequency sets?
You can toggle between multiple frequency settings. However, your goTenna Pro will only operate on one frequency set at a time. Users must be on the same frequency set to communicate or mesh.
How do I tune my goTenna Pro?
Your device can be tuned in two ways. The primary tuning method is remote via the goTenna Pro Management Portal. Within the Portal — which is included with every goTenna Pro purchase — authorized administrators and service personnel will set the appropriate operating frequencies for your organization in line with their licenses via the creation of frequency sets. End-users then need only to log into their organizations via the goTenna Pro App. All eligible frequency sets will be downloaded automatically to their devices and will be available for use offline. If multiple frequency sets are available, the end user can toggle between them. Alternately, authorized service users have the ability to make, edit and share frequency sets in the field without any interdependence with the cloud Portal via the goTenna Pro app.
What power levels can I use?
500 MW, 1 W, 2 W and 5 W modes.
What bandwidths are supported?
25 kHz, 12.5 kHz, 25 kHz.
What is the resolution of frequencies?
The goTenna Pro can tune to 4 decimal points. For example, 142.8345 MHz.
Will the Pro avoid interfering with other devices?
The goTenna protocol will cognitively sense all of its eligible operating frequencies and will actively avoid using any frequencies that are being used by other comms systems at the same time. If all eligible operating frequencies are occupied, the protocol will execute listen-before-talk (LBT) and await an open opportunity to transmit. We do however recommend using a dedicated frequency for your goTenna Pro control channel.
Will goTenna Pro work with any off-the-shelf antenna?
Yes, the device offers a standardized 50-ohm SMA connector compatible with most off-the-shelf antennas.
What antenna is included with the Pro?
An 8-inch antenna is included with the purchase of every Pro device. You have the ability to select which particular tune of the antenna you would like at shipping, or you may purchase spares/alternates as well.
Do I need a license to operate goTenna Pro?
In the United States, goTenna Pro is licensed under Part 90 of FCC regulations, which does require any organization operating radio equipment in this space to procure a license before operation. International regulations may vary, but it is the responsibility of the end customer to ensure compliance with all local frequency regulations.
Does goTenna get a license for me?
No, it is the responsibility of the end customer to ensure that a license is properly acquired before operating goTenna Pro.
Is goTenna Pro interoperable with goTenna or goTenna Mesh?
Due to FCC regulations Part 90, devices cannot operate on consumer frequencies or vice-versa.
What part of FCC rules is the goTenna Pro licensed under?
goTenna Pro Deployment Kit
How does app deployment work?
The goTenna Pro Deployment Kit will create a local wifi hotspot that any user can connect to with their phone. Upon connection, the user can open any browser on the their phone and attempt to navigate to any page, or just hit refresh. Upon doing so, the Kit will redirect the user’s browser to a locally-hosted page which will allow the user to install the goTenna app, or any other partner app, on their phone with one click, without any internet connectivity.
What platforms are supported for app deployment?
iOS and Android.
Can other apps besides goTenna be hosted and deployed via the Kit?
es, any application for Android or iOS can be hosted on the Kit. Only the goTenna app is hosted by default on the Kit, but an admin can add any new APK (Android) or Enterprise IPA (iOS) files to the organizations’ Kits via the Portal.
Can I take the Kit as a carry-on on a commercial airline?
The Kit is designed to conform to the majority of commercial airline carry-on rules. Rules do change from carrier to carrier however, so it is possible that certain airlines may charge fees or have other restrictions.
How are firmware updates executed?
All firmware updates are completed automatically while Pro units are connected to the Kit, even when the Pro units are turned off. The firmware is pushed from the Portal, and the Kit will automatically update all units with the appropriate firmware.
Can the Kit handle an unregulated power source such as a generator?
Yes, the Kit is designed to withstand the stresses of variable power sources.
What kind of auxiliary power can the Kit accept?
8-14 V inputs via the “cigarette lighter” auxiliary power port.
How does the Kit remain synced with the Portal?
When not in deployment mode, the Kit can connect to wifi and will be logged into a Portal account.
Can the Kit be connected to the internet and simultaneously deploy apps as well?
No, the kit can either connect to wifi or it can generate its own wifi hotspot. It cannot do both at the same time.
What kind of battery is in the Kit?
The Kit includes a battery that was selected due to inherent chemical safety that makes it very difficult to destroy or combust.
Will the Kit support the consumer models?
The Kit will charge anything via USB power, however it will not distribute the consumer application or execute FW updates on the consumer models.
Can map files be deployed via the Kit?
Yes, however the specific maps stored on the Kit must be preset and loaded by the admin via the Management Portal.
You can make the following types of map pins: general marker, emergency marker, danger marker.
How does perimeter and route/line marking work?
You can create a perimeter by placing up to 8 anchor points on the map. When you are done, you hit the “complete” button and the first/last points will be connected and the area bound by your anchor points will be shaded. You can then name and share this perimeter. The route/line function works in precisely the same manner; however, the first/last points are not connected, and there is no shading.
How does the shapes tool work?
You can select to make a square, circle or cone shape. All shapes begin via a starting anchor point, and then you can pinch the screen to change the size and orientation of the shape. Upon completion you may name the shape and share it with others.
How many people can you have in a group?
For users of the Pro app, you can create private groups of up to 10 people in the field. To make larger private groups of unlimited size, they must be initially created while still connected to the internet/portal or a goTenna Pro Deployment Kit. After initial creation of a larger group online, it will functional the same as any smaller group offline.
Will the Pro app work with consumer hardware such as first-generation goTenna and goTenna Mesh?
Will the consumer app work with the Pro hardware?
How does the app sync with the Portal?
Every end-user in an organization must be provisioned via the Portal or a service user in off-grid scenarios. Normally a login and password is sent from the portal to a user’s email, and the user will use these credentials to log in via the app to establish the sync, tuning, and appropriate field permissions.
How does setup work for off-grid deployments?
When offline you may set up your app using a randomized ID which does not require any network connectivity. This is like your “phone number,” which you need to share with partners to communicate. You can also broadcast your identity on an open channel to automatically share your ID globally with others.
How do I manage/tune my users’ Pro devices?
Within the portal, authorized admins can create and edit “frequency sets” for their organizations. These frequency sets are then pushed to end users when they log in via their app. Please see the frequency set FAQ item for more details on the function and process of managing frequency sets.
How do I provision new users for my organization?
You can create new users from the portal and, via email, they will get login credentials which will allow them to log in via the goTenna Pro app with the appropriate permissions and settings.
What kinds of user profiles exist?
There are 2 primary user types for Basic accounts: “end user” and “service user.” The primary difference between user types is that service users have the ability to create, edit and distribute frequency sets in the field independent of the management portal. Due to FCC regulations, service users are the only personnel that can have tuning access.
What is firmware?
Firmware is the software running on the goTenna Pro hardware. It is the heart of the product and as such it is not often updated, but when it is it is usually a critical update with significant enhancements.
What does it mean to manage firmware?
For some organizations (usually governmental), policies require that the organization remain on a locked version of the firmware until a new version is properly approved via internal testing. For customers with these requirements, the portal will enable you to lock or rollback to an approved version of firmware.
Do I have to manage firmware?
No, in fact we don’t recommend it. By default every account will be signed up for automatic firmware updates, ensuring your hardware will always be on the latest firmware version. We offer this feature for flexibility with certain clients' internal requirements (usually governmental).
What type of encryption does goTenna use?
Private 1-to-1 and group messages sent over goTenna are end-to-end encrypted with 384-bit elliptic curve public-private key ciphering. The only exceptions are messages sent using the “shout” and “emergency” features which are by definition public conversations with others within range of you.
How secure is goTenna?
Very. Beyond the end-to-end encryption, because there is no central server there is no proverbial "back door."
Can other people with goTenna devices gain access to messages I send?
No, everything is encrypted and our firmware doesn't allow downloading one goTenna account's messages to another smartphone anyway.
What information does my goTenna store?
Just the goTenna ID you’ve set to be your contact (i.e. either your phone number or a randomized string), and any messages your phone hasn’t pulled yet. If you opt in to telemetry, we’ll gather some basic statistics to help make goTenna better like battery life, device temperature, and so forth — absolutely zero actual messages or contact list information though!
What information does my goTenna device share with goTenna the company?
None, though you can opt-in to share completely anonymized telemetry when you have a data connection, so that we can improve our service. Again, this is limited to basic data regarding battery life, device temperature, and so forth. No messages or contact list info are included.
Why should I believe goTenna cares about my privacy?
We feel you. It's hard to sort out who pays lip service to privacy and who really means it these days. The sad reality is both the government and tech companies have disrespected our privacy, time and time again. Well, we have this to say about goTenna: We set out to build a consumer-ready, completely decentralized, end-to-end encrypted communication technology, without a "back door" for anyone, because it didn't exist yet, and we thought it should. We'll leave it at that.
