The Myriota Network offers two communication service types. Both types downlink data from the Myriota Network using the UHF band, but differ on the frequency band used for uplink:
| Service Type | Module Variant | Uplink | Downlink |
|---|---|---|---|
| Service 1 | M1 | VHF | UHF |
| Service 2 | M2 | UHF | UHF |
For more information on the technical functionality of the module variants, please refer to the Myriota Module Datasheet. For detail on the antenna requirements for each service type, please refer to the Myriota Antenna Design Guide.
Why these frequencies?
The Myriota service types use the VHF and UHF frequency bands because they provide the best radio propagation conditions for direct-to-orbit IoT
- VHF and UHF frequencies have lower free-space path loss than higher frequencies. A more reliable link is created because signals stay strong for longer distances
- Low path loss allows low transmit power and long battery life, and the use of compact omnidirectional antennas
- These frequencies are less vulnerable to signal quality reduction due to poor weather conditions, such as attenuation induced by clouds, rain or snow
Which service type is right for me?
The choice as to which service type is right for your device will depend on the specific requirements of your use case, and our Designing for the Myriota Network - Service Types guide has been developed to help you to make that decision.
Please note, this guide will require you to login before you can access it. Simply use your Device Manager credentials when prompted.
Whilst you may have a service type preference depending on form, deployment environment, or inhouse capability, the requirements of each service are such that it is not necessary to make a choice between the two offerings in order to commence design and development.
Using the above guide in combination with the Myriota Antenna Design Guide you can rapidly develop and test your product under typical deployment conditions for each service type.
With the right hardware design, you can develop a band-neutral solution that provides compliance with minimal hardware changes, allowing you to push the selection of service type towards the end of your maker's journey.
