YDOC’s ML417 family of remote telemetry units are versatile and powerful. The ML417 utilises a global narrow band modem which supports all of the Cat M1 and NB 1 / NB IoT bands used across the world. |

The TBSL1 is a telemetry unit with some hidden features. One of these is the ability to swap out the modem board. Fitting the 4G modem board allows the unit to send data via the Cat M1 network. |

WiFi Telemetry |
|
|
WiFi is becoming ubiquitous - everywhere you turn you see another WiFi based product. While normally thought of as a short range, high data rate technology, WiFi is surprisingly adaptable and, given the right antenna choice can work over distances of 1 km WiFi was originally available on 2.4 GHz and then, as the need for more speed evolved, 4.8GHz was added. The higher frequency allows wider bandwidth and hence more data throughput, but comes with the consequence of reduced range. Which means that in field WiFi for telemetry is only useable on 2.4 GHz. A new lower frequency WiFi service has recently been developed. This takes the form of HaLow and operates on frequencies below 1GHz. See ourHaLow page for more information. |

Every ML417 or ML017 unit carries an expansion port in to which you can plug a WiFi expansion board. Just configure it with the details of the on site WiFi access point, and away you go. |

When the WiFi modem board is added, the TBSL1 can send its data through an on site WiFi connection. |

LoRa is an emerging radio technology which, through use of advanced modulation techniques offers long transmission range from low power devices - the term “LoRa” is a contraction of Long Range. |

The YDOC ML417 and ML017 units may also be fitted with an Iridium Edge modem, with data then transmitted over the Iridium satellite system. Sensori has been given an importer to allow it to collect data from the Iridium Servers via Email. |
