KNOT LR8/LR9 kit: Versatility on a Whole New Level

The KNOT: So Practical It's Almost Literal!

IoT networks expand over time, and more often than you think, one's faced with a colorful yet complicated juxtaposition of devices with different interfaces and various communication protocols. Having a hardware to integrate all these devices into a single system sounds too good to be true...

 

Or does it?

 

Worry no more, because you can now almost literally tie those devices together in a KNOT; no pun intended!

“The Whole Swiss Army!”

The KNOT LR8/LR9 kit is an “out-of-the-box gateway solution for the LoRa® technology” that can be utilized both as an Ethernet backup connection or as a management device.

 

It is the first of its kind to use a CAT-M interface for LoRa®, as well as the Narrow Band technology, and, due to the low cost, low bandwidth connection required, it is supported by numerous mobile operators worldwide.

 

Moreover, given its diverse port and peripheral arrangement, MikroTik’s KNOT brings you the maximum flexibility and practicality. This device has a pair of 100 Mbps Ethernet ports with PoE-in and PoE-out, 2.4 GHz wireless, Bluetooth, LoRa®, a Micro-USB port, and a NanoSIM slot!

The KNOT is a Team Player

On its own, the KNOT is highly useful. However, once paired with other IoT devices will it reveal its true potential. With the support of 8 different channels, Listen Before Talk (LBT) feature, spectral scan, and powerful filter settings for packet forwarding purposes, the KNOT can help you out in a variety of tricky scenarios.

 

One such solution is asset tracking and telemetry through Bluetooth, and, for that, you have the brand new MikroTik TG-BT5-IN and TG-BT5-OUT Bluetooth tags.

These slim indoor/outdoor tags can be used with the KNOT and other IoT asset tracking and telemetry projects. They use Bluetooth technology to broadcast data over short distances with the aim of conveying different types of information, such as proximity, movement, tilting, acceleration, fall, and many others.

 

Upon activation, these tags will broadcast iBeacon, Eddystone or MikroTik telemetry advertising packets to the KNOT as the gateway, which in turn will transmit the data to your servers.

Within a network, a few KNOT gateways and a handful of these Bluetooth tags can cover wide indoor and/or outdoor areas and provide various types of tracking and monitoring data for different items, assets, shipments, etc. within numerous scenarios, including hospitals, hotels, construction sites, warehouses, agricultural environments, commercial buildings, residential spaces and so on.

And just in case you're worried about the KNOT's coverage, you have the HGO-LTE-antenna W, and IoT antenna that supports both LTE and the LoRa® frequencies.

 

Suitable for KNOT LR series, this antenna covers a whopping 699 MHz to 3,8 GHz range: A single antenna handling all TE, CAT-M/NB and LoRa® connectivity!

The KNOT mounts everywhere with a DIN rail mount, and the tags, small and light (7 & 27 grams, respectively) attach to other items with straps, tapes, or a screw.

Watch Them in Action!

Here’s how the KNOT and its inexpensive Bluetooth tags can be operated in real-life.

 

Medical centers, especially referral hospitals, are usually jam-packed with patients, visitors, and professional personnel. What’s more, movement of hospital items and assets, expensive or otherwise essential, is happening round the clock. It would be quite a feat to keep an eye on the entire hospital inventory using a pen and pad.

Enter the KNOT. You simply stick a Bluetooth tag on all items of value, such as hospital beds, medications, equipment, etc., add a KNOT hardware in every storage room or other locations where items enter or exit, and easily keep track of all movements online.

 

And that’s not all! Using different IoT trackers and measuring gadgets, you’ll be able to monitor temperature and moisture levels, the condition of sensitive equipment, patients’ status, health and hygiene conditions, and so much more! And the hospital was just an example. The applications of the KNOT in different industries are endless!
