Glamos Walker Helium Testing Device – EU868 Frequency

Glamos Walker – all you need to take one step forward with LoRaWAN

Glamos Walker is a portable device that allows testing of the LoRaWAN network (LoRaWAN field test device). This device allows you to send, receive and instantly view radio packets & messages.

The user can change all parameters relevant to the network quality through the on-screen menu.

Walker also has a GPS module that allows instant positioning, and thus mapping the network itself.

It helps to decide on the best placement of gateways and antennas relative to each other.

All your data in hand

With the integration of the Walker device on the Walk App server (HTTP POST integration), the user is able to view all the data about the sent message on the screen of the device, but also within the Walk App. This includes sending time, counter, frequency, spreading factor (SF), bandwidth, coding rate, GPS coordinates, name of all base stations that received the message along with the corresponding RSSI and SNR values. The device will calculate packet error rate for you.

Real-time monitoring

If the Walker has access to the Wi-Fi network (or a smartphone hotspot) during operation, it will display the names of all gateways that received the message, together with the corresponding RSSI and SNR values. This feature is an ideal way for the user to see network quality in real time, not only based on signal quality, but also based on the overlap of multiple gateways.

Example: you send a message on the desired SF, and on the screen you will get information about exactly which base stations received the message and with what signal strength.

Use cases

• Optimisation of location for devices – know where to set up a device in advance
• Optimisation of location for gateways – learn about your gateway and location's performance
• Network coverage testing – map your network; create a map to know what area your hotspot (or another) is covering with signal
• Signal quality (RSSI and SNR)
• Indoor testing – find out how buildings affect your network
• Testing location for Helium hotspot placement (see how many hotspots you can see from a location, or whether you see any, before setting up your hotspot) – analytics for Proof of Coverage (PoC) (in the app you can see if you have a valid PoC from a location)
• Signal quality testing (RSSI and SNR) – see how good the signal is, important for PoC and mining
• Testing with different antennas to find the best fit – 3 antennas included (every device and hotspot has a different antenna, so you can test them to get the best signal for communication or to find the golden point for mining)
• Visualisation of all data in the app (all data is stored in Walk App so you can see it on a map and analyse it later)
• Get a list of hotspots in range on the device screen or in the app
• Learning about LoRaWAN (using the device you will learn how LoRaWAN and RF work – the best way to improve knowledge from theory is practical testing)

Configurable parameters

The user can change all parameters directly on the device – no need for reprogramming on a computer. That includes:

• Spreading factor
• Spreading factor on RX2 slot (SF9 or SF12)
• Multi-channel or single-channel (if you suspect some channel is not working properly)
• Sending geolocation in the message or not
• Setting up Wi-Fi parameters
• Sending confirmed/unconfirmed messages

Different modes for testing

To speed up testing there are many different modes of work:

• Send on one SF (configure it easily on screen)
• Send on even SFs (analyse network quality on SF8, SF10 and SF12)
• Send on odd SFs (analyse network quality on SF7, SF9 and SF11)
• Send on all SFs (analyse network quality on all SFs at once)
• Send a few messages in a row to get an average RSSI
• Send with a period on the same SF (can also be used as a GPS tracker)
