Glamos Walker Lorawan field tester

GLAMOS Walker – all you need to make one step forward with LoRaWAN and Helium

GLAMOS Walker – Most advanced LoRaWAN and Helium testing tool. Helps with setting up hotspots, testing locations/antennas and doing coverage mapping.

Glamos Walker is a portable device that allows testing of the LoRaWAN network (LoRaWAN field test 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 devices relative to each other.

All data on your 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. Device will calculate Packet error rate for you.

Real time monitoring

If the Walker has access to the WiFi network (or 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

• Optimization of location for devices – know where to set up device in advance
• Optimization of location for gateways – know how good performance does your gateway and its location have
• Network coverage testing – map your network (you can create map to know what area your hotspot, or some other, is covering with signal)
• Signal quality (RSSI and SNR)
• Indoor testing – find out how buildings affect your network
• testing location for HELIUM hotspot placement (you are able to see how many hotspots you can see from some locations, or do you see any, before setting up your hotspot)- analytics for Proof of Coverage (PoC) (in app you can see if you have valid PoC from location)
• Signal quality testing (RSSI and SNR) – you can see how good signal is because that is important for PoC and mining
• Testing with different antennas to find best fit – 3 antennas included (every device and hotspot has different antenna, so you can test them to get best signal for communication or to find golden point for mining)
• Visualization of all data in app (all data are stored in Walk App so you can see them on map and analyze it later https://glamos.eu/walkapp)
• get list of hotspots in range on screen of device or in app
• LEARNING about LoRaWAN (using GLAMOS Walker you will learn how LoRaWAN and RF works. Best way to improve knowledge from theory is to make practical testings)

Configurable parameters

User can change all parameteres directly on device, no need for reprogramming on 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 message or not
• Setting up WiFi parameters
• Send 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 (analyze quality of network on SF8, SF10 and SF12)
• Send on odd SFs (analyze quality of network on SF7, SF9 and SF11)
• Send on all SFs (analyze quality of network on all SFs at once)
• Send few messages in a row to get average RSSI
• Send with period on same SF (possible to use as GPS tracker also)
