Hello everyone!
We have a simple setup with one indoor gateway RAK7258 and two RAK811 Breakout Board end-nodes. The first end-node is near the gateway (a couple of meters) and sends regularly uplink messages to the RAK7258’s built-in app server, which in turn transmits data (downlink messages) to the second end-node. We are testing this in urban environment, but in a district with rather smal buildings, lot of free space everywhere. As such, we are expecting ranges of at least 1,5-2 km. Instead we’ve got 500-700 meters so far as the best result.
Here are some parameters of the devices:
RAK7258 - 868 Mhz, Tx power 14 Dbm, DR0 (SF12BW125), ADR off, 869.525 MHz SF9BW125 (RX2 downlink only)
RAK811 - 868 Mhz, DR0 (SF12BW125), ADR off.
We use default antennas that were delivered with the devices.
The question is, how to improve the range? Any suggestions, please!
Hi, Todor! Thank you for the reply! Could You please recommend some better antenna for RAK7258 (I didn’t find any from rakwireless’ store) or should we just change to outdoor gateway like RAK7249?
I have the same behavior with RAK811 based gateway. Max 600m. I installed a better antenna Fiber Glass Antenna - 5.8dBi and nothing changed, maybe 50m.
Where should investigate to troubleshoot the poor effenciency?
To connect the antenna using the N-type → RP-SMA you will need another RP-SMA male to N-type female.
Wouldn´t it be easier just to use something like a N Type Male to Female?
Obviously to connect to a RAK outdoor enclosure.
Or am i missing something?
