@gerard_alticom invited us to the well-known Alticom radio tower and data center in the Waarderpolder today, to discuss options to get a gateway installed at 95 meters.
As shown earlier by others, near line-of-sight situations with high altitude gateways/nodes can yield very nice ranges:
That is, an ESP8266/RFM95W node with a dipole antenna, sending at SF7, SF9 and SF12, got its packets received at:
- Dronten, 0000024B080E00E0, 73 km, SF12
- Utrecht, AA555A00080605B7, 48 km, SF7/9/12
- Almere, 1DEE1EAE2E9F468B, 34 km, SF12
- Almere, AA555A0008060249, 34 km, SF7/9/12
- Oegstgeest, 1DEE04187DBF1BC6, 28 km, SF12
- Noordwijk, 008000000000A46D, 23 km, SF7/9/12
- Voorhout, FFFEB827EB6A415C, 23 km, SF12
- Amsterdam Buitenveldert, 008000000000B098, 15 km, SF12
- Zwanenburg, B827EBFFFEDFCD10, 5 km, SF9/12
- Haarlem, B827EBFFFF5FE05C, 3km, SF12 (single channel gateway, 1st floor)
And maybe some other gateways did not yet migrate to the new staging environment, which we used to get these results.
Also, the municipality of Haarlem installed the first two Libelium Plug & Sense nodes this Monday. Try to find them
