The first Locha Mesh's Turpial dev-kits in the wild | 2021-01-03

20210103_144119 2

On January 3rd 2021, Luis and Jean from the Locha Mesh team deployed
the first Turpial dev-kit nodes to carry out range tests with static
and mobile nodes from different locations, with nodes in line of
sight and NLoS. The experiment was designed with default values, 200
kbps speed, and omnidirectional antennas.

Initially, a static node was deployed in the coordinates 40.398935,
-4.503101, its purpose was to send UDP packets periodically to
measure the quality of the signal in the chosen test points by using
an SDR, while additionally verifying the packet reception with a
mobile Turpial node that was with the team the whole time.

Once the on site Turpial node was up and running, our team left for a
drive to the first checkpoint, measuring the quality of the
connection during the ride as the reception of the UDP packets
broadcasted by the base node.

The team witnessed and recorded the outstanding quality of the
reception in several points at different altitudes, inside and around
the town.

First checkpoint (A) was located at 40.401402, -4.481335, 1.8 km from
base node in LoS, so the values obtained were the ones we expected,
good RSSI and 100% of sent packets were captured.

Second checkpoint (B) at 40.430277, -4.477927, 4.13 km from base node
NLoS, the team recorded excellent results.

The team then headed to the third checkpoint (C) located at
40.458331, -4.480083 where during the ride several shadow and
coverage zones were identified. Nevertheless as the team arrived at
the checkpoint NLoS, they noticed a stable signal being received with
a RSSI of -103 dBm and 70% of the UDP packets casted by the base node
were captured.

Summarizing, the largest distance reached in this test was 7.16 km
NLoS in the third checkpoint.

We want to thank the community for supporting us, this has been an
exciting experience since we started. The Turpial development kits
will be ready to ship as early as Q1 to all of our early supporters
so they can test them and start creating a true resilient,
decentralized, censorship-resistant mesh network.

Kudos to Luis, Jean and the rest of the team. Keep up the good work!
