We use TTN Mapper for testing of availability of our network service. TTN Mapper is a simple way how to test the network with a smartphone (Android or iOS) and a simple RF sensor (used e.g. Arduino UNO and RN2483 as an RF “beacon”). The output can be found at https://ttnmapper.org/
The measurement of our network was run in 3 weeks in Nov. and Dec. 2017. It was made by our students widely across Ostrava city.
