Radiocrafts is eager to share this new exciting video released by the University of Cardiff on the Cryoegg, an egg-shaped device with a Radiocrafts module inside which is able to measure melting water up to 1.5 kilometres beneath the ice sheet of a glacier in Greenland.
The 169 MHz band allows for good performance in terms of coverage, penetration, and consumption of battery, while still ensuring a sufficient bitrate. This is important in applications where propagation conditions are poor. Radiocrafts has seen a rise in popularity for the RC1701HP-MBUS4 module because it can be used in various applications where a device is placed in a “hard-to-reach” location and where propagation conditions are poor. Two notable and innovative solutions include using a Cryoegg to measure the water behaviour beneath the surface of a glacier, and, a new tank level measurement device from Alisonic for petrol tanks buried 1-meter underground. You can read about the Alisonic tank level measurement device here.

The RC1701HP-MBUS4 has built in support for antenna tuning, and we have released an application note AN025: Tuning the Antenna with Antenna Tuning Feature, to help our customer to create their own tuned 169 MHz antenna.
