The module read level on the sensor every hour and memorize it. After 12 hour (12 reading) the module transmit a radio data frame with the level history of the last 12 hours to à C@llRider®. A C@llRider® is another part of the system that receive the data and then connect to internet and send the data over the net to the servers. 2.2 Hardware specifications 2.2.1 Mechanical specifications The electronic part is housed in a specific casing.

The Frequency hope spread spectrum (FHSS) scheme was retained to achieve it. The FHSS principal is: Transmitting on one frequency for a certain time, then pseudo-randomly jumping to another, and transmitting again. Also, the FHSS could counter-act interference by using different carrier frequency at different time. It's carrier will hop around within the band so that hopefully it will avoid the jammer at some frequencies. To synchronize the transmission and reception frequency, in order to prevent lost data, a sync word has been inserted. Also, to assure completion of all the data, an algorithm of data interleaving and data correction have been implemented. 3.1.2 Structure Simplified OSI structure: ------------------------------------------------------------------ HR_Interface ------------------------------------------------------------------ LLC_Interface ------- MAC_Interface ------------------------------------------------------------------ PHY_Interface 2.

Each burst consists of 48 chips (24bits). And for each burst, there’s a frequency hope Î 64 bursts for 64 frequencies. The beacon burst is composed of a preamble and a long sync word 2/ Data sub-frame The data sub-frame is composed of 64 bursts. Each burst consists of 48 chips (24bits). And for each burst, there’s a frequency hope Î 64 bursts for 64 frequencies. The data burst is composed of a preamble, short sync word and 16 bits of data. séquence 1 2 3 4 5 61 62 63 64 1 2 3 4 5 61 burst baliseburst donnéfréquence 52 63 3 35 12 27 47 20 33 52 63 3 35 12 27 4séquence balise séquence donnée

After 12 hours, the module activate the radio to send a data frame with the last 12 hours inside. After the system return to sleep for one hour waiting the time for the next measure.
