HI TO ALL.
I WANT TO USE CC1101 IN MY PROJECT,WHICH IS A SMALL SYSTEM FOR TELEMETRY,ALARM AND DATA TRANSMISIONS,AT 433 MHZ OR 868 MHZ.I KNOW THAT THIS SPACE IS NOT THE RIGHT ONE ,BUT I WANT TO ASK:
1.WHEN ETSI EN 30 220 SAYS THAT :FOR DUTY CYCLE 1,0%,MAX "ON" TIME IS 36s PER HOUR,WHAT DOES IT MEANS? THAT THE TOTAL "ON " TIME IS 36s PER HOUR AND CAN I TRANSMIT,FOR EXAMPLE 2400 TIMES FOR 15ms PER EACH TIME?
2.WHEN ETSI EN 30 220 SAYS THAT :FOR DUTY CYCLE 1,0%,MIN "OFF"TIME IS 1,8s PER HOUR,WHAT DOES IT MEANS? IS THIS THE STANDARD "OFF" TIME,OR IT IS DEPENDING OF THE "ON" TIME?
3.IN YOUR OPINION,WHICH ONE TYPE OF MODULATION, THAT CC1101 CAN USE,IS THE BETTER? (@38.4 KBPS)
4.AND WHICH ONE FREQUENCY IS BETTER TO USE 433 OR 868 MHZ? OR SOMEONE ELSE FREQUENCY?
5.25 KHZ BANDWIDTH IS OK?
6.WHAT TYPE OF ANTENNA HAVE I TO USE ,ACCORDING TO THE REGULATIONS OF ETSI?
I AM USING SMARTRF STUDIO 7.
HOPE THAT SOME ONE CAN HELP ME.
MY BEST REGARDS.
