Hello i am developing a IoT product.
basically there are lot of nodes separated by 100-200metre apart. they are battery operated by 2100mah AA alkaline battery. and i want the life to be 6-8 month on each charge cycle.
The sensor node consumes 30-50ma for getting data from the sensors, and i need to tx it for 1sec every one hour, and i need a mesh kind of network,.
It seems sub GHZ will help in this scenario, still confused on which chip i should go./
Found several chips from Ti,SiLabs,Freescale,Atmel.
Anyone suggest me a best chip-set for my application. footprint doesn't matter.
