CC1310: 169MHz band support

Hi Albin,

There are no plans for CC1310 for 169 MHz.

169 MHz is typically narrowband so recommend the combination MSP430+CC1120 or an offering with BLE support as well: CC2640R2 + CC1120.

What is the requested maximum output power ?

CC1310 does not support 169 MHz, CC1312 is designed to cover this band but settings will not be provided before some time after RTM.

tx power is not defined, still under investigation.
use case is in US market, they hope it can reach 1m under water surface.
do you think it is possible?

No. Please do a google search for "RF underwater" or similar. To communicate with RF under water you need a lot lower frequency.

Hi Albin,

Have not worked with 169 MHz in the US but only in Europe and South America.

Attenuation in underwater channels increases exponentially with frequency. In order to have a chance to achieve the distance, the datarate must be low. Which regulatory standard are you targeting ?

Is the water fresh water or sea water ?

Ideal if you can reduce the frequency as much as possible.

At 169 MHz, I would estimate a loss in the region of 80 dB for approx 1m. at 169 MHz. So it is feasible.

Antenna size ?

Hi Richard,

They bought antenna from Mouser. The chip they current use is AX5043, cheaper than our CC1120. So I hope I can use CC1310 to replace it.

The project is for swimming pool lighting. They use to control the light under water.

Do you have any plan to support this 169 MHz frequency for CC1310 or CC1312?
