Technically I don't think it is an SDR, as it's not using software to generate arbitrary modulation schemes. The chip is capable of transmitting data through certain modulations.

http://www.ti.com/corp/docs/landing/cc1111/ - is the chip they're using.

Yes, it is not a SDR because CC1111 doesn't send the I/Q samples, so no custom demodulation possible. Only support some standard modulation AM/FM/FSK, ...
