Zigbee or really any Bluetooth alternative.
Bluetooth is a poorly engineered protocol. It jumps around the spectrum while transmitting, which makes it difficult and power intensive for bluetooth receivers to track.
I agree Bluetooth (at least Bluetooth Classic) is not very well designed, but not because of frequency hopping. That improves robustness and I don't see why it would cost any more power. The hopping pattern is deterministic. Receivers know in advance which frequency to hop to.
