Which modem supports low-latency links in a power-constrained environment?

A software-defined modem (SDM) is often the best fit for low-latency links in a power-constrained environment, because it can be optimized to meet latency requirements while managing power use efficiently.

If you mean which type of modem specifically, look for one that is:

• low-power
• supports real-time/low-latency operation
• adaptive (so it can reduce power when link demand is lower)

If you want, I can also help narrow it down by wireless vs. wired, or by a specific platform like LTE/5G, satellite, or IoT.
