When building advanced wireless systems, developers often are faced with choosing between two ISM radio band options: 2.4 GHz or sub-GHz. In recent years, there has been a growing interest in sub-GHz frequencies thanks to its longer range, lower power consumption, and better penetration through walls or other obstacles.
Sub-GHz wireless networks can provide an extremely cost-effective solution in any low-data-rate system, from simple point-to-point connections to much larger mesh networks, where long range, robust radio links and extended battery life are leading priorities.
This selector guide includes:
