The 7 Most Common M2M Wireless Technologies: A Practical Guide
Choosing the optimal M2M/IoT wireless network can be a complex decision. A mismatch not only incurs unnecessary costs but also requires costly redesigns. Fortunately, a wealth of data and side‑by‑side comparisons can help you make a well‑informed choice.
When weighing options such as ZigBee versus a cellular M2M network, you should be able to answer a few critical questions:
- Do you require coverage across long distances?
- What is the expected battery life of your devices?
- Will you be transmitting only data, or will you also need to send control commands?
This white paper is designed to guide you through these considerations, enabling confident decisions for your IoT applications. It examines the benefits and trade‑offs of the seven most common M2M wireless technologies used today:
Below is a concise overview of each network, accompanied by typical use cases and a comparison of expected ranges when all other variables are held constant.
- WiFi
- Cellular
- Bluetooth
- Bluetooth Low Energy (BLE)
- 6LoWPAN
- ZigBee
- Symphony Link
The takeaway remains clear: there is no one‑size‑fits‑all solution for M2M wireless connectivity. If you’re developing an IoT application and need to identify the most suitable network, this white paper provides the insights you need.
