Bluetooth or WLAN - Which do I choose?

One wireless technology cannot cater for all application requirements. The standardised wireless technologies — WLAN, Classic Bluetooth and Bluetooth Low Energy — are good at different things.

HMS Industrial Networks are experts in all types of communication technologies and have created this short article to give you some further information about which wireless technology will be best for you.

WLAN (also commonly referred to as WiFi) is the most widely used wireless standard. It is often used for production planning and data acquisition as well as applications where rapid roaming is required. It provides very high data throughput but it's long wavelength makes it vulnerable to disturbance.


Bluetooth is often used for Human Machine Interfaces (HMI), programming, service/maintenance and real-time control tasks. It has a narrow band frequency spectrum which, together with functionality such as: Adaptive Frequency Hopping (AFH), makes it less sensitive to disturbances.

Bluetooth Low Energy

During the last few years, other technologies like Bluetooth Low Energy technology have become increasingly used for sensors, actuators and other small, often battery-driven, devices that need to be interconnected.
