Commercial Advantages

Based on Technology Leading TDK designOptimised RF design gives ~ 200m rangeVirtual Machine eliminates extra flash and processor, so

50% of cost of rival productsExcellent RF immunity from TDK Antenna design.Full Software and Firmware Support availableGuaranteed Bluetooth InteroperabilityFully Pre-Approved – no Bluetooth or RF knowledge

required from integrator.

TDK is responsible for all of the RF and Bluetooth.

Wireless becomes as simple as adding a

connector
