The BluEpyc approach to BLE comes from a deep knowledge and habit of use of the RFID/NFC Technology, taking into account all the “old” benefits related to its use as the anti-collision feature (possibility to detect an high number of tags at the same time even if not in line of sight).
To make a decision about the ideal technology to use, in the initial phases of a project also an accurate cost evaluation has to be taken into account: where an high number of disposable tags is required, RFID Technology used in UHF band is ideal from both traceability, cost and performances point of view.
There are not tight rules, but it is all about considering every aspect of every case.
If the main requirements are instead high distance readings (i.e. 100 meters) and the monitoring of valuables or people, Bluetooth Low Energy is instead a better alternative to RFID: thanks to the easier installation of BLE devices, its native presence on smartphone and tablet and not expensive solutions, BLE could be considered in many applications.
