We have 2 HW variants for some products:
1) 915/868MHz
2) 433MHz
Please, always check your local regulator as the best source of information. Ask about license-free bands or ISM bands or SRD bands.
We have significantly more products in the 915/868MHz variant than in the 433MHz band. For example, Mini-RX, Super-Beacons, Industrial beacons/modem and their derivatives (Helmets, Jackets, etc.) are currently available in 915/868MHz only. So, if you can choose between 915/868MHz and 433MHz, we recommend to choose 915/868MHz.
Notice, that 433MHz or 868MHz or 915MHz is a band name – not a frequency. For example, Marvelmind HW supporting 915/868MHz band supports frequencies ~860-930MHz. It means, for example, that for Japan we recommend the 915/868MHz HW, but the real frequencies that will be used are 920.5-923.5MHz.
