Usually we need to confirm where are the customer from. Then we need to confirm what do you use the wireless system for?
If you are noT sure about your local limited on the wireless tour guide system, we will advice the 2.4G system.
As we all know, the 2.4GHz is a frequency band operating in the ISM band. The ISM band is an industrial, scientific and medical band. Generally speaking, countries around the world have reserved some wireless frequency bands for industrial, scientific research, and microwave medical applications. No license is required to apply these frequency bands, you only need to observe a certain transmit power (generally less than 1W), and do not cause interference to other frequency bands.
ISM band regulations are not uniform in many countries, butthe 2.4GHz is the ISM band common to all countries. Therefore, wireless LAN (IEEE (802.11b / IEEE 802.11g), Bluetooth, ZigBee and other wireless networks can work in the 2.4GHz band.
