Does the 4G Analyser work outside of the EU?
Yes.
For North America, we have the CS2389-NA version.
For Australia, we have the CS2389-AU version.
For any other country, the easiest way to find out if the 4G Signal Analyser will work is to Google the Radio Frequency Bands for a country and then check the Frequency Band table on the last page of the Signal Analyser Quick Guide. If the Signal Analyser has matching Band Frequencies, then it will work in that Country.
