Hello All:
Anyone has experience using Xbee 868 modem in an area where GSM 900MHz cellphone-band is used? I m wondering whether there will be severe interference problem since 868MHz is quite near to 900MHz?
Another problem is is XBee 868 really with that super long range (I mean, 4Km)? I did a test and seems around 1km, signal strengh is already obviously reduced.
Thank you for all suggestions.
Alex
