8.1 GSM/GPRS module (GSM6H), type 67-0Z The GSM/GPRS module functions as transparent communication path between reading software and MULTICAL® 801 and is used for data reading. The module includes an external dual-band GSM antenna which must always be used. The module itself includes a line of light emitting diodes indicating signal strength which are very useful during installation. Further details about the GSM/GPRS module appear from data sheet (DK: 5810627, GB: 5810628, DE: 5810629, SE: 5810630). 8.2 3G GSM/GPRS module (GSM8H), type 67-0U Like GSM6H this module functions as transparent communication path between reading software and MULTICAL® 801 and is used for data reading. However, this module supports both 2G (GSM/GPRS) and 3G (UMTS) which makes it applicable in areas with 3G coverage only. The module requires an external Antenna, which covers both 900 MHz, 1800 MHz and 2100 MHz. The module itself is fitted with a line of light emitting diodes indicating signal strength which are very useful during
