1
LARA-R2 series modules support all the E-UTRA channel bandwidths for each operating band according to 3GPP TS 36.521-1 .
2 GPRS/EDGE multi-slot class determines the number of timeslots available for upload and download and thus the speed at which data can
be transmitted and received, with higher classes typically allowing faster data transfer rates.
3
GPRS/EDGE multi-slot class 12 implies a maximum of 4 slots in DL (reception) and 4 slots in UL (transmission) with 5 slots in total.
4 Not supported by LARA-R204 module "02" product version.
