5
Device can work simultaneously in Packet Switch and Circuit Switch mode: voice calls are possible while the data connection is active
without any interruption in service.
6 Device can be attached to both GPRS and GSM services (i.e. Packet Switch and Circuit Switch mode) using one service at a time. For
example, if an incoming call occurs during data transmission, the data connection is suspended to allow the voice communication. Once the
voice call has terminated, the data service is resumed.
7 SARA-U260 and SARA-U270 modules do not support 8-PSK modulation in uplink; the EDGE Power Class corresponds to the GSM/GPRS
Power Class
8 The maximum bit rate of the module depends on the actual network environmental conditions and settings.
9
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.
10 GPRS multi-slot class 12 implies a maximum of 4 slots in DL (reception) and 4 slots in UL (transmission) with 5 slots in total.
11
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.
12
SARA-U260 and SARA-U270 modules support EDGE multi-slot class 12: MCS1-MCS9 up to 236.8 kbit/s DL, MCS1-MCS4 up to 70.4 kbit/s
UL
13
GPRS multi-slot class 10 implies a maximum of 4 slots in DL (reception) and 2 slots in UL (transmission) with 5 slots in total.
