Overview
LISA-U1 wireless modules integrate full-feature 3G UMTS/HSxPA and 2G GSM/GPRS/EDGE protocol stack with
Assisted GPS support. These SMT modules come in the compact LISA form factor, featuring Leadless Chip
Carrier (LCC) packaging technology.

With GSM/GPRS network operation modes I to III are supported, with user-definable preferred service selectable
from GSM to GPRS. Optionally paging messages for GSM calls can be monitored during GPRS data transfer in
not-coordinating NOM II-III.
LISA-U1 series modules implement GPRS/EGPRS class 12 for data transfer. GPRS 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. Class 12 implies a maximum of 4 slots in
download (reception) and 4 slots in upload (transmission) with 5 slots in total.
The network automatically configures the number of timeslots used for reception or transmission (voice calls
take precedence over GPRS traffic). The network also automatically configures channel encoding (CS1 to MCS9).
The maximum (E)GPRS bit rate of the mobile station depends on the coding scheme and number of time slots.
Direct Link mode is supported for TCP sockets.
1
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.
2
Device can be attached to both GPRS and GSM services (i.e. Packet Switch and Circuit Switch mode) using one service at a time. If for
example during data transmission an incoming call occurs, the data connection is suspended to allow the voice communication. Once the
voice call has terminated, the data service is resumed.
3
GPRS/EDGE multislot class 12 implies a maximum of 4 slots in DL (reception) and 4 slots in UL (transmission) with 5 slots in total. GPRS 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.
