1.1 Overview

The LISA-U1/LISA-H1 series is a family of SMT wireless modules featuring Leadless Chip Carrier (LCC) packaging

and integrating a full-feature 3G UMTS/HSxPA and 2G GSM/GPRS/EDGE protocol stack with A-GPS support.

 Band I (2100 MHz) and Band VIII (900 MHz) for LISA-U110, LISA-U130, LISA-H110

 Power Class 3 (24 dBm) for WCDMA/HSDPA/HSUPA mode

 HSUPA category 6, up to 7.2 Mb/s DL, 5.76 Mb/s UL (LISA-U1 series only)

 HSDPA category 8, up to 7.2 Mb/s DL, 384 kb/s UL (LISA-U1 series only)

 HSDPA category 6, up to 3.6 Mb/s DL, 384 kb/s UL (LISA-H1 series only)

 WCDMA PS data up to 384 kb/s DL/UL

 WCDMA CS data up to 64 kb/s DL/UL

GSM/GPRS/EDGE characteristics:

 EDGE Power Class E2 (27 dBm) for GSM/E-GSM bands

 EDGE Power Class E2 (26 dBm) for DCS/PCS bands

 EDGE multislot class 12

, coding scheme MCS1-MCS9, up to 236.8 kb/s

 CSD Non-transparent / Transparent Mode, up to 9.6 kb/s

As a 3G module the LISA-U1/LISA-H1 series module is Class A User Equipment: the device can work

simultaneously in Packet Switch and Circuit Switch mode. This means that voice calls are possible while the data

connection is active without any interruption in service.

As a 2G module the LISA-U1/LISA-H1 series module is Class B Mobile Station: the 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 instance, if

during data transmission an incoming call occurs, the data connection is suspended to permit the voice

communication. Once the voice call has terminated, the data service is resumed. 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/LISA-H1 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.

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.
