Activating a Wireless Card in a
Cellular Carrier Network
W
ireless connections use radiofrequencies (RF) through airwaves instead of electrical
signals through cables. Because a wireless connection obviates the need to use cables, it
allows free physical movement within the broadcast radius of a wireless access point
(AP)—for example, a cell tower. (Each wireless AP has a direct or indirect cabled connection to
the core of the wireless network.) The BANDIT can send and receive transmissions through a
wired network or a cellular wireless network.
Note: This document is for CDMA/1xRTT cards and GSM/GPRS/EDGE/UMTS/HSDPA/
HSPA cards. For EVDO cards, see Activating an EVDO Wireless Card in a Cellular Carrier Network.
5.1
Overview of Wireless Card Activation and Configuration
We recommend the following steps to activate and configure a wireless card in the BANDIT
device:
1
Activate the wireless card in the cellular carrier network.
2
Configure the card in the BANDIT menus.
3
After the card has been activated and configured (that is, when the card is ready for
operation or is in operation), use the BANDIT's statistics menus to verify the card's
configuration.
This document presents procedures for activating a cellular wireless card in its carrier network.

are for carriers within the United States, check with your local carrier for the procedure to
activate the wireless card in your BANDIT device.
Note: A cellular wireless card will not connect to the wireless carrier until the card’s
initialization has completed. In the C2C, BANDIT II C2C, and BANDIT II, cellular card
initialization takes about 30 seconds. In the BANDIT III, cellular card initialization takes
about 90 seconds.

The GSM Wireless Card
The BANDIT uses the GSM Module to provide GSM wireless connections. GSM is based on
Time Division Multiple Access (TDMA) technology. For GSM specifications, see the table
Specifications for the GSM Wireless Card in the BANDIT II and the BANDIT III.
The basic GSM card supports General Packet Radio Service (GPRS) for data transfer. The
EDGE GSM card supports Enhanced GPRS, usually known as Enhanced Data Rates for GSM
Evolution (EDGE). The BANDIT’s GSM cards also support HSPA, which can transmit voice
and data at the same time.
The protocols for GSM cards differ in transmission speeds; they are activated and configured
the same way.
See the following sections:
• Section 5.5.1, GPRS, EDGE, and HSPA
• Section 5.5.2, The GSM Card’s Subscriber Identity Module
• Section 5.5.3, Activating the GSM Card in the Carrier’s Network
• Section 7.2, Reviewing a Wireless Port’s Configuration
Also see GSM Wireless Cards.
5.5.1
GPRS, EDGE, and HSPA
The differences between GPRS, EDGE, and HSPA are in the speed and reliability for data
transmissions. The cards are activated and configured the same way. For differences, see the
table Specifications for the GSM Wireless Card in the BANDIT II and the BANDIT III.
Page 14
Wireless Set-Up Module, Document 5
The GSM wireless cards used in BANDIT devices can connect to GSM networks that use
GPRS technology, EDGE technology, or HSPA technology. You specify which technology
and carrier to use when you order a wireless card with your BANDIT device.
See the following sections:
• Section 5.5.1.1, GPRS GSM
• Section 5.5.1.2, EDGE GSM
Also see HSPA.
5.5.1.1
GPRS GSM
General Packet Radio Service (GPRS) is a packet-switched technology used for GSM. It uses
Time-Division Multiple Access (TDMA) structure and bandwidths (see the table
Specifications for the GSM Wireless Card in the BANDIT II and the BANDIT III), and supports
data speeds of up to 144 kbps.
GPRS supports IP, PPP, X.25, and many other protocols for data transmission.
5.5.1.2
EDGE GSM
Enhanced Data Rates for GSM Evolution (EDGE), also known as Enhanced General Packet
Radio Service (EGPRS), advances the evolution of the GSM standard for wireless data
transmission. EDGE enables high-speed data services over existing GSM networks, using the
same structure and bandwidths that GPRS uses (see the table Specifications for the GSM
Wireless Card in the BANDIT II and the BANDIT III).
EDGE increases data-transmission rates and improves data-transmission reliability for the
GPRS standard. The enhanced data transmission benefits video, multimedia, and similar
applications. EDGE can support any packet-switched application.
EDGE triples GSM’s data rate; in packet mode it supports 48 kbps on each of eight timeslots,
enabling throughput of 384 kbps. In theory, EDGE can support data speeds of up to 59.2 kbps
per timeslot, yielding 473.6 kbps for eight timeslots.
EDGE also transmits additional redundancy information to the recipient instead of
retransmitting disrupted packets. The recipient can use this information to improve data
reassembly.
5.5.2
The GSM Card’s Subscriber Identity Module
The GSM card supports a removable Subscriber Identity Module (SIM, also known as a GSM
smartcard), to identify the user to the GSM network. When you order your BANDIT’s
wireless card, you specify which carrier and network it will use. The SIM that has the
selected GSM carrier’s chip is indicated by that specification. You can request that the SIM
be installed before shipment, or you can choose to install the SIM when the shipment arrives.
The BANDIT is not a traveling device, so you will not need SIMs for different countries.
However, if you change GSM providers, the GSM card will need a SIM from the new
provider.
To install or change the SIM, follow the procedure in the document Changing the SIM in a
BANDIT Product’s GSM Card.
Activating a Wireless Card in a Cellular Carrier Network
5.5.3
Page 15
Activating the GSM Card in the Carrier’s Network
Before shipment or after receipt of shipment (according to the specification in your order),
the carrier’s SIM is placed into the GSM card. After the SIM has been put into the GSM card,
you must activate the card for use in the carrier’s network.
When you order a wireless card, you select a wireless carrier for your area. In the United
States, the GSM wireless cards used in the BANDIT products can connect to the following
wireless network carriers:
• Cingular/AT&T Wireless
• T-Mobile
Your wireless carrier will provide an initialization string to use when activating your
wireless card. The procedures in this section use the name I-string to represent the
initialization string.
Use the following procedure to activate the GSM card in its carrier network. Be sure to use
the initialization string provided by your carrier.
• How to Use AT Commands to Activate a GSM Card in Its Carrier Network
Note: The activation procedure listed above includes registration, so you do not need to
perform the registration procedure as a separate process. However, if you wish to use the
BANDIT’s ELIOS software to register the GSM card in its carrier network as a separate
process, use the following procedure.
