Activating a Wireless Card in a Cellular Carrier Network Wireless 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. See the following sections: Section 5.2, Activating a Card in the Carrier s Wireless Network - Section 5.2.1, Automatic Activation in the Carrier s Wireless Network - Section 5.2.2, Activation via AT Commands in the Carrier s Wireless Network Section 5.3, The EVDO Wireless Card Section 5.4, The CDMA Wireless Card - Section 5.4.1, Activating the CDMA Card in the Carrier s Network For information on trademarks, safety, limitations of liability, and similar topics, see Notices.

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 Page 15 5.5.3 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. How to Use Automatic Activation for a GSM Card How to Use Automatic Activation for a GSM Card Note: Before you activate the module in the network, make sure the module has already been properly provisioned for your network.
