If you're viewing it online, simply click a topic in the Table of Contents, or a page number in the Index, or any page reference or section reference. (Most text that is blue is a clickable link.) The PDF automatically displays the appro-priate page.Feature summaryNote: For step-by-step instructions to access features of the modem, consult the online help available with the Watcher® software (page 28).The USB modem is designed to provide a wide range of capabilities using CDMA and WiMAX network technology. Implementation of these features depends on the particular service provider and account features you have chosen.

AirCard 250U Modem - User Guide10 2131331Some features described in this manual may not be supported by your service provider or may not be available with your network account. For details of the services and accounts available, contact your service provider.Wireless modemOnce installed and configured, the modem can connect to the CDMA network or WiMAX network automatically. You just insert the modem, allow Watcher to autolaunch and authenticate your account on the network, then launch your Internet browser (which you can also configure in Watcher to launch automatically)—you’re online!Alternatively, you can make a high-speed data connection without running Watcher—simply by launching whatever application you want to use (such as your web browser or e-mail application). For details, see the online help topic “Autoconnect behaviour”.The modem also allows you to dial up a modem (such as a corporate server).TRU-InstallTRU-Install™ is a Sierra Wireless feature that installs the necessary software and drivers the first time you insert the modem into your computer. An installation CD is not required.TRU-LocateWith TRU-Locate™, you can use location-based services (GPS) to query, for example, the network for information on points of interest (POI) that are near your current location, or display driving instructions.Note: TRU-Locate is subject to feature availability.Your modem requires an unobstructed view of GPS satellites (in the sky), and, like any other GPS device, might not perform well within forested areas or near tall buildings.Depending on your account, you may be charged for each position fix or after you have performed a certain number of fixes. For details, contact your service provider.Depending on the mechanism that the network and your modem use to obtain location information, GPS may not be supported:•If Network Mode is set to “EVDO Only”•If you're roaming•If you do not have network coverage•Due to other reasons.If you’re having problems using GPS, contact your service provider.

Rev 1.0 May.10 11CDMA 3G servicesThe modem can operate over a type of wireless network called CDMA (Code Division Multiple Access).CDMA 3G technology provides a variety of connectivity features, depending on your service provider and account:•1x-EVDO Rev. A supports Internet connections with data rates up to 3.1 Mbps (downlink from the network) and 1.8 Mbps (uplink to the network). Average data rates are 450-800 Kbps (downlink from the network) and 300-400 Kbps (uplink to the network). Actual speed depends on the network conditions.•1x-EVDO Rev. 0 supports Internet connections with data rates up to 2.4 Mbps (downlink from the network) and 153 Kbps (uplink to the network). Average data rates are 400-700 Kbps (downlink from the network) and 40-80 Kbps (uplink to the network). Actual speed depends on the network conditions.•1X supports Internet connections with data rates up to 153 Kbps. Actual speed depends on the network conditions.Once the connection is established, you can open your browser and connect to any web site that is accessible through the Internet, or access other Internet services (such as e-mail).The connection is “active” when data transmission is occurring. If data transmission stops for a period of time (determined by the network), the connection becomes dormant.•Circuit switched (dial-up) data, using the earlier CDMA IS-95 specification, supports data connections to any dial-in service at rates up to 14.4 Kbps.•QNC (Quick Net Connect) provides a simplified way to dial into an Internet connection (using circuit switched data) where 3G (1xEV-DO or 1X) high-speed packet service is not available.•SMS (Short Message Service) allows you to send and receive short text messages using the modem.Watcher auto-updateChoose to have the latest features and updates for your modem and Watcher software installed automatically.

Updates can be over Ethernet or WiFi to save WWAN overlimit or roaming charges.•Keeps your firmware, drivers and Watcher software up to date.•Allows you to set a specific schedule that can be set to check for updates such as daily, weekly, monthly or not at all.•On demand manual checks can also be completed.•A download pause-and-resume capability pauses the update download when your computer is in use and resumes it during idle time so the user experience isn’t affected.•Updates can be over any connection—not just the WWAN connection.

AirCard 250U Modem - User Guide12 2131331Additional features of the modemBeyond the features of the CDMA network and WiMAX network, the modem provides additional software features:•PIN security code to protect your modem and account from unauthorized use.•A wizard to assist with activating your CDMA account.•Sound options to customize ringtones for SMS messages.•A Call Log to track outgoing calls and determine the amount of data trans-ferred.Package contentsYour package contains the following items:•AirCard 250U modem•Quick Start Guide•Carry pouchTo install the modem drivers and software, you do not need an installation CD. Your modem uses the Sierra Wireless TRU-Install feature. The drivers and software are installed when you insert the modem into your computer and go through the software installation; an installation CD is not required.System componentsYour modem is just one part of a system designed to provide you with a wide range of communication features. Every component of the system is needed to enable these capabilities.Your host computing deviceYour notebook or desktop computer hosts the modem hardware and runs the communication software: your web browser or e-mail application, and Watcher—the enabling software for the modem.You may also have other software on your computer that can be used wirelessly with the modem, such as: file transfer applications (FTP), chat or instant messaging, a VPN (Virtual Private Network) client, client software for a corporate server application.The USB modemThe modem provides your computer with a connection to the CDMA or WiMAX wireless network.The modem fits into a USB slot available on most notebook and desktop computers.

Rev 1.0 May.10 13Every CDMA network operates on one of three radio frequency bands. As a dual-band product, the modem operates on two of these bands (see page 32), providing a wide coverage area.The modem drivers and enabling softwareThe modem drivers and enabling software (Watcher) monitor and manage your wireless connections.Your modem uses the Sierra Wireless TRU-Install feature—the drivers and software are installed when you insert the modem into your computer.The device driver software enables the modem to work with your computer’s operating system.Using the Watcher software, you can manage the modem and monitor your connections.For step-by-step instructions to access features of Watcher, use the application’s online help.CDMA service provider accountCompanies that operate CDMA networks and provide access to these networks are called service providers. To use the modem, you must have an account with a CDMA service provider.Note: You can use the Lock Modem feature to prevent others from using your account, should your modem be stolen.Each service provider has its own pricing options. There may be flat rate accounts, which provide you a maximum number of minutes of network usage for a fixed monthly fee. There may be accounts for which you are charged for network usage by the minute or by the amount of data transmitted.Your account may include a variety of other services such as SMS messaging or location-based services.Each modem has been provisioned at the factory for use with a particular service provider. This sets the modem to use particular radio channels and enables services specific for that provider.The process of setting up your account is called activation. Activation involves action by the service provider and configuration of the modem.The procedure to configure (activate) your modem is covered in Activation on page 21.The CDMA wireless networkNote: More information about CDMA networks is available on the CDMA Development Group web site, www.cdg.org.This is the worldwide infrastructure providing the radio coverage that allows you to stay connected. Made up of radio towers and a variety of network switches, routers, and servers, the network is an interconnection of many service providers.

AirCard 250U Modem - User Guide14 2131331Note: Most service providers have coverage maps on their web sites.There are CDMA networks that operate in the frequency bands supported by the modem throughout North America and parts of Latin America, Asia, and New Zealand. However, each service provider operates a network that covers a limited geographical area within the overall CDMA coverage area.Note: The fee for service is usually higher when you are roaming (connecting to a network other than the one belonging to your service provider).Most service providers have “roaming” agreements with other service providers, so that they can offer service outside of the coverage area of their own networks. For example, assuming you live in Vancouver (Canada), and travel frequently to Seattle (United States), you can obtain an account with a Vancouver service provider that has a roaming agreement with a service provider in Seattle. You would then have local service in Vancouver, and roaming service in Seattle.Care and maintenance of your modemAs with any electronic device, the modem must be handled with care to ensure reliable operation. Follow these guidelines in using and storing the modem:•The modem should fit easily into your USB slot. Forcing the modem into a slot may damage connector pins.•When inserting or removing the modem, always grip it by the sides rather than the end.•Protect the modem from liquids, dust, and excessive heat.•When not installed in your computer, store the modem in a safe place.
