Uniden Data 2000 Introduction

RAISE ANTENNA

Caution - Before operating this device, be sure to place the antenna in
the vertical position. This offers the best performance of your modem, and, at the same time, reduces the risk of possible exposure to electromagnetic radiation emanating from the antenna. The antenna must be maintained at least 4 inches (or 10 cm) from users and nearby persons to comply with FCC radio frequency exposure limits (and to reduce the risk of RF radiation) when the Uniden Data 2000 is in operation.

Uniden Data 2000 Installation and Operation Manual
1.1 What is the Uniden Data 2000?
The Uniden Data 2000 is a wireless CDPD (Cellular Digital Packet Data) PC Card which enables most laptops, hand held computers, and Personal Digital Assistants with Type II PC Card slots to communicate with host-based applications such as web servers, intranet servers, databases, dispatch systems, and other host computer systems. The Uniden Data 2000 uses the Internet suite of protocols running over the CDPD system. The product is fully Windows compatible, supporting Windows 95/98, Windows NT, and Windows CE. It includes a suite of GUI (Graphical User Interface) utilities to provide the user with simplified access to operational status and statistics, as well as the ability to configure, control, and monitor the performance of the device. The Uniden Data 2000s compact size makes it an easily portable communications tool that can be stored conveniently in a briefcase or purse when not in use.

1.2 What is CDPD?

CDPD or Cellular Digital Packet Data is a wireless, public access, packet data standard designed to operate over existing analog cellular phone systems. Since it is designed to use existing cellular phone systems, CDPD provides a large coverage area. CDPDs primary benefit is quick, inexpensive, and efficient transmission of data packets. Additional benefits include built-in encryption for security (where applicable); a billing structure which charges for message size rather than on-line time (depending on individual service providers service plans); forward error correction methods that reduce the effects of noise and interference on the airlink; and widespread deployment.

Setting up the Wireless AP
The WNP1000 802.11b Access Point is configured to work with your cable/dsl router, switch or hub and other 802.11b wireless products directly out of the box. There is no need for you to configure your Access Point, unless you want to enable increased security (WEP), change the IP Address, or other configuration options. If you want to change the default configurations, you will need to access the browser-based utility of the WNP1000 Wireless AP, you need a computer with the TCP/IP protocol enabled and web browser software (Microsofts Internet Explorer, Netscape, etc.). In order for your computer to communicate with the WNP1000, both (your computer and the AP) will need to be on the same Local Area Network, i.e. they must have similar IP Addresses. The default IP address of the WNP1000 Wireless AP is http://192.168.1.10. As a result, your PCs IP Address should be on the same network (i.e., at a LAN IP Address such as 192.168.1.2, 192.168.1.3, etc.) Note: If you are having trouble communicating with your Access Point, please see Troubleshooting on page 37.

WLAN Setup

You are now ready to begin setting up the wireless portion of your network. Click WLAN Setup on the menu, and the following page will appear.
Set each of the parameters on this page as desired, and click Apply. The parameters are described in more detail below SSID: The Service Set Identifier (SSID) is a 32-character, casesensitive field that identifies your WNP1000 Wireless AP and wireless network to wireless clients that support the IEEE802.11b wireless standard. You should use a unique SSID to control access to your private network, and to prevent conflicts with other wireless networks that may be nearby. The WNP1000 Wireless AP is configured with a default SSID of UNIDEN. Note: All clients on the same wireless LAN must have the same SSID. If you change the SSID on the WNP1000 Wireless AP, you must change the SSID for each computer and/or device you are wanting to connect using the 802.11b wireless network.
Channel: Channels are the spectrum range where your wireless signals are transmitted. The default is channel 1. However, to maximize performance for your wireless network, another channel may give you better performance. Select the channel you wish to use from the pull-down menu. Note: For better performance, avoid using channels occupied by other APs in the area.
WEP Encryption To make your network more secure, you may choose to use Wired Equivalent Privacy (WEP). WEP is an encryption scheme used to protect your wireless data communications. WEP uses a combination of 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmission. The WNP1000 Wireless AP supports both 64-bit WEP and 128-bit WEP. To decode a data transmission, each point in a network must use an identical 64bit or 128-bit key. In simple terms, a 128-bit key will give you a more secure network than a 64-bit key. Note: Some products refer to 64-bit encryption as 40-bit encryption. Both are names for the same encryption technology. 802.11b clients inserted into your laptop or desktop computer must have the same WEP settings as the AP in order for them to communicate with each other.

WEP Key Configuration WEP keys either can be entered manually, or can be generated by using a simple-to-type passphrase. Passphrase Method When you enter a passphrase, the WNP1000 Wireless AP generates four WEP keys for you. You can generate those same WEP keys on any wireless client whose configuration utility supports passphrases. To setup WEP using a passphrase, perform the following steps. 1. Select either 64-bit or 128-bit WEP encryption from the pull-down menu. 2. Click on Auto (Generated from passphrase). 3. Type a passphrase of up to 31 alphanumeric characters into the Passphrase field and click Generate to create the hex key(s). 4. Select the active WEP key set (1, 2, 3, or 4) for 64-bit encryption. WEP 128-bit encryption creates only one key. Verify that you are using the same active key for all clients on your wireless network. (If a client does not support passphrases, you may manually enter the desired key on that client.) 5. Click Apply. Remember that changes do not take effect until after you restart your WNP1000 Wireless AP by clicking the Reboot button.
A sample WEP configuration using a passphrase is shown in the following figure.
Manual Key Entry To manually enter the WEP keys, perform the following steps: 1. Select either 64-bit or 128-bit WEP encryption from the pull-down menu. 2. Click on Manual (Enter in the table below). 3. When WEP 64-bit is selected, type five alphanumeric characters in the range of a-z, A-Z and 0-9 (e.g. MyKey) in the WEP Key 1 entry field. Alternatively, you may enter 10 digit hexadecimal values in the range of A-F and 0-9 (as shown in the example below). You can also enter WEP keys in the Key 2, Key 3 and Key 4 if you wish. Select the active WEP key set (1, 2, 3, or 4) for 64-bit encryption. WEP 128-bit encryption uses only one key. Verify that you are using the same active key for all clients on your wireless network. 4. Click Apply. Remember that changes do not take effect until after you restart your WNP1000 Wireless AP by clicking the Reboot button.
A sample WEP configuration using manual key entry is shown in the following figure.

WLAN Access Control

When you click WLAN Access Control the following page will appear.
MAC Address Access Control In 802.11b, the MAC Address may be used as a means to control network access. If you choose Disable MAC Address Access Control, all clients within range of your Access Point can access your WNP1000 Wireless AP and its associated network if you dont use other means of protection (such as WEP). To enable MAC Address Access Control, click on Enable and then click Apply. Click on Allow (beside Access Control Mode). Next, enter a list of MAC addresses of clients that you wish to allow on your network. To do so, click Add and type in the MAC Address of each client in the pop-up page as shown in the following figure.

Download - To receive a file transmitted over a network. In a communications session, download means receive, and upload means transmit. Driver - A software module that provides an interface between a network interface card and the upper-layer protocol software running in the computer; it is designed for a specific adapter, and is installed during the setup of the adapter. DSSS (Direct-Sequence Spread-Spectrum) - DSSS generates a redundant bit pattern for each bit transmitted. This bit pattern is called a chip (or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. Dynamic IP Address - An IP address that is automatically assigned to a client station in a TCP/IP network, typically by a DHCP server. Network devices that serve multiple users, such as servers and printers, are usually assigned static IP addresses. Dynamic Routing - The ability for a router to forward data via a different route based on the current conditions of the communications circuits. For example, it can adjust for overloaded traffic or failing lines and is much more flexible than static routing, which uses a fixed forwarding path. Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Has a transfer rate of 10 Mbps. Forms the underlying transport vehicle used by several upper-level protocols, including TCP/IP and XNS. Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet CSMA/CD network access method. Firewall A firewall is a set of related programs, located at a network gateway server, which protects the resources of a network from users from other networks. (The term also implies the security policy that is used with the programs.) An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources to which its own users have access. A firewall, working closely with a router, examines
Firmware - Programming that is inserted into programmable read-only memory, thus becoming a permanent part of a computing device. Flash Memory - Flash memory is an electronic storage device capable of recording several megabytes of data files. Fragmentation - Breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet. Hardware - Hardware is the physical aspect of computers, telecommunications, and other information technology devices. The term arose as a way to distinguish the box and the electronic circuitry and components of a computer from the program you put in it to make it do things. The program came to be known as the software. Hub - The device that serves as the central location for attaching wires from workstations. Can be passive, where there is no amplification of the signals; or active, where the hubs are used like repeaters to provide an extension of the cable that connects to a workstation. IEEE (Institute of Electrical and Electronics Engineers) - The IEEE fosters the development of standards that often become national and international standards. The organization publishes a number of journals, has many local chapters, and has several large societies in special areas, such as the IEEE Computer Society. IEEE 802.11 - Industry standard that enables wireless LAN hardware from different manufacturers to communicate. Infrastructure Mode - A mode of operation of the 802.11b wireless protocol that allows all computers on a wired and wireless network to share a peripheral, such as a printer or high speed Internet Access. IP Address - In the most widely installed level of the Internet Protocol (IP) today, and IP address is a 32-binary digit number that identifies each sender or receiver of information that is sent in packets across the Internet. When you request an HTML page or send e-mail, the Internet Protocol part of TCP/IP includes your IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the e-mail address youre sending a note to. At the other end, the recipient can see the IP address of the Web page requestor or the e-mail sender and can respond by sending another message using the IP address it received.

IPCONFIG A utility that provides for querying, defining and managing IP addresses within a network. This utility is commonly used under Windows NT and 2000, for configuring networks with a static IP address. IPSec (Internet Protocol Security) - A developing standard for security at the network or packet-processing layer of network communication. A big advantage of IPSec is that security arrangements can be handled without requiring changes to individual user computers. IRQ (Interrupt Request) A hardware interrupt on a PC. There are 16 IRQ lines used to signal the CPU that a peripheral event has started or terminated. Except for PCI devices, two devices cannot use the same line. ISP (Internet Service Provider) - A company that provides individuals and companies access to the Internet and other related services such as website building and virtual hosting. LAN (Local Area Network) A group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building). Latency - The time delay between when the first bit of a packet is received and the last bit is forwarded. Link Quality - The quality of data being received. MAC Address (Media Access Control Address) - A unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. Mbps (Megabits per Second) One million bits per second; a unit of measurement of the speed of data transmission. NAT (Network Address Translation) The translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside. Network - A system that transmits any combination of voice, video, and/or data between users.
NIC (Network Interface Card) A board installed in a computer system, usually a PC, to provide network communication capabilities to and from that computer system. Also called an adapter. Packet Filtering - Discarding unwanted network traffic based on its originating address or range of addresses or its type (e-mail, file transfer, etc.). PCI (Peripheral Component Interconnect) A peripheral bus commonly used in PCs, Macintoshes and workstations. It was designed primarily by Intel and first appeared on PCs in late 1993. PCI provides a high-speed data path between the CPU and peripheral devices (video, disk, network, etc.). There are typically three of four PCI slots on the motherboard. In a Pentium PC, there is generally a mix of PCI and ISA slots or PCI and EISA slots. Early on, the PCI bus was known as a local bus. PCI allows IRQs to be shared, which helps to solve the problem of limited IRQs available on a PC. For example, if there were only one IRQ left over after ISA devices were given their required IRQs, all PCI devices could share it. In a PCI-only machine, there cannot be insufficient IRQs, as all can be shared. PCMCIA - The PCMCIA (Personal Computer Memory Card International Association) is an industry group organized in 1989 to promote standards for a credit card-size memory or I/O device that would fit into a personal computer, usually a notebook or laptop computer. Peer-to-Peer Networking Allows users to share local resources between PCs without needing an access point or router. Ping (Packet Internet Groper) An Internet utility used to determine whether a particular IP address is online. It is used to test and debug a network by sending out a packet and waiting for a response. Plug-and-Play The ability of a computer system to configure expansion boards and other devices automatically without requiring the user to turn off the system during installation. Port A pathway into and out of the computer of a network device such as a switch or router. For example, the serial and parallel ports on a personal computer are external sockets for plugging in communications lines, modems, and printers. PPPoE (Point to Point Protocol over Ethernet) A method used mostly by DSL providers for connecting personal computers to a broadband modem for Internet access. It is similar to how a dial-up connection works but at higher

PPTP (Point-to-Point Tunneling Protocol) A protocol (set of communication rules) that allows corporations to extend their own corporate network through private tunnels over the public Internet. Effectively, a corporation uses a widearea network as a single large local area network. A company no longer needs to lease its own lines for wide-area communication but can securely use the public networks. This kind of interconnection is known as a virtual private network (VPN). Print Server - A hardware device that enables a printer to be located anywhere in the network. RIP (Routing Information Protocol) A simple routing protocol that is part of the TCP/IP protocol suite. It determines a route based on the smallest hop count between source and destination. RIP is a distance vector protocol that routinely broadcasts routing information to its neighboring routers and is known to waste bandwidth. AppleTalk, DECnet, TCP/IP, NetWare, and VINES all use incompatible versions of RIP. RJ-11 (Registered Jack-11) A telephone connector that holds up to six wires. The RJ-11 is the common connector used to plug a telephone into a wall. RJ-45 - A connector similar to a telephone connector that holds up to eight wires, used for connecting Ethernet devices. Router - Protocol-dependent device that connects sub networks together. Routers are useful in breaking down a very large network into smaller sub networks; they introduce longer delays and typically have much lower throughput rates than bridges. Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services. Signal Strength The amount of electromagnetic energy is present. A receiver (such as the one in your access point determines the strength of the signal for each wireless channel. Software Instructions for the computer. A series of instructions that performs a particular task is called a program. The two major categories of software are system software and application software. System software is made up of control programs such as the operating system and database management system (DBMS). Application software is any program that processes data for the user. A common misconception is that software is data. It is not, software tells the hardware how to process the data.
SOHO (Small Office/Home Office) Market segment of professionals who work at home or in small offices. Static IP Address - A permanent IP address that is assigned to a node in a TCP/IP network. Static Routing - Forwarding data in a network via a fixed path. Static routing cannot adjust to changing line conditions as can dynamic routing. Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP address to form part of the host ID address field into a field for subnets. Switch 1. A data switch connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connections in an electrical circuit. TCP (Transmission Control Protocol) A method (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP keeps track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet. TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic communication language or protocol of the Internet. It can also be used as a communication protocol in a private network (either an intranet or an extranet). When you are set up with access to the Internet, your computer is uses the TCP/IP protocol. TFTP (Trivial File Transfer Protocol) A version of the TCP/IP FTP protocol that has no directory or password capability. Throughput - The amount of data moved successfully from one place to another in a given time period. Topology - A networks topology is a logical characterization of how the devices on the network are connected and the distances between them. The most common network devices include hubs, switches, routers, and gateways. Most large networks contain several levels of interconnection, the most important of which include edge connections, backbone connections, and widearea connections.

UDP (User Datagram Protocol) A communications method (protocol) that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP) and, together with IP, is sometimes referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet Protocol to actually get a data unit (called a datagram) from one computer to another. Unlike TCP, however, UDP does not provide the service of dividing a message into packets (datagrams) and reassembling it at the other end. Specifically, UDP doesnt provide sequencing of the packets that the data arrives in. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order. Network applications that want to save processing time because they have very small data units to exchange (and therefore very little message reassembling to do) may prefer UDP to TCP. Upgrade To replace existing software of firmware with a newer version. Upload To send a file transmitted over a network. In a communications session, upload means transmit, and download means receive. URL (Uniform Resource Locator) The address that defines the route to a file on the Web or any other Internet facility. URLs are typed into the browser to access Web pages, and URLs are embedded within the pages themselves to provide the hypertext links to other pages. VLAN (Virtual LAN) A logical association that allows users to communicate as if they were physically connected to a single LAN, independent of the actual physical configuration of the network. WAN (Wide-Area Network) - A communications network that covers a wide geographic area, such as a state or country. WEP (Wired Equivalent Privacy) A data privacy mechanism based on 64-bit and 128-bit shared key algorithms, as described in the IEEE802.11 standard. WINIPCFG - Configuration utility based on the Win32 API for querying, defining, and managing IP addresses within a network. A commonly used utility for configuring networks with static IP addresses. Workgroup - Two or more individuals that share files and databases.
