Page 1 Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 1.1 OVERVIEW Airborne™ is a line of highly integrated 802.11b/g modules. The Airborne™ Radio Module delivers a highly integrated solution for consumer and industrial wireless applications using the industry-standard IEEE 802.11b/g platform. It delivers both a cost and space efficient solution using a small profile design and direct down SMT high density header (Zero-IF) connection to the system board. The two-chip design significantly reduces product cost and form factor. It is a complete high-speed wireless solution that uses the latest 802.11b/g chipset from Marvell which is backward compatible with the 802.11b DSSS standard and adds the new 802.11g OFDM (orthogonal Frequency Division Multiplexing) standard support. This chip set includes integrated antenna connectors that provide a direct connection from the radio to the antenna. This bypasses the system board, which simplifies the integrator’s board design. The radio is a true upgrade option because no soldered connections are required. It can be upgraded in the field or added to a managed product configuration. 1.2 CONFIGURATIONS The Airborne™ Radio Module consists of an 802.11b/g radio transceiver and Media Access Controller (MAC) with a Compact Flash (CF) interface.

NoteNote The interface is a subset of a PC Card interface. 2.3.3 Pin Features* The following describes specific features of various pins:
Page 11 Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 Table 9 - Pin Definition and Descriptions Pin feature Description A[9:0] Decoding of the system address space is performed by the CEx-. During I/O accesses A[5:0] decode the register. A[9:6] are ignored when the internal HAMASK register is set to the defaults used by the standard firmware. During attribute memory accesses A[9:1] are used. D[15:0] The host interface is primarily designed for word accesses, although all byte access modes are fully supported. See CE1-, CE2- for a further description. Note that attribute memory is specified for and operates with even bytes accesses only. CE1-, CE2- The PC Card cycle type and width are controlled with the CE signals. Word and Byte wide accesses are supported, using the combinations of HCE1-, HCE2-, and HA0 as specified in the PC Card standard. WE-, OE HOE and HWE- are only used to access attribute memory. Common Memory, as specified in the PC Card standard, is not used in the MODULE. HOE- is the strobe that enables an attribute memory read cycle. HWE- is the corresponding strobe for the attribute memory write cycle. The attribute space contains the Card Information Structure (CIS) as well as the Function Configuration Registers (FCR). IORD-, IOWR IORD-and HIOWR- are the enabling strobes for register access cycles to the MODULE. These cycles can only be performed once the initialization procedure is complete and the MODULE has been put into IO mode. REG This signal must be asserted for I/O or attribute cycles. A cycle where HREG- is not asserted will be ignored as the MODULE does not support common memory. INPACK This signal is asserted by the MODULE whenever a valid I/O read cycle takes place. A valid cycle is when HCE1-, HCE2-,- HREG-, and HIORD- are asserted, once the initialization procedure is complete.
Page 12 Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 Pin feature Description WAIT Wait states are inserted in accesses using HWAIT-. The host interface synchronizes all PC Card cycles to the internal MODULE clock. The following wait states should be expected: Direct Read or Write to Hardware Register • 1/2 to 1 MCLK assertion of HWAIT- for internal synchronization. Write to Memory Mapped Register, Buffer Access Path, or Attribute Space (Post-Write) • The data required for the write cycle will be latched and therefore only the synchronizing wait state will occur. • Until the queued cycle has actually written to the memory, any subsequent access by the Host will result in a WAIT. Read to Attribute Space and Memory Mapped Registers • WAIT will assert until the memory arbitration and access have completed. Buffer Access Paths, BAP0 and BAP1 • An internal Pre-Read cycle to memory is initiated by a host Buffer Read cycle, after the internal address pointer has auto-incremented. If the next host cycle is a read to the same buffer, the data will be available without a memory arbitration delay. • A single register holds the pre-read data. Thus, any read access to any other memory-mapped register (or the other buffer access path) would result in the pre-read data becoming invalidated. • If another read cycle has invalidated the pre-read, then a memory arbitration delay will occur on the next buffer access path read cycle. IREQ Immediately after reset, the HIREQ- signal serves as the RDY/BSY (per the PC Card standard). Once the MODULE firmware initialization procedure is complete, HIREQ- is configured to operate as the interrupt to the PC Card socket controller. Both Level Mode and Pulse Mode interrupts are supported. By default, Level mode interrupts are used, so the interrupt source must be specifically acknowledged or disabled before the interrupt will be removed. Register Interface The logical view of the MODULE from the host is a block of 32-word wide registers. These appear in IO space starting at the base address determined by the socket controller. Hardware Registers (HW) • 1 to 1 correspondence between addresses and registers. • No memory arbitration delay, data transfer directly to/from registers. • AUX base and offset are write-only, to set up access through AUX data port. NoteNote All register cycles, including hardware registers, incur a short wait state on the PC Card bus to insure the host cycle is synchronized with the MODULE's internal MCLK.

Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 3.1 DESIGN GUIDELINES The Module can be implemented into various solutions. Any design must meet the following guidelines:  Provide 3.3 V to all Vdd power pins.  Provide ground connections to all Vss pins.  Provide a connection to a suitable antenna. Caution!Caution! The 3.3 V power supply should be a low-noise design, with less than 150 mV ripple at the maximum average transmit current. The power supply should also be designed to provide sufficient power to handle the Module’s power-up inrush current. 3.2 EMI/RFI GUIDELINES To minimize electromagnetic interference (EMI) and radio frequency interference (RFI), pay strict attention to power and signal routing near the Module. As much as possible, the keep-clear area below the Module should be a solid copper ground plane. It is anticipated that the Module will be mounted on a board with a committed ground plane. Ensure the inter-connect has a designed impedance of 50-75 Ohms. To keep signal impedance as low as possible, connect the ground plane to internal ground planes by several vias. Ground signals to the Module connector should connect directly to the ground plane below the Module. Individual ground connections to the Module should have a solid ground connection, preferably directly to the ground plane on the same surface side where the Module resides. Do not connect ground pins directly to an inside layer ground plane using vias. Keep interconnects from the Module connector as short as possible on the mounting layer. All inboard signals–including pin numbers–must immediately transition to a different routing layer using a via as close to the connector as possible. Outboard signals (odd pin numbers) should also be kept to a minimum length. 3.3 CIRCUIT BOARD LAYOUT PRACTICES When considering capacitance, calculations must consider all device loads and capacitances due to printed circuit board traces. Capacitance due to the traces depend on a number of factors, including the trace width, dielectric material from which the circuit board is made, and proximity to ground and power planes.

Guidelines for Mounting the Radio Module 3.4 MOUNTING GUIDELINES Special care must be observed when placing the Module. In particular:  The antenna must not be mounted beneath any other printed circuit boards, components, or metallic housing.  The proximity of the antenna to large metallic objects can affect the range and performance of the Module.  Packaging and enclosure designers must carefully review the placement of the Module in the enclosure to minimize interference or blocking sources. For mechanical clearance, performance, and emissions reasons, there should be no components placed on the main printed circuit board facing the Module. This region should be clear of components.

Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 A.1. USING RADIO FREQUENCIES IEEE 802.11 devices such as the Airborne™ Radio Module use radio-frequency signals in the Industrial, Scientific, and Medical (ISM) band between 2.4 GHz and 2.5 GHz to communicate with each other. Due to spread spectrum effect of the signals, a radio sending signals on a particular channel uses the frequency spectrum 12.5 MHz above and below the center channel frequency. As a result, two separate WLANs in the same general vicinity that use neighboring channels (channel 1 and channel 2, for instance) can interfere with each other. Applying two channels that allow the maximum channel separation decreases the amount of channel cross-talk and provides performance gains over networks with minimal channel separation. The preferred channel separation between the channels in neighboring wireless networks is 25 MHz (5 channels). Neighboring channels are 5 MHz apart. To minimize adjacent channel interference, you can apply a maximum of three different channels within your WLAN. There are 11 usable wireless channels in the United States. It is recommended that you start using channel 1 and grow to use channel 6, and 11 when necessary, as these three channels do not overlap. The following chart lists the 802.11 radio-frequency channels that are used. Table 11.

Page 19 Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 A.2. AUTHORIZED FREQUENCY CHANNELS BY REGION International wireless frequency standards are a result of an IEEE 802.11WLAN committee agreement. These standards enable the wireless data communication industry to develop interoperable, low-cost, integrated equipment such as the Airborne™ Radio Module. Authorized frequency channels vary by geographic region. The United States, Canada, Japan, Spain, France, and the ETSI, or remaining European countries, each have their own authorized frequencies. The following table illustrates authorized channels of operation according to geographic region. Though this list is believed to be accurate at time of publication, consult local regulatory authorities before using these channels of operation. Table 12.

You must use region-compliant firmware that restricts channel access, such as ETSI-compliant firmware. Because the end user does not have the ability to alter this firmware, regulatory compliance is ensured.
Page 20 Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 This appendix provides a glossary of wireless terminology. 802.11 Wireless standards developed by the IEEE that specify an "over-the-air" interface for wireless Local Area Networks. 802.11 is composed of several standards operating in different radio frequencies. 802.11a 802.11a is an IEEE specification for wireless networking that operates in the 5 GHz frequency range (5.725 GHz to 5.850 GHz) with a maximum 54 Mbps data transfer rate. The 5 GHz frequency band is not as crowded as the 2.4 GHz frequency, because the 802.11a specification offers more radio channels than the 802.11b/g. These additional channels can help avoid radio and microwave interference. 802.11b 802.11b is the international standard for wireless networking that operates in the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a throughput of up to 11 Mbps. 802.11g 802.11g is similar to 802.11b, but this forthcoming standard provides a throughput of up to 54 Mbps. It also operates in the 2.4 GHz frequency band but uses OFDM radio technology in order to boost overall bandwidth. Access Point An interface between a wireless network and a wired network Access Points can combine with a distribution system such as Ethernet to create multiple radio cells (BSSs) that enable roaming throughout a facility. Ad-Hoc mode A wireless network composed of only stations and no Access Point. Association service An IEEE 802.11 service that an enables the mapping of a wireless station to the distribution system via an Access Point. Asynchronous transmission Type of synchronization where there is no defined time relationship between transmission of frames. Authentication The process a station uses to announce its identify to another station. IEEE 802.11 specifies two forms of authentication: open system and shared key. Bandwidth The amount of transmission capacity available on a network at any point in time. Available bandwidth depends on several variables such as the rate of data transmission speed between networked devices, network overhead, number of users, and the type of device used to connect PCs to a network. Basic Service Set (BSS) A set of 802.11-compliant stations that operate as a connected wireless network. APPENDIX B: GLOSSARY
Page 21 Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 Bits per second (bps) A measurement of data transmission speed over communication lines based on the number of bits that can be sent or received per second. BSSID Basic Service Set Identifier. A 48-bit identifier used by all stations in a BSS in frame headers. Usually MAC address. Clear channel assessment A function that determines the state of the wireless medium in an IEEE 802.11 network. Client Any computer connected to a network that requests services (files, print capability) from another member of the network. Command Line Interface (CLI) A method of interacting with the Airborne WLN Module by sending it typed commands. Direct sequence spread spectrum (DSSS) Combines a data signal at the sending station with a higher data rate bit sequence, which many refer to as a chip sequence (also known as processing gain). A high processing gain increases the signal’s resistance to interference. The minimum processing gain that the FCC allows is 10, and most products operate under 20. Disassociation service An IEEE 802.11 term that defines the process a station or Access Point uses to notify that it is terminating an existing association. Distribution service An IEEE 802.11 station uses the distribution service to send MAC frames across a distribution system. GPIO General Purpose Input/Output refers to the digital I/O lines. Host application The environment within which the Module is embedded - typically includes a processor, which forms part of an OEM’s product and application. Hot spot Same as an Access Point, usually found in public areas such as coffee shops and airports. IEEE Institute of Electrical and Electronic Engineers, an international organization that develops standards for electrical . The organization uses a series of numbers, like the Dewey Decimal system in libraries, to differentiate between the various technology families. Independent Basic Service Set Network (IBSS Network) An IEEE 802.11-based wireless network that has no backbone infrastructure and consists of at least two wireless stations. This type of network is often referred to as an Ad-Hoc network because it can be constructed quickly without too much planning.
Page 22 Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 Infrastructure mode A client setting providing connectivity to an Access Point. As compared to Ad-Hoc mode, whereby PCs communicate directly with each other, clients set in Infrastructure mode all pass data through a central Access Point. The Access Point not only mediates wireless network traffic in the immediate neighborhood, but also provides communication with the wired network. See Ad-Hoc and AP. LAN application A software application that runs on a computer, which is attached to a LAN, Intranet or the Internet, and using various protocols can communicate with the Module. Local Area Network A system of connecting PCs and other devices within the same physical proximity for sharing resources such as Internet connections, printers, files and drives. When Wi-Fi is used to connect the devices, the system is known as a wireless LAN or WLAN. Medium Access Control Layer One of two sub-layers that make up the Data Link Layer of the OSI reference model. The MAC layer is responsible for moving data packets to and from one network node to another across a shared channel. MPDU MAC Protocol Data Unit, the unit of data exchanged between two peer MAC entities using the services of the physical layer (PHY). MSDU MAC Service Data Unit, information that is delivered as a unit between MAC service Access Points (SAPs). Peer-to-peer network A wireless or wired computer network that has no server or central hub or router. All the networked PCs are equally able to act as a network server or client, and each client computer can talk to all the other wireless computers without having to go through an Access Point or hub. However, since there is no central base station to monitor traffic or provide Internet access, the various signals can collide with each other, reducing overall performance. RS-232 An EIA standard that specifies up to 20 Kbps, 50 foot, serial transmission between computers and peripheral devices. RTOS An operating system implementing components and services that explicitly offer deterministic responses, and therefore allow the creation of real-time systems. An RTOS is characterized by the richness of the services it provides, the performance characteristics of those services, and the degree that those performance characteristics can be controlled by the application engineer ( to satisfy the requirements of the application).
Page 23 Airborne™ Wireless LAN Radio Module Data Book TBD QUATECH Confidential Rev. A 6/12/2006 Service Set Identifier (SSID) An identifier attached to packets sent over the wireless LAN that functions as a "password" for joining a particular radio network (BSS). All radios and Access Points within the same BSS must use the same SSID, or their packets will be ignored. Telnet A virtual terminal protocol used in the Internet, enabling users to log into a remote host. Transceiver A device for transmitting and receiving packets between the computer and the medium. Transmission Control Protocol (TCP) A commonly used protocol for establishing and maintaining communications between applications on different computers. TCP provides full-duplex, acknowledged, and flow-controlled service to upper-layer protocols and applications. Wide Area Network (WAN) A communication system of connected PCs and other computing devices across a large local, regional, national or international geographic area. Also used to distinguish between phone-based data networks and Wi-Fi. Phone networks are considered WANs and Wi-Fi networks are considered wireless LANs. Wi-Fi Wirekless-Fidelity: Wi-Fi is the common name used for 802.11 wireless network technology. Wi-Fi Alliance A non-profit international association formed in 1999 to certify interoperability of wireless LAN products based on IEEE 802.11 specification. Wired Equivalent Privacy (WEP) A security protocol for wireless LANs defined in the IEEE 802.11 standard. WEP is designed to provide the same level of security as a wired LAN. WLAN Also referred to as a wireless LAN. A type of local-area network that uses high-frequency radio waves rather than wires to communicate between nodes and provide network connectivity.
