Airborne DP550 Family Databook B&B Electronics, Inc. 21 7.3 SPI Protocol A SPI message is composed of a 4 byte header followed by 0 or more bytes of data. The header data is full-duplex. That is, the TX message header is sent to the Airborne Device Server module by the host at the same time that the RX message header is sent to the host from the Airborne Device Server. The TX message header consists of a Command (CMD) byte, followed by three Parameter (PARM) bytes. They are described in the SPI Commands section 0 below. The RX message header is shifted out as the first four bytes of an SPI message regardless of the contents of the TX message header. The RX message header consists of a RX Data Available field and a TX Buffer Available field. The RX Data Available field indicates the number of data bytes the Device Server has available for the host. The data can be received by the RXDATA command. The TX Buffer Available field indicates how many data bytes the Device Server is able to accept from the host. This data is to be shifted in by the host using the TXDATA (Table 16) command. Both fields are 16 bit values and are stored in little-endian format (Least significant byte first).  The /SPI_SEL signal must be de-asserted between successive SPI messages. The messages will not be processed correctly if /SPI_SEL is held asserted across multiple messages. Table 13 - TX Message Header 0 1 2 3 CMD PARM1 PARM2 Table 14 - RX Message Header 0 1 2 3 RX Data Available TX Buffer Available  SPI data is transferred most significant bit first (msb).
B&B Electronics, Inc. Airborne WLNN DP550 Family Databook 22 7.4 SPI Modes The Airborne device supports the following four SPI modes. These are selectable through the command line or web interfaces. The default mode is zero (0). Table 15 - SPI Modes SPI Mode Clock Idle Clocking Edge 0 Low High-Low (trailing edge) 1 Low Low-High (leading edge) 2 High Low-High (trailing edge) 3 High High-Low (leading edge) 7.5 SPI Commands The following commands are available for use in the CMD message header.  Unused parameters should be set to zero. Table 16 - SPI Command Description Command (Hex) Name Description 0x00 NOP The NOP command does nothing. It is intended to be used when the host wants to simply retrieve the RX Message Header without any other operation. PARM1 and PARM2 are unused for this command and should be set to zero. 0x04 BREAK The BREAK command will issue a break sequence to the module. It is analogous to the BREAK signal on a common UART. Use this command to issue a BREAK if the esc-mode-serial brk setting is configured in the module. PARM1 and PARM2 are unused for this command and should be set to zero. 0x08 TXINTCLR The TXINTCLR command will clear the TX interrupt. Use this command when the module is issuing a TX interrupt but the host has no more data to send. This is analogous to the reset TX interrupt command on a common UART. The result of this command is that the TX interrupt is cleared even though the host is not writing more data to the module. PARM1 and PARM2 are unused for this command and should be set to zero.
Airborne DP550 Family Databook B&B Electronics, Inc. 23 Command (Hex) Name Description 0x10 INTENA The INTENA command will configure the specific interrupts to be enabled from the module. For this command, the PARM1 field will define the interrupts to be enabled. The definition of the PARM1 field for this command is a bit-mask and is formatted as follows: Bit 7 Interrupt Sense – Determines the asserted state of the interrupt pin. If this bit is set to a 1, the interrupt pin will be active high; otherwise the interrupt pin will be active low. The module will use the setting of this bit from the most recently issued INTENA command to determine the Interrupt Sense. Bit 1 TX Interrupt – If this bit is set to a 1, the interrupt pin will be asserted when there is space available in the TX buffer. The interrupt will be cleared when the module has TX data to process from the host. Alternately, the host can clear this interrupt by using the TXINTCLR command if the host has no more data to send. Bit 0 RX Interrupt – If this bit is set to a 1, the interrupt pin will be asserted when there is RX data available. The interrupt will be cleared when the host has received all the RX data available from the module. All other bits of PARM1 are unused for this command and should be set to zero. PARM2 is unused for this command and should be set to zero. For example, to enable TX interrupts with the interrupt pin active high, use the SPI message 0x10 0x82 0x00 0x00. That is, SPI command 0x10, PARM1 is 0x82, PARM2 is 0x0000. Important: The INTENA command can only be used to enable the specified interrupts. This command cannot be used to disable specified interrupts by setting the corresponding interrupt enable bits to zero in PARM1. The INTDIS command must be used to disable the specified interrupts. 0x20 INTDIS The INTDIS command will configure the specific interrupts to be disabled from the module. For this command, the PARM1 field will define the interrupts to be disabled. The definition of the PARM1 field for this command is a bit-mask and is formatted as follows: Bit 1 TX Interrupt – If this bit is set to a 1, The TX interrupt function will be disabled. Bit 0 RX Interrupt – If this bit is set to a 1, the RX interrupt function will be disabled. All other bits of PARM1 are unused for this command and should be set to zero. PARM2 is unused for this command and should be set to zero. For example, to disable TX interrupts, use the SPI message 0x20 0x02 0x00 0x00. That is, SPI command 0x20, PARM1 is 0x02, PARM2 is 0x0000.
B&B Electronics, Inc. Airborne WLNN DP550 Family Databook 24 Command (Hex) Name Description 0x40 TXDATA The TXDATA command is used to send data to the module to be interpreted as commands if the module is in CLI mode, or to be transmitted on the wireless link if the module has an active data connection established. The host may send at most the number of bytes indicated by the TX Buffer Available field in the RX Message Header. The actual number of bytes sent by the host is determined by the 16 bit value in PARM2. The value in PARM2 is little-endian (least significant byte first) and must be less than or equal to the number in the TX Buffer Available field. Any bytes sent in excess of this number will be ignored. PARM1 is unused for this command and should be set to zero. For example, to send the auth dpac dpac command, use the SPI message 0x40 0x00 0x0F 0x00 0x61 0x75 0x74 0x68 0x20 0x64 0x70 0x61 0x63 0x20 0x64 0x70 0x61 0x63 0x0D. That is, SPI command 0x40, PARM1 is 0x00, PARM2 is 0x000F, followed by the text for auth dpac dpac. 0x80 RXDATA The RXDATA command is used to receive data from the module. In CLI mode, this data will be the local echoing of the commands issued to the module, as well as the command responses generated by the module. If the module has an active data connection established, this data will be the data received on the wireless link. The host may receive at most the number of bytes indicated by the RX Data Available field in the RX Message Header. The actual number of bytes received by the host is determined by the 16 bit value in PARM2. The value in PARM2 is little-endian (least significant byte first) and must be less than or equal to the number in the RX Data Available field. If additional clock cycles are sent to the module beyond this number, meaningless data will be returned. PARM1 is unused for this command and should be set to zero. The TXDATA and RXDATA commands can be combined for full-duplex operation. For example, a command byte of 0xC0 would be a TXDATA and RXDATA command combined. The result of this command would be that the module would accept data being shifted in as TX data, while at the same time, RX data would be shifted out. In this case, the number of bytes transferred for TXDATA must be equal to the number of bytes transferred for RXDATA. The PARM2 parameter will indicate the number of bytes to be transferred for both the TXDATA and RXDATA commands.
Airborne DP550 Family Databook B&B Electronics, Inc. 25 8.0 Antenna The unit supports antenna connections through two Hirose U.FL connectors (ANT1 and ANT2). They are located on the top surface of the device next to the RF shielding. Antenna selection options are selectable through both the web and command line interfaces. Any antenna used with the system must be designed for operation within: the 2.4GHz ISM band and must specifically support 2.412GHz to 2.482GHz for 802.11b/g, the 5GHz ISM band and must specifically support 5.1GHz to 5.9GHz for 802.11a operation. They are required to have a VSWR of 2:1 maximum referenced to a 50Ω system impedance. 8.1 Antenna Selection The Airborne radio supports a number of antenna options, all of which require connection to the U.FL connectors on the radio. The best antenna option will be determined by a number of factors. These include the application, mechanical construction and desired performance. Since the number of possible combinations is enormous, we will review some of the more common solutions in this section. Contact Technical Support for more specific answers if your application is not covered during this discussion. The available antenna connections include: Host board mounted antenna Host chassis mounted antenna Embedded antenna Location and performance also need to be considered. The following sections discuss these factors. 8.2 Host Board Mounted Antenna Host board mounting requires that an antenna connection be physically mounted to the host system board. It also requires that the host board include a U.FL connector to allow a U.FL to U.FL coaxial lead to connect from the radio to the host board. It will then require 50Ω matched PCB traces to be routed from the U.FL connector to the antenna mount. There are several sources for the U.FL to U.FL coaxial cable. These include Hirose, Sunridge and IPEX. Please contact B&B for further part numbers and supply assistance. This approach can simplify assembly, but it does require that the host system configuration can accommodate an antenna location that is determined by the host PCB. This approach also makes it harder to seal the enclosure. Host board mounting also limits your choices of antenna. You must use antennas that screw or press fit to the PCB mount connector. There are many antenna connector types, but if you wish to utilize the FCC/IOC modular approval the connector choice must comply with FCC regulations. These state that a non-standard connector is required. For example, RP-TNC/RP-SMA are allowed, and TNC/SMA are not.
B&B Electronics, Inc. Airborne WLNN DP550 Family Databook 26 8.3 Host Chassis Mounted Antenna Host Chassis mounted antennas require no work on the host PCB. They use an antenna type called ‘flying lead’. There are two types of flying leads. One provides a bulkhead mounted antenna connector and the other provides a bulk head mounted antenna. The type you choose will be determined by the application. A flying lead system connects a U.FL coaxial lead to the radio’s U.FL connector. The other end of the coax is attached to either a bulkhead mounted antenna connector or directly to an antenna that has an integrated bulkhead mount. In either case, the use of host chassis mounting significantly reduces the antenna system development effort. It provides for greater flexibility in antenna choice and placement in the host system chassis. When using the flying lead antenna (integrated bulk head mounting) there are no connector choice restrictions for use with the FCC/IOC modular certification. However if the flying lead connector is used, the same restrictions as identified for the Host Mounted Antenna apply. There are many suppliers of flying lead antenna and connectors. B&B’s Airborne Antenna product line offers a range of antenna solutions. 8.4 Embedded Antenna Embedded antennas can be the most interesting approach for M2M, industrial and medical applications. Their small form factor and the absence of any external mounting can make them very useful. But they will typically provide lower performance than an external antenna. This does not make them unusable, but it will impact the choice of antenna type and it will require more focus on antenna placement. The three main embedded antenna types are PCB embedded, chip (PCB mounted) and flying lead. Each has its advantages and disadvantages (See Table 17). Table 17 - Embedded Antenna Options Antenna Type Features Cost Size Availability Performance PCB Embedded Lowest Largest Custom Poor Chip Low Small Standard Poor Flying Lead Low Small Standard Fair PCB Embedded – This approach embeds an antenna design into the host PCB. It is very common with add-in Wi-Fi cards (CF, PCMCIA, SDIO, etc.), as it requires no external connections and has the lowest production cost. But the lower production costs are offset by significant development costs and diminished performance and flexibility. Chip – The integration of a chip antenna is simple, and it requires a relatively small footprint on the host system. But, like a PCB embedded antenna, there will be limitations in flexibility and performance.
Airborne DP550 Family Databook B&B Electronics, Inc. 27 Many suppliers can provide chip antennas; many configuration and performance options are available. Flying Lead – Embedded flying lead antennas are similar to external flying lead antennas. The difference is that the embedded antennas have smaller form factors and provide a range of chassis and board mounting options. Embedded flying lead antennas tend to provide more performance and flexibility than other approaches, since the location of the antenna is not determined by the host PCB design. The assembly of a system using embedded flying lead antennas may be slightly more complex, as the antenna is not necessarily mounted on the host PCBA. 8.5 Antenna Location The importance of location cannot be over stressed. It can often be the difference between the success and failure of a Wi-Fi implementation. There are several factors that need to be considered when determining location:  Distance of Antenna from radio.  Location of host system. − Proximity to RF blocking or absorbing materials. − Proximity to potential noise or interference. − Position relative to infrastructure (Access Points or Laptops).  Orientation of host system relative to infrastructure. − Is it known? − Is it static? The following things need to be considered during the development process: 1. Minimize the distance between the radio and the location of the antenna. The coaxial cable between the two impacts the Transmit Power and Receive Sensitivity negatively. B&B recommends using 1.32-1.37mm outer diameter U.FL coaxial cables. 2. Minimize the locations where metal surfaces come into contact or are close to the location of the antenna. 3. Avoid locations where RF noise may occur, whether it is close to or overlapping the ISM bands. This would include microwave ovens and wireless telephone systems in the 2.4GHz frequency range. 4. Mount the antenna as high on the equipment as possible. 5. Locate the antenna where there is a minimum of obstruction between the antenna and the location of the Access Points. Access Points are typically located in the ceiling or high on walls. 6. Keep the main antenna’s polarization vertical, or in-line with the antenna of the Access Points. 802.11 systems use vertical polarization and aligning both transmit and receive antenna maximizes the link quality. All of these factors will influence connection quality. 8.6 Performance Performance is difficult to define. The appropriate metric changes with each application, and may be a combination of parameters and application requirements. The most important characteristic will normally be link quality. This
B&B Electronics, Inc. Airborne WLNN DP550 Family Databook 28 can be defined as the available bandwidth between the two devices. The lower the link quality, the less likely it will be that the devices can communicate. Measurement of link quality can be made in several ways; Bit Error Rate (BER), Signal to Noise (SNR) ratio, Signal Strength and distortion. The link quality is used by the radio to determine the link rate. In general, when the link quality for a given link rate drops below a predefined limit the radio will drop to the next lowest link rate and try to communicate at that rate. The reverse is also true. If the radio observes good link quality at one rate it will try to move up to the next rate to see if communication can still be sustained. Note that for a given position the link quality improves as the link rate is reduced. As the link rate drops, the radios’ Transmit power and Receive sensitivity improve. Looking at the link rate is an indirect way of assessing the quality of the link between the device and an Access Point. You should strive to make the communication quality as good as possible in order to support the best link rate. But be careful not to over specify the link rate. Consider your application’s bandwidth requirements and tailor your link rate to optimize the link quality. For example, if the link quality for a location at 6Mb/s is better than it would be for 54Mb/s, and the application only needs 2Mb/s of data throughput, the 6Mb/s rate would provide better link quality. Radio performance is only one of the things that contribute to the link quality. Other factors include the items discussed earlier and choices made regarding overall antenna gain. The antenna gain contributes to the Equivalent Isotropically Radiated Power (EIRP) of the system. This is called link margin, and it is part of the overall measurement of the link quality. Link Margin provides a measure of all the parts of the RF path that impact the communications between two systems. The basic equation looks like this: EIRP (dB) = TxP + TxA – TxC Link Margin (dB) = EIRP – FPL + (RxS + RxA – RxC) Where: TxP = Transmitter output power (dBm) TxA = Transmitter antenna gain (dBi) TxC = Transmitter to Antenna coax cable loss (dB) FPL = Free Path Loss (dB) RxS = Receiver receive sensitivity (dBm) RxA = Receiver antenna gain (dBi) RxC = Receiver to Antenna coax cable loss (dB) This is a complex subject and we won’t try to cover it here. B&B’s technical experts can help you if you need to explore it in more detail. But you should understand that optimizing link quality involves a combination of hardware selection, design choices and radio configuration.

Airborne DP550 Family Databook B&B Electronics, Inc. 35 Table 20 - Modular Grant Numbers Country Standard Grant North America (US) FCC Part 15 Sec. 15.107, 15.109, 15.207, 15.209, 15.247 Modular Approval F4AWLNN551 Canada RSS 210 Modular Approval 3913A-WLNN551 By providing FCC modular approval on the Airborne WLN modules, the customers are relieved of any need to perform FCC part15 subpart C Intentional Radiator testing and certification, except where they wish to use an antenna that is not already certified. B&B supports a group of pre-approved antenna; use of one of these antennas eliminates the need to do any further subpart C testing or certification. If an antenna is not on the list, it is a simple process to add it to the pre-approved list without having to complete a full set of emissions testing. Please contact B&B Technical support for details of our qualification processes. Please note that as part of the FCC requirements for the use of the modular approval, the installation of any antenna must require a professional installer. This is to prevent any non-authorized antenna being used with the radio. There are ways to support this requirement but the most popular is to utilize a non-standard antenna connector, this designation includes the reverse polarity versions of the most popular RF antenna types (SMA, TNC, etc.). For more details please contact B&B. The following documents are associated with this applications note: FCC Part 15 – Radio Frequency Devices FCC Public Notice – DA 00-1407 (June 26th, 2000) B&B recommends that during the integration of the radio, into the customers system, that any design guidelines be followed.
