The module is a single circuit card packaged in a PCI Express Mini Card form factor, and supports all the RF, analog, and digital circuitry necessary to implement WLAN functionality. Using Digi’s baseband processor technology, this module is the ideal choice for embedded applications requiring long-term product availability in conjunction with reliability and easy design integration. The primary interface to the module is through a standards-compliant PCI Express Mini Card edge connector, using a USB 2.0 full speed/…

The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with FCC Part 15 and Industry Canada limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The Digi Connect Wi-Wave 802.11 b/g module is designed such that all RF components and circuitry are placed on the top surface of the PCB. No RF related circuitry is present on the bottom surface of the PCB. A formed metal shield is soldered onto the top of the PCB and covers all RF components and circuitry. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 and Industry Canada requirements under conditions of excessive data rates or over-modulation. All of the user data that is to be transmitted over the modular transmitter is buffered by the Digi Connect Wi-Wave 802.11 b/g baseband controller. The user’s data is packetized and transmitted at data rates that are completely controlled by the baseband controller and its software. The user has no access to either the baseband controller or its software. 3. The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 and Industry Canada requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. All critical RF circuitry runs on a locally regulated power supply which allows the module to function within specification with worst case input voltages ranging from 3.1V (module will enter a non-operative state if the Vin drops to <3V ) to 3.6V (Vin >3.6V will cause a catastrophic failure of the processor and the unit will cease to function). The optimal Vin voltage range is 3.3V +/-9%. Digi International 11001 Bren Road East Minnetonka, MN 55343 952-912-3444 tel 952-912-4991 central fax 4. The modular transmitter must comply with the antenna requirements of FCC Sections 15.203 and 15.204(c) and Industry Canada requirements. The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). Any antenna used with the module must be approved with the module, either at the time of initial authorization or through a Class II permissive change. The “professional installation” provision of FCC Section 15.203 may not be applied to modules. The Digi Connect Wi-Wave 802.11 b/g module has one antenna configuration: usage of two U.FL antenna connectors. Transmission is made only on one antenna – the second one is foreseen for receive diversity. The antennas specified for the Digi Connect Wi-Wave 802.11 b/g module is: • ANT-DB1-RAF-RPS 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with FCC Part 15 and Industry Canada emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in FCC Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see FCC Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see FCC Section 15.31(i)). The Digi Connect Wi-Wave 802.11 b/g module is designed to be compliant with all relevant FCC requirements without any additional shielding or filtering of any sort. As tested, the Digi Connect Wi- Wave 802.11 b/g module was mounted on top of a carrier board which provided the +3.3VDC to power the module and an USB line transceiver to allow serial data traffic. The carrier board drives the +3.3V from an on-card DC to DC converter which is in turn powered by an external +12VDC power supply which is mains powered. There are no additional filters associated with the module/carrier board. Nor is there any additional shielding associated with this setup – beyond the shield that is soldered to the module. Digi International 11001 Bren Road East Minnetonka, MN 55343 952-912-3444 tel 952-912-4991 central fax 6. The modular transmitter must be labeled with its own FCC ID / IC number, and, if the FCC ID / IC number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1 / IC: XXX-YYYY” or “Contains FCC ID: XYZMODEL1 / IC: XXX-YYYY.” Any similar wording that expresses the same meaning may be used. The Applicant may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions…

S = PG/4R 2 where S = power density ( in appropriate units, e.g. mW/cm 2 ) P = power input to the antenna (in appropriate units e.g. mW) G = power gain of the antenna in the direction of interest relative to the isotropic radiator R = distance to the centre of radiation of the antenna (appropriate units e.g. cm) Or S = EIRP/4R 2 where EIRP = equivalent isotropically radiated power Calculation: (Calculated for max. EIRP) EIRP: 24.98 dBm (314.8 mW) calculated at distance of 20 cm: power density = 314.8 /420 2 = 0.06266 mW/ cm 2 Limit: 1mW/ cm 2 is the reference level for general public exposure according to the OET Bulletin 65, Edition 97-01 Table 1.
