SWL-2900U is the USB 2.0 module that adopts a single-chip wireless local area network (WLAN) medium-access controller (MAC) spread-spectrum baseband processor and 2.4 GHz RF radio. SWL-2900U supports IEEE 802.11b, and 802.11g standards. Data rates up to 54 Mbps can be provided in 802.11g mode of operation. The main IC of SWL-2900U includes an 80MHz ARM7 core, 384 KB of on-chip SRAM, and 80 KB of onchip ROM. SWL-2900U is able to host the entire WLAN driver and TCP/IP stack on-chip. This minimizes development time, cost, and burden on the host processor resources making SWL-2900U an ideal WLAN solution for nomadic application. SWL-2900U provides crucial power management functionality and requires only a single 5.0 V supply voltage.

REV 0.9 Samsung Electro-Mechanics Proprietary 12/12 Regulatory Information FCC Compliance Ì FCC Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Ì Caution Any changes or modifications NOT explicitly APPROVED by Samsung Electronics Co., Ltd. could cause the SWL-2900U module to cease to comply with FCC rules part 15, and thus void the user's authority to operate the equipment. Ì RF-exposure statement These modular transmitters, SWL-2900U, comply with FCC radiation exposure limits set forth for an uncontrolled environment. The SWL-2900U should be installed and operated with minimum distance 20cm between the antenna and the body of the user or nearby persons. The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrate this module. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as the 2 conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. Ì Antenna These modular transmitters are for OEM integrations only. The end-user product will be installed in such a manner that only the authorized antennas are used. Ì Label and manual requirements for the End Product For an end product using the SWL-2900U there must be a label containing, at least, the following information: FCC ID for model SWL-2900U This device contains FCC ID: A3LSWL-2900U The label must be affixed on an exterior surface of the end product such that it will be visible upon inspection in compliance with the modular approval guidelines developed by the FCC. Where the SWL-2900U will be installed in final products larger than 8cm x 10cm following statements has to be placed ONTO the device. "This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation." In case where the final product will be installed in locations where the end-consumer is not able to see the FCC ID and/or this statement, the FCC ID and the statement shall also be included in the end-product manual. The users manual for end users must include the following information in a prominent location "IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter." EU Compliance Ì Regulatory compliance of the SWL-2900U The SWL-2900U are made for OEM integrations only. The European regulations applying to the SWL-2900U is the R&TTE Directive 1999/5/EC. SWL-2900U meets the following requirements of the R&TTE Directive. R&TTE Directive Test category article Harmonized standard Article 3.1(a) Protection of health and safety EN 60950-1, EN 50385 Article 3.1(b) EMC EN 301 489-1/-17 Article 3.2 Effective use of the spectrum EN 300 328 The conformity assessment for the SWL-2900U were completed in accordance with the R&TTE Directive Annex IV procedures, and the EC Declaration of Conformity is attached to this manual. Ì Cautions regarding regulatory compliance when integrating the SWL-2900U The person integrating the SWL-2900U becomes the manufacturer of the final product and is therefore responsible for demonstrating compliance of the product with the essential requirements of the R&TTE Directive. In all cases assessment of the final product must be made against the Essential requirements of the R&TTE Directive Article 3.1(a) and (b), safety and EMC respectively, and any relevant Article 3.3 requirements This device is intended only for OEM integrators under the following conditions: 1. This appliance and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter. 2. A minimum separation distance of 20 cm must be maintained between the antenna and the person for this appliance to satisfy the RF exposure requirements of the Council recommendation 1999/519/EC of 12 July 1999. As long as the 2 conditions above are met, no further evaluation under Article 3.2 of the R&TTE Directive and do not require further involvement of an R&TTE Directive Notified Body for the final product. In all other cases, or if the manufacturer of the final product is in doubt then the equipment integrating the radio module must be assessed against Article 3.2 of the R&TTE Directive. Please note that this product, SWL-2900U, uses radio frequency bands not harmonized throughout the Community. This product is classified as Class 2 radio equipment for which some Member States apply restrictions on placing on the market and in use. Any parties putting Class 2 radio equipment on the market must notify the relevant national spectrum management authority of their intention, and the radio equipment must be given a Class Identifier (alert symbol). Ì Antenna This product, SWL-2900U, is for OEM integrations only. The end-user product will be installed in such a manner that only the authorized antennas are used. Ì Enclosure This product, SWL-2900U, is made for integrating in another final product. For this reason, there are some parts of the final product on which the SWL-2900U depends for regulatory compliance regarding EMC and safety. The SWL-2900U is mounted on the circuit board of the final product, and must be contained inside the case of the final product. Integrated the SWL-2900U in the final product so that its surfaces are not in contact with the outside. Ì Documentation In the documentation for the conformity assessment of the final product, state clearly that the SWL-2900U is integrated in the system. Ì Conformity Assessment of the Products integrating the SWL-2900U The following is a supplementary explanation of conformity assessments for final products integrating the radio modules such as the SWL-2900U, that have passed conformity assessments in accordance with the R&TTE Directive. The procedures for conformity assessment in accordance with the R&TTE Directive are the responsibility of the manufacturer of the final product. With final products integrating radio modules, the person who integrates the module in the system becomes the manufacturer of the final product, and it is their responsibility to certify that the requirements of the R&TTE Directive and met. Ì Exemption from conformity assessment However, if radio modules that meet the requirements of the R&TTE Directive and that have passed the conformity assessment are integrated in a final product that follows the cautions concerning integrating radio modules, they are exempted from the conformity assessment for R&TTE Directive Article 3.2 (efficient use of the radio spectrum). For details, refer to the following Guidance and ETSI Technical Report from the R&TTE Compliance Association, and check whether your case applies.
