Reference Design Peripheral MCU WIFI MODULE If the peripheral MCU uses power source of 5V,it needs to add a level switching circuit in the connection of the serial port and the related circuit. The module needs a large current about 300mA when transmitting data,please ensure that the power source can provide sufficient current. 13www.ibroadlink.com 8. AntennaCharacteristics 8.1 Antenna Selection The WT1SBSL supports on-board PCB printed antenna.When the Operating Frequencyis between 2.4G~2.5GHz, S11 of antenna port is less than-10dB and peak gainis about 1. 5dBi. Figure 7. Antenna radiation pattern simulation Figure 8. Antenna port S11simulation curve In practical use, 3328-P is welded on user’s boardand value of S11 has some changes. 14www.ibroadlink.com 8.2 Minimizing Radio Interference When integrating the Wi-Fi module with on board PCB printed antenna, make sure the three points below: 1. The area under the antenna end of the module should be keep clear of metallic components, connectors, vias, traces and other materials that can interfere with the radio signal. 2. The area around the antenna end the module protrudes at least 10mm from the mother board PCB and any metal enclosure. 3. When planning PCB layout, it is recommended that user places the antenna of Wi-Fi module as close as possible to the edge of boarder to ensure the good performance of antenna, which is shown in the picture below. 8.3 Specification of On-Board Antenna OperatingFrequency 2.4G~2.5GHz VSWR(max) Peak Gain 1.5dBi AntennaType PIFA 15www.ibroadlink.com Appendix A Glossary(Quentin respible) ADC AES ANT AP BPSK Analog-to -Digital Converter Advanced Encryption Standard Antenna Wireless Access Point Binary Phase Shift Keying CCK CDM Complementary Code Keying Charge Device Model DBPSK DC Differential binary phase shift keying Direct Current DHCP Dynamic Host Configuration Protocol CMOS Complementary Metal Oxide Semiconductor DNS DQPSK DSSS DTIM EMSP ESD EVM FCC FER GND GPIO HBM IEEE IO IOT IPv4 LED LVTTL MAC MCS MCU MIMO MSL NC NRST OFDM OSC PCB PIFA QPSK Determination of non-significance Differential quadrature phase shift keying Demand assigned signaling and switching subsystem Digital Transmission Interface Module Enhanced Modular Signal Processor Electrostatic Discharge Error Vector Magnitude Federal Communications Commission Floating Error Ground General Purpose Input/Output Human body model Institute of Electrical and Electrionics Engineers Input/Output Individual operation test Internet Protocol version 4 Light-emitting diode Low Voltage Transistor Transistor Logic Medium Access Control layer Modulation and coding scheme Microcontroller Unit Multiple-Input Multiple-Output Multilayer Switching Protocol Numerical Control Negative Reset Orthogonal Frequency Division Multiplexing Oscillator Printed Circuit Board Planar inverted F antenna Quadrature Phase Shift Keyin 16www.ibroadlink.com RC RF RISC RoHS RX SDIO SoC SPDT SPI STA TCP TKIP TX IP UART UDP UFL VSWR WEP WEPA WEP64 WEP128 WPA2 XTAL QAM 802.11 b/g/n Resistance- capacitance Radio Frequency Reduced Instruction Set Computer Restriction of Hazardous Substances Receiver Serial Digital Input/Output System on Chip Single-Pole Double-Throw Serial Peripheral Interface Spanning Tree Algorithm Transfer Control Protocol Temporal Key Integrity Protocol Transmitter Internet Protocol Universal Asynchronous Receiver/Transmitter User Datagram Protocol a miniature coaxial RF connector for high-frequency signals manufactured by Hirose Electric Group Voltage Standing Wave Ratio Wired Equivalent Privacy Welded Electronic Packaging Association 64 bit Wired Equivalent Privacy 128 bit Wired Equivalent Privacy Wi-Fi Protected Access 2 External Crystal Oscillator Quadrature Amplitude Modulation The IEEE 802.11 b/g/n 17www.ibroadlink.com Appendix B Reference paper(Quentin respible) [1] IEEE 802.11b/g/n- published IEEE 802.11-2007wireless networking standard and published IEEE 802.11-2012 standard for Information technology - Clause 19 of the publishedIEEE 802.11-2007 standard, and Clause 19 of the published IEEE 802.11-2012 standard.

If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. MPE Requirements To satisfy FCC / IC RF exposure requirements, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. Les antennes installées doivent être situées de facon à ce que la population ne puisse y être exposée à une distance de moin de 20 cm. Installer les antennes de facon à ce que le personnel ne puisse approcher à 20 cm ou moins de la position centrale de l’ antenne. La FCC des éltats-unis stipule que cet appareil doit être en tout temps éloigné d’au moins 20 cm des personnes pendant son functionnement.
