20 FAQ ** What kind of antenna should be used? The RF output of WizFi210 is processed through U.FL interface. Between the module and Antenna, there are U.FL connector, cable and SMA connector. There are various types of antennas. (WizFi210EVB: PCB type 2dBi antenna) U.FL Connector Case 1 Dipole Antenna + Case 2 2dBi PCB type + Coaxial Cable Case 3 1dBi Chip Antenna (Optional) (Over 1K Order Base)

21 FAQ (CON T) ** What is communication range of WizFi210? If using 3dBi Antenna, WizFi210 supports about ~190m communication range. However, obstacles or multi-pass environment can affect the communication, and change the range. The main factors of communication range are the GAIN(dBi) of antenna and Receive Sensitivity. The communication range between wireless devices depends on output power and GAIN of antenna. If the sum of output power and antenna gain is higher, the communication range is wider

22 FAQ (CON T) ** Which does WizFi210 different another WiFi module 1.WizFi210 more flexible and stable in field - All Serial to WiFi function base the Serial to Ethernet module (WIZ1XXSR etc) 2.WIZnet Supporting the different Configuration tool - Quick start guide and WIZSmartScript software program all test AT CMD. - WiFi AT CMD support 3.Optimized Software - Simple I/O Control customize Simple I/O Control UART Simple I/O Control Embedde MCU WizFi210 WizFi210 SENSE SENSE

23 FAQ (CON T) **What kind of OS is required? - WizFi210 is stand-alone typed module independent of existing application board. Therefore, WizFi210 can be applied to any system having any kind of OS or Non OS. ** Certification - May ~June. 2011: KCC / CE / FCC ** Battery test - Environment : Every 10min wake up and send 10bytes to server - 3.6V LITHIUM Battery : lasting for ~ 3 years
