Abstract: Wi-Fi (2 401 ~ 2 483 MHz) filters are widely used in mobile communications. This paper describes the performance index of anti-interference wireless communication technology in nuclear emergency information management in accelerator environment. The analysis of simulation and test results show that the Wi-Fi filter can meet the smooth of wireless communication in the nuclear emergency with accelerator environment. The test results show that the filter has low pass band insertion loss (less than 2.5 dB), high outof-band rejection (greater than 30 dB) and larger bandwidth (82 MHz).

Keywords: nuclear emergency; filter; insertion loss; out-of-band rejection
