1 Stage 1: ROKKOO SMART BAND creation of an electromagnetic field with a strength of 5.10 and 15 V / m at frequencies 450, 900.1800 and 3000 MHz (unmodulated sinusoidal signal) at the location of the field sensor.
Stage 2: field strength measurements when the field sensor is located in the center of the Smart band device.
Measuring equipment
High Frequency Generator E8257D
Field sensor 7060FP Kit with virtual field monitor VM 7000
System for testing for immunity to radio frequency electromagnetic field, consisting of: amplifier 150 W 1000; radiating antenna CBL 6140A
The test results are presented in the table:
Frequency in MHz
Field strength, V / m without “Smart band”
Field strength, V / m with “Smart band”
Field attenuation in%
The attenuation of the electromagnetic field when using the Smart band device at frequencies from 450 to 3000 MHz is from 51 to 98%, depending on the frequency and magnitude of the field strength.
