I am doing a design that has a WL18xx wifi module (2.4 GHz) and a gsm / lte module (824-960 / 1710-1990 MHz).
My problem is that I don't have space to keep half the wavelength between both antennas.
But my point is that if both RF systems operate in different RF bands (2.4 GHz for wifi and 824-960 / 1710-1990 MHz for GSM), there is no interference regardless of the distance between both antennas.
Please, am I right or wrong?
Can I place both antennas at a distance of less than half the wavelength?
Thank you very much!
