"Broadband Hybrid for WiFi" and "Multi-band H

Hello All,

I am a new guy for RF circuits and systems and now chosing the FYP topic for my final year.

When I am seeing "Broadband Hybrid for WiFi" and "Multi-band Hybrid for WiFi", I have a few questions.

Q1: What is the difference between "Broadband Hybrid" and "Multi-band Hybrid" ?

Q2: For Wifi, ISM bands are at 2.4, 5.2 and 5.8GHz. Does the former one cover all of the bands simultaneously and teh latter one choose one of the band seperately ?

Thanks for your explanation. :D
