Question

In Dual connectivity Does modem use two RF unit ?

Answer 1

A dual Wi-Fi antenna is a pair of identical antennas on a wireless router or Wi-Fi-equipped device, intended to eliminate signal fading and dead spots. Dual Wi-Fi antennas operate on a principle known as antenna diversity, which offers two different reference points for signal reception or transmission (or both) and uses the better one. These systems all operate on the principle of antenna diversity, which engineers have exploited in long-distance communications systems for decades.
