Dual Band and Quad Radio Cisco Wi-Fi 7 APs

What is a Dual Band Radio?

Dual Band Radio is a radio which can operate in two bands (either 2.4/5 GHz or 2.4/6 GHz or 5/6 GHz). These radios offer the flexibility of deploying an additional radio in a particular band as per the requirement. For example, CW 9176 has a dual band radio wherein slot 0 can operate in 2.4/5 GHz mode. This provides an additional 5 GHz radio which can help distribute the client count on slot 1 which is default 5 GHz as majority clients in customer environments are 5 GHz capable.

Dual Band Radios operation

Cisco WI-Fi 7 offering- CW 9176 (High Performance deployments)

  • Slot 0- 2.4/5 GHz dual band radio This offers two 5 GHz radios or one 2.4/5 GHz radio each combination. Slot 0 when operating in 5 GHz mode can operate in UNII-1 and UNII-2 channels while slot 1 can operate in UNII-2 extended and UNII-3 channels.
  • Slot 1- Dedicated 5 GHz radio. Can operate in all 5 GHz channels when slot 0 in 2.4 GHz mode but can operate only in UNII-2 and UNII-3 channels when slot 0 in 5 GHz mode
  • Slot 2- Dedicated 6 GHz radio

Cisco Wi-Fi 7 offering- CW 9174 (Moderate to high density deployments)

  • Slot 0- Dedicated 2.4 GHz radio. Can operate in all available channels when slot 2 in 6 GHz mode but will be disabled when slot 2 is in 2.4 GHz mode.
  • Slot 1- Dedicated 5 GHz radio.
  • Slot 2- 2.4/6 GHz dual band radio. Can operate in either 2.4 GHz mode or 6 GHz mode. Slot 0 is disabled if slot 2 operates in 2.4 GHz mode.
