Legacy Open Mesh: A60 Versus A62 Device Comparison

Follow

Topic

This article discusses the differences between the A60 and A62 access points.

Environment

  • Open Mesh A60 access points
  • Open Mesh A62 access points

Description

The Difference

The A60 is a dual-band, 802.11ac Wave 1 wireless access point. The maximum theoretical throughput is 1300Mbps on the 5 GHz band, 450 Mbps on the 2.4 GHz band, for a total combined theoretical throughput of 1750 Mbps (1.7 Gbps).

The A62 is a tri-band, 802.11ac Wave 2 wireless access point. It supports up to 1734 Mbps on the 5 GHz bands combined and 300Mbps on the 2.4 GHz band, for a total combined theoretical throughput of 2034 Mpbs (2 Gbps).

802.11ac Wave 1 vs. Wave 2

  • 802.11ac Wave 1 supports MIMO, up to an 80 MHz channel width, and up to three spatial streams of data transmitting simultaneously.
  • 802.11ac Wave 2 supports MU-MIMO, up to a 160 MHz channel width, and up to four spatial streams.

Tri-band over Dual-band

Dual-band operates with two radio bands to service both 2.4 GHz and 5 GHz clients. The AP62 uses a Tri-band configuration, which includes an additional 5GHz radio for greater functionality in a high-density environment and service for a wider margin of devices.

MIMO / MU-MIMO

MIMO (Multiple-Input and Multiple-Output) uses multiple antennas on the access point, to transmit and receive multiple spatial streams of data simultaneously. The access point streams data to one client at a time under MIMO.

MU-MIMO (Multi-User Multiple-Input and Multiple-Output) connects to multiple clients at the same time to achieve a faster WiFi network.
