Cisco Business 140AC 5-Pack Overview

The Cisco Business 140AC is a wireless access point sold as a five-unit pack. Each unit supports IEEE 802.11a/b/g/n/ac standards and delivers up to 867 Mbps on the 5 GHz band. A single Gigabit Ethernet port with Power over Ethernet simplifies installation. The ceiling-mountable design targets small to medium business environments needing multiple managed access points.

Suited For Multi-AP Deployments

This pack suits IT teams deploying a cohesive wireless network across several rooms or floors where centralised management and PoE cabling are preferred. Buyers who need only a single access point or require a functional console port for direct CLI access should consider other options. The RJ-45 console port on these units is not functional.

867 Mbps 5 GHz Throughput Decides Fit

The 802.11ac Wave 2 radio tops out at 867 Mbps on 5 GHz using MCS0-MCS9 modulation. Networks with high-density client loads or bandwidth-heavy applications may exceed this ceiling. If the expected per-user throughput must exceed that figure, a higher-tier access point is required.

Highlights

  • Supports 802.11ac Wave 2 for up to 867 Mbps on 5 GHz
  • MU-MIMO serves multiple clients simultaneously for smoother performance
  • Gigabit Ethernet with PoE simplifies installation and power
  • Ceiling-mount design fits discreetly in office environments
  • Dual-band antennas provide 2 dBi at 2.4 GHz and 4 dBi at 5 GHz

FeaturesMU-MIMO
Multi-User (MU) Multiple-Input Multiple-Output (MU-MIMO) technology allows transmission of data to multiple 802.11ac Wave 2–capable clients simultaneously to improve the client experience. Prior to MU-MIMO, 802.11n and 802.11ac Wave 1 access points could transmit data to only one client at a time, typically referred to as Single-User MIMO (SU-MIMO).
802.11ac Wave 2 with 2x2:2 MIMO technology uses two spatial streams when operating in SU-MIMO or MU-MIMO mode, offering 867-Mbps rates for more capacity and reliability than competing access points.

Questions about this item

How much heat does the 5-CBW140AC-B generate when running continuously in a ceiling mount?

The access point operates between 0°C and 50°C (32°F to 122°F) with 10% to 90% non-condensing humidity, and its compact 1.30" x 6.00" x 6.00" form factor passively dissipates heat without a fan.

Does the 5-CBW140AC-B require a PoE switch or injector to power all five units?

Each unit draws power through its single Gigabit Ethernet port using Power over Ethernet, so a PoE-capable switch or mid-span injector is needed for every access point in the pack.

Will legacy 802.11a/b/g clients connect reliably to the 5-CBW140AC-B alongside newer 802.11ac devices?

Yes, the radio supports 802.11a/b/g rates from 1 to 54 Mbps and 802.11n up to 300 Mbps on 2.4 GHz, while 802.11ac Wave 2 clients use MU-MIMO up to 867 Mbps on 5 GHz.
