Meraki Antennas

Enhancing Wireless Connectivity with Cisco Meraki Antennas

Technical Overview and FAQs

Cisco Meraki outdoor and indoor access points support the use of external antennas to optimize signal coverage patterns. This article delves into the technical aspects of antennas used with Meraki access points, covering properties, types, compatibility, and deployment considerations.

Relevant Properties of Antennas:

  1. Gain: Measured in decibels (dBi), gain indicates the ability of an antenna to focus radio frequency (RF) energy in specific directions. Real antennas, even omnidirectional ones, exhibit some gain compared to a perfect isotropic radiator. Gain values vary depending on antenna type and frequency band.

  2. Directionality: Antennas exhibit varying degrees of directionality, directing RF energy in specific patterns. While omnidirectional antennas radiate signal uniformly in all directions, directional antennas focus signal into narrower coverage areas, suitable for point-to-point links or targeted client deployments.

  3. Polarization: Refers to the orientation of electric fields in RF signals. Matching antenna polarizations maximize signal strength. Outdoor antennas, particularly for longer-range connections, often feature both vertical and horizontal polarization elements.

Difference between Antenna Types:

Cisco Meraki offers three main antenna types:

  • Omnidirectional: Radiates and collects RF signals in all directions, suitable for broad coverage areas.
  • Patch: Flat, square or rectangular antennas focusing RF energy in specific directions.
  • Sector: Similar to patch antennas but with a more focused coverage area, ideal for longer-range connections.

Each type may be single-band, dual-band, or tri-band, supporting different frequency ranges for optimal performance.

Deployment Considerations:

  • Wall-Mounting: Meraki APs with internal antennas can be wall-mounted vertically, although optimal placement is typically horizontal. Signal coverage patterns should be reviewed for both radios.
  • Compatibility: Different models of antennas are supported by specific Meraki access points. It's essential to consult datasheets for compatibility and coverage pattern details.
  • New Antenna Technologies: Cisco's tri-band antennas, such as the CW-ANT-O1-NS-00 (omnidirectional) and CW-ANT-D1-NS-00 (patch), offer enhanced performance across 2.4GHz, 5GHz, and 6GHz bands. These smart antennas self-identify to the access point and provide optimized signal coverage.


  1. Compatibility with Older Access Points: New WiFi-6E antennas should not be used with older access points, and vice versa, to ensure optimal performance and regulatory compliance.
  2. Supported Antennas: Meraki offers a range of outdoor antennas, including omnidirectional, patch, and sector types, each designed for specific use cases and frequency bands.
  3. Details of New Antennas: The CW-ANT-O1-NS-00 and CW-ANT-D1-NS-00 are tri-band smart antennas tuned for 2.4GHz, 5GHz, and 6GHz bands, offering enhanced performance and self-identification capabilities.
  4. Mounting and Accessories: Antennas come with comprehensive accessory kits for mounting and installation, ensuring ease of deployment and integration with Meraki access points.

Conclusion: Cisco Meraki antennas play a crucial role in optimizing wireless connectivity, providing flexibility, and enhancing performance across diverse deployment scenarios. Understanding antenna properties, types, and compatibility ensures efficient deployment and reliable network operation, contributing to seamless connectivity experiences for users.
