What Is the AIR-ANT2535SDW-RS=? Cisco’s 2.4/5 GHz Dual-Band Omni Antenna Demystified

Overview of the AIR-ANT2535SDW-RS=

The ​​AIR-ANT2535SDW-RS=​​ is a ​​dual-band omnidirectional antenna​​ from Cisco’s Aironet series, designed to support both 2.4 GHz and 5 GHz frequencies. Ideal for indoor or sheltered outdoor deployments, it provides 360° coverage for environments requiring flexible, high-density Wi-Fi, such as offices, hospitals, or retail spaces.

Core Technical Specifications

• ​​Frequency support​​: Dual-band (2.4 GHz for 802.11b/g/n; 5 GHz for 802.11a/n/ac).
• ​​Gain​​: 5 dBi (2.4 GHz) and 6 dBi (5 GHz) for balanced coverage and throughput.
• ​​Polarization​​: Dual-slant polarization to minimize signal degradation.
• ​​Mounting​​: Ceiling or wall-mountable with integrated RP-TNC connectors.

Key Advantages for Network Deployments

• ​​Versatility​​: Supports ​​simultaneous dual-band operation​​, reducing the need for separate antennas.
• ​​Uniform coverage​​: Omnidirectional pattern ensures consistent connectivity across open floor plans.
• ​​Compatibility​​: Works with Cisco Aironet 1800, 2800, 3800, and 4800 Series access points.

Addressing Critical User Questions

Q: Can this antenna handle high client density?

Yes. Its dual-slant polarization improves signal reliability in crowded areas, making it suitable for ​​50+ concurrent devices​​ per AP.

Q: Is it suitable for outdoor use?

Limited to ​​sheltered outdoor deployments​​ (e.g., covered patios). For harsh environments, consider weather-hardened models like AIR-ANT2547V-N.

Ideal Use Cases and Installation Tips

• ​​Conference rooms​​: Ensure ceiling-mounted placement for optimal 360° coverage.
• ​​Multi-story buildings​​: Deploy on alternating floors to minimize interference.
