High-Performance Indoor Coverage for Cisco Access Points

The Cisco AIR-ANT2535SDW-RS is a compact, short dual-band omnidirectional antenna engineered for high-efficiency indoor wireless deployments. Designed to operate simultaneously over 2.4 GHz and 5 GHz Wi-Fi bands, it delivers consistent 360° coverage for environments requiring stable connectivity. This "RS" model features a unique Self-Identifying Antenna (SIA) capability via an integrated EEPROM, allowing the Cisco Catalyst 9120AXE Access Point to automatically detect the antenna type and gain, ensuring optimal configuration without manual tuning.

Key Benefits & Features

• Dual-Band Operation: Supports 2.4–2.5 GHz and 5.15–5.925 GHz frequencies for flexible, high-performance indoor coverage across legacy and modern networks.
• Optimized Gain: Provides 3 dBi (2.4 GHz) and 5 dBi (5 GHz) peak gain to enhance signal strength, range, and wireless stability.
• Self-Identifying Capability (SIA): Integrated circuitry allows Cisco Catalyst 9120AXE series APs to auto-configure antenna gain and type (requires Catalyst 9800 controller with IOS-XE 17.4.1+).
• Omnidirectional Pattern: Delivers uniform 360° coverage with a 35° elevation beamwidth to reduce dead zones.
• Easy Identification: Features a purple color marking to distinguish it as an SIA-enabled model (compared to the orange-marked non-SIA version).
• Durable Design: UV-stable white housing with a Male RP-TNC connector for secure, tool-free installation.

Ideal Use Cases

• Indoor enterprise Wi-Fi deployments using Cisco Aironet or Catalyst APs.
• High-density office environments requiring uniform wireless coverage.
• Deployments utilizing the Cisco Catalyst 9120AXE where auto-provisioning is desired.
• Indoor areas where compact antennas and minimal visual impact are preferred.
