9/13/2006 Salar 2.4 GHz 802.11n Ceiling Mount Omni Specification Document Number: EDCS-520849 Revision: 2.0 Author: Steve Saliga Manager: Fred Anderson Technical Specification for the Salar 2.4 GHz 802.11n Ceiling Mount Omnidirectional Antenna Headline This document outlines the technical requirements for a 2.4 GHz plenum rated antenna to be used with Cisco Aironet 802.11n and/or pre-802.11n capable access points. This antenna is built with three (3) radiating elements and three plenum rated cables. The antenna is designed to mount to a grid-style ceiling system employing T-rails or “Trimline” channel-type system. A printed version of this document is an uncontrolled copy. Cisco Systems, Inc.

9/13/2006 Salar 2.4 GHz 802.11n Ceiling Mount Omni Specification 1. Introduction This document describes the complete set of required specifications for a plenum rated antenna for 2.4 GHz pre-802.11n and 802.11n 3-antenna access points. The radiating elements are simple monopole elements above a ground plane, and each element is fed with its own cable. The entire antenna will be composed of three such elements, each spaced about 4 inches (center-to-center) apart, or about 0.83 wavelengths. Each cable is 3-ft long, off-white and plenum rated, built with a reverse polarity-TNC connector. The radome will be based on those used for previous Cisco antenna products so that it has the same “family” look and feel. 2. Antenna Electrical Specifications The electrical specifications for this antenna are summarized in Table 1 below. All the manufacturer’s specifications should be reported in data sheet format. Electrical Specifications Minimum Maximum Parameter Design Goal Notes Acceptable Acceptable 1 Antenna Type Omnidirectional Operating 2402 - 2485 2 Frequency MHz Range Nominal Input 3 50 Ω Impedance 1.5:1 VSWR 2385 - 2515 4 Bandwidth MHz (1) 45-degree Downtilt. 5 Peak Gain 3 dBi (2) Gain could be as high as 4 dBi 6 Polarization Linear The E-plane beamwidths of the elements vary E-Plane 3 dB based on position on the 7 60 Degrees Beamwidth ground plane. 60- degrees is close to all values in one plane H-Plane 3-dB 8 Omnidirectional Beamwidth Front-to-Back 9 10 dB Ratio Table 1 Summary of Antenna Electrical Specifications A printed version of this document is an uncontrolled copy.

9/13/2006 Salar 2.4 GHz 802.11n Ceiling Mount Omni Specification 3. Mechanical and Environmental Specifications The mechanical specifications will cover the physical appearance of the antenna as well as all mounting, cable and connectors. The mechanical and environmental specs are summarized in Table 2. A model of the antenna housing is shown in Figure 1 and Figure 2 shows the radiating elements inside the radome. The proposed ground plane is 4” x 12”. Each antenna needs about 4” x 4” to give the sort of performance we are looking for so that yields spacing between each antenna of about 0.83 wavelengths.
