Introduction The Senao access point is designed to perform in a variety of environments. Implementing the antenna system can greatly improve coverage and performance. A good communication can only be achieved with the right antenna. The antenna kits comprise numerous components, including the antenna, connectors, mounting hardware, antenna cabling, and in certain product boxes. 2. Type of Antennas The Senao access point may be bundled with several different styles of antennas for use in the 2.4GHz range. Each type of antenna will offer different coverage capabilities. As the gain of an antenna increases, there is some tradeoff to its coverage area. Usually high gain antennas offer longer coverage distances, but only in a certain direction. The radiation patterns below show the coverage areas of the styles of omni-directional and uni-directional antennas. Omni-Directional Antennas An omni-directional antenna is designed to provide a 360-degree radiation pattern. This type of antenna is used when coverage in all directions from the antenna is required. Figure 1-1: Omni-Directional Antenna (top-view) Directional Flat Panel Antennas 2 Directional antennas have many different styles and shapes. By redirecting this energy, it has the effect of providing more energy in one direction, and less energy in all other directions. As the gain of a directional antenna increases, the angle of radiation usually decreases, providing a greater coverage distance, but with a reduced coverage angle. Figure 1-2: Directional Flat Panel Antenna (side view) 3. Antenna placement The advices below are basic concepts to install an antenna. „ The distance between the antenna and transceiver should be kept to a minimum to reduce signal loss. „ To operate at optimum efficiency, antenna cable should be kept as short as possible. 3 4-1. Hardware Description The 3dBi omni-di rectional antenna is a broadband antenna for the 2.4GHz frequency band featuring an omni-directional pattern with a normal gain of 3dBi. Before you start installing the antenna, verify the following items in the antenna kits or in the product package.

Installing the 3dBi omni-di rectional antenna Figure 1-3 Elements list 4-2. Mounting the Omni-directional Antenna You can mount the 3dBi antenna to a ceiling for indoor use. This antenna uses vertical polarization that is the most common type of polarization for omni-directional antennas. Mounting to a ceiling In most cases, these installations require a large coverage area. Experience has shown that an omni-directional antenna mounting at about 6 to 8 meter (20 to 26 feet) will typically provide the best overall coverage. Of course this also depends upon the height of the ceiling, material on the ceiling and ability to locate the antenna at this height. The antenna should be placed in the center of the desired coverage area. An open area will provide the best performance. To mount the antenna to a ceiling proceed following steps 1. Position the ferrule (item B in Figure 2-11) to the front of the bracket (item H). 2. Place antenna mounting screws (item F) through the screw hole on the bracket. 3. Use the lock – washers (item G) and nuts (item C) to secure the bracket to the ferrule (item B). Use a wrench to tighten the nuts and ensure the ferrule will be fixed 6 to the front of the bracket. 4. Feed the omni-directional antenna (item A) through the hole of the ferrule (item B) 5. Push the antenna through the ferrule (item B) to the end. Place screw (item E) to tighten the antenna. Note The hole of the antenna should be above the ferrule.(See figure 1-4) 6. Attach the cable (item I) and Jack (item J) to the connector on top of the antenna. 7. Place 3 screws (item D) through the holes to fix the antenna on the ceiling. 8. Attach the other end of the cable (item I) to the access point or the PC card of the access point.

Introduction 2.4 GHz frequency band is regarded specially as a dangerous band for its heating harmfulness to the human body. That’s why microwave oven is operating in this frequency band. The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC), and the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. 2. Classification The antenna of the product, under normal use condition, is at least 20 cm away from the body of the user. Warning statement for keeping 20 cm separation distance and the prohibition of operating next to a person has been printed on the users manual. So, this product is classified as the Mobile Device. 3. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b).
