CHAPTER 4 CONFIGURATION SETUP PROGRAMMING EXAMPLE Listed in this chapter we will give you an overview programming the most common use of the Model 195Eg, as a wireless Access Point Bridge to a hardwired LAN with Repeater Enabled. In these examples we will program the Model 195Eg from the unit’s Web Configuration Manager’s Setup. Access Point Bridge with Repeater Enabled 1. Review the Access Point Bridge diagram. See Figure 1. Figure 1: Access Point Bridge Diagram 2.
CHAPTER 4 CONFIGURATION SETUP 5. From the Model 195Eg Top menu select Setup. From the Select Mode of Operation pull down box , select AP Bridge and push the Next button below the pull down box. You will now see the screen shown in Figure 2. Note: Throughout the Configuration Manager are Help Screens that can accessed for further information on each item. Figure 2: Access Point Bridge Setup Screen 6. Select Yes if you want to use Dynamic Host Configuration Protocol (DHCP) client services.
CHAPTER 4 CONFIGURATION SETUP 7. Enter the IP Address and IP Netmask for the Model 195Eg. If you want to be able to access the Model 195Eg over the Ethernet network for diagnostics and updates the IP address must be on the same network as the other Ethernet devices. Reference Figure 4. Figure 4: IP Address Setup Screen 8. Enter the DNS server information. If you are not connecting the Model 195Eg to the Internet, leave blank and press the Next button. Figure 5.
CHAPTER 4 CONFIGURATION SETUP 9. Select if you will be using security for your wireless network. Enter the SSID for you 802.11g network. The SSID is the unique identification for your wireless network and all 802.11g devices that share a wireless network MUST have the same SSID code. This identification code is case sensitive and must NOT contain spaces. Reference Figure 6. Figure 6: SSID Setup Screen 10. Select the encryption level for the wireless network.
CHAPTER 4 CONFIGURATION SETUP 11. Continue through the configuration screens using the Help menus for further questions until you reach the Commit Changes menu screen. Press the Commit Changes button and Model 195Eg will save your configuration, reboot the unit, and operate with the commands you have selected. Reference Figure 8.
CHAPTER 5 REPEATING FEATURES The Repeating Feature in the Model 195Eg is used to increase the wireless network area of coverage for both indoor and outdoor applications without the cost of hardwiring the Access Points to a common LAN. This custom feature is unique to the Model 195Eg because conventional 802.11b/g Access Points have to be interfaced to a common network either by hardwire, see Figure 1, or a dedicated point to point RF backbone.
CHAPTER 5 REPEATING FEATURES Learning Phase. After an approximate 10-second period after no further additions to the Mac addresses in the repeater beacons, the Model 195Eg goes into the learning phase. In this phase all Model 195Eg units calculate their routes to the other Model 195Eg units in the network using the lowest “path cost”, meaning shortest number of hops, back to the Root Bridge. Note: The Root Bridge in a network should be the Model 195Eg where the majority of the data flow is processed.
CHAPTER 5 REPEATING FEATURES Using the Access Control List (ACL) In Network Design As mentioned above, the shortest route to the Root Bridge may not be the best radio path. As seen in Figure 2 the radio path from Pump Site D to the Water Plant – Site A has a marginal link. Although the shortest route from Pump Site D to the Water Plant is direct, the best radio path is using the repeater site at Tank Site B.
CHAPTER 6 ANTENNA SETUPS ANTENNA AND CABLE CONFIGURATIONS Warning: Only the tested cable lengths and antennas provided by EST meet the FCC maximum peak output power requirements. Any other combination of antennas or coax cables is not authorized. EST offers different types of antennas for both indoor and outdoor configurations. Antenna Port A Part Number: AA01S • Omni-directional, rubber duck, direct mount, unity gain antenna. • Indoors and short range outdoor applications.
CHAPTER 6 ANTENNA SETUPS COAXIAL CABLE ATTENUATION Listed below are representative cable losses in db/100 ft at the 2.4 GHz frequency range: Feedline Type RG-8 (Solid) LMR 600 3/8" Heliax 1/2" Heliax 7/8" Heliax 1.25" Heliax Note: Attenuation (dB/100 ft.) @ 2.4 GHz 7 4.4 6.5 3.5 2 1.6 A -3 dB loss means you have lost 1/2 of your signal or transmitter power. A +3 dB gain means you have doubled (x2) your signal or transmitter power.

CHAPTER 6 ANTENNA SETUPS FRESNEL ZONE The Fresnel zone shows the ellipsoid spread of the radio waves around the visual line-of-sight after they leave the antenna (see figure above). This area must be clear of obstructions or the signal strength will be reduced due to signal blockage. Typically, 20% Fresnel Zone blockage introduces little signal loss to the link. Beyond 40% blockage, signal loss will become significant. This calculation is based on a flat earth.
