CHAPTER 8 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.

APPENDIX C INTERFACE PORTS ETHERNET INTERFACE The ESTeem Model 195Ed’s Ethernet Port is a Full and Half-Duplex Auto-negotiation interface supporting both 10 Mbps and 100 Mbps (10/100BaseT). The Ethernet port is compliant with IEEE 802.3af Power Over Ethernet (PoE) to provide both data and power over the same CAT-5E grade Ethernet cable. The port is compatible with TIA/EIA-568B cable configuration (Figure 1).
APPENDIX C INTERFACE PORTS CONFIGURING DHCP SERVER The ESTeem 195Ed Ethernet port supports both client and server Dynamic Host Configuration Protocol (DHCP). Figure 2 shows the DHCP host configuration screen that will be shown if DHCP server is selected in the setup screens. Enter the values that match the DHCP configuration for your network.
APPENDIX C INTERFACE PORTS RS-232C PROGRAMMING PORT CONFIGURATION RS-232 Programming Port The ESTeem Model 195Ed has a proprietary RS-232C interface in a RJ-45 connector on the front panel. To interface the 195Ed to the serial port on the computer, you need ESTeem cable AA0621 that combines a standard Ethernet patch cable to a 9-pin Female adapter. The serial port on the ESTeem Model 192E can be used to access the configuration menu in the ESTeem for system and network configuration.
APPENDIX D RADIO CONFIGURATION 195Ed FREQUENCY OF OPERATION In a wireless Ethernet network all of the ESTeem Model 195Ed’s must be set to the same radio frequency of operation or channel. Listed on the right is a table showing the channel and corresponding frequency of operation. The frequency of operation is selectable when configuring the mode of operation of the 195Ed (reference Chapter 4). See Figure 1.
APPENDIX D RADIO CONFIGURATION Figure 2: Advanced Data Rate Selection RF BASIC RATE The RF Basic Rate is the synchronization rate used to establish the initial connection between 802.11g and 802.11b communication devices in Mbps. After the initial connection has been establish the RF communication rate will be determined by the RF Communication Data Rate established above. Factory default is 1 through 11 Mbps shown in Figure 2 so that the unity will establish communication with the older (slower) 802.
APPENDIX E SECURITY OVERVIEW The security for the ESTeem Model 195Ed, like all network security, must be multi-layered. One level of security is never enough to make sure that data does not end up in the wrong hands. Please review the following security levels and decide what is the most appropriate for your network. 128-BIT WEP The 128 WEP uses a particular algorithm called RC4 encryption to encode and decode traffic that is based on a 104-bit encryption key and a 24-bit Initialization Vector (IV).
APPENDIX E SECURITY Using a combination of both the WPA or 128-Bit WEP encryption and the ACL filter provide the ESTeem an extremely secure wireless networking layer. DISABLING BROADCAST PROBES AND HIDING SSID A simple but very effective way of securing a network is to make the network difficult to find. By disabling broadcast probes and hiding the Service Set Identification (SSID), wireless and network “sniffers” will not be able to find your ESTeem Model 195Ed network.
APPENDIX F TROUBLESHOOTING TESTING COMMUNICATION LINK After you have configured at least two of the Model 195Ed wireless Ethernet modems for operation, you can verify communication with each the following steps: Status LED Solid Red on Link Status Light The quickest source of link status is to view the Status Light on the face of the 195Ed (Figure 1). If the Status light is solid on any other 195Ed except the Timing Master, the Model 195Ed has a connection to another Model 195Ed listed in the Peer Table.
