Section 1: Introduction Pag 1 The Netkrom CPE Unit offers a cost-effective alternative to accessing the Internet or a corporate network through expensive dedicated phone lines or fiber networks. It provides the high-performance, cost effective LANto-LAN (local area network) and LAN-to-WAN (wide area network) connectivity that is ideally suited for a wireless network or wireless Internet access. System Overview Wireless data is transmitted from a base station antenna to a receiving antenna called the Netkrom CPE Unit, or CPE for short. ( CPE stands for customer premises equipment. ). The radio signals used to send and receive data from the CPE is a line of sight signal, meaning that data can only be sent or received if there is an unobstructed path between the central Base Station or remote antenna and the Netkrom CPE Unit. Safety Precautions WARNING! Serious injury or death can occur if proper safety precautions are not taken during the installation of this equipment. The U.S. Consumer Product Safety Commission advises consumers to use the following precautions when installing an antenna.
Site Selection: Pag 2 Select a safe site to install the CPE. The distance between any power lines and the installation site should be at least one and one-half times the height of the CPE and mast assembly. Make the distance even greater, if at all possible. Since all overhead power lines look somewhat alike, consider them all dangerous and stay well away from them. If you have power lines in the area, call your local electric utility for assistance. CPE Mounting: NEVER work alone; always have someone near who can summon help. Certain clothing may provide a degree of safety, but don't depend on it for your life (rubber boots or shoes, industrial rubber gloves and a long sleeve shirt or jacket). Check weather conditions. Be sure that it hasn't rained recently and that the lawn is not wet or muddy. Make sure that rain or thunderstorms are not predicted for the day you decide to install the CPE. The wind can blow the CPE into a nearby power line. Don't install or remove CPE in moderate or heavy winds. If you need to use a ladder, make sure it is made of non-conductive (non-metallic) material. (This is a safety rule that you should follow whenever you're working with electrical equipment.) If possible, have someone present who has been trained in electric shock first aid. CPE Installation: Properly assemble the CPE according to instructions (do this where the CPE is to be put up). Once the CPE is up in full vertical position, securely fasten it by tying it to the side of the house or by using guy wires. Ground the CPE according to the National Electrical Code. Rooftop Installations: DO NOT assume that just because you're on a roof, you're isolated from ground. You may still be electrocuted or fall off the roof. Important Notes Read all instructions prior to installing any of the enclosed equipment. Pay particular attention to the warnings associated with the installation of the CPE. It is highly recommended that the installation of this equipment is done by a trained professional if you are not experienced with installation of communications equipment. Tampering with or breaking the seal on Netkrom CPE Unit back plate voids any warranty coverage on the CPE and will result in full equipment charge to the customer.
Section 2: Before You Begin Pag 3 Verify Contents of Installation Kit Take a moment to ensure you have all of the following parts in your Netkrom CPE Unit installation kit before you begin installing the CPE. If any parts are missing, please contact Netkrom at 305-4182232 CPE BRIDGE ONLY 1. AIRNET CPE Bridge Unit 2.

Cable ties and other hardware with which to secure the exterior Cat 5 cable to the CPE and building (See Secure the CPE and Cable on page 9 for illustration.)
Section 3: Selecting a Location for the CPE Pag 4 It is very important to position the Netkrom CPE and its antenna(s) to ensure the highest possible data transfer speed in all kinds of weather and in all seasons. The Netkrom CPE operates on a radio frequency of 2.4 GHz and must be line-of-sight (LOS) with its clients. Hills, buildings, trees and large vehicles must not block the signal path. Trees are especially troublesome as they may allow the signal to pass easily in winter when leaves are off, but may block the signal in the other seasons. Choose a location on the roof, tower, mast or wall for your Netkrom CPE and antenna(s) so that it has a clear shot to your base station or remote point. The closest client may not necessarily have the best path if it is blocked by hills, buildings or trees. Ensure that the signal path to each client has sufficient Fresnel zone clearance with respect to the ground or other obstacles near the path. Check the Netkrom FAQ s under Radio Propagation for more information on Fresnel zone clearance. Ensure that your mounting location is less than 100 meters from the computer, hub, switch or router location. (Maximum length of CAT-5 cable is 100 meters) Determine the building entry point ahead of time to prevent problems later.
Section 4: Installing the Netkrom CPE Unit Pag 5 This section describes how to assemble and mount your Netkrom CPE Unit. Assemble the CPE Note: Tampering with or breaking the seal on the back plate of your CPE voids any warranty coverage on the CPE. Do the following to assemble the CPE: 1. Attach the mounting bracket to the back of the CPE using the four hex screws provided. (Do not overtighten the screws.) Note: The bracket in the illustration above shows the normal orientation which allows the CPE to be pointed up towards the base station antenna. However, if you live somewhere that would require you pointing the CPE down towards the base station antenna (for example, you are on the side of a mountain in view of the base station antenna below), reverse the bracket so the Netkrom CPE Unit can be tilted downward when you aim the CPE in a later step. 2. Remove the U-bolt and pipe bracket assembly from the pink plastic. Place the washer, lock washer and nut to each side of the bolt, and then tighten until the bolts are approximately 1/4" from the end. Note: Do not tighten the screws all the way because you will need to adjust the CPE direction in a later step.
Mount the CPE Pag 6 WARNING: Netkrom strongly recommends you have a trained professional do the installation if you do not have experience installing communications equipment. If you choose to install this equipment yourself, you do so at your own risk. Do the following to mount the CPE: 1. Review the safety precautions on page 3, and make sure you have all the tools and equipment needed to install the CPE. 2. Mount the CPE in the Wall Mount Bracket and point the CPE in the approximate direction of the base station antenna or other CPE for point to point mode, then hand-tighten the nuts on the U-bolt. 3. Mount the CPE to the top of the pipe or other support and point the CPE in the approximate direction of the base station antenna or other CPE for point to point mode, then hand-tighten the nuts on the U- bolt. Note: Do not tighten the screws all the way because you will need to adjust the CPE direction in a later step.
Pag 7 4. Attach the external Cat 5 cable to the back of the CPE: place the round cable connection on the cable with the round jack on the back of the CPE, gently twist the cable until it slides down, then tighten the locking ring by turning it to the right (clockwise) until it is finger-tight. The connector has a guide key and can only go on one way. Note: It is important to keep all connections clean and dry. While the connection is water resistant, getting moisture or debris in the connection will reduce or prevent transmission speed. 1 2 Note: Do not secure the exterior Cat 5 cable to the CPE or to the building at this time. You will do this after you have completed aiming the CPE in a later step. 5. Run the exterior Cat 5 cable from the CPE into the house. Determine the Cat 5 cable length needed inside the house to reach from the wall where it enters the house to the computer. Add some slack (about 3 feet) then coil the excess Cat 5 cable. DO NOT CUT OFF THE EXCESS CABLE. WARNING! If a hole is to be made in the exterior wall of the building, use extreme caution to avoid interior wiring, plumbing and other potential hazards. If the installer is not absolutely sure of the location of potential hazards, consult a qualified electrical contractor to install the exterior Cat 5 cable. 3
Connect the Cat 5 Cable to Power Supply and PC Pag 8 Do the following to connect the CPE to the power supply and to your PC: 1. Connect the end of the exterior Cat 5 cable to the of the Power over Ethernet - PoE Injector connection marked DATA/ POWER OUT (CPE). (The PoE Injector supplies the power (Direct Current) needed to get the signal to your PC.) 2. Connect the power cord to the power supply, then connect one end of the power supply to the PoE Injector (see illustration above) and plug the power cord into a 110-240v outlet. 3. Do one of the following to connect the PoE Injector to your PC. IMPORTANT NOTE: Be sure to use the correct cable when connecting the PoE Injector to your PC or network hub. Your Internet service will not function if you use the wrong cable! If you are connecting the CPE directly to your computer, connect one end of the Cross-Ever Cat 5 cable to the open connector on the PoE Injector and the other end of the Cross-Ever Cat 5 cable to the Ethernet card in your PC. Cross-Over Cable If you are connecting the CPE to a hub or router so multiple computers can share Internet access, connect one end of the Regular Cat 5 cable to the open connector on the PoE Injector and the other end Regular Cat 5 cable to the hub or router.
Pag 9 Regular Cable Aim the CPE You will need to aim the Netkrom CPE Unit directly at the Base Station or remote antenna to achieve maximum data speed. Do the following to aim the CPE: 1. Make sure the CPE is loosely mounted, the exterior Cat 5 cable is connected to the CPE the exterior Cat 5 cable is plugged into the ANT side of the PoE Injector, and the PoE Injector is plugged in. Note: You do not need to plug the Interior Cat 5 cable into your PC network interface card to aim the CPE, but you must have the Cat 5 cable connected to the PoE Injector and the PoE Injector plugged in for your CPE to acquire the signal from the base station antenna. 2. Locate the base station antenna and aim your CPE directly toward it. Secure the CPE and Cable Do the following to secure the CPE and cable: 1. When you have completed aiming the CPE, tighten the CPE mounting bracket securely so the CPE won t move in the wind or other weather. 2. Secure the Cat 5 cable the mounting pipe or other support using wire ties or other suitable hardware.
Pag 10 3. Secure the Cat 5 cable to the outside of the house with the cable clamps and 1" stainless steel screws or other suitable hardware. Note: Create a drip loop wherever the cable changes from vertical to horizontal to prevent water from traveling down the cable and into the building. Drip Loop Drip Loop Drip Loop Note: Be careful when bending the cable in cold temperatures so the outer jacket doesn t crack. 4. Pull any excess cable into the building (except for the drip-loops), and then weather seal the hole around the Cat 5 cable by applying a quality exterior grade sealant entirely around the Cat 5 cable at the point where it enters the house. 5. Keep the remainder of the Cat 5 cable kink-free by coiling any extra cable inside and securing it with a black wire tie.
Section 5: Configuring the Netkrom CPE Unit Pag 11 Operation Mode This device provides four operational applications with Access Point, Bridge, Client (Ad-hoc) and Client (Infrastructure) modes, which are mutually exclusive. for CPE Outdoor Application, only configure in two modes: Point to Point Bridge Refer to the illustration below. While acting as Bridges, CPE in building 1 (with Station 1 being associated to) and CPE in building 2 (with Station 2 being associated) can communicate with each other through wired or wireless interface (with WDS). Thus Station 1 can communicate with Station 2 and both Station 1 and Station 2 are able to access the Internet if only CPE in building 1 or CPE in building 2 has the Internet connection. To set the operation mode to Bridge, please go to Wireless --- Basic Settings, in the Mode field click the down arrow to select AP mode. And go to Wireless --- WDS Settings to enable WDS. Note: Please make sure both CPE in building 1 and CPE in building 2 are set to the same ESSID and channel CPE Client Infrastructure If set to Client (Infrastructure) mode, this device can work like a wireless station when it s connected to a computer so that the computer can send packets from wired end to wireless interface. Refer to the illustration below. This station (CPE plus the connected computer 1) can associate to another Access Point (Base Station), and then can have the Internet access if the other Access Point (Base Station) has the Internet connection. To set the operation mode to Client (Infrastructure), please go to Wireless --- Basic Settings, in the Mode field click the down arrow to select Client mode, and then select Network Type as Infrastructure.

Pag 17 Authentication Type Fragment Threshold To provide a certain level of security, the IEEE 802.11 standard has defined two types of authentication methods, Open System and Shared Key. With Open System authentication, a wireless PC can join any network and receive any messages that are not encrypted. With Shared Key authentication, only those PCs that possess the correct authentication key can join the network. By default, IEEE 802.11 wireless devices operate in an Open System network. Wired Equivalent Privacy (WEP) data encryption is used when the wireless devices are configured to operate in Shared Key authentication mode. If the Access Point is using "Open Authentication, then the wireless adapter will need to be set to the same authentication mode. Shared Authentication is used when both the sender and the recipient share a secret key. Select Auto for the network adapter to select the Authentication mode automatically depending on the Access Point Authentication mode. Fragmentation mechanism is used for improving the efficiency when high traffic flows along in the wireless network. If your 802.11g Wireless LAN PC Card often transmit large files in wireless network, you can enter new Fragment Threshold value to split the packet. The value can be set from 256 to 2346. The default value is 2346.
Pag 18 RTS Threshold RTS Threshold is a mechanism implemented to prevent the Hidden Node problem. Hidden Node is a situation in which two stations are within range of the same Access Point, but are not within range of each other. Therefore, they are hidden nodes for each other. When a station starts data transmission with the Access Point, it might not notice that the other station is already using the wireless medium. When these two stations send data at the same time, they might collide when arriving simultaneously at the Access Point. The collision will most certainly result in a loss of messages for both stations. Thus, the RTS Threshold mechanism provides a solution to prevent data collisions. When you enable RTS Threshold on a suspect hidden station, this station and its Access Point will use a Request to Send (RTS). The station will send an RTS to the Access Point, informing that it is going to transmit the data. Upon receipt, the Access Point will respond with a CTS message to all station within its range to notify all other stations to defer transmission. It will also confirm the requestor station that the Access Point has reserved it for the time-frame of the requested transmission. If the Hidden Node problem is an issue, please specify the packet size. The RTS mechanism will be activated if the data size exceeds the value you set.. The default value is 2347. Warning: Enabling RTS Threshold will cause redundant network overhead that could negatively affect the throughput performance instead of providing a remedy. Beacon Interval DTIM Period Data Rate Preamble Type Broadcast SSID Tx Power Level This value should remain at its default setting of 2347. Should you encounter inconsistent data flow, only minor modifications of this value are recommended. Beacon Interval is the amount of time between beacon transmissions. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point). DTIM stands for Delivery Traffic Indication Message. A DTIM is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the access point has buffered broadcast or multicast message for associated clients, it sends the next DTIM with a DTIM Period value. Access point clients hear and awaken to receive the broadcast and multicast messages. The default DTIM period is 3. By default, the unit adaptively selects the highest possible rate for transmission. Select the basic rates to be used among the following options: Auto, 1, 2, 5.5, or 11 Mbps. For most networks the default setting is Auto which is the best choice. When Auto is enabled the transmission rate will select the optimal rate. If obstacles or interference are present, the system will automatically fall back to a lower rate. A preamble is a signal used in wireless environment to synchronize the transmitting timing including Synchronization and Start frame delimiter. In a "noisy" network environment, the Preamble Type should be set to Long Preamble. The Short Preamble is intended for applications where minimum overhead and maximum performance is desired. If in a "noisy" network environment, the performance will be decreased. Select enabled to allow all the wireless stations to detect the SSID of this Access Point. Select the power level to transmit packets.
IAPP Apply Change Reset Pag 19 To enable IAPP means that Access Points will communicate across the backbone network, so that mobile stations can roam between them. Press to save the new settings on the screen. Press to discard the data you have entered since last time you press Apply Change. Security Here you can configure the security of your wireless network. Selecting different method will enable you to have different level of security. Please note that by using any encryption, by which data packet is encrypted before transmission to prevent data packets from being eavesdropped by unrelated people, there may be a significant degradation of the data throughput on the wireless link. Encryption: None ( Encryption is set to None by default. ) If None is selected, you can still select to Use 802.1x Authentication and Enable MAC Authentication. To Enable MAC Authentication means to use client MAC address for authentication with RADIUS server If both Use 802.1x Authentication and Enable MAC Authentication are selected, the RADIUS Server will check MAC Authentication first; if the MAC Authentication passes, the 802.1x Authentication will be skipped. If not, the RADIUS Server will proceed to check the 802.1x Authentication. Encryption: WEP If WEP is selected, users will have to Set WEP keys either manually, or select to Use 802.1x to make the RADIUS server to issue the WEP key dynamically.
Pag 20 Set WEP key Use 802.1x Authentication Click the Set WEP Keys will prompt you a window to set 64bit or 128bit Encryption. Select HEXif you are using hexadecimal numbers (0-9, or A-F). Select ASCII if you are using ASCII characters (case-sensitive). Ten hexadecimal digits or five ASCII characters are needed if 64-bit WEP is used; 26 hexadecimal digits or 13 ASCII characters are needed if 128-bit WEP is used. If Use 802.1x is selected, then the Set WEP Key won t be usable. If Use 802.1x is selected, the Enable RADIUS Client will be automatically selected too. If Use 802.1x is selected and WEP is selected in Encryption field, then the authentication mechanism to the RADIUS Server will be TTLS. Encryption: WPA WPA: If WPA is selected, users will have to select the Authentication modes between WPA-RADIUS and Preshared Key, both modes need to have TKIP selected. (AES is not functional at present.) Pre-shared Key Pre-Shared-Key serves as a password. Users may key in a 1 to 63 characters string to set the password or leave it blank, in which the 802.1x Authentication will be activated. Make sure the same password is used on client's end. There are two formats for choice to set the Pre-shared key, i.e. Passphrase and Hex. If Hex is selected, users will have to enter a 64 characters string. For easier configuration, the Passphrase format is recommended. Group Key Refresh Time Enter the number of seconds that will elapse before the group key change automatically.
