System Overview Chapter 2 A system is made up of one to six Base Stations that make up a Hub (or cell) with each Base Station communicating with their associated SUs (Subscriber Units). Together, they provide a wide coverage, high-capacity system that transfers IP traffic between the Hub and its multiple SUs. Each Hub has the ability to communicate in all directions using up to six sectors of 60 degrees each. Each of the Hubs six sectors has the capability of communicating 20, 30, 40 or 60 Mbps in total bandwidth allowing a maximum of 360 Mbps per Hub. Figure 2-2-1: Each HUB is made up of one to six Base Stations and multiple remotes(SUs) Uplink and Downlink, each SU communicates with it Hub in a coordinated manner so that all other remotes within its Hubs jurisdiction. All SUs are very quickly handled on a case by case basis giving the user at the SU that they are in constant communication with its Hubs Sector. 2-1 T S U N A M I M U L T I P O I N T Site Planning Considerations The installation of a wireless network requires much the same basic planning as any wired network. The main difference is that the wireless signal requires some additional planning. This planning includes RF path planning, site preparation, and installation of outdoor components such as outdoor units, antennas, lightning protection devices, and cabling suitable for outdoor conditions. Although the technology implemented in this broadband fixed wireless system can make use of multipath signals, reducing the effect of obstructions in the path, it is important that the characteristics of the path be carefully examined. With this knowledge, components and network requirements can be correctly planned for your specific application. This chapter provides insight into the planning necessary to prepare your site for your broadband fixed wireless system. General Considerations A basic consideration is the physical location of the sites at each end of the link. Because microwave signals travel in a straight line, a clear line of sight between antennas is ideal. Frequently, however, the locations of the desired links are fixed. When a clear line of sight cannot be achieved, you must plan accordingly. Other general site considerations include:

a. Will a tower have to be constructed? Are permits required?

b. Possibility of future obstructions-Will trees grow high enough to interfere with the signal? Are there plans to erect buildings between the sites that may obstruct the path?

c. Availability of grounding-Good grounding is important in all areas of the world, but in areas prone to lightning, it is especially critical. d. Availability of power-Are redundant power systems available if the area is prone to outages?

The planning of a wireless link involves collecting information and making decisions. The following sections will help you determine which information is critical to the site and will be an aid in the decision-making process. 2-2 T S U N A M I M U L T I P O I N T Weather It is important to research any unusual weather conditions that are common to the site location. These conditions can include excessive amounts of rain, wind velocity or extreme temperature ranges. If extreme conditions exist that may affect the integrity of the radio link, it is recommended that these conditions be taken into consideration early in the planning process. RAIN Except in extreme conditions, attenuation (weakening of the signal) due to rain does not require serious consideration for frequencies up to the range of 6 or 8 GHz. When microwave frequencies are at 10 or 12 GHz or above, attenuation due to rain becomes much more of a concern, especially in areas where rainfall is of high density and long duration. The systems discussed in this manual operate at frequencies below 6 GHz, so rain is not a concern. Temperature can adversely affect the radio link when such as temperature inversion, or very still air accompanied by stratification. Temperature inversion can negate clearances, and still air along with stratification can cause severe refractive or reflective conditions, with unpredictable results. Temperature inversions and stratification can also cause ducting, which may increase the potential for interference between systems that do not normally interfere with each other. Where these conditions exist, it is recommended that shorter paths and adequate clearances are used. WIND Any system components mounted outdoors will be subject to the effect of wind. It is important to know the direction and velocity of the wind common to the site. Antennas and their supporting structures must be able to prevent these forces from affecting the antenna or causing damage to the building or tower on which the components are mounted. Antenna designs react differently to wind forces, depending on the area presented to the wind. This is known as wind loading. Note For definitions of wind loading specifications for antennas and towers, refer to TIA/EIA- 195 (for antennas) or TIA/EIA-222 (for towers) specifications. LIGHTNING The potential for lightning damage to radio equipment should always be considered when planning a wireless link. A variety of lightning protection and grounding devices are available for use on buildings, towers, antennas, cables, and equipment, whether located inside or outside the site, that could be damaged by a lightning strike. Lightning protection requirements are based on the exposure at the site, the cost of link down-time, and local building and electrical codes. If the link is critical, and the 2-3 T S U N A M I M U L T I P O I N T site is in an active lightning area, attention to thorough lightning protection and grounding is critical. LIGHTNING PROTECTION To provide effective lightning protection, install antennas in locations that are unlikely to receive direct lightning strikes, or install lightning rods to protect antennas from direct strikes. Make sure that cables and equipment are properly grounded to provide low-impedance paths for lightning currents. Install surge suppressors on adjacent telephone lines and power lines. Recommended is lightning protection for cables leading to the wireless ODU to/from the power brick. The lightning protection should be placed at points close to where the cable passes through the bulkhead into the building, as well as near the ODU. CAT5 CABLE When the entire control cable, from the building entrance to the ODU, is encased in steel conduit, no surge arrestors are required. Otherwise, each control cable requires one surge arrestor within two feet of the building entrance. Note For installations with several radios, it may be more convenient to use a Type-

66 punch block with surge arrestors. A Type-66 punch block can accommodate up to 25 conductor pairs. INTERFERENCE An important part of planning your broadband fixed wireless system is the avoidance of interference. Interference can be caused by effects within the system or outside the system. Good planning for frequencies and antennas can overcome most interference challenges. Co-Channel and Adjacent Channel Interference Co-channel interference results when another RF link is using the same channel frequency. Adjacent-channel interference results when another RF link is using an adjacent channel frequency. In selecting a site, a spectrum analyzer can be used to determine if any strong signals are present at the site and, if they are, to determine how close they are to the desired frequency. The further away from your proposed frequency, the less likely they are to cause a problem. Antenna placement and polarization, as well as the use of the built-in high-gain, low-sidelobe antennas, is the most effective method of reducing this type of interference. 2-4 T S U N A M I M U L T I P O I N T Antennas Antennas frequently play a key role in reducing the potential for interference. They come in a variety of configurations that have different performance characteristics in the areas of gain and directionality. Antennas that transmit/receive in all directions are known as omni-directional, while those that transmit/receive in one specific direction are categorized as directional. Antennas also vary in beamwidth, which is the aperture to which they can see signals. Larger antennas typically provide narrower beamwidths and can diminish interference from nearby transmitters by:

Focusing RF energy from the intended destination Reducing the power of interfering sources not directly aligned to the antenna Antennas: the narrower, the better Tsunami Multipoint Ethernet Systems use integrated directional antennas that transmit and receive a relatively narrow beamwidth of radio energy, improving system performance by reducing the likelihood that surrounding RF clutter will interfere with reception. The antennas with this system are directional and can not be detached. Type:

Elevation:

Base Stations Flat-panel antenna 60-degree 6-degree Subscriber Units Flat-panel antenna 10-degree 10-degree Even when other licensees are not an issue, if you are using a network deployment using the "cell" approach, all these considerations are still important to reduce interference between your own adjacent installations. Antennas are tuned to operate on a specific group of frequencies. Tsunami Multipoint offers a variety of channel plans that provide a flexible tool for overcoming present and future interference. Four non-overlapping 20 MHz channels (six total directional channels) can be used to avoid existing traffic in the 5.8 GHz frequency band. If one part of the 5.8 GHz spectrum is occupied when Tsunami Multipoint is initially deployed, another frequency channel can be selected to bypass the interfering signal. If interference arises after deployment, another frequency channel plan can be selected to steer around the impacted channel. Beamwidth and gain have been optimized in this equipment. ANTENNA POLARIZATION The Tsunami Multipoint system uses left-hand circular polarization. As a result, the signal is successfully received regardless of the orientation of the antenna. Circular polarization also provides protection against multipath degradation of the signal quality. 2-5 T S U N A M I M U L T I P O I N T TOWERS When planning antenna placement, it might be necessary to build a free-standing tower for the antenna. Regulations and limitations define the height and location of these towers with respect to airports, runways, and airplane approach paths. These regulations are controlled by the FAA. In some circumstances, the tower installations must be approved by the FAA, registered with the FCC, or both. To ensure compliance, review the current FCC regulations regarding antenna structures. These regulations (along with examples) are on the FCC web site at wwwfcc.gov/wtb/antenna/. Path Planning To get the most value from a wireless system, path planning is essential. In addition to the fact that radio signals dissipate as they travel, many other factors operate on a microwave signal as it moves through space. All of these must be taken into account, because any obstructions in the path will attenuate the signal. CALCULATING A LINK BUDGET A link budget is a rough calculation of all known elements of the link to determine if the signal will have the proper strength when it reaches the other end of the link. To make this calculation, the following information should be available:

The minimum antenna height at each end of the link for paths longer than seven miles

(for smooth terrain without obstructions) is the height of the First Fresnel Zone plus the additional height required to clear the earth bulge. A signal degrades as it moves through space. The longer the path, the more loss it experiences. This free-space path loss is a factor in calculating the link viability. Free-

space path loss is easily calculated for miles or kilometers. Availability represents the quality of a link. It is the ratio of the time that the link is available to the total time. This serves as a guide to the service that you can expect, on average, over a period of one year. Table 2-2 shows how percentage availability relates to outage time per year. Note: use the path planning tools located on the WMUX web site: www.wmux.com Note You can lower the bit error rate (BER), resulting in greater reliability, by reducing the data throughput or reducing the distance. Unlicensed Frequencies-U-NII The FCC has identified the frequencies from 5.725 to 5.825 GHz as Unlicensed National Information Infrastructure (U-NII). This band can be used by anyone 2-6 T S U N A M I M U L T I P O I N T without having to obtain a license. However, you must use radio equipment that is

"type approved" by the FCC or local government for use within the specific band. 2-7 T S U N A M I M U L T I P O I N T Chapter 3 3. Quick Set-up Procedure Please read this section completely before attempting to install any software, test or operate this system. Permanent damage to the equipment can result if directions are not followed exactly as provided. This system is very sensitive to power supply operation and, if not powered up in the proper order, permanent damage may occur. Please read the power up sequence before applying power. Also, provide only the power specified in this document (voltage and frequency). Important Configuration Notes These Subscriber Unit (SU) devices do not require any user interface. After configuring the Hub unit (called Base Station (BS) in this document elsewhere), the CPE devices will automatically negotiate with the Hub if sufficient signal strength is received in both directions to establish communications. The Ethernet Console program is not ultimately intended to be a users interface. However, this program does provide configuration controls for this particular system. The syntax of the data entry must be followed exactly as shown. When a string of characters is shown in this document with quotation marks around it (such as ip), do not type the quotation marks. When the letter x is shown within the quotation marks, this represents a number that the operator will select based on other factors. When the word (enter) is shown, this indicates pressing of the Enter (or Return) key on your keyboard. Wherever there are spaces shown in the syntax of a command, include these spaces. Commands are case sensitive.

Initiate Ethernet Console on your PC by double-clicking on this icon that appears on your PC desktop Ethernet Console e. Connect a straight CAT5 cable between your PC and the BS f. Connect the BSU to the power supply via the cable provided MAKE SURE POWER SWITCH ON THE POWER SUPPLY IS SET TO THE OFF POSITION!

Connect the BSU power cord to 115Vac, 60 Hz power ALL CABLES MUST BE CONNECTED BEFORE POWER IS TURNED ON!

IF NECESSARY, TURN TOGGLE SWITCH TO THE OFF POSITION BEFORE DISCONNECTING CABLE BETWEEN BSU AND POWER SUPPLY Turn power supply on with toggle switch located on the power supply Wait approximately 10 seconds. Watch the Ethernet Console for the initiation screen shown below.

(The upper right corner of the Ethernet Console window changes from Ethernet Console to BSU Console as shown below.) 3-5 T S U N A M I M U L T I P O I N T If BSU Console appears, but wakeup screen is not present type version (return) you should see the screen above. If Ethernet Console does not change to BSU Console after 30 seconds recycle the power using the toggle switch on the power supply. Try several times if needed. Type pa 255 (return) this sets the units output power to on using ALC Type pa (return) to make sure pa command was received screen should show Current_TXDAC= 160 Type pa 0 (return) to turn the transmitter power off. The default IP address of the BSU is 192.168.20.120. To set the units IP address, type ip xxx.xxx.xxx.xxx (return) If necessary, change your PCs IP address to match the new numbering scheme Reinitiate the Ethernet Console program if necessary. After reestablishing communications (if this was necessary), type ip (return) to verify new the new IP address. The default subnet mask of the BSU is 255.255.255.0 (-1.-1.-1.0 in signed integer form). To change the subnet mask of the unit, type netmask xxx.xxx.xxx.xxx (return) This version of software does not provide direct verification of the subnet mask. You may type netmask (return) to view the current subnet mask setting, however the number provided is in degrees format (signed integer equivalent to hexidecimal) instead of hexidecimal or decimal. The default gateway of the BSU is 192.168.20.201. To change the gateway address for the unit, type gateway xxx.xxx.xxx.xxx (return) To verify gateway address for the unit, type gateway (return) The default setting of the BSU for bandwidth modes is QPSK (20 Mbps), also known as modulation mode 3. To change bandwidth mode to QPSK (30 Mbps), type modulation 2 (return) and then type setconf (return) to activate this setting. If you wish to return to QPSK (20 Mbps) mode, type modulation 3 (return) and then type setconf (return). To verify bandwidth (modulation) mo de, type modulation (return) The default setting of the BSU for uplink and downlink time slot allocation is 5 time slots downlink and 3 slots uplink (corresponding to the 20 Mbps bandwidth mode, which has 8 total time slots). To change these settings, type firstInboundSlot x (return) and then type setconf (return). In the 20Mbps bandwidth mode (modulation mode 3), the lowest number for this setting is 2 and the highest is 5. In the 30 Mbps bandwidth mode

(modulation mode 2), the lowest number for this setting is 2 and the highest is 9. To verify the uplink and downlink time slot allocations, type firstInboundSlot (enter) Helpful hint: The number x within the statement firstInboundSlot x is equivalent to the total number of downlink timeslots that are allocated (zero through first inbound slot minus 1). The default setting of the BSU channel frequency is 3. There are four operating channel frequencies in this model. To change the frequency channel of the BS, type frequency x

(return), then type setconf (return). Valid numbers are 0 through 3. 3-6 T S U N A M I M U L T I P O I N T To verify the frequency channel, type frequency (enter). At any time, if you wish to return a unit to the factory default settings, you may type restart (return) or cycle power (using the toggle switch on the power supply). It is advised to use the restart command. 3-7 T S U N A M I M U L T I P O I N T Subscriber Unit Configuration The CPE units require the same software and are connected and controlled in an identical fashion as the BS. Configure the BSU unit and your computer first to become familiar with these connections and controls and to be ready to connect to the CPE. CONNECT ALL CABLES BEFORE PLUGGING INTO AC POWER DISCONNECT AC POWER FIRST BEFORE REMOVING THE CABLE BETWEEN THE POWER SUPPLY AND CPE ONLY THEN APPLY 115VAC 60 Hz POWER When your PC is connected to a CPE unit, the Ethernet Console will display SU Console (instead of BSU Console) in the upper right corner of the screen. Use the IP, gateway and subnet mask commands to change or verify these settings for each CPE unit. No other commands should be needed. The CPE will automatically detect proper operating frequency and bandwidth settings. It can be helpful to configure the CPE equipment before it establishes a link with the BS. When RF communication is initiated, the units will start negotiating and registering IP addresses, setting frequency channels and other settings. The terminal number of the CPE is labeled on the bottom of the CPE, and this number (along with IP address and Ethernet address) will appear on the BSU console screen when the CPE is negotiating with the BSU for initialization. When a link is established, both ends of the system will display different communications on the Console window. The signal strength can be seen on the SU Console, and this can be used as a rough antenna alignment tool. The command to view signal strength is rsl (return). To align antennas, align by sight, type rsl

(return) in the SU console, read the RSL, make fine adjustments to the antenna alignment, and type rsl (return) again, repeating until signal is peaked. The number returned by the rsl command is in dBm, therefore, the less negative the number, the stronger the signal (such as 40 is higher than 50). 3-8 T S U N A M I M U L T I P O I N T Mechanical Considerations Mounting Units The CPE units are designed to directly mount to 1-1/2 inch to 1-3/4 inch pole diameters (outer diameter), or mount to pole diameter of 2 inches or to a wall or other flat surface using optional mounting brackets. For mounting directly to a 1-1/2 inch or 1-3/4 inch pipe, first attach the mounting bracket to the pole using the U-bolt retainer. Then attach the SU to the mounting bracket, and lock into position by tightening the 10-32 screws. See photos below for detail. Connect the weatherproof RJ45 connector. For mounting to a flat surface, attach mounting bracket to the CPE using bolts supplied, and then mount to flat surface using your own hardware.
