1-2 BreezeNET DS.11 Series User’s Guide Scope of the Guide This User's Manual provides instructions for planning and setting up a wireless link based on the BreezeNET DS.11 wireless Base Unit and Remote Bridge. ♦ Chapter 1: Introduction - Describes how to use this manual and presents the BreezeNET DS.11 series. ♦ Chapter 2: Installation - Describes how to install the BreezeNET DS.11 units. ♦ Chapter 3: The DS.11 Configuration Utility - Describes how to use the DS.
Introduction 1-3 System Description The BreezeNET DS.11 wireless Base Unit (BU-DS.11) and Remote Bridge (RB-DS.11) are designed to provide longrange point-to-multipoint links for outdoor applications. The products use direct sequence spread spectrum radio technology operating at the frequency range of 2.4 – 2.4835 GHz, a part of the FCC's unlicensed Industrial, Scientific and Medical (ISM) band. Data is transmitted at rates of up to 11 Mbps, providing network users with full 10BaseT Ethernet speeds.
BreezeNET DS.11 Series User’s Guide 1-4 BU-DS.11 Wireless Base Unit The BU-DS.11 is an IEEE 802.11b compliant base station that connects one or more remote sites to a central server or Internet connection. In a point-to-multi-point configuration the BU-DS.11 is the central unit while in point-to-point configurations it should be installed at one end of the link. The BU-DS.11 is available in two options: The BU-DS.11 and the BU-DS.11D. The BU-DS.
Introduction 1-5 When a station on the Ethernet LAN sends a message that is not destined for a local station, the RB-DS.11 forwards the message to the BU-DS.11. When the BU-DS.11 receives a message destined for a station on the RB-DS.11's LAN, the BU-DS.11 forwards it to the RB-DS.11. In this manner, the RB-DS.11 and the BU-DS.11 work together like a standard network bridge. The first time each station on the RB-DS.11’s LAN sends a message, the station’s address is registered by both the RBDS.
BreezeNET DS.11 Series User’s Guide 1-6 BreezeNET DS.11 Compatibility and Standards BreezeNET DS.11 products are compatible with the following standards and are interoperable with other IEEE 802.11b compatible, 2.4 GHz direct sequence products. ♦ IEEE 802.11b Wireless LAN. ♦ IEEE 802.3 10BaseT Ethernet. ♦ DHCP for automatic IP address assignment. ♦ SNMP for system management.

2-6 BreezeNET DS.11 Series User’s Guide Outdoor Installation Considerations This section describes various considerations to take into account when planning an outdoor installation including site selection, antenna alignment, antenna polarization, antenna seal, and cell size. Collocating DS.11 Outdoor Units Up to three BU-DS.
Installation 2-7 Path of Clearest Propagation A propagation path is the path that signals traverse between the antennas of any two units. The “line” between two antenna sites is an imaginary straight line, which may be drawn between the two antennas. Any obstacles in the path of the “line” degrade the propagation path. The best propagation path is, therefore, a clear line of sight with good clearance between the “line” and any physical obstacle.
BreezeNET DS.11 Series User’s Guide 2-8 ♦ Antenna Height: Path loss is lower when antennas are positioned higher. Antenna height is the distance from the imaginary line connecting the antennas at the two sites to ground level. Ground level in an open area is the actual ground. In dense urban areas, ground level is the average height of the buildings between the antenna sites. Rooftop Installation Rooftop installations offer several advantages: ♦ Fewer obstacles in the path.
Installation 2-9 Point-to-Multipoint Setting up a point-to-multipoint link requires the use of a Base Unit equipped with an omni-directional antenna (or an antenna with sufficient bandwidth to illuminate all units) and at least two remote units equipped with high-gain directional antennas. Antenna Polarization Antenna polarization must be the same at both ends of the link. In most applications, the preferred orientation is vertical polarization, which is best for above ground propagation.
BreezeNET DS.11 Series User’s Guide 2-10 NOTE: The maximum distance of 24Km/15 miles is achieved using 24 dBi antennas and 24 dBm output power. The maximum distance of 10Km is achieved using 24 dBi antennas and –4dBm output power. Using Outdoor Range Tables Specific range tables, guidelines and information about extended cables can be obtained from your local dealer or the Alvarion central offices. Outdoor installations must have a clear line-of-sight between antennas.

DS.11 FAQ A-1 Appendix A The appendix provides answers to the most commonly asked questions concerning the DS.11 system. The appendix is divided into the following categories: ♦ General, page A-2. ♦ Collocation, page A-5. ♦ Performance, page A-7. ♦ Firmware, page A-8. ♦ Configuration, page A-10. ♦ Accessories, page A-11. ♦ Management, page A-12.
BreezeNET DS.11 Series User’s Guide A-2 General Can the BU-DS.11/RB-DS.11D indoor unit be placed outdoors? It is not recommended. The BU-DS.11/RB-DS.11 indoor units are specified to operate between 0°C and 40°C and is not weather proof so it is best to mount the DS.11 indoors or in a protective cabinet. Do DS.11 units support 802.1Q VLAN? Yes, but the support is limited to transparent operation. This means that the DS.11 does not take any action on 802.
DS.11 FAQ A-3 What is the practical limit to the number of RB-DS.11 units per BU-DS.11? And, what performance can I expect for a multi-point link? This depends upon average throughput expectations. All clients would have the maximum throughput available for burst traffic, however the overall average would depend on the utilization of the network. For example, in a heavily utilized network needing about 350Kbps to 500kbps average net throughput per site, 9 to 12 RB-DS.11’s would be the limit.
BreezeNET DS.11 Series User’s Guide A-4 What is the normal PER (Packet Error Rate) for the BUDS.11/RB-DS.11? The error rate will be about 4%-6% (transmitted fragments vs. retry count). This is typical when operating in a non-interference environment at maximum range for bi-directional traffic loads. If the traffic load is more uni-directional, then the PER will be less. What is the best value for the CW min parameter on the DS.
DS.11 FAQ A-5 Collocation How many BU-DS.11 or RB-DS.11 units can be collocated on the same building or tower? You can collocate up to 3 BU-DS.11 or RB-DS.11 units on the same structure. Each unit is assigned to one of the nonoverlapping channels, 1, 6, or 11. What is the antenna separation requirement for collocating BU-DS.11 or RB-DS.
A-6 BreezeNET DS.11 Series User’s Guide Can I use DS.11 Bridges to feed a Frequency Hopping distribution point? Yes, bandwidth sharing between the Direct Sequence and Frequency Hopping products can be minimized if the network is designed using cross-polarized directional antennas with as much spatial separation as possible. Contact technical support for more information.
DS.11 FAQ A-7 Performance What is the throughput of the DS.11? The BU-DS.11/RB-DS.11 bridge link typical performance is 4.2Mbps using TCP and 6.2Mbps using UDP. For long-range links, the performance drops by about 5%. What if the DS.11 link experiences interference? If interference is affecting the DS.11 link, one of the other channels may be selected to operate away from the frequency of the interference. Also, physically re-locating the antennas may help. What is the typical latency of a BU-DS.11/RB-DS.
BreezeNET DS.11 Series User’s Guide A-8 Firmware Can the BU-DS.11/RB-DS.11 firmware be upgraded? Yes, the firmware in the BU-DS.11/RB-DS.11 is stored in flash and is upgraded using the built in Configuration Utility or the TFTP server. Can the BU-DS.11/RB-DS.11 flash be erased or the firmware changed by an unauthorized person? No, the TFTP server in the BU-DS.11/RB-DS.11 requires the SNMP write community name (password) to perform an upgrade.
DS.11 FAQ A-9 Can the previous version of firmware be kept? The previous version of firmware cannot be kept on the DS.11 itself, but can be stored on your PC and loaded if needed.
BreezeNET DS.11 Series User’s Guide A-10 Configuration Can the regulatory domain (country) of a DS.11 unit be changed? No. The regulatory domain is factory set. How can the DS.11 be configured or managed if the SNMP Community name has been forgotten? Press the reset button on the top panel with a paper clip. This will set the read and write Community names to public and private, respectively. How can the DS.11 unit be returned to factory default settings? There are two ways.
DS.11 FAQ A-11 Accessories Can I use the same accessories on my BreezeNET DS.11 as on my BreezeNET PRO.11? Not all BreezeNET PRO.11 accessories are compatible with the DS.11. For example, the TPA (Transmit Power Amplifier), LNA (Low Noise Receive Amplifier) and AMP 250/500 (BiDirectional Amplifier), which are all compatible with the BreezeNET PRO.11, cannot be used with the DS.11. Can the BreezeNET PI-CAT5 product be used with a DS.11 unit? No. The PI-CAT5 is specifically for the BreezeNET PRO.
BreezeNET DS.11 Series User’s Guide A-12 Management What management options are available for the DS.11? The BU-DS.11/RB-DS.11D comes with a graphical Configuration Utility that operates on any Windows based network ready PC. With this utility you can configure and monitor every DS.11 on your network. You can also use the DS.11 SNMP MIB on standard management platforms like SNMPc, and HP Openview. Does the DS.11 offer out-of-band management? No, the DS.

Radio Signal Propagation C-1 Appendix C This section explains and simplifies many of the terms relating to antennas and RF (Radio Frequency) used when dealing with an RF installation system. The following diagram depicts a typical radio system: Figure C-1: A Typical Radio System A radio system transmits information to the transmitter. The information is transmitted through an antenna that converts the RF signal into an electromagnetic wave.
BreezeNET DS.11 Series User’s Guide C-2 The electromagnetic wave is intercepted by the receiving antenna, which converts it back to an RF signal. Ideally, this RF signal is the same as that originally generated by the transmitter. The original information is then demodulated back to its original form. RF Terms and Definitions dB The dB convention is an abbreviation for decibels. It shows the relationship between two values.
Radio Signal Propagation C-3 Figure C-2: Attenuation of an RF signal Pin is the incident power level before attenuation Pout is the output power level after attenuation Attenuation is expressed in dB as follows: PdB = -10 x Log (Pout/Pin) For example: If, due to attenuation, half the power is lost (Pout/Pin = 1/2), attenuation in dB is -10 x Log (1/2) = 3dB Path Loss Loss of power of an RF signal traveling (propagating) through space. It is expressed in dB.
BreezeNET DS.11 Series User’s Guide C-4 R is the distance between the transmitting and receiving antennas (expressed in Km). At 2.4 GHz, this formula is: 100+20xLog(RKm) Antenna Characteristics Isotropic Antenna A hypothetical antenna having equal radiation intensity in all directions. Used as a zero dB gain reference in directivity calculation (gain). Antenna Gain A measure of directivity.
Radio Signal Propagation C-5 Omni-directional Antenna Radiates and receives equally in all directions in azimuth. The following diagram shows the radiation pattern of an omni-directional antenna with its side lobes in polar form. Figure C-3: Radiation Pattern of an Omni Antenna - Side View Figure C-4: Radiation Pattern of an Omni Antenna - Top View Directional Antenna Radiates and receives most of the signal power in one direction.
BreezeNET DS.11 Series User’s Guide C-6 Figure C-5: Radiation Pattern of Directional Antenna Antenna Beamwidth The directiveness of a directional antenna. Defined as the angle between two half-power (-3 dB) points on either side of the main lobe of radiation. System Characteristics Receiver Sensitivity The minimum RF signal power level required at the input of a receiver for certain performance (e.g. BER). EIRP (Effective Isotropic Radiated Power) The antenna transmitted power.
Radio Signal Propagation C-7 Pl - Path loss in dB Cr - Receiver cable attenuation in dB Si - Received power level at receiver input in dBm Ps - Receiver sensitivity in dBm Si = Pout - Ct + Gt - Pl + Gr - Cr EIRP = Pout - Ct + Gt Link Parameters Frequency: 2.4 GHz Pout = 4 dBm (2.5 mW) Tx and Rx cable length (Ct and Cr) = 10 m. cable type RG214 (0.
BreezeNET DS.11 Series User’s Guide C-8 Signal Fading Fading of the RF signal is caused by several factors: ♦ Multipath The transmitted signal arrives at the receiver from different directions, with different path lengths, attenuation and delays. The summed signal at the receiver may result in an attenuated signal. Figure C-6: Multipath Reception ♦ Bad Line of Sight An optical line of sight exists if an imaginary straight line can connect the antennas on either side of the link.
Radio Signal Propagation C-9 ♦ Interference Interference may be caused by another system on the same frequency range, external noise, or some other co-located system. The Line of Sight Concept An optical line of sight exists if an imaginary straight line can be drawn connecting the antennas on either side of the link. Clear Line of Sight A clear line of sight exists when no physical objects obstruct viewing one antenna from the location of the other antenna.
BreezeNET DS.11 Series User’s Guide C-10 R = ½ √ xD R: radius of the first Fresnel zone. λ: wavelength (expressed in feet). D: distance between sites (expressed in Km). Figure C-8: Fresnel Zone Clear of Obstacles When at least 80% of the first Fresnel Zone is clear of obstacles, propagation loss is equivalent to that of free space.
