    Introduction 1. INTRODUCTION 1.1 General This chapter describes the scope of this manual and the main features of the BreezeNET BU-DS.11 (Wireless Base Station) and RB-DS.11 (Wireless Bridge Client). Also in this chapter: relevant standards, compatibility issues, product functionality and use of the DS (Direct Sequence) WLAN.

  • Page 10: Breezenet Ds.11 Functional Description

    Introduction 1.3 BreezeNET DS.11 Functional Description The BreezeNET BU-DS.11 and RB-DS.11 can be used as a high speed connection between two remote networks. Server Server Figure 1-1. DS.11 Outdoor Application BU-DS.11 Wireless Base Station The BU-DS.11 is an IEEE 802.11 TGb-compliant base station bridge that is used to connect either a single remote site or multiple remote sites to a central server or Internet connection.
  • Page 11 Introduction The RB-DS.11 comes in two options: the basic unit comes with an antenna integrated on the front cover of the Outdoor unit. The RB-DS.11D has no integral antenna, and provides two antenna connectors (on the Outdoor unit) for connection of one or two external antennas. Refer to Section Sections 2.6.4 and 2.6.12 for information on how to select external antennas.

  • Page 13: Installation

    Installation 2. INSTALLATION 2.1 Quick Start to Wireless Networking Perform the following steps to configure a WLAN for the first time: 1. Physically connect the BU-DS.11/RB-DS.11 units to the Ethernet LAN. Make sure they are switched on. The DS.11 wireless network will be up and running immediately. If you are content with the default settings of the BU-DS.11/RB-DS.11 units, you can stop right here.

  • Page 14: Packing List

    BreezeCOM and its resellers or distributors are not liable for injury, damage or violation of regulations associated with the installation of outdoor units or antennas.
  • Page 15 Installation 2. Mount the Outdoor unit and the external antennas (optional). Connect the Outdoor unit to the antenna if installing external antennas. Note: The FCC 15.203 requirement prohibits the connection of external antennas with standard N- type connectors. In order to meet this requirement, the external antenna connectors provided on DS.11D models (with no integral antenna) are non-standard, featuring left-handed (counter- clockwise) rotation.

  • Page 17: Guidelines For Placement Of Bu-Ds.11 Units

    Installation 2.5 Guidelines for Placement of BU-DS.11 Units Each Wireless Base Station in the network forms the center of a cell, or BSS. The placement of BU-DS.11 units should be such that cells overlap slightly, to guarantee seamless wireless connectivity everywhere. Neighboring BU-DS.11 units should preferably send and receive on different channels for maximum throughput.

  • Page 18: Outdoor Installation Considerations

    Installation 2.6 Outdoor Installation Considerations This chapter describes various considerations to take into account when planning an outdoor installation including site selection, antenna alignment, antenna polarization, antenna seal, and cell size. 2.6.1 Co-locating DS.11 Outdoor Units Up to 3 BU-DS.11 or RB-DS.11 units can be co-located on the same building top or tower. Each unit is assigned to one of the non-overlapping channels, 1, 6, or 11.
  • Page 19 Installation Minimal Path Loss Path loss is determined mainly by several factors: •4 Distance between sites – Path loss is lower and system performance better when distances between sites are shorter. •5 Clearance – Path loss is minimized when there exists a clear line of sight. The number, location, size, and makeup of obstacles determine their contribution to path loss.

  • Page 20: Rooftop Installation

    •3 Improved performance due to greater height. •4 Reduced multipath problems. 2.6.4 Antennas for Outdoor Applications BreezeNET DS.11 series can be used in point-to-point or point-to-multipoint configurations. Point-to-Point The BU-DS.11/RB-DS.11 must be equipped with one or two directional antennas. The necessary antenna gain depends on the required range and performance.

  • Page 21: Antenna Diversity

    In applications where no multipath propagation is expected, a single antenna is sufficient for good performance levels. However, in cases where multipath propagation exists BreezeCOM recommends using two antennas in order to utilize the space diversity feature. By using two antennas per unit, the system can select the best antenna on a per-packet basis (every several milliseconds).

    Extending coaxial cables can cause an increase in assembly signal loss and a reduction in range. Specific range tables, guidelines and information about extending cables can be obtained from your local dealer or the BreezeCOM central offices. 2.6.12 Available Antennas and Antenna Kits Table 2-2 and Table 2-3 list several transmit/receive antennas that work well with BreezeNET DS.11...

Used as a zero dB gain reference in directivity calculation (gain). Antenna Gain A measure of directivity. It is defined as the ratio of the radiation intensity in a given direction to the radiation intensity that would be obtained if the power accepted by the antenna was radiated equally in all directions (isotropically).

EIRP (Effective Isotropic Radiated Power) The antenna transmitted power. Equal to the transmitted output power minus cable loss plus the transmitting antenna gain.

  • Page 63: Figure A-6. Multipath Reception

    Appendix A. Radio Signal Propagation In conclusion, the received signal power is above the sensitivity threshold, so the link should work. The problem is that there is only a 2 dB difference between received signal power and sensitivity. Normally, a higher margin is desirable due to fluctuation in received power as a result of signal fading.

    Appendix C. DS.11 FAQ APPENDIX C. DS.11 FAQ How many BU-DS.11 or RB-DS.11 units can be co-located on the same building top or tower? You can co-locate up to 3 BU-DS.11 or RB-DS.11 units on the same structure. Each unit is assigned to one of the non-overlapping channels, 1, 6, or 11.
  • Page 70 Appendix C. DS.11 FAQ Why are there 11 channels and only 3 usable? The IEEE802.11 specification calls out 11 selectable channels (USA) between 2414MHz and 2462MHz. Because of the transmission bandwidth of the DS modulation, only 3 channels are non- overlapping.
  • Page 71 Appendix C. DS.11 FAQ Can I downgrade my DS.11 firmware? Yes, an earlier version of firmware can overwrite a newer version. Can I keep the previous version of firmware? No and yes. The previous version of firmware can not be kept on the DS.11 itself, but can be stored on your PC and loaded if needed. Does DS.11 support 802.1Q VLAN? Yes, but the support is limited to transparent operation.
  • Page 72 Appendix C. DS.11 FAQ What is the maximum number of networked PC’s the BU-DS.11/RB-DS.11 can learn? 1024 network MAC addresses can be learned by the BU-DS.11/RB-DS.11. Can the BU-DS.11/RB-DS.11 be used for multi-point as well as point to point links? Yes.
  • Page 73 Appendix C. DS.11 FAQ The DS.11 comes with a Windows based manager utility. With this utility you can configure link parameters and monitor signal quality and RSSI (received signal strength indication). Optimizing antenna alignment is done using the signal quality and RSSI display. Any computer on the network can use this utility to manage the BU-DS.11/RB-DS.11.
