Chapter 1 System Description
Chapter 1 - System Description In This Chapter: “Introducing BreezeACCESS 4900” on page 3 “Base Station Equipment” on page 5 “Subscriber Unit” on page 8 “Networking Equipment” on page 12 “Management Systems” on page 13 “Specifications” on page 15 BreezeACCESS 4900 2 System Manual
Chapter 1 - System Description 1.1 Introducing BreezeACCESS 4900 Introducing BreezeACCESS 4900 BreezeACCESS 4900 is a high capacity, IP services oriented Broadband Wireless Access system operating in the 4.9 GHz licensed spectrum band allocated for public safety. The system employs wireless packet switched data technology to support high-speed IP services including fast Internet and Virtual Private Networks.
Chapter 1 - System Description Introducing BreezeACCESS 4900 environments. These qualities enable service providers to reach a previously inaccessible and broader segment of the subscriber population. A BreezeACCESS 4900 system comprises the following: Customer Premise Equipment (CPE): BreezeACCESS 4900 Subscriber Units (SUs). Base Station Equipment (BS): BreezeACCESS 4900 Access Units and supporting equipment.
Chapter 1 - System Description 1.2 Base Station Equipment Base Station Equipment The Access Units, installed at the Base Station site, provide all the functionality necessary to communicate with the Subscriber Units and to connect to the backbone of the Service Providers. There are 2 lines of Access Units with different architectures: Modular Base Station Equipment Standalone "Micro-Cell" Access Unit 1.2.
Chapter 1 - System Description Base Station Equipment BreezeACCESS 4900 Access Units, and a different power supply module, suitable for GFSK equipment, is required for powering the BreezeACCESS GFSK Access Units. Each BS-AU module and its outdoor radio unit (AU-ODU) comprise an AU E-BS Access Unit that together with an external antenna serve a single sector/cell.
Chapter 1 - System Description Base Station Equipment the outdoor unit via a Category 5E Ethernet cable. This cable carries Ethernet traffic between the indoor module and the outdoor unit, and also transfers power (54 VDC) and control from the indoor module to the outdoor unit. 1.2.2 Standalone "Micro-cell" Access Unit Figure 1-3: Standalone AU-E-SA Access Unit The standalone AU-E-SA Access Unit is very similar to the AU-E-BS unit.
Chapter 1 - System Description 1.3 Subscriber Unit Subscriber Unit The Subscriber Unit (SU) installed at the customer premises enables the customer data connection to the Access Unit. The Subscriber Unit provides an efficient platform for high speed Internet and Intranet services. The use of packet switching technology provides the user with a connection to the network that is always on, enabling immediate access to services.
Chapter 1 - System Description 1.4 DC Power Injector DC Power Injector The DC Power Injector is an indoor unit designed for sites in which protected DC sources are available (48 to 55 VDC), such as many of the GSM sites. This allows operators to utilize their existing protected backup DC systems to feed the VL outdoor units.
Chapter 1 - System Description DC Power Injector The DC Power Injector has two RJ45 jacks at one end (see Figure 1-4): WAN/Eth: For connection to the network DC IN: For connection to the DC power source via the supplied cable (see Figure 1-5) The other end has another RJ45 jack for connecting to the outdoor unit via an Ethernet cable CAUTION When using the injector, the following restrictions apply: The DC Power Injector does not include surge protection for either the DC or Ethernet input.
Chapter 1 - System Description 1.5 BreezeACCESS VL B&B (4.9 GHz only) BreezeACCESS VL B&B (4.9 GHz only) BreezeACCESS VL B&B is available to support point-to-point applications. A B&B point-to-point link includes: AU-D-SA-4.9-6-VL: A standalone AU with a 25 dBi, 6° high gain directional antenna. SU-D-4.9-54-BD-VL: SU-54-BD with a 25 dBi, 6° high gain directional antenna.
Chapter 1 - System Description 1.6 Networking Equipment Networking Equipment The Base Station equipment is connected to the backbone through standard data communication and telecommunication equipment. The 10/100BaseT ports of the AU modules can be connected directly to a multi-port router or to an Ethernet switch connected to a router. The point-to-point link from the Base Station to the backbone can be either wired or wireless. Data to the Internet is routed to the backbone through standard routers.
Chapter 1 - System Description 1.7 Management Systems Management Systems The end-to-end IP-based architecture of the system enables full management of all components, from any point in the system. BreezeACCESS 4900 components can be managed using standard management tools through SNMP agents that implement standard and proprietary MIBs for remote setting of operational modes and parameters.
Chapter 1 - System Description Management Systems designed for today's most advanced Service Provider Network Operation Centers (NOCs), providing the network Operation, Administration and Maintenance (OA&M) staff and managers with all the network surveillance, monitoring and configuration capabilities that they require in order to effectively manage the BWA network while keeping the resources and expenses at a minimum.

Chapter 2 - Installation 2.2 Equipment Positioning Guidelines Equipment Positioning Guidelines This section provides key guidelines for selecting the optimal installation locations for the various BreezeACCESS 4900 system components. CAUTION ONLY experienced installation professionals who are familiar with local building and safety codes and, wherever applicable, are licensed by the appropriate government regulatory authorities should install outdoor units and antennas.
Chapter 2 - Installation Equipment Positioning Guidelines signals strength. As a rule of thumb, if the SU is located at a distance of less than 300 meters from the Base Station, it is recommended to up-tilt the antenna by approximately 10° to 15° (especially in line-of-sight conditions) to avoid saturation of the receivers by too strong signals. The indoor equipment should be installed as close as possible to the location where the indoor-to-outdoor cable enters the building.
Chapter 2 - Installation 2.3 Installing the Outdoor Unit Installing the Outdoor Unit The following sections describe how to install the outdoor units, including pole mounting the ODU, and connecting the indoor-to-outdoor, grounding and RF cables NOTE Ensure that outdoor units, antennas and supporting structures are properly installed to eliminate any physical hazard to either people or property.

All other packets will be routed to the Low queue (unless they were assigned a High priority by another classifier).
Chapter 4 - Operation and Administration Menus and Parameters Delete UDP Port Ranges: This option enables deleting UDP port ranges from the list of priority port numbers. It is possible to delete discrete port numbers and/or ranges. In ranges, a hyphen is used to separate between start and end port numbers. A comma is used to separate between entries.
