Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios Pre-installation Tasks This section describes the steps necessary to prepare a site for the installation of the Exalt Digital Microwave Radio. Link Engineering and Site Planning Design all terrestrial wireless links prior to purchase and installation.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios The two radio terminals are identical hardware, except for the TDD setting in software. When the radios are in their default state, both radios are configured as Radio B. One end of the link must be configured as Radio A before the two ends of the radio system can communicate. It can be considered that Radio A is the primary radio in the link. Radio A provides the master clock and control to Radio B.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios Initial Configuration and Back-to-Back Bench Test Every Exalt digital microwave radio goes through extensive quality testing and performance evaluation over the full operating temperature range prior to shipment. However, before installation, it is strongly advised to perform several tests and tasks that are much more difficult to perform once the radio link endpoints are distant from one another.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios – Confirm unfaded error-free performance Some of these tasks may not be possible or practical within a bench test environment due to the nature of the remote connectivity of peripheral equipment. However, it is good practice to perform as much as possible in this environment to minimize field/installation time and troubleshooting efforts.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios Use the ExaltCalc calculator to determine optimum settings for the above parameters to meet the needs of your application.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios Note: It is not always necessary to synchronize collocated radios. If antennas are substantially separated or blocked from one another and/or frequency separation tuning is used, the opportunity for near-end interference can be eliminated. Note: When synchronization is required or desired, one GPS kit per link is required.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios Note: In many cases, the system design will not be identical to the factory default configuration, and in some cases, these differences prohibit the installation of the radio. If at all possible, obtain a computer and configure the radio terminals using the browser-based GUI. See Exalt Graphical User Interface (GUI) for details. Radio Reset Use the reset function if the IP address and/or passwords are lost.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios • Mode – It is desirable, but not always necessary, to match the mode for all collocated links. • Bandwidth – It is desirable, but not always necessary, to match the bandwidth for all collocated links. For complex networks, an Exalt engineer should review multi-link networks before deployment as several factors can optimize the network for desired performance.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios synchronized to any source. If the original sync source is restored to the flywheeling radio’s configuration, it attempts to synchronize to this signal without causing transmission interruption.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios Note: Asymmetry is only supported for a specific subset of system configurations that are optimized for typical asymmetric applications. TDD frame sizes of 2ms and 5ms are supported. The 5ms configuration maximizes the aggregate throughput of the radio for every situation. The 2ms configuration reduces latency to meet latencycritical applications, especially for multi-link and TDM circuit support.
Exalt Installation and Management Guide ExtendAir (TDD) Series Digital Microwave Radios One feature of the SNMP implementation is that system configuration changes do not take effect using the SET command. Instead, groups of configuration settings can be preconfigured for global change, and a single ‘Save’ (Commit) command implements all changes. When some parameters are changed, a link may drop and/or management control lost.
