MDR5800 User Manual862-01881 Issue 6 Page 203 PLANNINGThis chapter is aimed at management and planning staff to enable them to assess therequirements for installing an MDR5800 digital radio link.3.1 System Type SelectionThe MDR5800 system uses an Outdoor Unit with a type-N RF output for connectionto a range of antennas.The MDR5800 is aimed at FCC regulated markets.Antenna polarisation can used to co-locate multiple MDR5800 systems.Antenna polarisation can be used to overcome interference.3.1.1 Antenna selection (MDR5800)The antenna type must be selected before the MDR5800 system is to be installed.The chosen antenna must enable the system to operate with sufficient link fademargin without excessive cost and allow the user’s ‘link availability requirements’ tobe met.The main consideration when selecting an antenna is antenna gain measured in dBi.A path loss analysis is highly recommended to determine the antenna gain needed foradequate fade margin. The table below shows antenna selection guidelines for someconfigurations. The distances are calculated for a 20 dB link fade margin.Table 3 MDR25800 Antenna SelectionAntenna Type Gain(dBi) Distance (Km) Power level(dBm)0.15 m Flat panel 18 9 240.3 m Flat panel 24 30 240.6 m Flat panel 28 80 24

MDR5800 User Manual862-01881 Issue 6 Page 213.2 Site EvaluationWhen planning a site for a digital radio link, it is of the utmost importance that youtake the operational environment of the proposed site into account.The combined effect of atmospheric environmental factors such as rain and lightning,atmospheric attenuation, signal path obstruction, propagation fading, air temperaturegradients, ice build-up, wind and solar radiation can contribute towards reducing thelevel of performance of the system. In the higher frequency bands, rainfall is themain attenuation mechanism that limits error performance. Ice and snow will have asimilar effect. Severely cold and excessively warm climatic conditions outside thescope of the operating temperature range can affect the function of the system,especially the outdoor equipment (see Environmental Characteristics on page 64 ofthis manual).Also, if masts are not sufficiently rigid, very strong winds can affect the antenna beamalignment and Outdoor equipment reliability due to wind force build-up and/orvibration of the mast-mounted equipment.3.3 Multipath EffectsThe MDR5800 digital radio operates at frequencies close to 5.8 GHz and can beinfluenced by the effects of multipath propagation. Understanding these effects willhelp when installing an MDR5800 digital radio link and maximise the reliability of thelink.Multipath fading occurs when the receiving antenna receives not only the direct signalfrom the transmitting antenna but also a signal from the transmitting antenna that hasreflected off the ground or nearby obstacles. The reflected signal takes a longer pathto reach the receiver and acts as interference since it is not in-phase with the directpath signal. The amplitude of the interference can be almost equal to that of thedirect path signal, thus degrading the performance of the link.Multipath propagation is dependent on transmit frequency and the specific geometryof the link such as antenna heights, distance between the antennas and the localterrain. To counteract multipath propagation, the installer can change the frequencyat which the link operates or adjust the height of one or both of the antennas.Figure 4.

MDR5800 User Manual862-01881 Issue 6 Page 223.4 Interference ConsiderationsThe ISM frequency bands are used by devices that can cause interference to theMDR5800 radio system. Interference can be avoided by careful planning of thesystem installation. The available methods for providing isolation from interferingradiators are the following:• Frequency diversity• Antenna polarisationIt is recommended to scan the proposed installation areas (spectrum analyzer) toestablish the presence of interference. The frequency spectrum should be scannedover a sufficient time period to ensure that periodic transmissions are recorded.Interferers will cause problems if their amplitudes are not more than 20 dB below theintended receive power level. A link path loss calculation should be performed todetermine the expected receive power level.The procedure for selecting the optimum antenna polarisation and system frequencyplan is the following:• Perform a spectral analysis at each site in the link direction using a high gainantenna.• Repeat the spectral analysis for vertical and horizontal polarisation.• Select the polarisation with the lowest interfering levels as the system antennapolarisation.• Consult the MDR5800 frequency channel plan as shown in section 2.2.1 andselect the frequency plan that would operate in an interference-free band. Givepreference to channel plans A, B and C as these are optimised for best receiversensitivity.• Install the ‘High Band’ and ‘Low Band’ Outdoor Units at the sites where theywould experience the lowest interference in their respective receive bands.

MDR5800 User Manual862-01881 Issue 6 Page 233.5 Microcell Backhaul Applications of MDR5800 Digital RadiosIn applications where more than one independent and separate links, need to radiate from acentral site, a number of parameters can be taken advantage of, to provide isolation and minimiseinterference between these links:• Frequency multiplexing• Antenna polarisation• Choice of High Antenna GainIt is important to note that these methods only provide isolation between two radio Systems, andthat power levels in the separate systems should be balanced to ensure correct operation.3.5.1 Setting the Transmitted Power LevelsTo minimise interference, received power levels should be balanced between separate radio links.This means that transmit power levels should be set to provide similar levels of received power, asindicated by the RSSI values of the adjacent receivers at the central site.3.5.2 Frequency MultiplexingThe MDR5800 offers four frequency channel plans. A radio link requires two channels (one fortransmit and one to receive) to provide full duplex operation. Each radio has a high and a low sub-band, one that it uses for transmission and another for reception. Terminology definition: the‘High-band Outdoor Unit’ of a system transmits on the higher of the two sub-bands. The ‘Low-bandOutdoor Unit’ of a system transmits on the lower of the two sub-bands. A system (link) always hasone High Band and one Low Band Outdoor Unit. It is important to note that unwanted transmittedsignals in adjacent frequency bands can affect other receivers operating in an adjacent band ifinsufficient antenna isolation is provided. A solution is to group high-band or low-band OutdoorUnits at the central site, rather than group high and low-band Outdoor Units together.3.5.3 Antenna IsolationSeparate links at a central site will have sufficient isolation when radio systems operate outside theradiation beamwidth or side lobes of the system antenna. The achievable isolation can beestablished by examining the measured radiation patterns of the system antennas. Directionalisolation can be used if the antenna radiation is 15 dB or lower relative to the adjacent main beam.Antennas with high directionality will allow reduced angular separation of adjacent systems.Antenna cross-polarisation isolation can be used for adjacent radio links, radiating in the samedirection. Typical isolation of 30 dB can be achieved using high quality antennas.

Thesetup is done with a PC running the supplied NMS software. See chapter 6 for detailson using the NMS software.5.1 Installation Equipment RequiredThe following tools and instruments are required for software setup and aligning theantenna:• RSSI test cable• Voltmeter• Spanner (see appropriate details in installation chapter depending on theantenna being used)• PC with NMS software and supplied serial data cable.• Binoculars (optional) used for locating the far end site. This will assist in theantenna alignment operation.• GPS or Standard Compass (optional) used for locating the far end site. Thiswill assist in the antenna alignment operation.• Bit Error Rate Tester and connecting leads.5.2 Information RequiredYou should know:• the proposed frequency channel plan for each station.• the expected receive level based on the chosen system configuration and apathloss analysis.5.3 Antenna Alignment5.3.1 IntroductionThe MDR5800 should be installed on both sites before alignment starts. Perform thefollowing steps at both stations:1. Switch the Indoor Unit power ON.2. Install and run the MDR5800 NMS Software application.3. Configure the radio channel plan as required.4. Set the transmitted power to maximum.5. Perform a RF loopback test at each site before starting the alignmentprocedure.

MDR5800 User Manual862-01881 Issue 6 Page 375.3.2 Alignment Procedure1. Locate the far site and point the antenna to the antenna at the far site, asaccurately as possible using binoculars or a compass.2. Connect the multimeter to the RSSI connector on the Outdoor Unit using thesupplied RSSI test cable and set the multimeter to measure volts.3. Check the RSSI level and refer to the figure below for received power level.4. Align the antenna until the maximum RSSI is attained.5. Secure the antenna.6. Measure the RSSI level and record the value (see section 5.7).7. Compare with the value with that calculated for the link i.e. using the pathlosscalculation done when planning the link.Figure 5. RSSI as a function of RF input levelThe front panel RF Link LED, the Received Signal Strength Indicators (RSSI : onNMS, via SNMP or as an Electrical signal on the Outdoor Unit), Carrier-detect (NMS,SNMP) and Frame Lock (NMS, SNMP) indicators are available to assist with linkinstallation and alignment.5.3.3 Set Transmitted Power LevelIt is good practice to match received power levels by adjusting transmitted powers ifco-located systems are being installed. This is important to avoid interferencebetween co-located systems. An attenuator can be fitted between the Outdoor Unitand the antenna if the power level cannot be sufficiently reduced. The dBm output atthe OU N-type connector (socket) levels are set via the NMS or using a SNMPManagement application.

MDR5800 User Manual862-01881 Issue 6 Page 8710 APPENDIX B: MANAGEMENT OF THE MDR5800All management of the MDR product is implemented using SNMP (Simple Network ManagementProtocol), an open standard. The MDR5800 product can be managed by:1. Standard SNMP managers such as HP OpenView or SNMPc i.e. there is Open NetworkManagement compatibility.2. For rapid product installation, the NMS GUI Application (hereafter referred to as the NMS-GA) provides extensive management functions on site and, via the microwave radio link,can be used to access the MDR station on the opposite side of the link. The MDR5800NMS-GA is a software application that runs on a PC workstation such as a laptop ornotebook computer that is connected to an MDR 5800 Indoor Unit (IU) serial port (DB9DTE) or an Ethernet connection (10BaseT DTE) (both accessed via the IU front-panel).10.1 SNMP and the MDR5800Use of SNMP within the product allows remote: configuration, monitoring of performance,notification of alarms and firmware upgrades via an IP-network. Within an IP network supportingrouting of IP data, the radios can be supported from any remote location. The product can beaccessed via the Internet if the necessary gateways are provided. A GSM/PCS modem dial-upcapability provides another remote management option.The MDR Indoor Units have built-in SNMP agents and an extensive MIB (ManagementInformation Base). The MDR5800 product uses SNMP V1 (RFC1155, 1157). The user has accessto an Enterprise MIB (obtainable though customer services) and MIB II (RFC 1213).Access to the MIB via the IU SNMP agent is via Ethernet (10BaseT interface on the product's frontpanel) or PPP (RFC 1661) via the product's serial channel Element Manager port. The use ofSNMP provides flexibility for operators with central equipment monitoring. It providesmanagement access to radio configuration (all data interfaces), interface status and statistics, faultand maintenance information.SNMP security (if enabled) is ensured by using a login and password to give the user administratoror basic user rights (a standard user rights option limits the ability to SET MIB variables).The product has threshold-based alarm generation (there is an extensive SNMP trap list with atrap filter that is adjustable via SNMP). Network access (wired or wireless i.e. GSM/PCS Modem)allows over-the-air remote firmware uploading (FTP) with a load verification (and reversion)capability.

MDR5800 User Manual862-01881 Issue 6 Page 88There are three principle requirements to use SNMP with the MDR5800 Radio Stations.1. A Management Station that runs a SNMP Management Software package that is installedon a networked or stand-alone PC that can be connected to an Indoor Unit either using aserial connection or an Ethernet connection. From the Management station, the agentswithin the MDR Indoor Units can be configured or polled for information.2. Agent: The agent accepts SNMP GET, SET or GET-NEXT commands from theManagement Application software and collects or adjusts information from the IndoorUnit's MIB.3. Management Information Base (MIB): the MIB is a database that is accessed based on theOID (object ID) the SNMP Manager has chosen. The MDR Indoor Unit used an EnterpriseMIB and a standard MIB (MIB II) to store or allow access to information relevant to theMDR Link.

Thefile is not the same file that is used with Version 2.x hardware.Updated RSSI and Power control functionality have been added to Version 2.x hardware andfirmware.Version 2.x firmware has1. FTP upload functionality (needs to be activated via the MIB)2. IP Bridging functionality (half and full duplex – selectable via the MIB)3. Band Plan C4. Refer to the MIB section of this manual and look for the † symbol to see what MIB-relatedfunctionality is in place/activated/planned for Version 2.x + firmware.5. Functional RF Loopback built-in test feature.Version 2.x NMS has1. Ability to allow the user to connect to the Indoor Unit using PPP (via a serial cableinterface to the IU’s front panel Element Manager RS232 port) or via Ethernet (via thefront panel RJ45 connector: 10BaseT).2. Graphical Spectrum Analyzer displayBy default, firmware provided for the Indoor Units does not provide a secure login feature (therebylimiting a user’s ability to ‘set’ MIB variables). Suitably adapted firmware versions (dependent onhardware version) need to be requested from the product manufacturer to allow activation of thisfeature.
