1 Overview

Nokia Siemens Networks FlexiHopper XC Microwave Radio (later referredto as FlexiHopper XC) is a reliable and flexible microwave radio, which canbe used in diverse transmission networks: mobile networks, fixed networksor private networks.

FlexiHopper XC is a member of the Nokia Siemens Networks HopperMicrowave Radio family, and it offers transmission capacities of 2 x 2 Mbit/s, 4 x 2 Mbit/s, 8 x 2 Mbit/s or 16 x 2 Mbit/s in 4-state modulation (QPSK)and 8 x 2 Mbit/s, 16 x 2 Mbit/s or 40 x 2 Mbit/s in 16-state modulation (16-QAM).

FlexiHopper XC has a so-called split-mount architecture; it consists of anoutdoor unit, FlexiHopper XC Outdoor Unit and an indoor unit, NokiaSiemens Networks FlexiHub (later referred to as FlexiHub), whichprovides baseband connectivity and is typically located indoors.

The element management of FlexiHopper XC Outdoor Unit is performedby Nokia Siemens Networks FlexiHub Manager (later referred to asFlexiHub Manager) through the FlexiHub. FlexiHopper XC Outdoor Unithas a consistent network management system interface for NokiaSiemens Networks NetAct (later referred to as NetAct), as with other NokiaSiemens Networks transmission products.

Release 2.2 documentation includes two separate product descriptions:one for FlexiHub and one for FlexiHopper XC Outdoor Unit. Therefore,information regarding FlexiHub can be found in Product Description forNokia Siemens Networks FlexiHub. Note that Product Description forNokia Siemens Networks FlexiHopper XC Outdoor Unit includesreferences to the material contained in the Product Description for NokiaSiemens Networks FlexiHub, and therefore it is advised to have access toboth documents.

Transmission capacity

FlexiHopper XC is available for the 7 GHz, 15 GHz, 18 GHz, 23 GHz, 38GHz and, starting from release 2.2, 13 GHz, frequency bands.



Overview

All frequency bands are available with 4-state modulation (QPSK) and 16-state modulation (16-QAM). 16-QAM has the advantages of a narrowspectrum and good output power efficiency. For more information onavailable transmission capacities and frequency bands, see Transmissioncapacities and frequency bands.

Installation

The FlexiHopper XC Outdoor Unit can be installed on a roof, wall, or pole.The FlexiHopper antenna and FlexiHopper Alignment Unit can be installedon either side of a pole. Normally, no loose parts are needed in theinstallation of the alignment unit and the Outdoor Unit. The Outdoor Unitand the antenna are fitted with guides, which prevent installation inconflicting polarisations.

FlexiHopper XC uses the same FlexiHopper antennas and FlexiHopperAlignment Unit as the rest of FlexiHopper family, which make a possibleupgrade to FlexiHopper XC easy, as no antenna re-alignment is needed.

For more information, see Installing Hardware for Nokia SiemensNetworks FlexiHopper XC.

Management system

FlexiHopper XC Outdoor Unit can be controlled and managed both locallyand remotely through the FlexiHub, using FlexiHub Manager. TheManager features an easy-to-use graphical user interface. One of theimportant Manager features is a Commissioning Wizard that guides youthrough the radio hop commissioning tasks.

In FlexiHopper XC, NetAct can be used to monitor alarms andperformance statistics when the Q1 management interface is used. Whenusing an IP-based management interface, only alarms can be monitored.In the network management system, FlexiHub Manager can be usedremotely only with IP DCN management interfaces for remoteconfiguration management. For more information, see FlexiHub Managerunder FlexiHub management in Product Description for Nokia SiemensNetworks FlexiHub.

Overview



2 Applications

2.1 Network applications

FlexiHopper XC is a high-capacity microwave radio operating inconjunction with a hub solution - FlexiHub. Together they provide anoptimal answer to a wide range of wireless access needs in variousnetwork environments, both in cellular and fixed applications.

FlexiHub and FlexiHopper XC are mainly applied in cellular base stationbackhauling. In addition, they can be used for:

. corporate access applications, and

. providing temporary high-capacity wireless link for voice and/or dataapplications.

For more information about the FlexiHub, see Product Description forNokia Siemens Networks FlexiHub.

2.2 Mobile transport network applications

FlexiHopper XC radios are mainly used in macrocellular sites, often incollocated 2G and 3G base stations. Because of a vast increase in voiceand data traffic in mobile networks, not only higher capacity microwaveradios are demanded, but also outstanding capabilities of the wholebackhauling network to support its growth and frequent changes.

FlexiHub offers higher amount and larger variety of transmission interfacesfor Nokia Siemens Networks Flexi EDGE BTS.

In a typical hub and spoke topology networks, FlexiHub provides flexibilityin network expansion and capacity upgrades. It also significantly reducesthe amount of cabling and installation work at the site.



Applications

FlexiHub provides an efficient solution to small and medium sized hubsites. With FlexiHub it is possible to directly connect up to 11 microwaveradios (Outdoor Units). Connectivity between different radio directions isorganised through the software configuration of a single FlexiHub, eitherlocally or remotely. Centralised management system for remote FlexiHubcommissioning allows significant reduction of the operational costs.

Figure FlexiHub in a mobile transport network shows a typical mobilenetwork where FlexiHub is deployed.

FlexiHopper XC is especially suitable for any radio link where the expectedgrowth in capacity may exceed 16E1, but can also be used for any linkfrom 2E1 to 40E1. FlexiHub together with FlexiHopper XC scales from lowcapacity up to 40E1 equivalent capacity per radio hop. However, it ismainly used in the higher network level, while the FlexiHopper andFlexiHopper Plus microwave radios are used in the lower capacitybranches of the network.

2.3 Site configuration example

Figure Site configuration example 1 shows an example site configuration.In this example the high-capacity microwave radio link towards theaggregation network is implemented with FlexiHopper XC. The lowercapacity downlinks are implemented with FlexiHopper microwave radios.The FlexiHub provides connectivity between different radio directions aswell as connection to the local base station(s). Connection to the basestation is done with 8E1 PIU, or, alternatively, with Sub-2M CCU PIU. Incase of 8E1 PIU, It is possible to choose either symmetric (120 ohm) orasymmetric (75 ohm) cabling.

3 Features

3.1 FlexiHopper XC features overview

The FlexiHopper XC Outdoor Unit supports the following features:

. 3.5, 7, 14, 28 MHz channel spacing,

. QPSK and 16-QAM modulations with Reed-Solomon forward errorcorrection (FEC),

. powerful adaptive transversal equaliser against multipathpropagation,

. received signal level measurement,

. ALCQ (Automatic Level Control with Quality measurement) andATPC (Automatic Transmit Power Control) for monitoring thereceived signal level with the BER of the receiver, in order to adjustthe far-end transmitter output power to adapt to the fadingconditions, and

. 1+1 hot standby (HSB) protection with two FlexiHopper XC OutdoorUnits connected to duplicate indoor PIUs.

It is easy to perform an upgrade from FlexiHopper to FlexiHopper XCOutdoor Unit since no antenna re-alignment is needed. FlexiHopper XCuses the same FlexiHopper Antennas and FlexiHopper Alignment Units asthe rest of the FlexiHopper family.

Channel spacing is not limited to the mentioned above values. It ispossible to adjust channel spacing by incrementally increasing/decreasingthe value with the 10 kHz steps. Depending on the market area, it ispossible to use other channel spacing values, for example 5, 7.5, 13.75and 27.5 MHz at 18 GHz. For more information, see Technicalspecifications.



Features

3.2 Transmission capacities and frequency bands

Each FlexiHopper XC 2.2 Outdoor Unit can support up to 40E1transmission capacity. The capacity allowed for a specific Outdoor Unit isdefined by the factory-installed SW licences and the FlexiHub XC MainUnit variant.

FlexiHopper XC is available for the 7 GHz, 13 GHz, 15 GHz, 18 GHz, 23GHz, and 38 GHz frequency bands. All frequency bands are available with4-state modulation (QPSK) and 16- state modulation (16-QAM). The radiotransmission capacities of 4-state modulation are 2 x 2 Mbit/s, 4 x 2 Mbit/s,8 x 2 Mbit/s or 16 x 2 Mbit/s. The channel spacing is 3.5 MHz, 7.0 MHz,14.0 MHz or 28.0 MHz accordingly. The radio transmission capacities of16-state modulation are 8 x 2 Mbit/s, 16 x 2 Mbit/s or 40 x 2 Mbit/s. Thechannel spacing is 7.0 MHz, 14.0 MHz or 28.0 MHz accordingly.

For more information, see Technical specifications.

3.3 Capacity and modulation licencing

Licences that define FlexiHopper XC capacity and modulation mode aretied to the FlexiHub XC Main Unit and are currently not upgradable in thefield. FlexiHopper XC can support up to 40E1 transmission capacity, butthe capacity allowed for the FlexiHopper XC is defined by the factory-installed software licences and the FlexiHub XC Main Unit variant. Thelicences have to be ordered separately in addition to the correct FlexiHubXC Main Unit variant. See table Capacity and modulation licences neededfor the list of required licenses.

With 4 capacity licences and a modulation licence 40E1 capacity with 16-state modulation can be achieved.

3.4 ALCQ and ATPC

ALCQ (Adaptive Level Control with Quality measurement) is a method ofAutomatic Transmit Power Control (ATPC). FlexiHopper XC offers bothstandard ATPC and the more sophisticated ALCQ. ATPC and ALCQenable the radio transmitter to increase or decrease the transmit powerautomatically, according to the response received from the other end of thehop. This approach achieves more efficient utilisation of radio frequenciesthan the constant power level approach. The controlled use of transmitpower reduces interference between systems, which, in turn, allows tighterpacking of radio links within the same geographical area or at network starpoints.

The maximum transmit power is set with FlexiHub Manager or otheremployed management application. However, when ATPC or ALCQ is inuse, the radio always tries to transmit at minimum power. The idea behindALCQ is to monitor the received signal level together with the bit error ratio(BER) of the receiver, and to adjust the far-end transmitter output power toadapt to the fading conditions.

According to this invention, the bit errors detected by the forward errorcorrection (FEC) decoder are interpreted as pseudo-errors, and further,used as an additional input for ALCQ operation. In other words, thismethod can respond to degradation of signal quality before actual biterrors occur over the radio relay.

If the fading increases rapidly (multipath fading), the radio reactsimmediately by increasing the power, but not higher than the set maximumvalue. After the fading conditions resume to normal, the power is graduallydecreased. ALCQ also reacts to slow changes in the fading conditions bygradually increasing the transmit power.



Features

ATPC (Automatic Transmit Power Control) is similar to ALCQ but withoutBER measurement. ATPC controls the far-end transmit power level inorder to maintain the receive signal level above a certain user-definedthreshold level for the particular modulation method and capacity beingused. The selection between ALCQ and ATPC can be made usingFlexiHub Manager.

3.5 1+1 hot standby (HSB) protected configuration

1+1 HSB protected configuration mode ensures high reliability for theFlexiHub and the FlexiHopper XC Outdoor Unit. In this configuration, twoalternative data paths exist. The data flow path will be switched in case ofhardware failure in the current path. In 1+1 HSB protected configurationmode, the data flows from the upper radio through the FlexiHub slots 3 and6, or from the lower radio through slots 1 and 4 towards 40E1 IF PIUinstalled in slot 5.

In 1+1 HSB protected configuration mode, FlexiHub XC Main Unit isduplicated. The 40E1 LIC PIU can also be duplicated, if it is required toprotect E1 interfaces. In that case, two 40E1 LIC PIUs should be installedin slots 4 and 6. This configuration enables protection of the E1 interfacesand ensures efficiency and high reliability. 1+1 HSB protectedconfiguration is also possible when one 40E1 IF and one 40E1 LIC plug-inunits are installed in the FlexiHub, but in that case there is no protection forthe E1 interfaces.

When using 8E1 PIU instead of 40E1 IF PIU, 8E1 PIU doesn't have to beduplicated since it is not protected in 1+1 HSB configuration.

The radio of the Outdoor Unit must be duplicated as well. In theconfiguration with two radios installed, one of them acts as primary and theother one as protecting. Figure FlexiHopper XC 1+1 HSB protectedconfiguration illustrates FlexiHopper XC Outdoor Unit connection to theFlexiHub. Note that the protecting radio is connected to the protectingFlexiHub XC Main Unit (slot 3), and the primary radio - to the primaryFlexiHub XC Main Unit (slot 1).



Figure 5. FlexiHopper XC 1+1 HSB protected configuration

Note that in order to implement 1+1 HSB protected mode, you need toinstall an additional FlexiHopper XC radio and an additional FlexiHub XCMain Unit.

FlexiHopper XC Outdoor Unit structure

A Flexbus cable is used to connect the FlexiHopper XC Outdoor Unit to theFlexiHub. The cable carries data between the FlexiHub and FlexiHopperXC Outdoor Unit in full-duplex mode. It also carries the required DC powerfrom the FlexiHub to the Outdoor Unit.

On the modem board, the DC voltage and the data signals are separatedfrom each other. DC voltage is converted to multiple DC voltage levels inthe power supply of the modem board and those voltage levels aredelivered to other units of the Outdoor Unit.

The modem board also includes the embedded microprocessor system,which is used to control all units within the Outdoor Unit as well as tocommunicate with the FlexiHub and the far-end radio. The interfacebetween the modem board and the RF parts consists of analog I and Qsignals.

In the transmitter (Tx) part, the data coming from the cable is demodulatedand reshaped in such a manner that it can be sent over the radio interface.The modulation of the Tx signal happens in the modem ASIC (Application-Specific Integrated Circuit) that also takes care of the Reed-Solomonencoding as well as Tx filtering.

The modem ASIC supplies the TxI and TxQ signals through the digital-to-analog converters to RF functions. In the transmitter, direct conversionarchitecture has been implemented to enable the use of a singlemicrowave local oscillator.

After the up-conversion, the signal is amplified enough in order to attainthe required maximum output power level. A temperature-compensatedpower detector is used to monitor the power level after the high-poweramplifier, and to drive the voltage variable attenuator in order to obtain therequired output power level.

On the receiver (Rx) side, single intermediate frequency (IF) conversionarchitecture is used. After the low-noise amplifier (LNA), the receivedsignal is down-converted to the IF. The automatic gain control (AGC) isused to obtain a constant rms-power level for the I/Q-demodulator.

In the I/Q-demodulator, the IF signals are converted to RxI and RxQsignals, which are supplied to the modem ASIC through the analog-to-digital converters.

Modem ASIC carries out Rx filtering, adaptive equalisation, timing andcarrier recovery, decision making and Reed-Solomon decoding. Thedemodulated data is then converted to the format that can be transmittedto the FlexiHub through the Flexbus cable.



4.2 Antennas

FlexiHopper antennas are available in eight sizes: 20, 30, 60, 90, 120,180, 240 and 300 cm. The polarisation of the antenna can be easilychanged by rotating the Outdoor Unit and the antenna feeder through 90°.

Figure 7. FlexiHopper XC Outdoor Unit with an integrated 30 cm FlexiHopperantenna and FlexiHopper Alignment Unit

The Outdoor Unit is directly connected to a small (20, 30, or 60 cm) singleantenna by using the FlexiHopper Alignment Unit or to a larger (90, 120and 180 cm) single antenna by using a snap-on adapter. No waveguidesare needed. The alignment is carried out by using a ratchet or a battery-operated screwdriver.

All antennas can be used separately by connecting a flexible waveguidebetween the antenna and the radio.

Larger antennas (240 cm and 300 cm) can only be installed separately. 2.4m single polarised (SP) antenna is also available with a split reflectoroption and the 3.0 m antennas are delivered only with the split reflectoroption.



FlexiHopper XC Outdoor Unit structure

FlexiHopper XC uses the same FlexiHopper antennas and FlexiHopperAlignment Units as the rest of FlexiHopper family, which make a possibleupgrade to FlexiHopper XC easy, as no antenna re-alignment is needed.For more detailed information, see Nokia Siemens Networks FlexiHopperXC Antennas, Alignment Units and Electrical Specifications.

4.3 Powering concept

The power is supplied to the FlexiHopper XC Outdoor Unit from theFlexiHub. The FlexiHopper XC has an N connector (female) and theFlexiHub has a TNC connector (female). The units are connected togetherwith a single coaxial Flexbus cable, that carries required DC power anddigital baseband data from the FlexHub to the FlexiHopper XC OutdoorUnit. On the modem board, the DC voltage and the data signals areseparated from each other. DC voltage is converted to multiple DC voltagelevels in the power supply of the modem board and those voltage levelsare delivered to other units of the Outdoor Unit. For the block-diagram ofthe FlexiHopper XC Outdoor Unit, see Functional units.

The low power consumption of the FlexiHopper XC Outdoor Unit results inhigh reliability and a long running time on battery backup. For the powerconsumption values, see Outdoor unit power supply.

In single configuration mode, one FlexiHub XC Main Unit provides thepower needed for the FlexiHopper XC. In 1+1 HSB protected configurationmode, the two FlexiHub XC Main Units share the power loading. The loadsharing is implemented with active load balancing, which ensuresefficiency and reliability, as the load is equally distributed between theredundant power supplies. For more information on powering of theFlexiHub, see Powering concept in Product Description for Nokia SiemensNetworks FlexiHub.

Grounding connector - used for connecting a 16 mm2 grounding wire. Thepurpose of protective grounding is to keep the electrical potential of theequipment at the same level as the potential of the surrounding ground.This prevents generation of dangerous voltages between the equipmentand the ground. Because of the high locations of the radio and basestation equipment, equipment stations are particularly susceptible tolightning strokes.

Flexbus connector - used for connecting coaxial Flexbus cable to theOutdoor Unit. Flexbus cable carries power and digital baseband data fromthe FlexiHub. The FlexiHopper XC Outdoor Unit has an N connector(female) and the FlexiHub has a TNC connector (female). FlexiHopper XCuses the same Flexbus cables as other Hopper family products. Note thatthe Flexbus cable has to be grounded.

AGC connector - measurement point for the AGC (automatic gain control)voltage. AGC voltage measurement is needed when aligning the antennafor connecting DC voltage meter.

6 Upgrading FlexiHopper XC Outdoor Unit

6.1 Increasing transmission capacity

Each FlexiHopper XC Outdoor Unit can support up to 40E1 transmissioncapacity, but the capacity allowed for a specific XC Outdoor Unit is definedby the factory-installed SW licences and the FlexiHub XC Main Unitvariant. Only a correct combination of these two factors - FlexiHub XCMain Unit and factory-installed licences - will give the desired capacity andmodulation. These licences must be ordered separately, in addition to theright FlexiHub XC Main Unit variant. Therefore no additional parts areneeded for increasing transmission capacity of the FlexiHopper XCOutdoor Unit.

The licences defining the FlexiHopper XC capacity and modulation modeare tied to the FlexiHub XC Main Unit and are currently not upgradable inthe field. Later FlexiHopper XC releases will support also fieldupgradability with licence keys.

For more information see Ordering Parts and Accessories for NokiaSiemens Networks FlexiHopper XC and corresponding sections in ProductDescription for Nokia Siemens Networks FlexiHub.

6.2 Upgrading to 1+1 hot standby (HSB) protectedconfiguration

It is possible to upgrade to 1+1 HSB protected configuration after the initialinstallation. Two FlexiHopper XC radios and their cabling are alwaysneeded for the installation. One radio acts as primary and the other one asprotecting. Note that this may require obtaining additional parts andaccessories depending on the existing antenna setup.
