3 FeaturesNokia FlexiHopper Microwave Radios have many advanced features in additionto all the essential microwave radio features. This chapter describes these featuresin more detail.
A Nokia FlexiHopper network element consists of an indoor unit (IU) and anoutdoor unit (OU). The units are connected together with a single coaxial cable,Flexbus. The Flexbus cable can be up to 300 m long.
3.1 One unit, all capacities; one platform, allfrequencies
The Nokia FlexiHopper Microwave Radio family includes models for the 13, 15,18, 23, 26, and 38 GHz frequency bands. The radio transmission capacity of allNokia FlexiHopper models is 2 x 2, 4 x 2, 8 x 2, or 16 x 2 Mbit/s. This can beselected using the node manager without any hardware changes.
Nokia FlexiHopper – Lightweight outdoor unit
The Nokia FlexiHopper outdoor unit is small and lightweight: 21 x 23 x (12 -21)cm 3 / 4.0 - 5.5 kg. All frequency bands use the same technical concept and asimilar mechanical construction. The only mechanical difference betweenoutdoor units is the length of the collar which houses the antenna filter; the lowerthe frequency, the longer the filter and the collar.
• The transmitter uses π /4-DQPSK (differential quadrature phase shiftkeying) modulation, which has the advantages of a narrow spectrum andgood output power efficiency.
• Typical maximum output power is 16 - 20 dBm (dependent on thefrequency band).

• The output power can be adjusted electrically via the node manager.
• Hop length is from 3.0 km (38 GHz radio with 20 cm antenna at 16 x 2Mbit/s capacity) up to over 50 km (13 GHz or 15 GHz radios with 120 cm
antenna at 16 x 2 Mbit/s capacity). These values are calculated with0.005% unavailability in 42 mm/h rain rate conditions (European climate)with guaranteed system values. When the radios are set at lower capacity,the hop lengths are even longer.
3.2 One indoor unit supports two outdoor units
Nokia supplies four different indoor units for Nokia FlexiHopper to provideoptimal features for different environments. All frequency bands use the sameindoor units. One indoor unit (excluding FC RRI) can support two outdoor units.
Up to four outdoor units can be connected to one FIU 19 indoor unit. When fouroutdoor units are used, one of the transmission directions must be protected.
The full radio capacity from 2 x 2 Mbit/s up to 16 x 2 Mbit/s is available with allindoor unit models. The add/drop capacity varies according to the indoor unitmodel. The same indoor units can also be used with Nokia MetroHopper at 4 x 2Mbit/s radio capacity. The main features of each indoor unit are described below.

More examples of the possibilities offered by the Flexbus can be found in Section4.2 ‘Site configuration examples’.
3.5 Reliable connections
Nokia FlexiHopper provides reliable connections and high availability in allenvironments. The reliability of the equipment is excellent due to the highintegration.
Forward error correction
Nokia FlexiHopper radios use forward error correction (FEC) and interleaving toimprove signal quality. The forward error correction uses Reed-Solomon (RS)coding. The interleaving is selectable between off, 2-depth, and 4-depth modes.
ALCQ (Adaptive Level Control with Quality measure)
ALCQ is a method for automatic transmit power control. This feature enables theradio transmitter to increase or decrease the transmit power automatically,according to the response received from the other end of the hop. This approachachieves more efficient utilisation of radio frequencies than the constant levelapproach. The controlled use of transmit power reduces interference betweensystems, which in turn allows tighter packing of radio links within the samegeographical area or at network star points. For more information on ALCQ, referto the ALCQ and Automatic Fading Margin Measurement in FlexiHopper
Microwave Radio application note that can be obtained upon request.
The common idea behind the ALCQ is to monitor the received signal leveltogether with the bit error ratio (BER) of the receiver, and to adjust the far-endtransmitter output power to adapt to the fading conditions. In addition to theseconventional ALCQ operation mechanisms, Nokia FlexiHopper also applies anovel pseudo-error monitoring for controlling ALCQ. According to this Nokiainvention, the bit errors detected by forward error correction (FEC) decoder areinterpreted as pseudo-errors, and further, used as an additional input for ALCQoperation. In other words, this invention can respond to degrading of signalquality before actual bit errors occur over the radio relay.
Automatic fading margin measurement
During the commissioning of a microwave radio, the operator may wish tomeasure the fading margin of the radio hop. Traditionally this has required muchwork and additional hardware, such as RF (radio frequency) attenuators. In NokiaFlexiHopper, the fading margin measurement is automatic and can be startedsimply by using software. For more information, refer to the ALCQ and
Automatic Fading Margin Measurement in FlexiHopper Microwave Radioapplication note that can be obtained upon request.

3.6 Protection options
In single use, the signal is normally not protected against equipment and
propagation faults (exception: ALCQ can provide some protection againstpropagation faults). In the event of a fault, the connection will remain broken untilthe equipment fault has been repaired or the cause for the propagation fault goesaway.
Three types of transmission protection are available with Nokia FlexiHopper:equipment protection, propagation protection, and loop protection.
Equipment and propagation protection methods protect a single transmissionlink. In both methods, a pair of FlexiHopper outdoor units (and possibly also apair of indoor units) are protecting each other.
Loop protection is actually a type of network topology. It differs from the formertwo methods in that it protects an entire transmission route and not a single link.If required, single links in a loop can be protected with equipment or propagationprotection methods.
Equipment protection
Equipment protection protects a single transmission link against faults in theequipment. Equipment protection can be implemented with either one (FIU 19,RRIC) or two indoor units (FIU 19 only). When two FIU 19 units are used, theyare connected through an expansion unit.
Equipment protection can be implemented by any of the following methods:
• hot standby (HSB)
• HSB + space diversity
• frequency diversity
• polarisation diversity.
HSB can also be implemented with a single antenna. Two outdoor units areconnected to one antenna via a directional coupler. The method is known as one-antenna protection and it is especially useful with larger antennas (120 and 180cm). One-antenna protection eliminates the need to install expensive tower
support structures for two antennas, and may also reduce site rent costs, if the rentpaid by the operator is determined according to the number of antennas installed.
Propagation protection
Propagation protection is used to minimize the number of traffic interruptions dueto interference in the transmission path. Propagation protection can beimplemented with either one or two indoor units (FIU 19 only). When two FIU19 units are used, they are connected through an expansion unit.

The changeover caused by propagation interference is error-free (hitless).
Propagation protection can be implemented by any of the following methods:
• HSB + space diversity• frequency diversity
• polarisation diversity.
Loop protection
Loop protection protects both against equipment faults and against interference inthe transmission path. When a fault is detected, traffic is routed in the oppositedirection around a ring.
With Nokia FlexiHopper the capacity of a loop can be up to 16 x 2 Mbit/s. The
add/drop capacity at a loop site depends on the indoor unit used.
The FXC RRI indoor unit has an integrated cross-connection section whichenables loop protection. With the RRIC indoor unit, loop protection is availabletogether with the TRUx base station transmission unit. Loop protection can alsobe implemented with the FIU 19 indoor unit, if external cross-connectionequipment is used (Nokia DN2 Dynamic Node Equipment, for example).
3.7 Comprehensive integration
Talk-family
Nokia FlexiHopper radios provide mechanically integrated solutions in NokiaTalk-family base stations and 19-inch installations. The 19-inch indoor unit, FIU19, can be installed in the Nokia Extratalk Site Support System cabinet or anystandard 19-inch subrack. The base station integrated indoor unit, RRIC, fits intothe Nokia Citytalk and Nokia Intratalk base stations. Inside the base station, RRICunit and TRUx cross-connect are integrated and optimised to work together.
Nokia MetroSite
Nokia FlexiHopper is fully compatible with the Nokia MetroSite capacitysolution. Nokia MetroHopper is usually used to provide access for NokiaMetroSite sites, but when longer hop distances and higher capacity are required,Nokia FlexiHopper is used.
Nokia FlexiHopper is connected to Nokia MetroSite by the FC RRI or FXC RRIplug-in transmission unit. The FC RRI transmission unit is installed in NokiaMetroSite GSM Base Station and it provides one 2 Mbit/s connection. Forgrooming of transmission capacity, the FXC RRI transmission unit can beinstalled in Nokia MetroSite GSM Base Station or Nokia MetroHubTransmission Node. FXC RRI has an integrated 8 kbit/s cross-connection andgrooming capability, with no need for external equipment on-site.

Capacity in the urban environment
In urban areas the emphasis is on smaller equipment to reduce site costs and spacerequirements. High density urban networks also require high capacity
transmission media. Nokia FlexiHopper is a compact product withcomprehensive integration to site.
Nokia FlexiHopper is mainly used in macrocellular sites. It can also be used inthe microcell layer when there is a need for higher capacities or longer radio hopsthan can be achieved with Nokia MetroHopper. Nokia FlexiHopper supports allstandard network topologies: chain, star and loop. Equipment protection andpropagation protection methods are available for point-to-point connections.
Coverage in the rural environment
In rural areas where the capacity required may be low, the focus is on building thenetwork at the lowest cost. Nokia FlexiHopper can provide a low cost solutionbecause of its site integration. In many configurations only one indoor unit isrequired for two outdoor units.
Operators are also interested in building coverage by enhancing the cell range orby focusing on covering roads, in order to reduce the number of sites. NokiaFlexiHopper 13 and 15 GHz radios can be utilized in rural areas where longerhops are required.
After the initial roll-out phase the capacity required may increase. With itsprogrammable capacity, Nokia FlexiHopper grows with the evolving network.
Capacity in fixed networks and dedicated networks
In fixed or dedicated networks, Nokia FlexiHopper provides a competitivealternative to leased lines. Due to its fast roll-out and high reliability, NokiaFlexiHopper is often the better choice, when high capacity and reliability are thekey factors.

At 13 and 15 GHz and with 1–antenna HSB, an integrated antenna cannot be usedand, thus, a separate antenna is needed.
Also, at 13 and 15 GHz, a flexible waveguide of 1 m is normally used. In this case,add 0.4 ± 0.2 dB for 13 GHz and 0.6 ± 0.3 dB for 15 GHz to the given values. If a longer waveguide is needed, an elliptical waveguide can be used. To get the
total insertion losses in this case, add the attenuation of the elliptical waveguides(0.12 dB/m for 13 GHz and 0.16 dB/m for 15 GHz) to the given values.
At 18, 23, 26, and 38 GHz, a short waveguide (190 mm or 127 mm) is includedin the coupler. Normally an integrated antenna is used, but a separate antenna canbe used with an additional waveguide. To get the insertion losses in this case, addthe attenuation of the additional waveguide to the given values.
