NSN Business Plan: Justification and Timing

• NSN business logic– The feature improves NSN's competitiveness (see next slide)

• Negative impact analysis– Huge benefit of FlexiPacket Radio is that it could be applied to tail and chain

sites without indoor unit (FlexiPacket Hub), which supports the “Zero footprint” story and makes it in terms of pricing highly competitive.Not providing this feature leads to higher cell site TCO and thus jeopardizes the competitive advantage of NSN’s solution.

• Feature market potentialGood Sales Record with Hopper-family with UltraSite Integrated Indoor units

• Selling window– >2015 for FlexiPacket Radio + Successor

• Latest delivery date/release required by the customer: – FlexiPacket Radio concept (incl. chain/hub-sites and 3G co-location) ready in

BO2010


Customer Business Case• No need for (as integrated to Flexi EDGE BTS)

– separate Indoor Unit – direct connection from FPR to FlexiEDGE– external synchronization solution with sync.Ethernet (like GPS in BTS, external

server in BSC-site for ToP)• Lower investment/installation/maintenance costs, faster site roll out• Local commissioning and troubleshooting for FlexiPacket Radio links

without touching the cabling from BTS to MWR and without interrupting Abis traffic

• Low total cost of MWR Solution=> Minimization of active components on the site, thus optimized MTBF,

minimized site power consumption, and thus minimized total cost of ownership

FlexiPacket Radio is THE future MWR product of NSN, the usage of the GSM/EDGE BTS as a kind of “indoor

unit” is the customer key benefit.

Back-Up Slides


JustificationPrevious microwave radio platform (Flexi/MetroHoppers) together with the BTS integrated indoor units provided the opportunity to realize zero footprint microwave radio solutions for tail and chain sites – a unique feature in the market.This has been one of the key drivers for Flexihopper success along with NSN 2G BTS deployments, especially in India, and created a beautiful hook between Radio Access and MicroWave Radio Sales.Clearly the era of Flexihopper will come to an end as capacity needs increase and backhaul technologies evolve from TDM technologies towards IP and Ethernet over the coming years.The NSN packet era microwave radio will be the FlexiPacket Radio with the optional indoor unit FlexiPacket Hub, based on A-series portfolio product.Having specific FlexiPacket Radio-related features in BTS Transport Sub-Modules, that would provide a unique competitive advantage, thus can not be reached with any other NSN/non-NSN radio like this would be highly desired.

Zero Footprint and Integration with FlexiBTS


Managing FPR through FlexiEDGE LMP 1/2Problem • FlexiPacket Radio provides Ethernet interface but it doesn’t offer any out-of-band management via a

dedicated interface. Thus a feature needs to be provided that supports locally commissioning & troubleshooting FlexiPacket Radio links via FlexiEDGE BTS local management port without touching the cabling from BTS to MWR and without interrupting traffic. Without this feature local commissioning & troubleshooting of FlexiPacket Radio stays unnecessarily complex.

Feature description• FlexiEDGE BTS shall support that

– near-end FlexiPacket Radio connected to one of its Ethernet transport interfaces

– associated far-end FlexiPacket Radio • can be managed from a Local Management Tool

being attached to Local Management Port on System Module for local commissioning and troubleshooting.

• Note: Similar feature applies as well to FlexiWCDMA, WCDMA Ultrasite

• (AXCF) and FlexiWiMax (implementation might varies)

(M) = mandatory information(O) = optional information(M/o) -> Big/small feature

Managing FPR through FlexiEDGE LMP 2/2Negative impact analysis (from Wimax)• Consequences in detail

– FlexiPacket Radio chain site scenarios or FlexiPacket tail site with collocated Ethernet equipment scenarios not well supported

▪ FTYA supports only 2 inbuilt electrical Ethernet interfaces, thus for hitless local management access technician needs to carry electrical SFP, when local access to FlexiPacket Radio only works over Transport Ethernet interfaces

– Customer using BTS-integrated IDU are used to manage MWR over BTS LMP (e.g. FTFA and IFUE)– Bandwidth for FlexiPacket Radio management plane traffic is neither guaranteed nor shaped on MWR link as R-

channel can not be taken into use for it due to absence of VLAN tagging (unless LMT supports VLAN tagging and connects to Transport Ethernet interfaces)

– FlexiPacket Radio management plane is not “out of band” as customers are used to due to absence of VLAN tagging (unless LMT supports VLAN tagging and connects to Transport Ethernet interfaces)

– Either management traffic from remote must not be VLAN tagged as well or LMT must support VLAN tagging

Work effort in other technologies• WiMax BTS: 6mm per BTS platform

Interim solution•Interim solution is direct IP management connection from BTS Ethernet access port to the FlexiPacket Radio. Interim solution requires special skills by service personnel and increases site commissioning time significantly. Procedure is fully manual and human errors are expected. Estimated extra site time 20min.

Fast and automated solution for installation and commissioning.A key advantage of the common RA / MWR offerings.

Requirements (NSN-estimate)In scope:•FlexiPacket Radio support without indoor unit for tail/chain-sites (testing 4.5 manmonths)•Synchronous Ethernet slave support (testing 0.5mm)•Timing over Packet IEEE1588-2008 (testing 0.5mm)•Adaptive Clock Recovery (testing 0.5mm)•Managing FPR through FlexiEDGE LMP (SW/testing 8mm)

– O&M through Ethernet connection

NOT in scope:•Power over Ethernet from BTS (SW/HW/testing 12mm) dropped, no bc•Synchronous Ethernet slave: clock regeneration (HW/SW 14mm) included in PASI•Ethernet QoS monitoring in BTS (SW/testing 14mm) dropped, not mandatory (origin in 3G)

– differentiate counters per quality classes (EF; AF, Best Effort, etc) versus only one for complete traffic

•Hot Stand-By protection (SW/testing 11mm) dropped, not valid for tail-sites•Ethernet ring protection (SW/testing 0.5mm) dropped, no support in BSS-elements generally

Total effort 14 manmonths


Open questions/comments?•3rd party MWR-radio support? PoE implementation for FPR not fully standard compliant, therefore the support for other MWR-radios is limited•Winlink?•FPR: G.8031 1:1 path protection (analogous to SDH's SNCP)?•Power over Ethernet from BTS

– FPR has an external power supply interface (-48V DC)– FPR can use external power supply with power injector in Ethernet-cable

▪ Flexi EDGE power module can provide needed power supply– Only 30% of FIYB / FIQB would use PoE– There is an alternative solution with external power feeder available (currently under development by

MWR Product line)– There is a huge probability that some customers insists on surge protection for PoETH, which would

anyway require an external power feeder box (not at all possible to implement on FIYB / FIQB) So 30% forecast might even be too positive

– PoE would also increase the technical and schedule risk for FIYB / FIQB significantly•Ethernet ring protection: MWR does not support nor prioritize this high•Ethernet QoS monitoring in BTS: needed in chain site?

– Feature deals with throughput counters per PHB and connection admission control monitoring•Only FE in FlexiEDGE is supported for FPR – not Gigabit Ethernet interface•Managing FPR through FlexiEDGE LMP

– FPR does not have dedicated interface for this (no out-of-the band management)– customers are used to manage MWR over BTS LMP

•HSB in Tail-sites only? HSB comes with Ethernet Hub site anyway (see network scenarios)•Synchronous Ethernet slave: clock regeneration (SW 13mm): included in PASI
