  • インサイドアウト:固定オペレーター向けのクラウドソーシングされたHetNet
  • 注目を集めているいくつかのオペレーターはフェムトセルに基づいたインサイドアウトアプローチを積極的に検討
  • その他の固定モバイルコンバージェンス(FMC)アプローチが利用可能


  • オリジナルの消費者向けフェムトセルビジネスケースは不十分なサービス範囲に促進されていたが、新たなビジネスモデルはより堅調な需要を持つ見込み
  • インサイドアウト戦略は電話サービスの活性化を目指す固定オペレータおよびMSO向けの機会
  • インサイドアウトモデルは、関連の高い家庭用トラフィックおよびパブリックスモールセルによってリーチ可能なオフトラフィックの量に非常に依存する、ほか


  • 現在、適切なスペクトルは潜在的インサイドアウトオペレーターの管理下にほとんど無い
  • 将来の適切なスペクトルの不足は無いが、ほとんどはライセンスが免除され、またデバイスのエコシステムが未熟
  • スモールセルバックホール向け固定ブロードバンド接続のインストールベース使用にはいくつかの欠点がある、ほか


  • インサイドアウトオペレーターは顧客獲得コストが低いが、信頼性・ブランドの課題がある
  • 追加コスト・収益のサマリー
  • MVNOオートフィルのコストはインサイドアウトオペレーターのビジネスケースにとって重要、ほか

著者・Analysys Masonについて



‘Inside-out' is one way towards a converged world based on millions of small cells - fixed and cable operators have a real current cost advantage over mobile operators working ‘outside-in'.

The ‘inside-out' approach to wireless network provision describes a strategy fixed and cable operators are adopting to develop low-cost, high-capacity vast national public heterogeneous networks (HetNets) and services on the back of their existing fixed broadband access infrastructure. All cells and access points operate in open-access mode, and additional capacity for areas with no coverage is provided on a wholesale basis by a mobile network operator. The approach could be successful, profitable, and disruptive to legacy mobile operators.

This report analyses the technical and commercial challenges that operators adopting the ‘inside-out' approach to wireless network roll-out will face.

The report:

  • defines the approach and investigates the business drivers and opportunities
  • assesses the technical challenges, including choice of spectrum, interference, cell identity management, the suitability of fixed broadband as backhaul and alternative approaches to fixed-mobile convergence (FMC)
  • assesses the commercial challenges around scale, distribution, wholesale contracts and pricing, and offers a top-level total cost of ownership model
  • provides recommendations for fixed, cable and mobile operators, as well as for network equipment providers (NEPs).


This report includes information on the strategies of the following companies.

  • BT
  • Free Mobile
  • Google Fiber
  • Kineto
  • Liberty Global
  • Republic Wireless
  • Scratch Wireless
  • SoftBank
  • TalkTalk
  • Ziggo

  • 7. Executive summary
  • 8. Recommendations
  • 9. Recommendations
  • 10. Inside-out and other approaches to FMC
  • 11. Inside-out: crowd-sourced HetNets for fixed operators
  • 12. Several high-profile operators are actively considering the femtocell-based inside-out approach
  • 13. Other fixed-mobile convergence (FMC) approaches are available
  • 14. Business drivers and opportunities for fixed and cable operators
  • 15. The original consumer femtocell business case was driven by poor coverage, but new business models will have more robust demand
  • 16. The inside-out strategy is an opportunity for fixed network operators and MSOs to rejuvenate their telephony services
  • 17. The inside-out model depends critically on a high relative volume of at-home traffic and of traffic reachable by public small cells
  • 18. Inside-out operators see an opportunity to undercut MNOs on the price of mobile voice and data
  • 19. Unlimited mobile voice bundles are becoming more common, but this affects only the incremental, and not the actual, cost of voice services
  • 20. Inside-out quadruple-play bundles make commercial sense only insofar as end users value the wired connection
  • 21. Inside-out operators aim to capitalise on their fixed infrastructure assets to reduce the cost of mobile backhaul
  • 22. Inside-out operators can capitalise on oversupply of mobile to force a good MVNO deal
  • 23. Technical challenges
  • 24. Little suitable spectrum is currently in the hands of potential inside-out operators
  • 25. There is no shortage of suitable future spectrum, but most will be licence-exempt and the device ecosystems are immature
  • 26. Using the installed base of fixed broadband connections for small-cell backhaul has several drawbacks
  • 27. FMC options that are less costly than femtocells are available, but they have disadvantages
  • 28. Radio interference management requirements increase as the number of cell sites and frequencies used increase
  • 29. Self-organising networking (SON) reduces the operational difficulties and costs associated with small-cell networks, but it has risks
  • 30. Interference between 2.4GHz Wi-Fi and 2.6GHz LTE can cause problems in the home router
  • 31. Commercial challenges
  • 32. Inside-out operators will have the scale for low customer-acquisition costs, but have credibility and brand challenges
  • 33. Summary of additional costs and revenue
  • 34. The cost of MVNO outfill is critical for the business case of an inside-out operator
  • 35. An inside-out operator would have to balance the merits of per-unit or per-subscriber charges, but more-formal bitstream models may emerge
  • 36. Inside-out models could prove both profitable and disruptive, but there are fixed start-up costs to overcome
  • 37. Some broader implications of an inside-out approach
