Executive summary The pioneers in legacy network rationalisation are found in the Asia-Pacific region. Here operators started rationalising 2G services as early as 2008 to 2012, with many others following in more recent years. Drawing on the experience of six case study markets from the Asia-Pacific region, this report explores the most suitable market, regulatory and commercial conditions for achieving a smooth and successful switch-off. The case study markets differ in terms of characteristics of the mobile market, extent of regulator involvement and approaches to spectrum allocation and management. As such, the impact of each of the key drivers on the decisions varied from market to market, with spectrum related issues being the most prominent driver. Decisions to sunset 2G services and, more recently, 3G MNOs: key risks services are based on a wide range of considerations. Mobile • Customer churn, particularly when operators do not switch network operators (MNOs) seek to rationalise legacy network off at the same time technologies as more spectrally efficient technologies become • Uncertain demand for new services and capacity available and the nature of consumer demand changes. • The cost of migrating M2M connections MNOs: key drivers and benefits • Possible changes in coverage, particularly if the new • Refarm spectrum and deploy most cost-effective technology (such as VoLTE) does not provide the same technology; coverage as the replaced legacy technology on the same • Reduce operational costs; band, or it operates in a frequency band that does not provide adequate indoor coverage without further network • Meet increased demand for mobile broadband and data investment intensive applications from smart devices; • Potential brand damage if some customers are left • Potential market and competitive effects for the first mover; without coverage, are forced to upgrade handsets or large • Meet Government expectations of deploying the latest numbers of M2M connections are disconnected for business innovative mobile technology. customers. Comprehensive strategies require an understanding of risks for both operator and consumer. 2 LEGACY MOBILE NETWORK RATIONALISATION Decisions are invariably driven by operators, with differing Delays in scheduling 2G network rationalisation projects may degrees of involvement by regulatory authorities. The latter is, be caused by the size of operators’ customer bases for 2G for example, needed if spectrum allocations are not technology on M2M and IoT applications, particularly where long term neutral. However, consumer protection is typically the paramount support agreements exist. Given that technical options exist for concern of regulators. Thus, a smooth process depends on careful migrating such applications, the cessation decision for 2G and planning of a transitional period, obtaining regulatory approval 3G technologies is an economic one. Key factors in the decision where necessary, and above all ensuring effective customer include the size and type of subscriber base, current and forecast engagement. Based on the experience of the case study markets revenues, and the cost of substitution. best practice approaches encompass several key characteristics: For regulators, the implications of a 2G or 3G switch-off should • A transitional period of around three years, with preparations be considered in relation to key spectrum management issues. commencing earlier than formal public announcements; These include the need for minimum spectrum allocations suitable for utilising newer technologies and the possibility that • Coverage of any new technology that matches what was lengthy renewal of 2G spectrum allocations may result in unused previously offered; spectrum, particularly in sub-1 GHz bands. • A reasonable formal notice period, given specific market circumstances and potential obligations; • A well-designed campaign involving direct targeting of affected customers, possibly assisted by the regulator; • Upgrade incentives for customers, including comparably priced plans, and handset recycling initiatives as part of any 2G or 3G switch-off; and • A quality of service that is maintained during and after the transition. 3 LEGACY MOBILE NETWORK RATIONALISATION 2.

    McKinsey Global Institute McKinsey Global Institute Nigeria’s renewal: Delivering renewal: Nigeria’s inclusive largest growth economy in Africa’s July 2014 Nigeria’s renewal: Delivering inclusive growth in Africa’s largest economy The McKinsey Global Institute The McKinsey Global Institute (MGI), the business and economics research arm of McKinsey & Company, was established in 1990 to develop a deeper understanding of the evolving global economy. Our goal is to provide leaders in the commercial, public, and social sectors with the facts and insights on which to base management and policy decisions. MGI research combines the disciplines of economics and management, employing the analytical tools of economics with the insights of business leaders. Our “micro-to-macro” methodology examines microeconomic industry trends to better understand the broad macroeconomic forces affecting business strategy and public policy. MGI’s in-depth reports have covered more than 20 countries and 30 industries. Current research focuses on six themes: productivity and growth; natural resources; labour markets; the evolution of global financial markets; the economic impact of technology and innovation; and urbanisation. Recent reports have assessed job creation, resource productivity, cities of the future, the economic impact of the Internet, and the future of manufacturing. MGI is led by three McKinsey & Company directors: Richard Dobbs, James Manyika, and Jonathan Woetzel. Michael Chui, Susan Lund, and Jaana Remes serve as MGI partners. Project teams are led by the MGI partners and a group of senior fellows, and include consultants from McKinsey & Company’s offices around the world. These teams draw on McKinsey & Company’s global network of partners and industry and management experts.

  • Networking Packet Broadcast Storms
    Lesson Learned Networking Packet Broadcast Storms Primary Interest Groups Balancing Authorities (BAs) Generator Operators (GOPs) Reliability Coordinators (RCs) Transmission Operators (TOPs) Transmission Owners (TOs) that own and operate an Energy Management System (EMS) Problem Statement When a second network cable was connected from a voice over internet protocol (VOIP) phone to a network switch lacking proper settings, a packet broadcast storm prevented network communications from functioning, and supervisory control and data acquisition (SCADA) was lost for several hours. Broadcast storm events have also arisen from substation local area network (LAN) issues. Details A conference room was set up for a training class that needed to accommodate multiple PCs. The bridge protocol data unit (BPDU) packet propagation prevention setting was disabled on a port in the conference room in order to place a network switch off of that port. Upon completion of the training, the network switch was removed; however, the BPDU packet propagation setting was inadvertently not restored. As part of a telephone upgrade project, the traditional phone in this conference room was recently replaced by a VOIP phone. Later, an additional network cable was connected to the output port of this VOIP phone into a secondary network jack within the conference room. When the second network cable was connected from a VOIP phone to a network switch lacking proper settings, a switching loop resulted. Spanning tree protocol is normally used to prevent switching loops from propagating broadcast packets continuously until the network capacity is overwhelmed. A broadcast packet storm from the switching loop prevented network communications from functioning and SCADA was lost for several hours.
