With VoLTE and VoWifi, voice becomes just another application enabled by mobile data LTE-U, LTE-LAA, LTE-LSA, and LTE-M allow extending LTE to new spectrum bands to extend capacity and types of devices (IoT) ready coming soon roadmap&maturity Commercially available in 2-4 years  LTE-x technologies are still in a trial phase and will be available in 2018-2019.  LTE-U : Ericsson & Qualcomm started trials since 2014. MTN & US operators joined them in 2016  LTE –M : after a standardization phase, Sierra Wireless plans to launch a 1st field prototype in 2017. Commercially available  By 2017, most operators will provide VoLTE & VoWifi.  Currently :  VoLTE & VoWifi are available in US + APAC, rolling-out in Europe  VoLTE : launched by 60+ operators in 39 countries  VoWifi : launched by 100 operators
  7. © 2017 BearingPoint France SAS 7 Both customers and operators will benefit from these 4G enhancements  LTE-U & LSA will improve the bandwidth for existing apps without heavy network spendings  LTE-M will enable new IoT applications better voice experience due to :  [VoLTE] lower latency for connection  [VoX] more stability in data rate (QoS)  [VoX] ability to use a data connection meanwhile  [VoWiFi] better indoor coverage reduced call charges, mainly in roaming situations Telemedicine, with VoWiFi patients and doctors can communicate visually and verbally as they review a patient’s vitals dashboard in real time improved bandwidth & latency useful for gluttonous services :  video : high quality (4K), live streaming, videoconferencing…  live gaming  telemedicine energy savings can be made in smart buildings in which water & electricity consumption are monitored and adapted to weather conditions  enabling unified communication services  increased network capacity with limited investment  off-loading mobile networks on local networks like WiFi  get more revenues from data OTT services like streaming & gaming without buying spectrum  improve market share on the IoT market without spending on expensive LPWA networks customers operators use case Smart Buildings, with LTE-M  VoLTE : a better voice quality for customers, and an enabler for unified communication services  VoWifi : roaming savings with better indoor coverage, and a way to off-load mobile networks minor benefits major benefits voice data
  8. © 2017 BearingPoint France SAS 8 The Promise NFV/SDN increases flexibility and responsiveness for networks operations, and hence brings an adapted response to customers and operators need for quick network services evolutions Network Functions Virtualization (NFV) and Software Defined Networks (SDN) might speed up the integration of these enhancements on operator’s networks • Rapid service innovation and expansion with less risk • Elastically scale and utilize network resources more efficiently • Lower operating costs through homogenized physical infrastructure NFVSDN • Separation of control and forwarding functions • Centralization of control • Ability to program the behavior of the network using well-defined interfaces Why is it important ? 4G Mobile Network functions, such as Evolved Packet Core (EPC) and voice over LTE (VoLTE), are now deployable in the cloud. This will enable an easier upgrade and scalability for Network functions and applications. Particularly because the services and functions that relay on the 4G core (optimization, analytics, security, etc.) are very well suited to virtualization and NFV. For example, thanks to NFV/SDN: • a virtualized 4G core network could be deployed on a local server in a factory, to speed-up network’s response time. At the same time, for the factory’s IoT needs, it should be possible to support LTE-M functions from a centrally placed installation. • CSPs should be able to support “network slicing” to achieve network behavior differentiation, on-demand, and on a per- customer or per-application/use case basis. These types of abilities enabled on 4G networks are some of the guidelines that will be at the heart of 5G. Specialists foresee that NFV/SDN will play a core role in designing performant and secure 5G networks.
