5 Industry Activity on 5G (1/3) Samsung Providing Gigabit Experience to Users Anywhere with Latency<1ms 5G enablers: mmwave System Technology Advanced small Cell Device to Device communication Advanced MIMO Advanced interference management Samsung Experimental Results: 28GHz range, using adaptive beamforming with range of 2KM. Test Results: Outdoor Line-of-Sight (LoS) Range Test, upto 2Km at Line of Sight : Speed 1Gbps Outdoor Non-Line-of-Sight (NLoS) Mobility Tests - upto 528Mbps 5

6 Industry Activity on 5G (2/3) Nokia Aiming at Virtually zero latency Up to 10Gbps speed 5G enablers: Use of Cloud in telecom network Advanced spectrum sharing techniques-nokia has carried out tests in Authorized Shared Access (ASA) in LTE TDD 2.3GHz band with TEKES. Higher frequency bands: Use of GHz band may be used in backhaul as well as in access 6

7 Industry Activity on 5G (3/3) Some Other Projects METIS: A EU FP7 program, has derived a number of specific requirements from scenario, like: Ten to one hundred times higher typical user data rate, end-to-end latency will be less than 5 ms with high reliability etc. Wireless@MIT: Is researching topics like spectrum crisis, power consumption with industry. Tokyo Institute of Technology and DOCOMO: Conducted trial in 11GHZ spectrum and has achieved 10Gbps data rate. China s Ministry of Industry and Information Technology has established a working group called IMT (5G) Promotion Group for 5G research in February

8 Emerging Picture and Prospective Technologies (1/6) From the ongoing projects, it can be concluded that main activity of the Industry are focused inter alia on the following : 1) Millimeter Wave 2) Dynamic Spectrum Access 3) Mobile Content Delivery Optimisation 4) C-RAN 5) SDN and NFV 8

9 Emerging Picture and Prospective Technologies Millimeter Wave (2/6) At the radio side, millimeter waves (mmw) are being considered for : Small cell backhaul - wireless backhaul appears to be a better and affordable solution than fiber for the complex mix of small-cell locations WiFi hotspots -In WiFi hotspots, the unlicensed 60GHz mmw band can be used to escape the crowded 2.4GHz ISM band and to provide gigabit rate data transfer. Two standards in this band are: Wireless HD which targets WPAN, Part of , with data transfer speed>1gbps IEEE ad: with data transfer speed>7gbps. Radio Interface: Use of mmw in Radio Access Network 9

10 Emerging Picture and Prospective Technologies Dynamic Spectrum Access (3/6) To support next generation applications, operators will require more spectrum. Since spectrum is a scarce resource, methods like Dynamic Spectrum Access (DSA) are being explored. DSA was implemented using Software Defined Radio Geolocation Database-Here, a central database informs device of the frequencies and the operating conditions. DSA is a important approach that is being considered by regulators in some countries. 10

11 Emerging Picture and Prospective Technologies Mobile Content Delivery Optimization (4/6) The increasing amount of data being consumed by mobile users puts a huge stress on the backhaul which has to support the peak traffic and many moves eg.-caching at cell site, have been undertaken to handle the traffic efficiently. Proprietary solutions cause problems in integration. Industry groups are now focusing on standardization of Mobile Content Delivery Optimization, developing use cases and requirements like caching and media adaptation taking into account the - characteristics of the network/the node sadditional nodes required, protocol between them interface to existing network entities. 3GPP Release 13 Study items include Study on Application specific Congestion control for Data Communication. 11

12 Emerging Picture and Prospective Technologies C-RAN (Cloud RAN) (5/6) An efficient way of deploying small cells could be to separate the base station functionality into two- the distributed remote radio units (RU) the digital unit (DU) or BaseBand Unit and connecting the two using low latency, high bandwidth transport network. The above concept is already available in existing technologies. The DUs can be implemented as a cloud providing centralized resource aggregation and pooling. This architecture is known as the C-RAN or Cloud RAN. Because of the Centralized processing, implementing CoMP (Coordinated Multi Point), eicic (enhanced Inter Cell Interference Coordination) for the small cells is also easier. As C-RAN is based on the cloud, Virtualisation can also be added to it. 12

13 Emerging Picture and Prospective Technologies SDN and NFV (6/6) SDN refers to the decoupling of the control plane and the data plane and the availability of central network control which enables network programmability through open APIs. OpenFlow is the most prominent SDN protocol today. SDN is important as it can enable easy modification of features of routers and switches. Continued. 13

14 Network Function Virtualization involves implementing network functions in software that can run on a range of industry standard server hardware, and that can be moved to, or instantiated in, various locations in the network as required, without the need to install new equipment. It creates more efficiency to deliver service to the end user by decoupling software from hardware and achieving gains from cloud computing. This technology could provide significant benefits for network operators and their customers: Reduced operator CAPEX and OPEX through reduced equipment costs and reduced power consumption Reduced time-to-market to deploy new network services Improved return on investment from new services 14

15 Government Perspective (1/2) Govt is actively participating in relevant ITU-R forum where identification of new bands for IMT technologies are being handled. Currently, the spectrum auctioned in India is liberalized spectrum which enables easier deployment of new technologies. As and when new bands are identified by WRC, further action for making available new bands will be required. Unlicensing of more spectrum bands for WiFi/Hotspot operation may become necessary. 15

16 Government Perspective (2/2) Keeping in view large scale deployment of small cells in future, National Building Code may need to be modified to include provision for creation of telecom infrastructure including in-building solutions at the time of building construction. State Govt./Local bodies need to create enabling framework for deployment of new technologies like small cells/hotspots in public places. Industry/academia needs to come forward to undertake research, create IPRs, enhance manufacturing in India in respect of emerging technologies/standards. 16
