1 Dynamic Spectrum Access & Sharing: a DSA Viewpoint Prof. H Sama Nwana, Executive Director DSA Global Summit, Manila, Philippines 7 th May 2015

2 Dynamic Spectrum Alliance A global, cross-industry alliance focused on increasing dynamic access to unused radio frequencies Goals: Closing the Digital Divide Enabling the Internet of Things Alleviating the Spectrum Crunch 2015 Dynamic Spectrum Alliance 2

3 About the Dynamic Spectrum Alliance The Dynamic Spectrum Alliance is a global organization advocating for laws and regulations that will lead to more efficient and effective spectrum utilization. The Dynamic Spectrum Alliance members are working to create innovative solutions that will increase the amount of available spectrum to the benefit of consumers and businesses alike. The Dynamic Spectrum Alliance has developed model rules that can be used by regulators in adopting license-exempt rules for TV white space access. Available at: Dynamic Spectrum Alliance 3

4 Key Executive Summary Messages 1. Dynamic spectrum access and Spectrum Sharing is a no brainer and increasingly being seen as such by leading regulators 2. Markets move faster than [spectrum] regulation, coupled with an ever growing demand for spectrum We need to move on to different models of spectrum regulation which reflects this dynamic reality Hence [1] dynamic spectrum access regulations [2] spectrum sharing must increasingly be the norm. 3. Asia is home to a significant part of the 4.4 Billion broadbandunconnected (ITU: end 2013) and dynamic spectrum access and sharing techniques will play a key role in connecting them. So in Africa and Latin America too Dynamic Spectrum Alliance 4

5 Key Executive Summary Messages Dynamic spectrum access and spectrum sharing is on the cusp of enabling an alternative and complementary ecosystem to the current 3GPP ecosystem to help drive more accessible and affordable voice and broadband services in places like the Philippines, Asia and elsewhere unlicensed Wi-Fi is key 5. We must not be scared and/or underestimate what licenseexempt access can enable but we also respectfully acknowledge the great contributions being made by the licensed ecosystem today 6. DSA s interest and work spans much than TVWS: 3.5GHz, unlicensed at 5Ghz and 2.4GHz, MHz, IoT/M2M, 5G & DSA, dynamic spectrum rules/standards, GSM Whitespaces, etc Dynamic Spectrum Alliance 5

6 Key Executive Summary Messages There are other spectrum bands wherein the only way forward is spectrum sharing, e.g. 3.5GHz in Europe/USA and dynamic spectrum sharing techniques are already being considered for these bands, e.g. geo-databases and/or sensing 8. The ITU is not stopping (you) regulators from implementing dynamic spectrum access and sharing regulations. It is up to national regulators to decide what is right for them. 9. DSA s goals are truly simple so join us as long as you believe in them or want to keep a watching brief on dynamic spectrum access/sharing. We are open (and inclusive) the DSA Community Portal 2015 Dynamic Spectrum Alliance 6

7 Why did the DSA Board choose the Philippines for this Global Summit?

8 Why Manila? Why Philippines? DSA members have been heavily involved in the Philippines ever since the first live TV white spaces demo was demonstrated in the Philippines three years ago at the Asian Development Bank annual meetings in Manila Involved ADB, Microsoft, Adaptrum, and the Philippine ICT Office Positive regulation movement and cooperative co-hosts (NTC & ICTO) Asian Development bank has supported TVWS trials TVWS regulations released for public comment at the end of to help influence policy: Dynamic Spectrum Alliance Letter on Philippine Memorandum Circular February 2015 Dynamic Spectrum Alliance Response to NTC's Draft Memorandum Circular- December Dynamic Spectrum Alliance 8

9 The Philippines Internet Landscape 2015 Dynamic Spectrum Alliance 9

10 Why Philippines? 7107 islands! Over 50% of Filipinos under 25! 51% rural; 49% urban (source World Bank) Philippines has been known as the texting capital of the world and the social media capital of the world at various times over last few years (GSMA Intelligence, 2014) Though Philippines has 105M (i.e. 105%) mobile subs (2014) - ONLY over 7M mobile broadband subs by early 2014, i.e. only 7% of the population 40M+ internet users Fixed line market is in low single % digits So GSMA recommends a key area for Govt investment is digital inclusion => strong drivers for DSA and TVWS 2015 Dynamic Spectrum Alliance 10

11 Free Wi-Fi Accelerating Inclusive Growth

12 Summary Progress since last Global Summit

13 Summary Progress since/from last summit in Ghana in May 2014 Progress since the last Summit in May 2014 (Ghana) 1. Publication of TVWS Model Rules 2. Engagement with ITU-D, ATU and a 15+ regulators 3. Members new trials and commercial deployments 4. Growing membership Added 9 new members in past 12 months We encourage you to join today! 5. Website updates and new Community Portal Regulatory Submissions 2015 Dynamic Spectrum Alliance 13

14 Why Dynamic Spectrum Access and sharing? Some Examples

15 Key Spectrum Policy Process Elements are just getting too hard/un-dynamic Re-assignment (of rights) of spectrum is painful and long Spectrum clearances, e.g. Channels 61, 62 and 69 in UK OR UK Radars in GHz took dozens of millions of s sterling Market-based mechanisms are hard too: ref Incentive auctions in USA DSO took 15+ years typically from inception to spectrum awards Re-allocations (via auctions or assignments or beauty contests) are Hard and protracted (sometimes) Releasing Government spectrum to awards is just painful too Authorisations, Products & Licensing Time consuming and resource hungry and getting harder with more products, bands, models 2015 Dynamic Spectrum Alliance 16

16 On change of use of broadcast spectrum to close the Digital Divide: e.g. Africa No brainer Africa needs to use its UHF spectrum for broadband coverage TVWS-tests completed in Accra, showing no interference when transmitting on a channel between two live TV channels. Also vast swathes of GSM whitespaces too! Key implications?

17 There is lots of channels free UHF TV across Africa, Philippines & Asia too Figure 39 UHF Assignments in Malawi as of May 2013 Source: Malawi Communications Regulatory Authority (MACRA) 18

18 Dynamic Spectrum Access What is it? A spectrum sharing approach that allows secondary users to access the abundant spectrum holes or white spaces in licensed spectrum bands DSA technology enables radios to safely share multiple frequency bands without interfering with legacy and other protected wireless systems White Space = part of the spectrum, available for a radiocommunication application (service, system) at a given time in a given geographical area on a non-interfering/non-protected basis with regard to primary and other services (CEPT Report 24, 2008)

19 Seeing through the lens of a spectrum analyser 470 MHz 854 MHz (8 MHz TV channels): Analogue TV, Digital TV and White spaces

20 Spectrum Sharing Update (2015): Unlicensed in the TV Bands

21 Spectrum Sharing: Unlicensed in Wi-Fi bands 51% (Singapore), 63% (USA), 68% (Hong Kong) and 82% (Spain) data off-loading to Wi-Fi from smartphones EBU estimates that 71% of all wireless data to mobile devices in the EU was delivered using Wi-Fi in 2014 Without Wi-Fi offload, mobile data traffic would have grown 98% rather than 81% in % will be offloaded by 2020!! So Wi-Fi/license-exempt complements licensed Key reason for opening up for 5GHz spectrum for Wi-Fi 22 sharing and for Wi-Fi in TV bands: af, and ah

22 3.5 GHz Spectrum Access Tiers (USA) Incumbent Access Priority Access General Authorized Access Incumbent Access: Includes authorized federal and grandfathered Fixed Satellite Service (FSS) users currently operating in the 3.5 GHz Band. Priority Access: Authorize certain users to operate with some interference protection in portions of the 3.5 GHz Band at specific locations General Authorized Access: Users would be authorized to use the 3.5 GHz Band opportunistically within designated geographic areas. GAA users would be required to accept interference from Incumbent and Priority Access tier users.

23 GSM Whitespaces

24 Why GSM Whitespaces? Cellular Networks have stopped expanding their reach 3.5 Billion people on cellular network 1 Billion people living outside of cellular coverage

25 because traditional infrastructure and operating costs are too high (source Endaga) Equipment Urban (Cost) Rural (Cost) GSM Access Point Low Low Mount Low (Roof) High (Tower) Backhaul Low (Wired) High (Carrier-grade Microwave) Power Low (Grid) High (Diesel) Fence None (Roof) High (Protect Diesel) Road/Transport None (Existing) High (Rough Roads) Total $ $$$$

26 Local Ownership Model (source Endaga) Equipment Traditional (Cost) Local (Cost) GSM Access Point Medium (Huawei) Low (Endaga) Mount High (Tower) None (Roof or Tree) Backhaul High (Carrier Microwave) Low (Consumer vsat) Power High (Diesel) Low (Local or Solar) Fence High (Protect Diesel) None (On owner property) Road/Transport High (Bad Roads) None (Local Transport) Total $150, ,000 $10,000

27 Solution: Locally Owned Cellular/Mobile Networks i. can lease spectrum from MNOs or ii. can seek access to unused GSM spectrum from the regulator and use dynamic access techniques

28 Papua, Indonesia (source: Endaga) Location: 4 hours drive from nearest traditional cellular coverage Network Live in February Subscribers Run by local primary school Interconnects to major national carrier

29 Some Spectrum Crunch Areas DSA would be or - is exploring DSA/Sharing in 3.5GHz band Unlicensed sharing in TVWS 5GHz MHz LSA in 2.4Ghz, 3.5GHz GSM Whitespaces Standards: ETSI PAWS, af, , 802.ah, etc IoT/M2M Geolocation Sharing in GHz (FS & FSS sharing) 5G & DSA 2015 Dynamic Spectrum Alliance 35

30 Regulators can move forward with enabling legislation and/or regulations... The ITU World Radiocommunication Conference of 2012 concluded that the current international regulatory framework can accommodate software defined radio and cognitive radio systems, hence dynamic spectrum access, without being changed. The development of systems implementing this concept, such as TV white spaces, is therefore essentially in the hands of national regulators in each country..for this, regulators will depend on state of the art best practices which are currently developed by ITU-R Study Groups 1, 5 and 6.

31 Worldwide Pilot Projects and Trials Dynamic Spectrum Alliance 37

32 Exec Director 2015/2016 Call to Action Call on DSA/TVWS ecosystem development and bigger deployments to help drive ecosystem E.g. Economics of base stations/cpes, etc need volume orders to costs down to levels that will accommodate $2-5 per monthly broadband costs Need to create a virtuous circle of regulations driving ecosystem which further drives more countries to move on DSA regulations`, etc Dynamic Spectrum Alliance 38
