License-Exempt Wireless Policy: Results of an African Survey Isabel Neto Sharon E. Gillett & Michael L. Best ITS conference, Berlin 7th September 2004 Wireless technology can be used to achieve connectivity at different levels Source: ‘The Wireless revolution and Universal Access’, Michael Best, Trends in Telecommunications Reform 2003, ITU, Chapter 7 | 2.4 & 5GHz Bands Low cost, especially for localized coverage Standards available for different levels (802.11b, 802.16, etc) Combinations with other technology possible (e.g. VSAT, etc) Different solutions for end-user equipment: laptops, WiFi phones, asynchronous reception models, etc Isabel Neto, ITS, 7th Sept 2004 Motivation Changing nature of technology (e.g. spread spectrum) and spectrum management Growing use of unlicensed bands: 2.4 and 5GHz Band – Institutions and the developing world context Corruption, inefficiencies, obstacles – Entrepreneurship Value of bottom-up approaches Unlicensed bands as friendly environment for entrepreneurs – – Hypothesis: Unlicensed bands can spur entrepreneurship solutions and enhance connectivity Very little information available on regulation, use and best practice notes – ITU (limited info), US State Depart. (confidential), W2i conf. ‘03 | Isabel Neto, ITS, 7th Sept 2004 Methodology: the survey Survey covering: 1. 2. 3. Sent to all African countries (54 countries): – – Regulators Other people who work in ICT sector (e.g. ISPs) Distribution via e-mail (total of ~260 e-mails sent) – Spectrum licensing / enforcement on 2.4 & 5GHz Bands Background to regulations Implementation and experiences of use reminders, contact by phone All contacts in French, Portuguese and English | Isabel Neto, ITS, 7th Sept 2004 Level of response 70% Share of Surveys 60% 50% 40% Sent 30% Received 20% 10% 0% Regulators & ministries, from ITU Carriers & industry associations, from ITU Users & ISPs, from personal contacts Responses obtained mainly from regulators Results by population: 96% response rate | Isabel Neto, ITS, 7th Sept 2004 Difficulties & delays Countries Response Lag From ~260 contacts 20% unreachable 35% response to e-mail 20% response to survey 46 43 40 37 34 31 28 25 22 19 16 13 10 7 4 1 0 10 20 30 40 50 60 70 80 90 Days Need to account for connectivity and other problems People very cooperative | Isabel Neto, ITS, 7th Sept 2004 Key findings Uncertain and heterogeneous environment – – – Significant variation in rules (‘unlicensed’ has several meanings, technical restrictions, other business restrictions) Creates confusion and discourages small players Deters bigger players because no economies of scale Still, bands being used everywhere, both for localized and surprisingly high for wider area coverage | Isabel Neto, ITS, 7th Sept 2004 Licensing regimes 2.4GHz Band 5GHz Band | Isabel Neto, ITS, 7th Sept 2004 Licensing regimes (cont.) Detailed Licensing Regimes by country, 2.4GHz Band Around 50% licensed (mostly automatic) Most unlicensed requires a registration: unlicensed, as known in e.g. US, almost nonexistent Generally 5GHz band more restrictive (newer technology) No regulation or regulator, 4, 7% Unlicensed, no registration, 3, 6% Not avalable, 7, 13% Use barred, 1, 2% Licensed, not automatic, 7, 13% Unlicensed, registration, 10, 19% Licensed, automatic, 22, 40% 2.4GHz Band | Isabel Neto, ITS, 7th Sept 2004 Differences surprising, given sources Background to regulations by licensing type 16 Number of countries 14 12 ITU CEPT/ERC 10 ETSI 8 FCC other countries 6 others (e.g. SADC) 4 own only 2 0 Unlicensed, no registration Unlicensed, registration Licensed, automatic Licensed, not automatic Highlights ITU’s harmonization role: regulation somewhat vague in these bands | Isabel Neto, ITS, 7th Sept 2004 Heterogeneity and uncertainty Mali: no regulation in place Eritrea: free use for incumbents, ISPs pay a fee Botswana: automatic, but ISPs need to be registered in country and present business plan Namibia: unlicensed, but only allowed within property boundaries South Africa, Mauritius: unlicensed within single premises, licensed between premises Mozambique: Only for non commercial purposes Regulation undergoing changes, and sometimes uncertain Additional parameters: Power/range/services restrictions, certification, etc | Isabel Neto, ITS, 7th Sept 2004 Other dimensions: technical restrictions More restrictions imposed on ‘laxer’ licensing regimes Correlation w/ indicators: lower competition in local & long distance markets => more restrictions on power & range Power restrictions EIRP [W] Averages of allowable Power and Range levels for 2.4GHz Not 4.0 limited Range restrictions >= 3.0 4 Not limited Outdoors, long range (>1km) [ 1,2.0 4[ Outdoors, short range (<1km) [ 0.1,1.0 1[ < 0.1 0.0 Indoors only Unlicensed, no registration Unlicensed, registration Licensed, automatic Licensed, not automatic Restrictions in bands may be used to control market power and raise barriers to entry | Isabel Neto, ITS, 7th Sept 2004 Power Range Certification requirements also differs across countries Two opposite and combined effects? 2. Laxer licensing regimes as consequence of regulators ‘washing their hands’ => leading to less certification Regulators may choose to certify equipment to have some control over interference (since bands often regulated on a ‘best-effort’ or ‘no QoS guarantee’ basis). Percentage of countries in different categories 1. Certification vs. 2.4GHz licensing regime 100% 90% 80% 70% 60% Not Certified 50% Certified 40% 30% 20% 10% 0% No regulation Unlicensed, no Unlicensed, registration registration | Licensed, automatic Isabel Neto, ITS, 7th Sept 2004 Licensed, not automatic Services restrictions: e.g., voice (VoIP) may not be allowed Are there restrictions in the services to be used in this band? (2.4 GHz) | Isabel Neto, ITS, 7th Sept 2004 Low enforcement & capacity to enforce • Enforcement likely to be even lower, since most responses from regulators • Reports of significant illegal use | Isabel Neto, ITS, 7th Sept 2004 Despite this…. Ubiquity of use Significant use, given context More use in 2.4GHz (5GHz newer) Main users ISPs (56%), followed by Telecom operators (28%) | Isabel Neto, ITS, 7th Sept 2004 Bands used mainly for localized but also wider area coverage Percentage of countries in licensed/unlicensed bands Use of spectrum for 2.4 Licensed and unlicensed bands 90% 80% 70% Localized coverage, urban hotspots 60% Rural connectivity, wider area coverage (infrastructure, point to point, point-to-multipoint) 50% 40% Other (e.g., private networks, interconnection betw sites, grey market) 30% 20% 10% 0% unlicensed 2.4 spectrum licensed 2.4 spectrum Relatively more countries deploying wider area networks in licensed environments Technical restrictions imposed may explain this difference | Isabel Neto, ITS, 7th Sept 2004 Recommendations Seek to harmonize policies across the continent Establish better business environment (e.g. UService policies) Aim for more balanced regulatory models – – Now, regulatory regimes tending to over regulate – protecting incumbents? Err on the side of laxity | Isabel Neto, ITS, 7th Sept 2004 A key role for regional bodies? Objective: Rapid harmonization of spectrum policies that are: • good for the continent • integrate well into international context: Several bodies active in ICT policy: – – Economic Commission of West African States (ECOWAS) created the West African Telecommunications Regulatory Association (WATRA). South African Development Community (SADC) made good progress through their Telecommunications Regulators Association of Southern Africa (TRASA). NEPAD (New Partnership for Africa's Development) could play key role by liasing with those regional bodies, the ITU, and other regulators (e.g. FCC, ECC, etc). | Isabel Neto, ITS, 7th Sept 2004 Seek to establish better business environment Are there Universal Service Policies for use in these bands? Certainty and stability Lower barriers to entry Access to capital Universal Service Policies? Universal Service Policies are still and untapped opportunity | Isabel Neto, ITS, 7th Sept 2004 Right balance needed Type of restriction Advantages Disadvantages Unlicensed bands - Lower barriers to entry, promoting competition in the market - Avoid regulatory capture, in particular in concentrated markets - Lower guarantees - More difficult to manage interference - More revenue for the government Low restrictions on power & range - Enables wider area coverage, increasing population covered - Higher competition in the long distance market - Encourage innovation and experimentation - Levels of interference can rise - Bands may become congested and unusable Certification required - Ensures quality and reduces interference - Discourages innovation and experimentation Services restricted (e.g. no voice allowed) - Good for incumbent and traditional telecom companies (can have monopoly over voice) - Bad for users, there will be less competition in the market for those services Strict Enforcement - If regulations are set at an appropriate level, enforcement is good, since it will control interference and punish offenders, ensuring the well functioning of the bands - Can be a form of capture if restrictions are set too high | Isabel Neto, ITS, 7th Sept 2004 Err on the side of laxity?... The objective should be to maximize output – i.e., connectivity may come at the cost of some interference Spectrum is renewable resource (unlike fish, or forests) Africa has very weak teledensity – going from ‘no service’ to ‘SOME service’?... Need to lower barriers to entry Since little use, lower probability for congestion | Isabel Neto, ITS, 7th Sept 2004 Suggestions for further research More info on use – – Look at amount of use (e.g. talk to suppliers, operators) Cross users with type of use (e.g. who is doing rural coverage?) Develop country categories and select case studies Look further for reasons why spectrum policies differ in different countries Work on specific recommendations to improve regulatory balance Further look into enabling business environment | Isabel Neto, ITS, 7th Sept 2004 Thank you!
