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

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

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

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).

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

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).

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

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

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

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
