1990

1980

1G analogue systems provided two key

improvements over the first radiotelephone

services:

- the invention of the microprocessor; and

- digitization of the control link between the

mobile phone and the cell site.

1970s

Frequencies for mobile services allocated in the Radio Regulations

First Generation (1G)

2G systems digitized not only the control link

but also the voice signal - better quality and

higher capacity at lower cost.

Regional/global operation was hampered by:

- multiple incompatible standards;

- different frequency bands and channels

in different parts of the world.

1980s-1990s

ITU-R develops the international mobile telecommunication system (IMT) to address these issues – first global IMT frequencies identified at WRC-92

Second Generation (2G)

ITU’s IMT-2000 global standard for 3G unanimously approved at the ITU Radiocommunication Assembly 2000 – digital voice and data. Global standard and harmonized frequencies: - global roaming; - massive economies of scale; - innovative applications and services.

2000s

WRC-2000 and WRC-07 identified additional frequency bands for IMT in the Radio Regulations

IMT-2000 – Third Generation (3G)

IMT-Advanced specifications approved at the ITU Radiocommunication Assembly 2012 - packet-based, multi-media, high data rates. Mobile broadband becomes the main method of accessing the Internet

2010s

WRC-15 harmonized and identified additional frequency bands for IMT in the Radio Regulations

IMT-Advanced – Fourth Generation (4G)

IMT-2020 specifications scheduled for

completion in 2020:

- Gigabit data rates and enhanced

performance for mobile broadband

- Support for billions of smart devices

- Responsive and ultra-reliable

communications for mission critical

applications

2020s

WRC-19 identified frequencies above 24 GHz for IMT in the Radio Regulations

Enhanced Mobile Broadband

Massive Machine Type Communications

Ultra-reliable and Low Latency Communications

3D video, UHD screens

Smart City

Industry automation

- IMT: Devised within ITU through the work of ITU Study Groups (worldwide participation, amongst all stakeholders: Regional Organizations, Regulators, operators, manufactures, universities and R&D Centers,, etc.) Unique set of Definitions and Specifications (through ITU-R publications) - xG: Devised by operators and mobile community. There is no unique set of definitions.

___________________________________ - IMT-2000 and 3G: there was consensus about matching both these concepts and

associated specifications. - IMT-Advanced and 4G: no global consensus was reached: • Some Regulators demand that a 4G brand must comply with IMT-Advanced

specifications (thus the branding: 3.5G, 3.75G, etc.) • Other Regulators recognize 4G as those technologies providing an enhanced

performance in comparison to IMT-2000 Specifications. ___________________________________

Broadband Networks

Broadband services require an infrastructure of networks. 3 types of final access (last km, last mile): - Fixed: copper, coaxial, fiber - Wireless (Terrestrial): cellular, Wi-Fi? - Satellite Broadband penetration is topped by the penetration of these networks

- Fixed Networks in slight decline - Mobile Networks in high growth, near saturation - increasing Gap between developed and developing world. - Broadband Universal Service in developing world: Mobile & Prepaid

Broadband Access: Fixed vs. Mobile

5G in Developing Countries • It will undoubtedly happen, and quite rapidly once it starts. • 5G deployment part is of a much bigger issue – connecting

the unconnected and bridging the digital divide. • Coverage versus speed trade-off reflects a larger debate

about social objectives versus ‘cherry-picking’ profitable areas.

• Need a viable commercial business case going forward for 5G deployments to happen in most optimal way.

5G in the developing world

What can 5G do for developing countries

• Directly increasing GDP • Greater economic growth or % gain in GDP

• Reducing transaction costs

• Better, faster, more informed decision-making

• Boosting labour productivity

• Resulting in a net gain in jobs

RADIO REGULATIONS: KEY DEFINITIONS

RR, No. 1.19 Radiocommunication service: A service involving the transmission, emission and/or reception of radio waves for specific telecommunication purposes.

RR, No. 1.61 Station: One or more transmitters or receivers or a combination of transmitters and receivers, including the accessory equipment, necessary at one location for carrying on a radiocommunication service, or the radio astronomy service

RR, No. 1.16 allocation (of a frequency band): Entry in the Table of Frequency Allocations* of a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions. This term shall also be applied to the frequency band concerned.

RR, No. 1.17 allotment (of a radio frequency or radio frequency channel): Entry of a designated frequency channel in an agreed plan, adopted by a competent conference, for use by one or more administrations for a terrestrial or space radiocommunication service in one or more identified countries or geographical areas and under specified conditions.

RR 1.18 assignment (of a radio frequency or radio frequency channel): Authorization given by an administration for a radio station to use a radio frequency or radio frequency channel under specified conditions.

Allocations are granted to Radiocommunications Services

Assignments are granted to Radiocommunications Stations

RADIO REGULATIONS PRINCIPLES

RR is technically neutral*, hence, it

1. Does allocate frequency bands to radiocommunication services

2. Does not allocate to specific applications

3. Does not allocate to particular technologies

4. Does not define users profile (official, commercial, private, etc.)

e.g.: allocation can be made to: “mobile” (service; by default: terrestrial, land)

- not specifically to :

a) cellular networks (application)

b) GMS, LTE, Wimax, etc. (technology)

c) Official/commercial/particular use

* NTFAs might go further (applications, technologies, profile, etc.) while being consistent with the RR TFA; Example: Mobile for IMT, official use, etc.

Radio Regulations; World Regions

RR: Table of Frequency Allocations

5.25 a) services the names of which are printed in “capitals” (example: FIXED); these are called “primary”

services;

5.26 b) services the names of which are printed in “normal characters” (example: Mobile); these are called

“secondary” services (see Nos. 5.28 to 5.31).

5.48 3) Within each of the categories specified in Nos. 5.25 and 5.26, services are listed in alphabetical

order according to the French language. The order of listing does not indicate relative priority within

each category.

5.50 5) The footnote references which appear in the Table below the allocated service or services apply to

more than one of the allocated services, or to the whole of the allocation concerned.

5.51 6) The footnote references which appear to the right of the name of a service are applicable only to

that particular service.

CATEGORY OF SERVICE

Category of Services (basis) might be in a:

- a) PRIMARY basis (indicated by capital letters)*; e.g.: FIXED

- b) Secondary basis (indicated by lower case); e.g.: Fixed

RR, No. 5.28 Stations of a secondary service:

RR, No. 5.29 a) shall not cause harmful interference to stations of primary services to which frequencies are already assigned or to which frequencies may be assigned at a later date;

RR, No..30 b) cannot claim protection from harmful interference from stations of a primary service to which frequencies are already assigned or may be assigned at a later date;

RR, No. 5.31 c) can claim protection, however, from harmful interference from stations of the same or other secondary service(s) to which frequencies may be assigned at a later date**

(**first in time, first in right)

RADIO REGULATIONS

Other concepts: although not explicitly defined, on the RR when dealing with band allocations (Art. 5), the use into footnotes of expressions: “identified” and “designated” express the interest/intention of some administrations on a future use of that band for a specific application; that in benefit of a mid and long term harmonization of the use of that band. Examples*:

RR, Nos. 5.138, 5.150, 5.280 (some R1): Bands designated for industrial, scientific and medical (ISM) applications.

RR, No. 5.552A: Bands designated for use by high Altitude Platform Stations (HAPS)

RR, No. 5.516B: bands identified* for use by High-Density applications in the fixed-satellite service (also named: High Througput Satellites, HTS)

RR, Nos. 5.286AA, 5.313.A, 5.317A, …………, etc.: Bands identified* for International Mobile Telecommunications (IMT)

NO allocations to IMT on the main Table; but Identifications through footnotes

Identification for IMT at large (no specific version) : on bands with MOBILE allocation

Stating that: “This identification does not preclude the use of this band by any application of the services to which it is allocated and does not establish priority in the Radio Regulations”.
