Por qué compartir dinámicamente del espectro es importante para el desarrollo del sector en Latinoamérica

ESTE WEBINAR SE ENCUENTRA DISPONIBLE BAJO DEMANDA

Este webinar tratará sobre cómo las nuevas tecnologías que permiten compartir el espectro de forma dinámica y los modelos regulatorios están siendo planteados en todo el mundo con miras a incrementar la inclusión digital y acometer el masivo crecimiento de los datos a través de redes inalámbricas.

Específicamente, el webinar tratará de explicar por qué la competencia entre las tecnologías dentro del ecosistema 3GPP (2G/3G/4G y pronto la 5G) con las que están fuera de él —como pueden ser el ecosistema de bandas sin licencia incluyendo el espectro conocido como TV Whitespaces— será crítica para poder hacer viable la reducción de la brecha digital.

El despliegue de tecnologías de acceso de espectro dinámico es prácticamente inexistente en Latinoamérica, por lo que este webinar tratará sobre cómo la región puede, a través de la innovación, incrementar la oferta y disponibilidad de espectro. Este webinar, además, explorará el papel de instituciones académicas y de investigación en la región que están experimentando con tecnologías para compartir espectro, tales como License Assisted Access y LTE-U en la banda de 5 GHz.

A través de este webinar, Dynamic Spectrum Alliance (DSA) y la Agencia Nacional de Espectro (ANE) de Colombia explicarán la importancia de compartir espectro de forma dinámica, y pedirán a los diferentes reguladores que apoyen la adopción de estas prácticas en sus mercados. Esto permitirá nuevas oportunidades para la educación, salud, comercio y la entrega de servicios públicos.

DSA y ANE estarán llevando a cabo el evento Dynamic Spectrum Alliance Global Summit en Bogotá, Colombia, del 26 al 28 de april de 2016. Todos los participantes a este webinar están invitados a participar.

  1. Thank you very much for the presentation .From the point of view of implementation , do you think the use of TV White Spaces have to be coordinated between latin America countries ?

    • H Sama Nwana

      Thank you Leo, good to e-meet you. Firstly, the use of TV bands 470-690(694) MHz have to be coordinated across Latin America. Second, I will like to see digital switchover completed across Latin America even earlier than 2020. Third, some of the released frequencies should be awarded/auctioned for 4G/LTE broadband like I did in the UK. Lastly, the whitespaces in TV bands offer an opportunity for them to be licensed-exempted using TVWS-type regulations. Remember such regulations will allow for WiFi (802.11af) to be implemented in TV bands, for LTE to be implemented in TV band or for WRAN (802.22) to be implemented in TV bands.

      So yes – coordination in LATAM will be very good – and a key reason we are organising a summit in Latin Americas and the Caribbean. Please come to our conference in Bogota, Colombia. See http://www.dynamicspectrumalliance.org/global-summit/. Spread the word!

  2. Thank you very much for the presentation. Please let me introduce myself: My name is Jorge Menacho, currently working for ATT in La Paz, Bolivia. I have three questions: 1.- I would like to know what is the main difference related to spectrum management between developed countries and third world countries? 2.- What is advisable to do to reduce that difference? 3.-What would be the logical first step to get the most of WhiteSpace?

    • H Sama Nwana

      Good to e-meet you Jorge!

      This is a good question. As someone who has run spectrum policy for a developed economy (UK) and who is advising for many 3rd world countries, there are three answers I will give you. FIRST, world spectrum policy that has been developed largely benefits developed OECD/rich economies, and not necessarily developing economies. Take for example Africa – if you look at the map, you can fit in all of the USA, India, China, Argentina and Western Europe into map of Africa and there is much space left. You can see why Africa needs UHF which propagates further that higher frequencies. Regulating for accessibility (with our spectrum management) is key to developing economies – and UHF is key to it. SECOND, regulating for affordability is most key too. Go back to my slides and see the affordability of communication services from the first to the 7th Billion people: $205, $53, $23, $12, $7, $4.4 and $2.25 respectively. Do you think operators like AT&T in countries with people first and second billion where people can afford $205 and $53 per month will not build networks to cover this rich people? They will. Do you think AT&T in countries who can only afford $7, $4.4 or $2.25 will build such networks? This is part of the problem Bolivia faces as Bolivians are largely in the 4th/5th Billion, I suspect. Spectrum management for affordability is tricky – and why people like me argue for the use of TV bands to drive accessibility and affordability. THIRD, Spectrum management in 3rd world countries is hard as vendors, suppliers from developed countries just argue blindly many times to our regulators and Governments that the first world answers are right for 3rd world countries. They hate hearing counter-arguments. Spectrum management and policy for 3rd world countries should be different from developed countries.

      In answer to your second question: 1. good spectrum policy and management education as I cover in my book (see below) 2. Good training and capacity building for spectrum and competition regulators and why we are also hosting the conference in Bogota with ANE. I would like to invite you to our conference in Bogota, Colombia: http://www.dynamicspectrumalliance.org/global-summit/.

      In answer to your final question, understand the arguments for why dynamic spectrum management is important for driving up spectrum efficiency. If you put smart engineers in a room today and ask them to design a spectrum allocation/assignment approach in 2016 (not 1916!), they will arrive at a dynamic/spectrum shared solution using databases or sensing. Whitespaces (and TV Whitespaces) is just the application of such dynamic techniques in TV bands. Same techniques can be applied to other bands too.

  3. Buenos dias, somos del ente regulador de Nicaragua, y tenemos 2 preguntas:
    1-Que banda de guarda se puede considerar para los espacios en blanco en la banda de TV digital?
    2-Podrian facilitarnos los enlaces web, del estudio de McKinsey y el documento de estudio de colombia

    • Rafael A. Junquera

      Traduzco para H.

      Good morning, we are from the Nicaraguan regulator and we have 2 questions:
      1. Which guard band can be considered for TV White Spaces on the digital TV band?
      2. Could you share with us the links to the McKinsey study and the document about the study in Colombia

    • H Sama Nwana

      Good to e-meet you Alma. You must come to the DSA Global Summit in Bogota, Colombia, please see http://www.dynamicspectrumalliance.org/global-summit/.

      In answer to your first question Alma, this is a slightly tricky question. It depends obviously on what you are “guarding”! Remember, TVWS rules allow for secondary use of a band whilst protecting the primary user. In the TV bands, the primary user is clearly TV. In the original USA/FCC TVWS rules of 2012, they decided that they would NOT allow a TVWS device to operate in a UHF frequency adjacent to a TV frequency being used, i.e. they forced a guard band. Ofcom UK found that TVWS devices can operate in adjacent frequencies, and USA/FCC has since proposed new rules in Aug 2015. It also depends on power, etc. Come to Bogota to hear more from me and others!

  4. Buenos dias,
    – En que año se podria contar con aplicaciones comerciales para TVWS
    – Desde el punto de vista del regulador cuales podrian ser los pasos para incentivar TVWS

  5. Buen día.
    En relación a la última diapositiva que muestra el uso de las bandas de frecuencias

    ¿Cuál es la experiencia actual y las previsiones futuras respecto a la convivencia de los sistemas ICM (aplicaciones Industriales, Científicas y Médicas) que no necesitan licenciamiento con las bandas de frecuencias licenciadas?

    Como ejemplo podemos mencionar los sistemas de baja propagación (RFID) que trabajan en la banda 902-928 MHz sobreponiéndose con la banda licenciada.

    • Rafael A. Junquera

      Translation for H.
      Good Morning.
      About the last slide that shows the usage of frequency bands:
      Which is the current examples and the future regarding the coexistance of ICM systems (Industrial, Scientific and Medical applications) that do not requiere a license with the licensed frequency bands?

      As an example we could mention low propagation systems (RFID) that work in the 902-928 band overlaying with licensed bands.

  6. For H, from Chile:
    Can you talk about the governance for Dynamic Spectrum Access, since there is a common database needed, how are implementation investment shared in the industry.

    • H Sama Nwana

      Hello, good to e-meet you Daniel. You must come to the DSA Global Summit in Bogota, Colombia as this is a deep question. http://www.dynamicspectrumalliance.org/global-summit/

      The governance can be summarised as follows:

      1. The Base station sends its GPS location to a database.
      2. The database compares it to a list of TV stations in the area.
      3. An approved vacant channel list is returned and power limit
      4. The base station uses and channel and the power limit
      5. Easy in the age of cognitive radios.

      You can have several commercial databases who provide competing services and companies who use them will pay for their services is a short answer. We can meet to have a much longer answer?

  7. Buenos días quisiera saber si hay muchas bandas por asignar, porque no vuelven a abrir frecuencia para Radio y TV radiado, un tercer operador Privado.

    • Rafael A. Junquera

      Translation for H.

      Good morning, I would like to know if there are many bands to be assigned, and why there aren’t more TV and Radio bands to assigned a third private operator.

      (Marco, no entendí muy bien la parte final, si la traducción te parece que no está muy bien, me avisas)

    • H Sama Nwana

      Wow – which country are you from Marco? It depends on the countries. First the use of TV bands 470-690(694) MHz have to be coordinated across Latin America. Second, I will like to see digital switchover completed across Latin America even earlier than 2020. Third, some of the released frequencies should be awarded/auctioned for 4G/LTE broadband like I did in the UK. So release for 3rd operator perhaps. Lastly, the whitespaces in TV bands offer an opportunity for them to be licensed-exempted using TVWS-type regulations. Remember such regulations will allow for WiFi (802.11af) to be implemented in TV bands, for LTE to be implemented in TV band or for WRAN (802.22) to be implemented in TV bands.

      Please come to our conference in Bogota, Colombia. See http://www.dynamicspectrumalliance.org/global-summit/.

  8. Hola H
    Qué opinas de que en América latina la utilización de los espacios en blanco constituyen un tema regulatorio mas que meramente técnico.

    • Rafael A. Junquera

      For H,

      Hi H,
      What do you think about the fact that the use of TV White Spaces it is more about regulation than technical aspects?

    • H Sama Nwana

      Hello, good to e-meet you Hayser.

      Wow – what a great question! The biggest issue is regulation and policy – you are right. Changing the culture of regulation and policy is as difficult as changing culture in all other aspects of life but it can be overcome by 1. Good spectrum policy and management education. 2. Good training and capacity building for spectrum and competition regulators and why we are also doing the conference in Bogota with ANE.

      Please come to our Global Summit in Bogota, Colombia. See http://www.dynamicspectrumalliance.org/global-summit/.

      • hi H.
        I appreciate your comments, radio spectrum is manageable with government policies, defined and appropriate regional best practices and development of technologies. the big problem is to define those good practices and set of priorities. I believe that each country must set its priorities without neglecting regional progress and determine the economic cost, impact and time of application of their policies regarding the use of radio spectrum.

        regards

        Hayser
