La telefonía de conmutación de circuitos en declive August 13, 2011
Posted by inza in : Comunicaciones, English , trackbackLa denominada PSTN (Public Standard Telephone Network) la telefonía fija convencional tiene cada vez menos “abonados” mientras que la telefonía móvil y la telefonía IP tienen cada vez más usuarios.
Esto preocupa a los operadores y a los reguladores, que, como en el caso de la FCC - Federal Communications Commission, desean minimizar el impacto de la transición que acabe finalmente con la telefonía fija convencional. Y ello se aprecia en esta presentación.
Problem/Opportunity Addressed:
As the number of subscribers on the PSTN falls, the cost per remaining customer increases and the overall
burden of maintaining the PSTN becomes untenable. A fast transition can generate significant economic
activity and at the same time lower the total cost
- Today’s demand for communications is much broader and requires much greater bandwidth
- Cord‐cutting’ is already happening organically at impressive rates.
- Wire‐line to Wireless displacement
- IP based network replacement/substitution for fixed and mobile communications
Key Questions:
- What is the size of the PSTN transition for Service Providers?
- How can we further accelerate this transition?
Findings:
- By 2014, the United States will have fewer than 42M access lines
- Access line losses were nearly 6.6 million between 2Q09 and 2Q10, a drop of 7.3%.
- By 2014 US consumers will have 31.6 million VoIP lines accounting for 42.5% of all U.S. access lines.
- Fixed lines continue to decline; mobile is the preferred choice for voice communication.
- More than 25% of U.S. consumers aged 18 or older have already given up their voice landline for voice wiress‐only service.
