4. MARCO TEÓRICO

4.1. Criterios para el análisis de materiales didácticos

In December 2015 there were 3.5 million fixed telephony subscriptions in Sweden, which can be compared to 3.7 million in December 2014. This corresponds to a continued decline of 5 per cent.

Figure 9 Number of fixed call services subscriptions

Of the fixed subscriptions, approximately 2.6 million were private, which is a decrease of 7 per cent. The number of fixed corporate subscriptions amounted to 900,000. Corporate subscriptions have declined since 2005, but are now showing an unexpected increase of 3 per cent. Telia decreased by 81,000, but the increase was still a net figure of 24,000 as other operators, primarily Tele2, Phonera (Com Hem) and Telavox, increased significantly.

The number of subscriptions for fixed-line telephony via PSTN12 and ISDN13

continued to decline, while the number of subscriptions for IP telephony continued to rise in 2015.

Subscriptions via PSTN

There were 1.7 million subscriptions for fixed telephony via PSTN on 31 December 2015, which is a decrease of 15 per cent. Of these, 457,000 were via a company other than TeliaSonera via the wholesale product WLR14. The

12 Public Switched Telephone Network (PSTN) is the traditional, circuit-switched public telephone

network.

13 Integrated Services Digital Network (ISDN) is a standard for digital telephony that involves an upgrade

of the traditional copper wire network of at least two channels per subscriber line.

14 WLR is an acronym for wholesale line rental. WLR means that the subscriber can pay both the

subscription and call charges to an operator other than TeliaSonera. Before WLR was introduced in 2005, many subscribers paid a subscription charge to TeliaSonera and a traffic bill to another company (known as 'pre-selection telephony'). 0 500 1 000 1 500 2 000 2 500 3 000 3 500 4 000 4 500 5 000 5 500 2008 2009 2010 2011 2012 2013 2014 2015 Th o u san d s u b scr ip tio n s

number of subscriptions via WLR fell by 15 per cent compared with the previous year.

Subscriptions for ISDN

At the end of December 2015 there were over 22,000 subscriptions for ISDN, which is 38 per cent less than the previous year. TeliaSonera had 51 per cent of these.15

Subscriptions for IP telephony

In addition to traditional fixed telephony (PSTN and ISDN), operators offer IP telephony as a service. This is done through a connection to the IP network over which the operator itself has control, in contrast to what we call internet telephony (services such as Skype).

There were just under 1.9 million subscriptions for IP telephony on the last day of December 2015, which represents an increase of 7 per cent since the corresponding date in 2014. The number of IP-based subscriptions has increased over the last few years and they constituted 52 per cent of all subscriptions for fixed telephony in December 2015. The proportion of subscriptions for IP telephony is thus for the first time more than traditional subscriptions (PSTN and ISDN). An estimated 26 % of IP telephony

subscriptions were inactive according to Swedish Telecom Market in the first half of 2015. Of these, practically all of them were part of combined

subscriptions.

The number of subscriptions for IP telephony via xDSL amounted to 648,000 at the end of December 2015, which represents an increase of 3 per cent since the same date a year previously. At the same time, the number of subscriptions for IP telephony via cable television decreased by 7 per cent and to 327,000. The number of subscriptions for IP telephony via fibre or fibre LAN was 639,000 at the end of December 2015, which represents an increase of 9 per cent compared with the same date one year before. ”Other IP-based access”16

increased 49 per cent and amounted to 238,000 on 31 December 2015.17

15 In this year's report, Tele2 has reported 2,800 subscriptions for 2015 and has corrected their reporting

of ISDN for 2014 from 46,000 to 1,600 subscriptions.

16 This relates to IP telephony subscriptions where the operators have indicated that the access form is

not known.

17 The increase is mainly due to Tele2's increase of 48,000 subscriptions for fixed call subscriptions via

TeliaSonera (41%), Com Hem (22%, including Phonera), Telenor (11%, including Glocalnet and Bredbandsbolaget) and Telavox (7%) are the largest operators in IP telephony and together have 81 per cent of all subscribers.

2.6 Bundling

Bundling in this context refers to offers that contain several services, such as telephony, broadband and television, and are marketed as one offer with a joint price. The most common offers on the market include different combinations of telephony, television and broadband. This does not include bundling with OTT services18 such as Netflix, Skype etc.

bundled subscriptions where fixed telephony is included that a decrease is observed.

TeliaSonera had most subscriptions, followed by Telenor, Com Hem and Hi3G. Together, these four operators had 94 per cent of the bundled subscriptions.

Double play, bundled subscriptions with two services, amounted to 1.1 million subscriptions, which is a decrease of 3 per cent compared with the previous year. The most common form of bundling was fixed telephony and fixed broadband, which is the same as the previous year. There were 702,000 such subscriptions at the end of 2015 and they decreased by 8 per cent compared with the previous year. This represented 40 per cent of all bundled

subscriptions. The third most common form of bundling was television and fixed broadband, which amounted to 232,000 subscriptions on 31 December 2015, and this increased by 35 per cent and accounted for the largest increase. This form of bundling represented 13 per cent of all bundled subscriptions. Triple play, i.e. bundles with three services, fell by 5 per cent between December 2014 and December 2015. The second most common bundled subscription, with just under 580,000 subscriptions, or 33 per cent of all bundled

subscriptions, was for fixed telephony, fixed broadband and television. These subscriptions decreased by 4 per cent compared to the end of December 2014. Bundling with four services, quadruple play, is relatively rare and remained at an unchanged level of 14,000 subscriptions in December 2014. The most

common combination, which remained the same with 8,000 subscriptions, included fixed-line telephony, fixed-line broadband and television and mobile telephony.

Various forms of bundled subscriptions with fixed telephony declined in 2015 by 9 per cent, to 1.3 million subscriptions. This corresponds to 37 per cent of all fixed telephony subscriptions.

Fixed broadband was included in just over 1.5 million of the bundled subscriptions, corresponding to 44 per cent of all subscriptions for fixed broadband. On the other hand, bundles that included mobile broadband corresponded to only around 1 per cent of all subscriptions for mobile broadband.
