Are You Ready for Carrier ID?
Steven Soenens, Vice President, Product Management, Newtec
With a growing number of satellites, satellite service providers and broadcasters taking up precious
space segments, satellite Radio Frequency Interferences (RFI) is an ever-growing threat to our satel-
lite industry. Carrier Identification (CID) has been proposed as the solution to reduce Mean Time To
Repair (MTTR) of service outages due to interferences – but how exactly does it work and how do
operators go about getting it? This article explores the set up of the unique ‘fingerprint’ and how it
can improve services and cut costs.
The unique carrier identifier ‘fingerprint’ is an essential tool for reducing the impact of satellite
interferences, as it helps to pinpoint the source of interference quickly, enabling faster resolution as a
result. The big question for operators used to be ‘should we implement CID technology as well?’. This
question became irrelevant this July, though, when the WBU-ISOG resolution set the requirement to
have CID implemented into all SCPC/MCPC satellite infrastructures.
Although the WBU-ISOG resolution was passed in July, the transition to mandatory CID is set to really
start from January 1, 2015 (see Figure 1). New satellite ground segment equipment, should be ready for
CID right now. By January 2018 all uplinkers will ensure CID is included for all their respective SCPC
and MCPC video and data transmissions and CID NIT, the previous and less robust version of carrier ID,
shall be phased-out in favour of the more robust ETSI TS 103 129 standard, often referred to as DVB-
CID. Most operators are likely to welcome the WBU-ISOG resolution and consequent transition.

An industry-wide survey carried out by the Satellite Interference Reduction Group (IRG) and satcom
specialist Newtec this August asked nearly 500 respondents to share their opinion on CID. A huge
93% of respondents suffer from satellite interferences, with nearly a fifth of participants (17%)
suffering continuously and another 27% claiming to experience interference as much as once a week
(see Figure 2). Furthermore, 86% of respondents stated standards such as DVB Carrier ID were
‘important’ in overcoming satellite interferences (see Figure 3) and 33% said the most compelling
reason to implement CID was to ‘Improve my quality of service and user experience (and as such my
business)’ (see Figure 4)

a quick yet cost-effective transition for the industry.
The third and final key date for operators’ diaries is January 1, 2018. This is when it all becomes very
clear – all uplinkers must ensure that Carrier ID is included in all their respective SCPC and MCPC
video and data transmissions. By this time operators need to have put together a plan to complete
their transition to full ETSI TS 103 129 CID on all equipment.

Newtec was pleased with the response they had to the survey because it showed our industry is
engaged with the CID subject. The topic has clearly moved from talking about satellite interference to
what action should be taken to prevent satellite interferences. There are clear signs that operators,
services providers and broadcasters will be taking the necessary steps soon.
As to why the respondents to the Newtec and IRG survey are so keen on CID, operators need only
look as far as sports tournaments and the increasing demand for high quality broadcast to find the
answer. During the 2012 Olympics, 50% of satellite operators’ transmissions were implemented with
Carrier ID. The result was an improved transmission Quality of Service experience and reduced oper-
ating expenses with a noticeable reduction in interference, especially when compared with previous
tournaments. With other sporting events, such as the Winter Olympics, the FIFA World Cup and the
Commonwealth Games coming up, CID will be even more desirable to ensure the viewing experience
is as high a quality consumers expect it to be!
