Join Our Efforts to Safeguard C-band Spectrum!

Monday, 04 February 2013

Asian broadcasting and satellite organizations have united to appeal for attention and support by companies in Asia’s many countries and regions for efforts to safeguard the satellite C-band frequencies which are the lifeblood of broadcast distribution in our region.  These Associations have issued a joint appeal, which we attach, and urge all CASBAA members to consider and implement.

C-band frequencies are under threat as the ITU seeks additional frequency spectrum to assign for broadband wireless systems.   Some mobile equipment manufacturers and mobile operating interests are mounting a concerted campaign to have the ITU declare part or all of the C-band as open for mobile use.  This would be disastrous for the broadcasting industry.

The Associations – which represent the entire breadth of the broadcasting industry in Asia -- believe it is important that broadcasters act NOW; we ask the broadcast community to join efforts with the satellite industry to safeguard C-band spectrum for satellite services.  The joint statement attached describes what needs to be done.

This statement has been endorsed by the Asia-Pacific Broadcasting Union, the Asia-Pacific Satellite Communications Council, and CASBAA, as well as the World Broadcasting Union (International Satellite Operations Group and the Global VSAT Forum.

Asian Satellite Reps Describe C-band Interference Challenge

Thursday, 06 December 2012

CASBAA’s consultant Jorn Christensen and experts from member company Asiasat united to deliver a scientific paper and presentation to the prestigious IEEE Globecom 2012 conference in Anaheim, CA, USA on December 6, 2012.   Christensen told the 2,000 assembled delegates from the global electronics and communications industries that interference into satellite reception from terrestrial broadband wireless systems is a real and growing problem in many countries.   The likelihood is for the situation to get worse, he said, and the ITU is debating opening up the C-band for broader use, with potentially disastrous consequences.    Download the presentation above, and the scientific paper here.


Concerns over Space Assets Protocol

Tuesday, 13 December 2011

CASBAA has joined the European Satellite Operators Association (ESOA), the Satellite Industry Association of (SIA) of the United States and the Space Industry Association of Australia (SIAA) to express urgent global concern over proposed new international legislation, the Space Assets Protocol, sponsored by the International Institute for the Unification of Private Law (UNIDROIT) based in Italy.

Meanwhile, some 90 satellite operators, manufacturers and financiers drawn from around the world have also written to UNIDROIT and its member governments to register their own deep-seated reservations.

CASBAA Joins WRC Prep Meeting

Wednesday, 06 July 2011

CASBAA’s WAG Consultant, Jorn Christensen, represented the Association at a July 4-6 Asia-Pacific Broadcasting Union (ABU) preparatory meeting for WRC 2012.   Christensen spoke on the importance of obtaining ITU recognition that a “fixed”  wireless broadband service is often equivalent to a “mobile” one, from a satellite interference perspective, as the receiving terminals (computers) can be effectively located anywhere in the service area, even if they don’t “walk around.”   He used a recent Satellite Industry Committee Presentation to brief the ABU’s free-to-air broadcasters on C-band interference challenges.

What's Up with WiMax?

Monday, 16 August 2010

CASBAA published an update report entitled "What's Up with WiMax?" for member companies on the prospects for actual and potential interference between broadband wireless systems and Asian satellite transmission systems in the C-band. The report notes that spectrum pressures for broadband will be highest in large countries with underserved rural areas, including Australia, China and India. Download the update paper here.


ITU Reports Underline incompatibility of wireless and satellite services in the C-band

Monday, 08 February 2010

The C-band invasion by wireless services is not going away, and CASBAA broadcaster and satellite operator members will need to keep in touch with their regulatory authorities to urge continued protection for the C-band. Recent documents published by the International Telecommunications Union's Study Group 4 (SG4) underline the practical impossibility of coexistence in the C-band for broadband wireless services (such as WiMAX) and satellite telecommunications. This ITU group has a Working Party whose preliminary draft new report entitled "Studies on compatibility of broadband wireless access (BWA) networks and fixed-satellite service (FSS) networks in the 3 400-4 200 MHz band" has been summarized for CASBAA members here.

CASBAA notes ‘Transmission Troubles’ from WiMax deployments

Wednesday, 29 October 2008

CASBAA today released a new report highlighting the threat to television services posed by the deployment of Broadband Wireless Access services (such as WiMax) in the radio frequency band used for the wholesale distribution of satellite television signals in Asia.

New study finds terrestrial wireless deployments fall far short of projections

Wednesday, 24 October 2007

A Futron study shows that underperformance of wireless adoption, combined with severe Wi-MAX interference, argues strongly against proposed reallocation of C-band spectrum.

Position paper on recent developments of C Band

Friday, 19 October 2007

Various regional and sub-regional groups have reached conclusions on whether some or all of the 3400-4200 MHz band ("C band") should be identified for IMT and there is a clear trend towards 'no change' to the current uses of the band.
