C-Band Invasion

C-band frequencies (3.4-4.2 GHz) are vital to operations of satellite services, particularly intropical and subtropical regions, where other frequencies are bedevilled by "rain fade".

Societies in the Asia-Pacific rely on C-band communications to support business communications, telemedicine, distance education, disaster recovery - and of course getting broadcast content to the region's 255 million pay-TV homes.

But other groups have their eye on the C-band frequencies. Several Administrations have already assigned portions of that band for wireless broadband systems - with disastrous results. Now the ITU is being asked to open the C-band for use by future 4-G (IMT) telephone systems.

CASBAA and its members are fighting back against this invasion. Click on the documents below to get educated, and if you are a pay-TV operator, ask your engineering people if you don't rely on the C-band to get the programming you and your customers need. then contact your national telecoms regulator, and let them know that C-band is vital for your business and your links with the rest of the world.

Fight the Invasion! If you're a user of satellite C-band services, contact your regulator. See a template letter here

Faulty Assumptions at the ITU

An Intelsat official wrote an incisive blog post, noting the complications faced by regulators seeking to allocate frequencies, when the available demand models hugely overstate the likely demand for mobile bandwidth. This fits a historical pattern, with mobile interests consistently overestimating spectrum demand, but will have devastating effects in Asia, if governments yank spectrum from their TV consumers to sell it to mobile interests that don't really need it. Read the blog post here.

  

Challenge to Satellite Frequencies Continues

challenge CASBAA Spectrum Consultant Jorn Christensen writes that the challenge to satellite industry use of the C-band radio spectrum will continue, through the next three years of ITU consideration of how to find new frequencies for mobile broadband systems.   The issue will be on center stage at WRC 2015, as it was in the WRC in 2007.    This paper presents an item-by-item survey of the WRC agenda points that will challenge satellite frequencies, and proposes defensive actions by satellite and broadcasting interests, beginning now.

Papers

Mobile Industry's Demand Methodology Challenged

Satellite industry advocates filed with the ITU a detailed objection to plans for assessing likely mobile demand. The proposed methodology produces wildly inaccurate results in many cases, the paper said. "It appears that there are significant inconsistencies in the parameters that have been assumed to build the estimates of the mobile traffic which form a key input of the spectrum requirements calculations. Replacing the traffic assumptions with more realistic values would lead to a significant reduction in the total spectrum requirements," said the paper. Download the paper here.

3.3 – 3.4 GHz band for BWA

"The ITU Radio Regulations make provision for use of the 3.3-3.4 GHz band for broadband wireless and IMT applications. A number of Asian countries have applied this clause and allocated this band for IMT, with considerable success. Some countries, including China, are proposing this band as a suitable frequency range for WRC-15 agenda 1.1. It may be worth considering supporting this allocation."

CASBAA Urges Australia To Avoid C-band for Mobile Broadband; Warns of International Repercussions

In a submission to the Australian Communications and Media Authority (ACMA), CASBAA pointed out that decisions by national regulatory bodies can have serious repercussions for the commercial viability of international services. This is especially true of frequency allocations affecting international satellite services, and CASBAA expressed “deep concern” at ACMA consideration of licensing standard C-band frequencies for mobile broadband services. CASBAA’s bottom line: “We urge ACMA not to further consider using these frequencies for mobile broadband services, as to do so will contribute to jeopardizing essential C-band communication services across a wide swathe of Australia’s neighbouring countries.” Download the document here.

On Guard Against Interference by Wireless Systems

A representative of the Asian satellite industry told a recent ITU preparatory meeting that from the point of view of interference with satellite services, “fixed” wireless services are the same as “mobile” ones. (While the transmitter is fixed, the receivers can be located anywhere within the service area, and potentially cause interference with satellite reception.) To guard against interference, satellite operators should ensure their receiving dishes are registered with government spectrum agencies, and when a wireless operator seeks new licenses in satellite frequency bands, “point out to the administration that a Fixed Wireless Network is not a fixed service as defined in the ITU Radio Regulations, but that the interference potential of a FWA transmit/receive network is the same as for a mobile network.” And the satellite industry should support proposals to WRC-12 under Agenda item 1.2 to require land point-to-area transmit/receive applications to be notified as mobile services. See the ITU document here.

the Other Side of the WiMax Wars: LTE versus WiMAX
In comparing LTE (Long Term Evolution) versus WiMAX it is necessary to be more specific. LTE is a mobile technology and WiMAX has standards for both mobile and fixed networks. Therefore, a meaningful comparison should be between LTE and mobile WiMAX. To read the full document click here.

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

Real-life field study of the effect of a WiMAX system in an urban area

Amsterdam_sClick to enlarge

A field study in Amsterdam demonstrated the effect on satellite services of an operational urban WiMAX system. The conclusions are that "An operational WiMAX system in an urban environment will not allow for any acceptable satellite reception at an observed distance of 34 km," and "(the system) caused a raised noise floor at a distance of 44 km which would be in excess of the long-term protection criterion."
