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

Click 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."
