Cable-Tec Expo 2009: Aurora Cranks QAM Transmitter To 80-Plus Channels Oct 29, 2009
Aurora Networks is taking the wraps off a QAM transmitter designed to support more than 80 quadrature amplitude modulation channels, with an eye toward delivering more broadband, VOD and other narrowcast services. The AT3535G, which the company is introducing at this week's SCTE Cable-Tec Expo, is a sizeable step up from the 48 QAM channels supported by Aurora's previous AT3520G model. (Multichannel News)

A QAM (quadrature amplitude modulation) device. In the past year or so, according to Manchester, the cost of edge QAMs has dropped in half ; from $300 per channel to about $150. (Multichannel News)
Assessing Cable's IPTV Future Sep 26, 2009
"We see a lot of variability out there."Before they go to a full IPTV architecture, cable operators are looking to mix and match, delivering supplemental IP video to the TV while the bulk of the linear lineup continues to be MPEG-2 video over quadrature amplitude modulation (QAM) channels. Set-top box makers including Cisco Systems and Motorola have introduced hybrid QAM-IP devices that allow the blending IP video using embedded DOCSIS cable modems. (Multichannel News)
NEC Exhibits PASOLINK NEO High Performance (HP) at Broadband World Forum Europe 2009 Sep 8, 2009
PASOLINK NEO HP is the top end of NEC's PASOLINK NEO product line and boasts Multilevel Quadrature Amplitude Modulation (256QAM), which more than doubles the machine's transmission capacity when compared to current PASOLINK models (more than 1Gbps capability). Moreover, the system boasts VLAN/Qos/AMR functionality, and high capacity IP data transmission, which is required for mobile backhaul as well as for networks supporting WiMAX and communications between mobile phone base stations and base...

Cloud ships 'to deflect sun's rays and stop global warming'... Aug 8, 2009
" Facts, who needs them. Who the hell qualifies as a "scientist" these days. Remember, only you can prevent global warming - by spending more tax dollars. Mmm, nutty goodness on August 08, 2009 at 06:36 AM I have a better idea. We can breed giant emus that have been genetically modified to fart water vapor and introduce them to every continent. Emu farts are the only way we can save our planet! Monkey Johnson on August 08, 2009 at 06:36 AM Yes the planet is warming, then it will cool, then warm.... (The Drudge Report)
BigBand's 'Supergroup' Jul 27, 2009
The vendor's new Converged Video Exchange (CVEx for short) is designed to let operators create a single pool of quadrature amplitude modulation channels. The system then manages subscriber requests for services and allocates bandwidth on the fly, working with other resource managers. (Multichannel News)
NPL helps develop unique new calibration tool for radio frequencies Jun 23, 2009
However, in the case of amplitude modulation (AM), Fluke had a measurement problem. The usual methods of measuring AM have too high an uncertainty to be able to verify that the instrument is as good as Fluke believe it to be. (EurekAlert! -- Business News)
Chips Down on Personal TV Jun 16, 2009
If every single household in a neighborhood were to receive its own, personalized video stream, cable networks would not only need more spectrum reallocated for those services they'd also need a bunch of new quadrature amplitude modulation devices. BroadLogic Network Technologies this week is expected to introduce the TeraQAM BL85000, a chip designed to quadruple the density over existing QAM solutions for less than 50% of the cost.

Elder was directly involved in Comcasts switched digital video edge quadrature- amplitude modulation unit purchase from Arris, the initial Time Warner Cable cable-modem termination system business and Comcasts many long-term media terminal adapter and CMTS purchase agreements that have resulted in 300% growth in that MSOs business with Arris within a three-year period. The Internet has changed everyones perspective on how they receive content and information, he said. (Multichannel News)
Sticking up for Cox as it makes a change Apr 2, 2009
If you have a newer TV with a built in digital Quadrature Amplitude Modulation (QAM) tuner, and will only be subscribing to basic/expanded services, you do not need to put a box on that TV. It will still pick up channels 2 to 99. Any TV with an analog tuner, or a non-QAM digital tuner, will need a box. (Sierra Vista Herald, AZ)
Motorola Ships 1,000 'Wideband' CMTS Modules Feb 12, 2009
The vendor's TX32 Decoupled Downstream Module supports 32 quadrature amplitude modulation (QAM) channels in a single slot in the Motorola BSR 64000, to deliver DOCSIS 3. 0 channel-bonded services of up to 200 Mbps downstream. (Multichannel News)
Better reception is on the way, say representatives of cable company Feb 11, 2009
The only exceptions are customers whose TVs have a Quadrature amplitude modulation or QAM tuner. It is a device present in some digital televisions that enables direct reception without the use of a converter box. (Nogales International, AZ)
