CTIA 2012: 7 Wireless Terms for Videographers to Know

by Jackson Wong | May 8th, 2012

In honor of CTIA 2012, we want videographers to be more aware of wireless terms, some you may know, but the less you need to glance at glossaries, the better. These come from a few CTIA pages on consumer information,

1. Federal Communications Commission (FCC): An independent U.S. government agency responsible with regulating interstate and international communications by radio, television, wire, satellite and cable. This includes all aspects of the wireless industry such as devices, policies, programs and outreach initiatives.

This is a big one, this national agency regulates pretty much anything that TV and radio stations play. The inclusion of the wireless industry means, that the Wi-Fi camera you just got, must follow the agency’s guidelines. The FCC is also the agency responsible for setting the standards for many aspects of video, particularly, which frequencies your devices are able to use.

2. Filters: Most wireless carriers provide parents with the ability to filter Internet content accessed on a wireless phone on their network.

Not to be confused with many other definitions of filters, the International CTIA WIRELESS filter is generally one that provides you squeaky-clean Internet videos, text, and photos that are mainly concerned with the well-being of your device. These filters will often appear in the form of software, and while there is software with filters for video, our favorite filters are the physical ones that will modify the images you’re capturing with your little devices.

3. Interoperability: The ability of a network to coordinate and communicate with other networks, such as two systems based on different protocols or technologies.

Interoperability is really a measure of how well systems can communicate or share. This should be familiar territory for any videographer that’s had to work with containers or codecs extensively. What we’re looking for is simply being able send video from one device to another, in different areas – the smoother, the better in this case.

4. LTE (Long Term Evolution): The next-generation network beyond 3G. In addition to enabling fixed to mobile migrations of Internet applications such as Voice over IP (VoIP), video streaming, music downloading, mobile TV and many others, LTE networks will also provide the capacity to support an explosion in demand for connectivity from a new generation of consumer devices tailored to those new mobile applications.

Largely dependent on which is available to you, 3G or 4G, LTE is tagged onto 4G since it is the most current network and is committed to supporting expansions in the realm of video delivery. Video will get further versatility as long as LTE can keep up.

5. Packet Data: Information that is reduced into digital pieces or ‘packets’, so it can travel more efficiently across networks, including radio airwaves and wireless networks.

Packets and Packet Data are like the media cards you may use with your camera, but on a minuscule scale. Rather than uploading a 2GB video all at once, parts of it are sent over time, thus, you get buffering. This can really help make video smooth, just give the packets time to move.

6. Smart Phone: Wireless phones with advanced data features and often keyboards. What makes the phone “smart” is its ability to better manage data and Internet access.

Indeed, we have now learned what makes you smart, being able to manage data and access the Internet, no wonder those fifth graders do so well! In all seriousness, being able to access the Internet opens a host of video applications since so much video gets downloaded and uploaded every minute – 60 hours and that’s just on YouTube. Now you may consider an app that lets you edit video or provide a viewfinder for your sportcam. When it comes to data management, there’s likely a very high percentage of videos and films that would fail as early as pre-production if not for such smart phones.

7. VoIP (Voice over Internet Protocol): VoIP is a two-way communication service that can allow users to communicate via voice or video. Based on IP technology, VoIP is used to transfer a wide range of different type traffic.

Webcam-ing may be forever tied to VoIP so just know, if you use FaceTime or Skype, you are using VoIP, and clearly it has already made great improvements from its early days in the mid 90s.

Keep checking our video news blog for the latest from CTIA 2012, and we’ll keep searching for the most notable video developments the event has to offer.

White House Swallows Up 500 MHz of Wireless Spectrum

by Daniel Bruns | June 30th, 2010

In a bid to take up even more of the wireless radio spectrum, President Barack Obama has signed a presid

ential memorandum supporting the FCC’s release of  500 MHz of wireless spectrum for broadband services. It’s been no secret that the FCC has been trying to play catch up with Europe on broadband speed and technology. This new initiative paves the way for the FCC to sell spectrum that can potentially deliver wireless broadband speeds of up to 100 megabits a second to 100 million homes in the United States. It also makes it possible for the FCC to create a nationwide safety communication network, something they’ve been trying to accomplish ever since emergency workers across the country had trouble talking to one another during the September 11th attack.

The FCC is currently fast-tracking an exploration of the broadband spectrum that is still available and how quickly other parts of the spectrum will open up. As the wireless spectrum is limited and is in high demand, this freed up spectrum is expected to go for more than 10 billion dollars when the FCC sells it in the next 5 years. This is money that will go towards both the safety communication network infrastructure and to actually pay off the national debt.

Of course on the video side, the only real question is does this mean that we’ll have to buy new wireless microphones again? The 700 MHz frequency range has already been sold off so who’s to say that wireless microphone frequency holders might not want to sell off more? Plus with all of the other important uses for the other parts of the spectrum, there can be no doubt that the pressure will be high for wireless microphone frequency holders to sell out. On the plus side however, if that event does occur,  you should have no problem getting updated quickly on your new 100 megabit per second wireless connection.

Sennheiser’s Open Frequency Finder

by Derek Sine | April 30th, 2010

With more and more devices crowding the airwaves it can be hard to find an available frequency without interference while setting up your wireless mics. Sennhesier has a solution, an audio tool for finding open frequencies that incorporates the FCC TV broadcast database.  Simply enter either a City or Zip Code and the application provides you with a list of available and used frequencies. This is another one of those must have tools for any filmmaker serious about getting great audio without spending time looking for an open frequency which we all know can be very time consuming.

FCC Proposes Ban on Wireless Microphones in the 700MHz Spectrum

by jburkhart | August 22nd, 2008

Radio WavesOver at ArsTechnica, there’s a great writeup on the FCC’s proposed ban on wireless microphones that operate between the 698-806MHz frequencies.

The FCC recently auctioned this space off due to the end of terrestrial analog broadcast in February of 2009, and the telecom companies that bought this spectrum, don’t want wireless mics interfering with their new frequencies.

“In July, a consortium of public interest groups warned the FCC that unlicensed wireless mic use in the area poses a threat that will become more pronounced after the DTV deadline. The Public Interest Spectrum Coalition’s (PISC) petition estimates that between 500,000 to 1 million unauthorized wireless mic systems operate in the 700MHz channels, “creating pools of potential interference that could undermine the reliability of these new public safety and commercial wireless systems.”

Most manufacturers stopped selling mics in this range last year, but if you have an older wireless system it’s possible that your wireless mic could soon be illegal to use in the United States, if it falls within those frequency ranges.

The complaint specifically targets these manufacturers:

Complaint of Public Interest Spectrum Coalition (PISC) Against Shure, Inc., Nady Systems, Inc., VocoPro, Audio2000, Sennheiser Electronic Corporation, Audix Microphones, Electro Voice, Hisonic International, Inc., Pyle Audio, et al.
