Category Archives: 60GHz Unlicensed Wireless
Essentially all of the wireless radio frequencies (literally DC to light) have been allocated to specific uses by the FCC or similar regulators in other countries. Most of the available frequencies require users to get licenses that specify exactly which RF channels can be used in which locations at specified power levels for defined applications. A few frequency bands are unlicensed, such as the 2.4 GHz Wi-Fi and the 60GHz bands, and are therefore available for anyone to use in any location provided certain limits on effective radiated power are observed.
Licenses to use specific radio frequencies are a good news/bad news proposition. The good news is that a license gives a broadcaster an exclusive right to use a particular frequency in a defined location for a specific period of time. This helps ensure that other users will not create destructive interference with the signal. The bad news is the cost and the paperwork that are necessary to obtain the license, not to mention the time for the application to be processed. In addition, licensed frequencies may only be available in specific, pre-defined locations, making “grab and go” shooting more difficult.
Initial & Recurring Costs
Any wireless video solution will have some sort of an up-front expenditure, related to the costs of purchasing, installing and configuring the necessary equipment. Some solutions will also have a cost associated with each use. For example, a system that uses a cell-phone network for backhaul will need to pay for the data consumed by each transmission, either directly (as a bill for gigabytes) or indirectly (built into the cost of the service/device).
The unlicensed spectrum has no associated licensing and bandwidth fees. Since there are no licensing fees and less usage regulations, unlicensed spectrum has a much higher chance of interference by other users. Typically unlicensed frequency bands have a narrow, more controlled bandwidth usage. The 60 GHz, 70/80 GHz and 90 GHz frequency band are the exception having wide channel bandwidths.
The licensed spectrum typically has associated fees for spectral and bandwidth usage. There is typically less chance of interference and congestion with less users operating in the same spectral band. Typically a licensed band offers more available bandwidth than a comparable unlicensed band. Licensed spectrum typically offers higher reliability and greater transmission distances.
VidOvation is a Video Communications Company
Larry Jordan: Jim Jachetta is the Founder and President of VidOvation. For over 20 years, Jim’s been designing, integrating and delivering video, fiber optic and data communications systems and recently they’ve expanded into wireless video with some new technology being used by the NHL. Hello, Jim, welcome.
Jim Jachetta: Hi, thanks for having me. Pleasure to be here.
Larry Jordan: We are delighted to have you with us and let’s start with a really easy question. First, tell us about what VidOvation is.
Jim Jachetta: VidOvation is a video communications company. We manufacture solutions for wireless, solutions for fiber optic transmission, for webcasting, we make encoders to stream video over your corporate network or through the internet, but in a nutshell we help our clients move video from Point A to Point B and our tagline is ‘Moving video forward’, so we’re staying up to date with the latest technologies such as what we did for the National Hockey League, using 60 gigahertz transmission for uncompressed wireless video.
Larry Jordan: Let’s just take a second. We understand that you guys are in the business of moving video, but you’re one of the founders of the company. Why did you decide to start the company? What made that so intriguing to you?
Jim Jachetta: Well, I guess I have my dad to blame for that. My dad had an entrepreneurial spirit. My dad was an engineer at ABC, CBS and his longest and final stint was at NBC, so he worked at 30 Rock for about 12 years before starting a company called MultiDyne and, as kids, my brother and I, we always worked for our dad so junior high we helped stuff circuit boards and build a lot of his audio visual equipment, so it’s in our DNA and my dad was a great problem solver and my brother and I have inherited that work ethic of doing the never been done before and solving our clients’ problems or helping with their business workflow.
VidOvation on sports officiating with 60 GHz Wireless
The NHL had an issue and realized that traditional wireless & cables just wouldn’t cut it. The variables they were dealing with put a strain on them to seek out alternatives. They found the 60 GHz wireless technology of VidOvation and asked for a custom built camera system based on that technology. The technology transmits uncompressed video using 1.5 of the 7 GHz available in the 60 GHz band. Jim Jachetta speaks about this specialized 60 GHz Wireless project in this interview Ken Pyle of The Viodi View.
How can 60 GHz Wireless help you?
You wouldn’t have any trouble if variables X,Y,and Z didn’t exist, but they do exist, and they’re undoubtedly causing problems. So you’re troubleshooting this obscure issue, but all of the tricks in the book are falling short of resolving the situation. What can you do? What are the options for your project? It is important to understand all of the options available to you regarding technology and spectrum. One of the newer available options to you is 60 GHz Wireless. The interview above is testimony to its reliability and multitude of applications.
Save Money with 60GHz Wireless
We understand the pain of projects hindered by the limitations of traditional cable & wireless. That’s why on Thursday, the 26th of June, we will be hosting a webinar on the 60GHz Wireless broadcasting solutions for remote & hostile locations. We will introduce ways in which you can keep under budget, whilst choosing the ideal technology & spectrum for your projects. By the end of the session, you will be an expert on the array of wireless alternatives and understand how to create a reliable wireless system for your own unique project.
60GHz for YOUR project
Your own project is no doubt different in some way from every other. It’s full of its own set of anomalies & issues. The best way to learn how to deal with these struggles is by using a strong example. In our webinar, we will use the NHL GoalCam project as an example as we walk through the underlying restraints of the project, the budget decisions, RF bands alternatives, licensed vs. unlicensed spectrums, polarization, and ultimately what made 60 GHz Wireless their best option.
The availability of 60 GHz Wireless opens up a whole new set of operational improvements for broadcasters. If you want to learn more about it, you know where to go!
