DECT Wireless Technology…Where does it fit?

Wireless Frequencies

With the ever-decreasing bandwidth associated with wireless microphone technology in the UHF band, other wireless bands had to be explored. There is the VHF (Very High Frequency) band with a range of between 25 and 300 MHz, with most of this now unlicensed for wireless microphone operation. Then there is the 900 Mhz band. This falls into the 900-928Mhz range and is used frequently, although restricted by internet service providers who have established networks in this range. The UHF band, which operates in the 400 Mhz to 900 Mhz range. UHF has been widely used for various types of wireless microphones as well as other commercial communications. UHF was severely impacted by a FCC ruling that effectively banned any wireless microphones in 698 to 806 MHz portion of the UHF spectrum in 2010. Then in 2020, largely restricted this further to 600 MHz or above.

This portion of the wireless spectrum is now controlled for UHF TV broadcast and commercial use only. Then there is 2.4Ghz, which is allowed to operate within the 2.400 Ghz and 2.483 Ghz only. As you might imagine, this portion is also heavily used by Wi-Fi devices, which can cause unwanted dropouts as well as low component use, typically 4 units or less.

Finally, we come to DECT, which stands for “Digital Enhanced Cordless Telecommunications” and was originally launched in 1993. This operates in the 1880-1900 MHz band with channels available from 1881.792 to 1897.344 MHz with a gap at 1728 MHz. In the United States, the DECT frequency allocation is 1920 to 1930 MHz. This is now commonly referred to as DECT 6.0. This band will not interfere with Bluetooth or Wi-Fi technologies and allows for significant channel counts to be used.

Why DECT?

This technology virtually eliminates interference from other wireless devices and connectivity up to 350 feet. In some cases, this system can also use high channel density with up to 96 microphones capacity. The downside is that the system requires it’s own wireless network with access point and repeaters in some cases. There is additional cost for this equipment, but for larger systems, it is offset by the functionality of the system. Also, no other devices use this portion of the wireless spectrum.

The only other disadvantage that must be understood with DECT is the TDMA (Time-Division Multiple Access) technology it uses. There is an inherent delay or latency with the system, as each device must connect to a predefined time slot. This delay or latency is typically 18-20ms between the input of a microphone to the output of the access point. This can impact live applications and must be understood as part of any DECT system. For UC usage, it is unlikely that is would ever be noticed as there is already inherent delay for any UC communication.

According to Holger Stolze of Yamaha UC, “The problem of latency can be controlled by where the loudspeakers are placed with respect to the microphones in a voice lift scenario, and therefore DECT devices are not typically recommended for performance use such as singing or other live performance applications.”

So, with this understanding, DECT has quickly become the most widely used wireless technology for conference applications. Also, in many instances, the manufacturer will assist with applications, access point, and/or repeater location and how the system should be set up for the intended use. Panasonic Professional has a team of engineers who will provide a complete set of instructions, programming notes, and even room diagrams to assure the system functions properly. Petro Shimonishi of Panasonic US tells it this way:

church audio solutions

“Panasonic leverages our 30+ year history of innovation and leadership in DECT wireless technology. These products have been designed with the end-user in mind. The system can even be integrated with our PTZ cameras to allow for voice triggered camera presets for a more seamless conference experience.”

Finally, the other real advantage of DECT over other more prominent wireless microphones like UHF is that it does not require frequency coordination, as it is automatically managed by the number of microphones in a given system. This is unlike UHF, which requires careful and sometimes difficult frequency coordination where multiple channels are used or where adjacent units can bleed into the spectrum, causing unwanted dropouts or interference.

The bottom line here is the DECT wireless has quickly become the gold standard for teleconference and videoconference applications. Excellent sound quality and ease of use keep these products in high demand. When you think of conference applications and need a wireless solution, contact your Exertis Almo representative or visit ExertisAlmo.com.

Behind the Panel: Cameras for the House of Worship Market

Welcome to this installment of “Behind the Panel,” detailing everything you need to know about cameras for the House of Worship (HOW) market. I realize that this doesn’t technically fall “behind,” so, for this edition, open your minds and we will go “beyond” the panel. By now, I am hoping you had a chance to read my colleague, Rob Voorhees’, blog post, titled “Streaming into the Future; How Bandwidth Needs Have Expanded for Houses of Worship,” which focuses on dedicated bandwidth for the HOW market. If you haven’t, go now and I will wait here for you…

All caught up?? Fantastic, we are moving on! As Rob mentions in his post, streaming services online has been done for quite some time, but the COVID-19 pandemic really forced houses of worship to change the way they reached their congregation. Reading some statistics online, prior to the pandemic, about 40% of churches said they neither livestreamed their service nor posted online later. As we moved throughout 2020, more and more churches, about 65%, said they were streaming services, with 27% saying they posted a sermon online later. What does all this mean? To me, it means if your HOW is not streaming today, they should be ready to make that jump, because even though people have been making the transition back to in-person worship, the pandemic has shown value in making these services available online, whether to sick congregation members, or churchgoers all over the world, wherever they may be. Statistics from Lifeway research included here.

How do you get your local house of worship up and streaming? Well, you have a great start with all that extra bandwidth they have now, so let’s look at how to choose the right camera. We will be looking at PTZ (Pan, Tilt, Zoom) Cameras. Pan is the ability of the camera to move left/right of center. Tilt is the camera’s ability to move up and down. Zoom is the camera’s ability to move in and out, whether done digitally or optically with the lens. Keep in mind with digital zoom, you lose quality as you zoom in on the image. There are cameras that can provide 12X, 20X, 30X, or even greater optical zoom.

Here are some questions that need to be answered when specifying a camera.

What type of connection will be used?

There are many different ways, including HDMI, SDI, and USB. There are benefits to each, but one of the biggest differences is how far the signal can travel on each. SDI can send signals up to 1000 ft. without loss. HDMI can travel up to 50 ft. without the use of extenders. USB is limited to just a few feet. So, paying attention to infrastructure and the budget is very important in making these decisions. It is significantly less expensive to run a few hundred feet of coax cable for an SDI solution than adding extenders to an HDMI solution.

Now, these are great for places with a healthy budget, but what happens if you have a church that is still running on an older technology, like S-Video? Check out what our friends at Vaddio have done. The PrimeSHOT 20 was designed with the HOW market in mind. It comes with 20X optical zoom, 1080p @ 60 fps Resolution and an S-Video output. The camera can detect and downscale the image to S-Video, so you can upgrade the camera in a legacy system, and come back and upgrade the cabling at a later point! Check it out here: PrimeSHOT

Where / how far are you placing the camera?

Important to keep this in mind, because the last thing you want to do is choose a zoom level not high enough for the church’s needs. They may want a wide shot to get the whole stage, or focus on the speaker by getting in tight. Check out this Camera Selection Guide from Vaddio to decide what is best for your local HOW. Don’t forget, these cameras all come with compatible wall mounts, so you have that option right out of the box.

How are you controlling the camera?

Although they come with standard with an IR remote, most HOW will want to have a little finer control over their system. All Vaddio cameras can be controlled via a web browser interface, pictured here >

This gives them great results for a lot of basic streaming. If they are looking for a higher “production value” look no further than the Vaddio ProductionVIEW Precision Camera Controller. This gives the user a broadcast-quality joystick to control the PTZ aspects of the camera, as well as the ability to control up to seven PTZ cameras. It’s not for every church, but for those that are serious about streaming their services, it is definitely worth a look.

I think the important thing to keep in mind, like anything else, is listening to what the customer needs. It seems so simple, but digging in to really find those needs out, as well as identifying future what growth they may see in the future, will allow you to craft a solution that can be friendly to the budget, while, at the same time, giving opportunity for repeat business as they look to expand on the initial solution.

I will leave you with this case study from Heritage Lutheran Church just to show the vast potential for streaming in the HOW market.

Thanks for reading.

l look forward to any feedback you might have. Otherwise, see you next time, when I will venture back “Behind the Panel!”

Streaming into the Future: How bandwidth needs have expanded for Houses of Worship

Let us rewind the clock to early 2019. I was in a discussion with a customer who asked me what the top verticals were in regards to bandwidth needs. I had received this very common question countless times, so I answered in the same manner: hospitality, bar & restaurant, education, etc. As we happily fast-forward through 2020 and 2021, I would now place House of Worship amongst the top 3. The reason is quite simple — as the Hospitality and Bar/Restaurant markets clearly battled the ripple effects from the pandemic, it was Houses of Worship who I believe felt a similar impact that few were prepared for. Houses of Worship rely on the some of the same factors as those other verticals do, but the impact can be overlooked if you are not able to predict the future. To survive, these places of worship must keep their doors open for the community and be able to spread their message to the congregation. Shutter those doors due to a global pandemic, and the message risks getting lost.

It was quite fitting that in February 2020, less than 30 days from the time that the state of NJ shut down, I found myself attending a project walk-through at Groveville United Methodist Church in Groveville, NJ. The purpose of this visit was to update the audio/visual and to use this new technology to attract new members in the future. One by one, the integrator and I ran through qualifying questions to better identify the needs they had as we assembled the perfect bill of materials. I asked the church’s technical director if he planned on streaming services or events, to which he immediately said, “We prefer to have folks here in person.” Having understandably not been able to predict what the future held, I certainly do not blame him or others for replying in that manner. As we fast-forwarded to April 2020, I remember a phone call with another integrator who seemed exasperated on the call as he explained, “I have this very small, rural church in Illinois, and they desperately need to be able to stream their services to reach their members at home.” This was the moment it became the clearest – Houses of Worship had a dire need to reach members near and far and to achieve that, Bandwidth was the top requirement.

Streaming used to be a “cool to have” rather than a “have to have” need in this space. Most would probably associate streaming to the Mega Churches that we see on TV or in major cities. However, much like how the Pro AV industry and the push to use AVoIP, HoW have grown to accept that streaming simply cannot be overlooked. The question becomes, “Where do we even begin?” I say, start at bandwidth! There are two types of bandwidth in play here: the bandwidth that you are streaming at and the bandwidth that the stream is being watched at. Let us address these in two separate ways. Bandwidth is provided with two numbers – a download speed and an upload speed. When I refer to something as a 100×10 that means 100mb download and 10mb upload. When we are discussing streaming needs, we pay closer attention to the “UP” number specifically, because you are uploading the stream of the video and sharing this content to a larger audience. A general rule of thumb is that you have no less than a stable 5mb (megabits) upload speed to successfully stream. Given how most high speed cable internet providers start at 10mb upload speeds nowadays, this should not be too difficult to achieve. With that being said, any internet customer needs to understand that just because you are paying for a 100×10 cable package, does not mean you are receiving consistent 100×10 speeds. Those numbers are simply the “maximum advertised speeds” that the provider promotes, but when you factor in things like network traffic, time of day, and other extenuating circumstances (think about the number of people working from home and homeschooling in 2020 as an example), the speeds you receive in real time will almost normally be less. It is because of this that I never would recommend the bare minimum. For typical streaming needs, I would be comfortable recommending a 300×20 package or higher. This should ensure that you never run into issues when you can least afford to! Thinking back to the small, rural church I mentioned earlier, they were relying on a local DSL connection, which only had upload speeds of 1.5mb, hence their dire need to improve.

The second type of bandwidth we need to be cognizant of is the bandwidth at which the video is being watched. Obviously, it is an impossible task to attempt to determine the bandwidths of everyone who is watching, so you might want to offer the stream in different forms: HD, 4K, etc. A good HD stream would fall under the 5mb recommendation I just made, whereas 4k would cause that to rise, but again, say 10-15mb most high speed cable options will suffice nowadays in regard to the content streaming. While talking about the content streaming, we cannot overlook other factors such as the overall number of devices on the customer’s network. Thinking about your own home as an easy example. You probably have cell phones, smart TVs, thermostats, alarm systems, tablets, PC’s and more all tied to your home network. If you now apply that same thought to HOW you may have some similarities such as cell phones, PC’s etc. but now you might also have streaming cameras, audio components, assistive listening devices and more to consider. It is because of this that many HOW will look to a Dedicated Internet Access (aka Fiber) because it is as the name implies. You are receiving a dedicated service for your building that is backed by an SLA (service level agreement) therefore; you are receiving the speeds you are paying for. It might be wiser to look at a 50×50 DIA service instead of that 300×20-cable service, based on what your needs are and what your network looks like. Sure there is an increase in cost with DIA, but the peace of mind you will receive each time you attempt to stream a service is worth it in most cases. Wouldn’t you agree?

Bandwidth within HOW is not a “one size fits all” model. I have already mentioned high-speed cable, DIA, and DSL as examples of what is out there. You also have wireless and satellite services, which in the right situation, could still be viable sources. What do you do when you are a small/rural church with no cable or fiber internet available within 100 miles? You possibly turn to a satellite internet service, which is available, nationwide and while not as adequate as a 10mb upload speed, can still offer 4mb, which for a small church should do the trick. The key is- options are available to nearly everyone! For houses of worship and integrators alike, there are more bandwidth options than ever before to help make streaming into the future a PRESENT reality.
