Are You Ready For The Era Of Private Wireless Networks?

Blog Category: by

Written by Steve Carroll

In the next four years, Ericsson predicts that North Americans’ data consumption will increase by 500% per user. In 2026, the average user is expected to consume 48 GB of data monthly by 2026.

Much of this data consumption will occur over carrier networks—the networks that support mobile/cellular connections. Today, mobile networks carry almost 300 times more mobile data traffic than they did in 2011. And the vast majority of this traffic—80%—is now consumed indoors.

What does this all mean for the buildings where the data is consumed?

Adapting properties to support growth in dedicated in-building wireless will be key to keep employees, visitors and guests connected indoors. In fact, many buildings are now being evaluated based on the technology and connectivity they offer to their tenants and occupants. We’ll share more about this concept in a future blog, but there are certification programs that rank new and existing buildings based on their digital infrastructure, future readiness and user connectivity experience. One of the newest categories ranks the in-building wireless capabilities of a facility.

Poor indoor mobile connectivity isn’t something that can be overlooked any longer. But, many times, the building itself prevents a wireless carrier’s cellular signals from coming inside. Material like metal, tinted glass, brick and concrete act as physical barriers that slow down or prevent signal penetration.

In the past, mobile carriers were big investors in wireless infrastructure. If they knew their customers would be located in or near a venue—a high-rise office, arena or shopping district, for example—then they would help fund that facility’s wireless infrastructure to provide customers the best experience possible indoors (sometimes even paying a monthly fee to rent space for the infrastructure). In many situations, it didn’t cost the owner much money to deploy a mobile network.

Today, this approach has changed. Because most carriers no longer have the budgets to continue operating this way, enterprises now have to provide their own in-building wireless. As owners take on these costs, they’re looking for other connectivity options—such as private wireless networks.

In future blogs, we’ll talk about where private wireless networks work best, how they may be positioned to support emerging technology initiatives and best practices to design and deploy private wireless networks. For now, we want to explain what private wireless networks are—and how they’re different.

 

What Is A Private Wireless Network?

The purpose of a private wireless network is to give individuals or organizations the chance to deploy their own connectivity systems. These systems can operate by leveraging a combination of licensed, quasi-licensed and/or unlicensed spectrum. In other words, they can be LTE (the technology behind 4G) or 5G networks. They’re owned and operated by an enterprise, not a mobile carrier.

Globally, each region of the world is at a different stage of enabling its own access to private wireless spectrum. In the United States, private wireless networks can operate within the (CBRS) Citizens Broadband Radio Service and C-Band spectrum.

The CBRS frequency range spans between 3.5 GHz and 3.7 GHz and is licensed to the U.S. Department of Defense.

In 2015, the U.S. Federal Communications Commission decided to make this spectrum range available to a wider variety of users. The spectrum is “shared” between these groups and governed by the OnGo™ Alliance, a coalition of industry organizations focused on shared-spectrum solutions.

 

Why Are Owners Choosing Private Wireless Networks?

There are many reasons why an owner may be considering a private wireless network. One of the biggest reasons has to do with costs, like we mentioned above. In some cases, like in highly populated areas, carriers may continue to help fund infrastructure. In situations where they can’t or won’t, owners will be looking for cost-effective ways to bring mobile connectivity into their buildings.

Other reasons involve privacy and security. In a public network, data traffic travels back and forth to a central network in another location. Private wireless network traffic doesn’t have to do that. This not only improves security and privacy, but also lowers latency and improves speed.

Private networks also allow enterprises to control their own bandwidth distribution. A smart manufacturing plant, for example, may choose to prioritize connectivity for its latency-sensitive production lines over back-of-house systems.

 

Where To Learn More About Private Wireless

Recently, Belden teamed up with Ranplan to lead a discussion on the topic of private wireless.

If you missed it, you can watch Private Wireless Networks Explained on demand. We walk through the basics of private wireless so that you understand its capabilities and benefits in terms of deployment, bandwidth, maintenance and costs.

Because every situation is different, private wireless may not be the exact fit to replace a distributed antenna system (DAS). Belden can help you determine your specific connectivity needs.

Reduce Data Center Operating Costs to Improve PUE

Blog Category: by

Written by Shad Sechrist

Data Centers

If you’re looking for ways to reduce data center operating costs, then lowering monthly energy bills is a great place to start. By far, the biggest contributor to high data center operating costs are these recurring expenses.

 

What drives your utility bill so high each month? In most data centers, it comes down to the operation of non-IT systems:

  • Cooling and air handling
  • Lighting
  • Security cameras

 

To determine how much of your total power usage goes to systems that don’t provide compute services, you can calculate your data center’s power usage effectiveness (PUE). This ratio compares the total amount of power used by your data center to the amount of power delivered to its computing equipment. It also reveals how much energy is used for non-IT activities and systems.

 

PUE = total facility power / IT equipment energy

 

A high PUE indicates that your data center uses more power than it should to run equipment. A low ratio suggests that energy is used effectively to get compute work done.

 

As we examined the Uptime Institute’s 11th Annual Global Data Center Survey, we discovered that energy-efficiency progress has slowed down for many data centers.

 

From 2003 to 2010, for example, the data center industry made great strides in improving PUE. The average data center dropped from 2.5 to 1.6. In the last five years, however, the industry hit a plateau. The average PUE has been stagnant, sitting near 1.56.

 

When this PUE is translated to a percentage (by using the data center infrastructure efficiency [DCiE] metric), it shows that approximately 60% of energy entering the data center is used to power the non-IT systems we mentioned earlier—not the compute gear.

 

Newly constructed data centers designed to maximize energy efficiency typically see PUEs of 1.1 or 1.05—proof that this level of performance can be achieved. And while there’s plenty of new space on the horizon, most data centers have been running for years and rely on older systems.

 

Why is PUE Progress Slowing Down?

By now, most data center managers have had time to pick the low-hanging fruit, such as:

  • Isolating supply and retain air through containment walls or using end-of-row doors on aisles to prevent air mixing.
  • Using blanking panels to fill unused “U” positions in racks or enclosures and separate hot and cool air.
  • Sealing holes in walls and raised floors with plenum-rated products.
  • Replacing missing or poorly fitting floor tiles.
  • Getting rid of underused or non-operational servers.

 

If your data center hasn’t implemented these best practices, now’s the time to do so. You’ll see an immediate improvement in energy use and lower data center operating costs.

 

The next phase of efficiency improvements, which can take PUE from 1.5 to 1.2 or 1.1, requires more time and money. Once you pick all your low-hanging fruit, here are some examples of what’s waiting higher up the tree.

 

Deploy Power Distribution Units (PDUs)

PDUs are like well-constructed power strips designed to be used in data centers. Today’s smart PDUs help data center managers remotely monitor power use, energy efficiency and environmental conditions.

 

They can track metrics like real-time power usage, data and event logs, the amount of current drawn by each PDU and the amount of current drawn by each outlet so you can optimize usage down to the device level.

 

This level of granularity is key. When you know exactly how much energy certain systems use, it becomes obvious as to where changes need to be made—even down to the rack level.

 

Install More Efficient Cooling Equipment

If you want to replace your legacy cooling equipment with new, more efficient systems to better control heat, there are many options to choose from. The right one for your data center depends on its size, location, configuration and unique design challenges.

 

You can choose to cool at the room level, the row level or the rack level (or use a combination), and there’s a long list of systems to choose from: computer room air conditioners (CRACs), liquid cooling and precision cooling are just a few examples.

 

If your cooling equipment is outdated, then it’s likely inefficient. Upgrading your system can reduce energy use and lower data center operating costs.

 

Invest in White Cabinets

Lighter-colored cabinets can conserve electricity in a few ways. Light colors like silver or white naturally reflect more light than dark colors (like black) because they have different light reflectance values (LRVs). For this reason, additional lighting is often needed to see labels and ports among dark cabinets.

 

When you lower lighting levels, you also reduce the amount of heat given off by the lighting system, which reduces cooling requirements. We estimate that swapping black enclosures for a lighter color leads to energy savings of between 1% and 2%.

 

Update Lighting

Modernize your lighting systems to take advantage of LED technology. LEDs are a good fit for data centers for many reasons:

  • They generate less heat than fluorescents, which translates to lower cooling costs
  • They use less energy than alternatives
  • They offer lighting uniformity so all areas are equally bright, reducing shadows that make maintenance work difficult

 

Occupancy sensors and lighting zones are also effective ways to control data center operating costs. When no one’s in the data center, the lights will automatically shut off. (Depending on your surveillance equipment, you may need enough illumination for proper video capture, but many of today’s cameras can see in low-light and dark conditions.) When the lights are on, initial entry areas and halls don’t need to be as bright as equipment areas, and they can be zoned accordingly.

 

Keep People Out of the Data Center

Data centers spaces are built to process data, not host people. Keeping the data center as “hands-off” or “lights-out” as possible is another step you can take to reduce data center operating costs.

 

IT equipment can operate at higher ambient temperatures than those typically comfortable for people. If you can automate certain processes and reduce the need for onsite staff, then the space doesn’t need to be as cool.

 

Lights-out data centers may not be common yet, but COVID-19 revealed what these unmanned spaces may look like. In many cases, the examples proved that data centers can operate with little human involvement.

Three AV Trends To Watch

Blog Category: by

Written by Bob Ferguson

You can be an innovator instead of trying to play catch-up when you know what AV technology is coming—and where it may show up. Here’s a short list of what we’re hearing about when it comes to AV trends and the future of the AV industry.

 

Three AV Trends To Watch:

#1: Technology for Hybrid/Hyflex Spaces

It’s no surprise: The future of the AV industry includes the pivot of work and education to hybrid and online approaches, addressing the practical and logistical challenges of bringing everyone together in person.

According to Statista, nearly one-quarter of K-12 schools rely on hybrid learning. Inside Higher Ed says that three-quarters of college students want to take online courses; 68% are interested in hybrid options. A recent Accenture report reveals that 63% of high-revenue-growth companies embrace hybrid workforce models, and 83% of workers prefer that model as well.

Technologies that can sustain seamless collaboration and productivity in environments that support face-to-face and online interaction will continue to be in demand.

For example:

Streaming rooms equipped with monitors and videoconferencing platforms for team meetings that involve in-office and remote teammates.
Videoconferencing “booths” or huddle rooms for one-on-one hybrid meetings and small impromptu brainstorms.
Interactive learning tools that can support things like polling, chat, screenshare, and virtual breakout rooms.

 

#2: Wireless Integration

Everyone has become accustomed to the ease and simplicity of wireless connections. With the opening up of the radio spectrum, bandwidth availability has increased dramatically. This additional bandwidth makes wireless an option to support AV applications, and this trend will only continue to impact the future of the AV industry.

Cellular services with 5G bring higher speeds, lower latency (faster responses), and the ability to connect more devices simultaneously without any problems. Through advanced antenna technology, 5G enables much higher levels of data transmission over systems by boosting bandwidth. You can increase this coverage by extending cellular coverage into your building.

Wi-Fi 6 and the 6 GHz band also open up a new spectrum that wasn’t previously part of the unlicensed spectrums. The IEEE 802.11 working group has already released a new standard to take advantage of this new 6 GHz band. It’s called Wi-Fi 6E, an extension of Wi-Fi 6. Wi-Fi 6E devices will operate in the 6 GHz band, giving them access to four times the amount of bandwidth currently offered by Wi-Fi in the 2.4 GHz and 5 GHz bands. As this is adopted in the AV industry, look for AV devices that will take advantage of these benefits.

 

#3: Continued AV over IP Adoption

Legacy AV systems were designed around input devices (like microphones) and output devices (like speakers). To get systems to work together, other specially designed electronics were necessary to process signals and direct them to the proper location.

AV over IP overcomes many of these challenges by transmitting AV data over a network or the internet. It’s also cost-effective and easily scalable. For this reason, we see the continued growth of AV over IP as another trend that will persist in the future of the AV industry.

AV signals have become digital signals (0s and 1s), and one of the most efficient ways to transmit these 0s and 1s is with Ethernet packets. It isn’t idiotproof yet, but systems have come a long way in addressing latency and bandwidth concerns.

In addition—whether on their own network or part of the building network—AV systems can now take advantage of network diagnostics to troubleshoot problems and reroute signals to keep AV systems up and running.

The other huge advantage of AV over IP is its flexibility and adaptability to change. For example: If you need a flexible space that can accommodate lots of applications, then you can cable the room with Category 6A cabling. From there, changing a patch cable in the telecom rack can deliver AV input or output and even low-voltage power anywhere there’s a jack.

 

Supporting These Top AV Trends

Don’t let the least expensive part of your AV system be the cause of most system failures. Remember: The success of these AV innovations—hybrid working and learning, 5G/Wi-Fi 6 device integration, and AV over IP—depends on network infrastructure. Increasing numbers of users and devices (wired and wireless) mean that bandwidth and capacity will matter even more to support new technology and applications.

No matter what type of technology is deployed (videoconferencing, unified communications, workplace management apps, etc.), it needs to be supported by high-performance cabling and connectivity.

Not all cables are created equal, so pay attention to the specifications of the cable you select for AV. To ensure excellent performance, you should choose cable from a trusted and respected brand, follow recommended installation practices and use high-quality connectors.

Coaxial Cables – What are they, and how are they used?

Blog Category: by

Written by Krista Thresh

What is a Coaxial Cable?

Coaxial cable is a type of cable that has an inner conductor surrounded by an insulating layer, surrounded by conductive shielding (outer conductor), and a protective outer jacket. Electrical signal flows on the center conductor.

 

How is a Coaxial Cable used?

Coaxial cable is commonly used by cable operators, telephone companies, and internet providers worldwide to convey data, video, and voice communications to customers. It has also been used extensively within homes.

Coaxial cable has been around for a long time as a technology (since the early 20th century) and has many singular advantages for reliable, accurate transmission.

It also has limitations that will cause it to be replaced in some cases by fiber optic cable, category cable or, sometimes, by wireless signals.

The key to coaxial cable’s success has been its shielded design, which allows the cable’s copper core to transmit data quickly, without succumbing to interference or damage from environmental factors.

 

What are the two most commonly used Coaxial Cables?

The two most commonly used coaxial cables are RG-6 and RG-11:

  • RG stands for “radio grade”, they are also known as RF cables, which stands for “radio frequency”
  • RG-6 cable is used for drops shorter than 45m
  • RG-11 cable is used for longer drops due to the increased performance over lengths more than 45m
  • Broadband cables used in homes have an impedance of 75 ohms

Coaxial drop cables are most commonly terminated using connectors that are designed to the F-type interface specified by SCTE. Over the years F-type interface has evolved significantly, resulting in several different termination technologies including crimp, screw on, and compression.

To make a connection, a male and female connector of the same type is necessary. Male connectors have a center conductor or pin sticking out, depending on the drop cable type, while female connectors have a receptacle for the center conductor or pin to interface with.

In cases of improper termination craft, damaged materials, or loose connections, it’s good to be aware that the result may be signal ingress or egress. This may cause tiling, fuzzy or snowy signals, or even complete signal loss.

 

The benefits of Coaxial Cables?
There are many benefits of using coaxial cables, but determining whether this cable option is viable for you, depends highly on what the cable can do.

  • Can be used for carrying video, audio, and other forms of data
  • Work better for shorter distances
  • Easy to install
  • Very durable
  • Best suited for home installations or medium-capacity data transfer networks
  • Cost effective

Blog Category: by

ERVITAL JE-H(St)H…Bd FE180/PH120

Fire alarm systems sit quietly in the background of connected infrastructure as people go about their daily lives. Shopping centres, hotels, offices, airports, and other types of transportation terminals are all responsible for the safety of the people that pass through them. Therefore, sophisticated fire alarm and suppression systems are required to ensure real-time dangers are alerted and addressed immediately.

In the event of a fire these critical safety systems must continue to operate, and this is where fire resistant or ‘circuit integrity’ cables play an important role. Circuit integrity cables connect sensors, alarms and other components of the fire alarm and suppression systems and feed information back to control centres.

There are a wide variety of standard and approvals required depending on the country and region, the application and environment, and at times the also the end-customers design and preference. Ensuring system integrators and contractors both select and procure cables that meet the required standards and approvals and perform accordingly is key to protecting your investments. Low-grade cables manufactured to reduce costs and that are purchased from unknown sources may not perform as expected. To safeguard against this make sure to request a copy of the test certificates specific to the cable batch your purchase came from.

The ERVITAL JE-H(St)H…Bd FE180/PH120 fire alarm cable from Erse Kablo, is manufactured with safety and quality in mind, and meet both local and international flame test standards and approvals, IEC, VDE, EN, and BS EN standards.

Digital Electricity – What you need to know

Blog Category: by

Digital Electricity – What you need to know 

Digital Electricity is a new way to safely distribute high-voltage power over long distances by combining data and DC power into packets that are transmitted and received, similarly to how data packets travel over enterprise networks. It transfers high levels of power over non-power cable, and a complete system requires transmitters and receivers to function. These digital electricity cables are designed in conjunction with VoltServer, allowing them to support applications in various situations. Available in hybrid copper/fiber constructions to send power and data in a single cable run. Other additions to the digital electricity cable line include the hybrid cable versions for indoor and indoor/outdoor 2 mm breakout plenum cables. 

The transmitter takes in AC or DC power and sends it out on individual electrical circuits. From there, specialized digital electricity cables can be used to distribute the power. The receiver “receives” the electricity packets sent from a transmitter and converts the energy packets into the required form. 

PoE technology can carry up to 100W of power over a data cable for up to 100 m, digital electricity can carry up to 2,000W and travel up to 2km. Digital electricity is able to offer 20 times the power or 20 times the distance that’s currently available through PoE.

5 things you need to know about digital electricity: 

1. It ensures safety

By including “smart circuits” that can monitor when electricity is escaping, it’s able to immediately stop the electricity flow and continuously manage the flow within the circuit to ensure that electricity is flowing to the right places safely. In the event of an issue, the electricity process will stop within 3 milliseconds, which is fast and secure enough to prevent injuries or danger. With its class 4 systems, it makes the digital electricity cables just as safe, if not safer than class 2 and class 3 systems. 

2. It allows for ample power 

Digital electricity cables can be run through existing cable trays to double or triple the amount of power brought to the equipment. These cables can deliver power across long distances and are known to be 20x more powerful or can go 20x more distance than PoE with 2000W across a reach of up to 2km. 

3. It provides a back-up 

In the event of an emergency, the transmitter can run critical power to wherever it is needed, including wireless systems so operations can still be run when power is no longer available. 

4. It simplifies cable installation 

Due to how energy is handled within these systems, installation of digital electricity cables doesn’t need to be installed by an electrician which makes the installation faster and more cost effective. These cables are easy to relocate and reuse without leaving stranded outlets or conduit behind, as current Class 4 certified cables include the DEDN and DEWN product families. The cables have a stranded copper pairs design which maintains flexibility and performance during instillation, thus also improving electrical performance. 

5. It enables new applications 

Digital electricity allows power to be run much longer distances with less voltage drops and without dealing with large copper wires, allowing opportunities for other applications to be created and used. These cables are ideal for distributed antenna systems, passive optical networks (PONs), security cameras and wireless access points; can be used for indoor (plenum and riser), outdoor and overhead-burial applications.

SDI – How Far Can You Run?

Blog Category: by

Serial digital interface (SDI) video signals, the uncompressed, unencrypted digital signals that were developed by SMPTE (the Society of Motion Picture Television Engineers), an integral part of high-definition broadcast transmissions.

Although fiber is an option, most SDI signals use a 75 Ohm coax, an industry staple in broadcast for many years. Coax has a proven track record of reliability and is easy to terminate and install, with excellent electrical characteristics that offer very good performance.

As more and more coax cables for SDI signals hit the market, broadcasters need to determine how long they can run these cables and their camera systems. To give broadcasters the info they need, Belden have created a table based on signal loss recommendations for given formats as specified by SMPTE, an updated table that features the new formats, the new versions of cables, and their maximum recommended transmission distances.

It is however important to note the bit error rate (BER) can vary dramatically as the calculated distances are approached. BER is dependent on receiver design and the losses of the actual coax used. OEM specifications should be consulted to verify their maximum recommended transmission as performance can vary based on the type of active equipment specified. Some manufacturers aren’t designing all their 12 GHz receivers to reach the maximum loss level, which could result in distance reductions of up to 50%. This variance is recognized in the SMPTE 2082-1 Standard, however, receivers designed to work with greater or lesser signal attenuation are acceptable.

The table is based on attenuation or signal loss at one-half the signal frequency as defined by SMPTE and based on signal type. The distance values are for cables only; they don’t include connectors, bulkheads or other items used to connect cables and add loss.

Video Distance Chart – https://www.jaycor.co.za/wp-content/uploads/2022/05/digital-video-distance-chart-product-bulletin.pdf

As the industry continues to move towards 12 Gb/s single-link as part of SMPTE 2082-1, it’s now critical for designers to verify distance. To do this, check with your equipment manufacturers to confirm the type of cable needed to reach the distance you want to meet. To support 12G-SDI Belden created a new series of coax cables specifically for 12 GHz bandwidth. Belden’s 4K UHD Coax Cable for 12G-SDI supports 4K content without a change to fiber. It gives designers access to the best possible performance in a coax cable sweep tested to 12 GHz signal.

While some broadcasters have switched to fiber optic cabling to achieve greater distances (JAYCOR supports these cables too), coax cable isn’t dead. In fact, there are many applications where coax is still preferred.

Ensure your broadcast performance stands out for all the right reasons. Downtime, delays, and distortion have an immediate far-reaching impact. Reliable AV cabling solutions help you achieve absolute signal integrity and 100% uptime, no matter the conditions.

JAYCOR’s Belden AV cabling and connector solutions support fast, easy assembly and maintenance while ensuring long transmission distances in all weather conditions. Drag these cables below roads, above trees, around a stadium and off and on the stage every week—they’re ready for anything.
