Embedded Antennas and the IoT

May 2, 2019 at 8:00 AM

 

In the not so distant future, the world will be fully automated with machines being able to communicate with little or no interaction from humans, thanks to the arrival of the Internet of Things (IoT) and the use of embedded antennas.

 

These small form factor antennas are a perfect fit for the shrinking size of IoT devices, while still being able to keep up with the massive amounts of data that will need to be transmitted as the IoT connects physical devices with software based management and control applications.

 

Embedded antennas are small, yet powerful antennas with many offering multiband support for use in mobile and fixed data applications. Their key performance attributes include high efficiency, low power consumption, low return loss and isolation.

 

High efficiency brings better signal reception, improving the system’s ability for faster data transfer rates. Reduced power consumption allows for increased longevity. Less return loss means more power transmitted, and isolation limits the amount of crosstalk interference. Embedded antennas can work with high-frequency or low-frequency systems, some feature MIMO technology and smart antennas have been introduced that feature embedded GPS and Flash memory capabilities.

 

As IoT deployments get underway, there are more embedded antenna options to consider to take full advantage of this exciting era of automation.

 

To help you succeed with your IoT implementations, we offer a full line off-the-shelf, embedded antennas ready to ship the same-day, plus custom designed antennas to suite all of your IoT needs.

 

12G-SDI Serial Digital Interface

April 18, 2019 at 8:00 AM

 

Serial Digital Interface (SDI) is a digital video interface that provides a range of advantages for transmitting video and audio. This long-lived standard has been around nearly 30 years and is still as relevant as ever, keeping up with the changing demands of today’s technology. Now, SDI has come out with its most powerful iteration: 12G-SDI. Let’s take a look at all of the details.

 

12G-SDI brings the SDI standard to the next level with improved resolution, frame rate and color over a single cable. Capable of 12 Gbps speeds, it delivers four times the bandwidth of HD and is perfectly suited for the 4K 60p format. This makes it ideal for live broadcasting, studio sets and venues where it’s important for a cable to maintain a strong signal while also being easy to connect and fairly lightweight. 12G-SDI is also expected to expand into fiber to increase its distance and bandwidth capabilities up to 10km and open up opportunities for 12G technology throughout broadcast and production facilities.

 

Though this standard has been under development since 2012, it has not yet been ratified by the governing body of standards, the Society of Motion Picture and Television Engineers (SMPTE). Thus, not all manufacturers have begun making products to support 12G-SDI. But those that are being made are delivering customers with cables and connectors that are simple to connect with better image and signal, and without extra weight or cost. Even without ratification, 12G-SDI is a viable standard offering real solutions for today’s video and audio demands.

 

Category 7 Overview

April 4, 2019 at 8:00 AM

 

In today’s world, the need to transfer vast amounts of data at high speeds is required. In many Enterprise datacenters, fiber is sometimes used to handle this task but the price of expensive optics and other factors might require a copper based solution.

 

Enter Category 7 cables!

 

Category 7’s most notable quality is its capability of handle speeds of up to 10 Gbps over 100 meters, especially when compared to Cat6 and Cat5e’s 1 Gbps speeds over the same distance. During testing, speeds of up to 40 Gbps have been measured over a distance of 50 meters, and up to 100 Gbps over 15 meters. And, Cat7 cables are able to deliver those high speeds at a higher frequency of 600 MHz, as opposed to Cat6a’s max frequency of 500 MHz. This means that a Cat7 cable will be able to transfer data faster than any of the previous category cables, making it an ideal option for wiring smart homes, data centers, large enterprise networks or anywhere else a high-speed wired connection is required.

 

Aside from speed, Cat7’s other benefits of note include the extensive shielding of its twisted pairs which can considerably reduce signal attenuation and improve noise resistance. The individual pairs in these cables are shielded with an additional layer of shielding over the whole cable.

 

Cat7 cables are also extremely durable and generally have a longer lifespan that Cat5 and Cat6 cables. And while Cat7 cables can be more expensive than other category cables, that price can be offset by their increased performance and resilience.

 

Cat7 has a good amount of admirable qualities and with it being backward compatible with traditional Cat5 and Cat6 cables, Category 7 might be the right choice for your next wired installation. If your application is outdoors or in an industrial environment, check out our new rugged, Cat7 cables with 10 Gig rating. 

 

Case Study: Crown Castle

March 21, 2019 at 8:00 AM

 

Crown Castle is a leading independent owner and operator of wireless infrastructure that also builds and leases towers, rooftops and distributed antenna systems (DAS) for wireless communication in large markets. They pride themselves on being able to provide comprehensive site deployment with state-of-the-art processes and tools.

 

As part of a wireless networking project for Disney theme parks, Crown Castle was facing the challenges of extreme heat and weather. They were in need of a UL-listed, weatherproof enclosure capable of supporting Power over Ethernet (PoE) with an integrated cooling fan.

 

Fortunately, L-com was able to deliver exactly what they needed by creating a customized, UL-listed, weatherproof equipment enclosure. The rugged, fiberglass enclosure featured multiple PoE interfaces, the ability to mount two wireless CPE devices and it was able to be locked for added security.

 

In the end, L-com was able to fulfill all of our client’s needs and this custom product helped Crown Castle offer seamless Wi-Fi access for customers and employees of Disney Parks.

802.3cg 10 Mbit/s Single Twisted Pair Ethernet

March 7, 2019 at 8:00 AM

 

Ethernet technologies are continuing to grow and their use continues to expand across a growing number of industries. With all of this Ethernet expansion, there has been a call to quickly identify and address the progression of standards to support wider use of the IEEE 802.3 Ethernet standard. That need has brought about the development of 802.3cg.

 

The goal of 802.3cg is to deliver 10 Mb/s speeds over single twisted pair Ethernet, up to 1 kilometer. 802.3cg also specifies one or more power distribution channels delivering 13 watts of power over twisted pair link segments, not to exceed 1 kilometer.

 

This single pair Ethernet standard is aimed to provide a comprehensive communication protocol, a shared networking infrastructure, and produce power for the growing sensor technologies that will enhance the effortlessness of Ethernet’s money saving, plug-and-play design. This standard will also focus on gaps in the existing IEEE 802.3 standards and look to fill them, and it will work to build a focused, industry-approved plan for developing proposed standards. Additionally, the IEEE 802.3cg working group will determine what Ethernet standards need to be developed in order to support the wide range of products now depending on Ethernet.

 

Defining Ethernet standard requirements will extend Ethernet’s reach and there are several industries that could see significant growth. These include the automotive industry that is already using Ethernet for vehicle cameras, security systems and diagnostics, and is moving towards driverless technology that is Ethernet dependent as well. Plus, smart city technology that is becoming more popular throughout the world utilizes Ethernet, and that trend towards sustainable, connected living is expected to continue to grow. And, of course, the data centers that we all depend on to keep us connected depend heavily on Ethernet connections. In turn, Ethernet has the opportunity to innovate the data centers with the development of the 802.3cg standard and beyond.

 

The 802.3cg standard’s ability to provide 10 Mb/s speeds over single twisted pair Ethernet is a welcomed progression in the evolution of Ethernet and another sign that Ethernet has no intention of slowing down.
