WHY DO I NEED BONDED CELLULAR?

One of the most critical challenges for broadcasters today is arriving first on the scene of a breaking news story and being able to send live video coverage. Tough competition between TV channels, combined with the fact that consumers are demanding news faster and on multiple devices, means that broadcasters must have reliable, cost-effective, and portable video uplink solutions at their disposal.

Flexibility is especially important today. As the number of available networks continues to grow, broadcasters need to be prepared for any situation. Choosing a system that supports a wide range of networks, including 3G/4G cellular/wireless, WiFi, Ethernet, and satellite will guarantee that a broadcaster can air live news from any location around the world.

Ease of use is also important and will enable a news organization to react to breaking news. A video uplink system that has been designed with the user in mind will include features like automatic recognition technology, which detects real-time network capabilities and bonds together multiple IP-based networks, as well as a touch-screen interface for simplified configuration and operation.

Additionally, for larger news operations, the ability to monitor and manage an entire fleet of digital mobile newsgathering equipment is an extremely advantageous piece of cellular bonding. Keeping this need in mind, AVIWEST’s new DMNG Manager, will be launched at IBC2014. It is a live video contribution platform that enables control over a wide range of equipment including DMNG transmitters, smartphones using the DMNG APP, and DMNG Studio receivers, allowing broadcasters to easily allocate resources and route live video content for transmission over 3G/4G cellular wireless, WiFi, Ethernet, and satellite networks.

While cellular bonding used to be a technique that was only used by major news organizations, today it is pretty commonplace. Nearly all TV news channels report on live events and breaking news situations using mobile cellular bonding technology – even smaller, local broadcasters. Improvement of networks and technology advancements for cellular bonding solutions has been critical in the development of cellular bonding mobile newsgathering.

In terms of the networks, we’ve seen mobile network capabilities expand from 3G to 4G and beyond, with 5G on the horizon. As consumer demand for high-speed data and high-quality video services have gone up over the years, there has been an increased need for fast broadband Internet access. AVIWEST solutions work by detecting and aggregating multiple IP-based networks (e.g., 3G, 4G, WiFi, Ethernet, satellite). As wireless connectivity increases, the AVIWEST solutions will enable broadcasters to take advantage of every IP network within their immediate area as they become available. This is achieved through a high-performance mechanism that automatically senses and bonds together all possible IP connectivity, providing broadcasters with the biggest pipe to spread their video content.

In terms of the enhancements that have been made to cellular bonding solutions over the years, some of these include more robust performance, decreased power consumption, compact size, and lighter weight. All of these improvements aid broadcasters’ ability to move faster as they are not bogged down carrying heavy equipment. The reduced power consumption also helps to decrease operating costs.

Over the years, flexibility has dramatically increased in the field of cellular bonding. In the past, broadcasters and video professionals relied more on traditional satellitebased systems for live news and events coverage; however, these systems can be limited in their scope. With a satellite-based system, users need to keep the ENG camera close to the vehicle or they will not be able to receive the signal. Using these systems, mobility and indoor coverage are nearly impossible unless a complex and costly infrastructure is set up. This approach is not ideal in scenarios where broadcasters need to cover breaking news.

For example, to broadcast the Tour de France live using a traditional satellitebased system, one would need a helicopter, an airplane, and a satellite base station. This kind of system is heavy, costly, and complex. Therefore, we generally only see such systems being deployed for a small percentage of major sports events in the world.

Thanks to recent technology advancements, cellular-based systems offer broadcasters and video professionals the fl exibility to broadcast live events in areas that are well covered by 3G or 4G networks. A portable bonded cellular transmitter, coupled with a high gain cellular antenna array, improves signal resilience and the quality of the live video transmission, providing users with a powerful solution for covering live events, such as a marathon or a cycling race, from a motorcycle. By enabling broadcasters and video professionals to more effectively broadcast news on the go, cellularbased systems dramatically change how the industry covers remote events in a way that couldn’t be imagined even a few years ago.

With 3G or 4G networks being deployed widely, we believe that cellular uplink devices are a futureproof solution that allows easy, affordable coverage of breaking news stories or sports events anytime, anywhere.

Being able to maintain a high video quality from remote corners of the world can be challenging, but not impossible. It requires mastering three types of technologies. The fi rst is network bandwidth. Broadcasters can get the most amount of bandwidth by bonding together all available networks, such as WiFi, 3G/4G, and satellite, and then adapt the video compression according to those available networks, in real-time. The second technology that comes into play is video compression. Advanced video compression technologies (e.g., H.264 and next-generation standards like HEVC) and pre- and post-processing tools (e.g., fi ltering, video concealment process, etc.) are needed to reduce the required bandwidth for a given video quality level, and improve the quality of experience for viewers. Finally, video contribution is key. The transmission must be robust in order to handle possible errors and packet loss. FEC and packet retransmission are the most common features to implement to improve the transmission reliability.

HD VIDEO TRANSMISSION

• Adaptive Bit Rate (ABR) of the H.264 video encoder.

  • This mechanism adapts the video encoding rate continuously according to the changing network conditions. Taking into considerations the continuous real-time measurements of the performance of every available link, the user’s resolution and latency requirements, cellular channel behavior and other parameters, ABR reduces or increases the H.264 video encoding rate. The result: a real time video rate adaptation mechanism that optimizes the encoding process on-the-fly.

• Error handling mechanisms:

  • In wireless and cellular environments, packet loss and errors are common inherent phenomena. Adaptive and predictive Forward Error Correction (FEC)  mechanisms at the video application level are employed as needed for each specific operation conditions.

HIGH PERFORMANCE BONDING ALGORITHM

AVIWEST’s solutions work by detecting and aggregating (i.e., bonding together) multiple IP-based networks (e.g., 3G, 4G, WiMax, Wi-Fi, Ethernet, satellite). As the world becomes increasingly covered in wireless connectivity, our solutions enable broadcasters to take advantage of every IP network in their immediate area as they become available. To perform this crucial task, a high-performance mechanism automatically senses and bonds together all possible outlets of IP connectivity to provide broadcasters with the biggest pipe to spread their video content.

RADIO FREQUENCY EFFICIENCY

In order to ensure high-quality uplink transmissions, our DMNG systems and custom high-gain antennas maximize the energy transmitted by modems based on CDMA and LTE frequencies and their associated bandwidths. The VSWR (Voltage Standing Wave Ratio) is tuned to obtain best-in-class RF efficiencies, while the use of multiple modems in a reduced space creates coupling between antennas so that the quality of isolation becomes a primary preoccupation. Through the latest software tools for antenna simulation, RF analysis equipment, and periodic measurements in anechoic chambers, our solutions are guaranteed to operate optimally, in any conditions, at all times.

SAR COMPLIANCE

The Specific Absorption Rate (SAR) measures the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field.

In the United States, the FCC requires that wireless communication devices such as smartphones and handheld tablets have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over a volume containing a mass of 1 gram of human tissue. According to the European Union standards (EN 62209-2-2010) the SAR limit is 2 W/kg averaged over 10 g of human tissue.

AVIWEST is committed to ensuring that its solutions successfully pass the SAR measurements and can be safely used while touching the body. All of our solutions have passed SAR measurements performed by an approved European laboratory. The reports are available to customers upon request.
