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. Haivision’s new DMNG Manager, was 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. By streamlining DMNG operations, the solution provides broadcasters with significant time and cost savings.

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 first 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., filtering, 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 transmission reliability.

Unlicensed Wi-Fi 5GHz Band:

Wi-Fi technology is familiar to most modern computer users as a primary means for connecting computers and tablets to network infrastructure. Many consumers and businesses operate private Wi-Fi networks, and a number of providers over Wi-Fi connections in public areas such as airports, stores and restaurants.

Advances in Wi-Fi technology have driven bit rates higher over the past fteen years, making it feasible to use it for some video applications. However, before deploying these solutions, it’s prudent to analyze their benefits and drawbacks.

The 2.4 GHz Wi-Fi frequency band (ranging from 2.4 GHz to 2.47 GHz) is extremely crowded. Figure 2 shows the channels that are available – notice that only channels 1, 6 and 11 do not overlap when used at their full bandwidth of 20 MHz. The heavy trac within this frequency band is due to the great popularity of wireless connections for all types of portable equipment including laptops, tablets, security cameras, and many other devices. Also, because this band is unlicensed, there are essentially no protections that prevent another user from turning on their device and causing harmful interference at any time in any location. These factors often combine to make the 2.4 GHz band of Wi-Fi less desirable for professional quality wireless video transmission.

The 5 GHz band is a significant improvement over the 2.4 GHz band, although it is subject to most of the same technical issues. Historically, most laptop and tablet devices have not included 5 GHz Wi-Fi radios, so in general, the level of interference is much lower than at 2.4 GHz. In addition, there are significantly more non-overlapping channel frequencies available (a total of 21) in two blocks from 5.15 to 5.35 GHz and 5.47 to 5.825 GHz These factors combine to make the 5 GHz band a much better choice for professional video applications that use unlicensed Wi-Fi connections.

The latest generation of WiFi devices (including 802.11n and 802.11ac) support MIMO capabilities. This requires the transmitter and/or the receiver to use several antennas to create multiple signal pathways. The data transmitted over these channels can be added together to boost the overall transmission rate to 600 Mbps and beyond. To achieve these extreme bit rates over short distances, three antennas must be installed on both the transmitter and receiver, and the local RF environments must be relatively quiet.

As a rule, Wi-Fi systems use adaptive bitrate algorithms to ensure connectivity under rapidly varying RF channel conditions. While this is very desirable for forming reliable connections, it can cause havoc with video streams that won’t work below a minimum bit rate threshold. Accordingly, some wireless systems built for video transmission have the ability to disable this feature, but these run the risk of losing connectivity if the RF environment deteriorates too much.

Wireless Transmitter Comparison - 2.4GHz 5 GHz, 60/70/80GHz http://vidovation.com/

Each of the wireless solutions discussed in this white paper have benefits and drawbacks, and no single product will work in every situation. As a result, many broadcasters routinely use two or more different technologies, and frequently combine technologies for specialized applications. Answers to the following questions will help determine which wireless technology is the best for each potential user’s application.

1) What is the typical amount of time available to deploy the system before use? Are deployments normally made on a schedule that is known well in advance (such as for a sporting event) or is the system to be used for breaking news? The answer to this question helps determine whether or not a licensed technology can be used, and how much time can be spent to erect antennas, run cables, etc.

2) For each deployment, will the cameras be used within a relatively small area, or will a large degree of mobility be required? The answer to this question has a big impact on the types of antennas that can be used and how the coverage area is planned.

3) How often will the system be used, and for how much time will the link be active during each use? The answer to this question will help determine if a system with a monthly recurring cost or a usage cap is appropriate.
