Receiving Loud and Clear
As 5G connectivity is deployed worldwide, bonding will remain
a critical resiliency technique for wireless cellular applications,
writes Contributing Editor Adrian Pennington...

A

few years ago the SNG market
was core business for many
contribution providers, but bonded SIM
technology has changed the game for
newsgathering. Though mainstream
adoption of 5G is still years away, the
potential benefits are tantalising,
and the TV and film industries will be
among the biggest beneficiaries.
With speeds of up to 10Gbs, there
will be virtually no delay in relaying
signals. 5G will help producers replace
costly on-site broadcast facilities
with a lighter footprint in terms of
equipment and personnel.
Wireless camera technology will be
increasingly used on reality and live
entertainment shows too reducing
and eventually eliminating, cabling
and fixed lines. Cameras linked to
4G cellular networks are widespread
today, but are unreliable and in
competition with public traffic. 5G
guarantees connectivity, achieved by
network slicing - the assignment of a
dedicated piece of spectrum.
As 5G connectivity is deployed
worldwide, bonding will remain a
critical resiliency technique, for
example during build-out, in remote
areas and where 5G falls back to
existing frequencies. Cross-company
bonding will also be important in
cases of network failure or to ensure
network coverage with performance
depending on users' proximity to
cellular towers and antennas.
There is a fly in the ointment.
Broadcasters and production teams
currently use radio spectrum on a
daily basis to produce both recorded
and live content. Throughout the
production chain from radio mics to
satellite contribution spectrum will
be impacted by telcos demanding
spectrum for 5G rollout.
Policing
this
on
behalf
of
broadcasters will be the 5G Media
Action Group (5G-MAG) which is run
by the EBU. It aims to develop a way
of combining unicast services with
multicast services and even a satellite
overlay network.
TVU One 4K from TVU Networks
is the current top-of-the-range of
its mobile transmitters. This model
features a H.265 hardware encoding

TVU One 4K is 5G ready

chip and can deliver full broadcast
quality 4K, 10-bit true 60 fps HDR
video at 3Mbps with Inverse StatMux
Plus technology. 4K P60 HDR video
can be transmitted with 0.5 second
latency, according to TVU. Real-time
dual encoding makes it possible to
go live under any network conditions
by simultaneously recording a full
HD/4K copy of your live video for later
download. This unit is also equipped
for 5G.
Dejero's 5G-ready mobile transmitter
EnGo 260 is for news contributions. It
supports 20Mb/s encoding and 1080p
50/60 and uses a combination of
hardware and software encoding to
provide an efficient way to deliver the
best picture quality.
The company is a recent recipient
of its second technical Emmy, this
time for a patented Smart Blending
Technology (used in EnGo 260)
which aggregates multiple network
technologies, including cellular and
satellite, from multiple network
providers to create a virtual 'network
of networks' that delivers enhanced
reliability. Onboard content adaptive
encoding adjusts the encoding process
based on the amount of motion in the
live shot to improve picture sharpness
in challenging network conditions.
Camera operators can automatically
transition from a limited motion
talking-head shot to a high-motion
shot without any softening of the
picture or introduction of compression
artefacts.

The mobile transmitter's hybrid
encoding (also Emmy cited) is said
to balance performance and power
consumption and enables easy remote
updates to transmitters deployed in
the field. Advanced RF design with
optimized
antenna
performance
results in a stronger and more reliable
signal from cellular towers.
LiveU's flagship LU600 solution
for ENG and live sports coverage has
integrated a 5G modem. Combined
with high efficiency antennas covering
all sub 6GHz frequencies for 5G and
4G and using the firm's version of 4K
HEVC, the LU600 5G offers a futureproof cellular transmission solution.
Samuel
Wasserman,
LiveU's
CEO & Co-founder, says: "Our new
LU600 5G solution with integrated
5G modems takes full advantage of
the faster speeds and guaranteed
high bandwidth provided by next
generation 5G networks."
Many aspects of technology are
rapidly converging to enable remote
productions to get faster, more
economic and, ultimately, more
exciting for consumers. Into this field
comes Broadcast Wireless Systems
(BWS) showcase of remote production
capabilities in which its low latency
NanoPRO TX camera-back transmitter,
was demoed with Hitomi's 'Matchbox
Glass' iOS app. MatchBox is an audio
video alignment toolbox.
"As broadcasters need simple
and reliable RF transmitters to
move content, they similarly need
a quick and accurate way in the

Dejero's EnGo

LiveU's LU600 portable
transmission unit

field to ensure sync, including for
multicamera productions," explained
Hitomi Broadcast Director Russell
Johnson. "So long as they have a
MatchBox Glass-equipped iPhone
or iPad, production teams can now
easily measure and correct for latency
differences between cameras on site,
which is especially useful for remote
productions."
Benefits include the ability to
instantly measure latency and provide
fast, accurate lip-sync and alignment
of multiple cameras.
Among other innovations from BWS
is its proprietary Sapphire Codec for
handling HEVC. The Sapphire system
compresses a single 4K UHD input or
up to 4 HD inputs in one unit. Each
input can support two stereo pairs of
embedded audio. Compressed streams
are available as IP or on DVB_ASI for
interoperability. It's available for
flyaway, SNG or ENG applications, or
in a Clip-On configuration where it
can work as a complement to existing
wireless camera solutions.
Vislink Technologies new MicroLite
3 is a small (3in/9cm) wireless camera
transmitter for capturing real-time HD
1080i video compressed in MPEG-4
from cameras used in applications
such as ENG, live sports, Steadicam
operations and drone-based coverage.
It supports Vislink's proprietary
LMS-T, a modulation technique that
allows greater payload capacity over
equivalent bandwidth than DVB-T
options, Vislink claim. Vislink has
increased the frequency range of
the product to include licensed and
unlicensed frequencies from the 2GHz
to 6GHz range. Also included is a
telemetry channel providing
