a s t e r Should one fail, the bonding solution would automatically switch over to the
other connections and your stream
would not be affected.
Bonding solutions like LiveU Solo
are very handy in that they can utilize
the local Ethernet connection and a Wi-Fi connection, and you can plug in USB
LTE sticks. If you’re in the field, solutions like the LiveU Solo or the Teradek
Bond (Figure 8) or ShareLink can enable you to leverage multiple connections to deliver redundancy in delivering your stream to the internet.
Even within a single iPad or iPhone,
there are solutions. Speedify (Figure 9)
is one app/service available that puts
bonding (and a VPN) inside your iOS
device. So if you have an iPad with a
SIM card, you can have internal LTE,
plus an external LTE hotspot on a second carrier sharing Wi-Fi, and even a third source coming in through an Ethernet adapter. The bonding solution can choose one primary and then
fail over to the others. They can spread the data
across all the sources, usually increasing available upload bandwidth in the process.
2 ≠ 2
Having multiple data connections does not
automatically mean that you have a bonded
solution. If you have a phone with LTE and also
have access to Wi-Fi, that does not mean you
are using all of the different paths available to
you at the same time. iOS is designed to only
connect to one internet source at a time.
Bonding solutions are purpose-built and must
communicate with a service at the other end
to put all the pieces back together. If I use the
Speedify on my phone, some packets go over
cellular and some packets go over Wi-Fi through
the local area network. These packets are reassembled in the proper order at the other end
by Speedify. The same goes for any other bonding solutions like LiveU or Teradek.
Once you get connected, the next-most-demanded feature is the ability to send your
stream to multiple destinations at the same
time, so you click once and it goes everywhere.
All of these apps are single-destination solu-
tions. However, that single destination can be
an online service like Restream, Switchboard,
Live Leap, and others. Teradek offers its own
“Core” and ShareLink services as well.
With these, you need to set up an online account and preregister with the specific destinations you choose. Then you dive into your
iOS app and set up a manual RTMP that points
your iOS device.
