Experiences of a portable multi-cam live solutions #3 – Teradek Cube 220 and Asus NT-66u Router

I have 2x Teradek cubes, and I have to fully test them to be completely under control of these units, In todays tryout I took a Teradek Cube 220 and an Asus NT-66u router to measure the maximum Wifi distance with trees before dropping signal and without degrading video quality within the wifi range.

I did around 30 different tests some walking into the woods, and attaching a different 9dBi antenna on the router as well on the cube.

The Teradek Cube 220 is one of the oldest versions of he cubes, it does not connect to a usb dongle and it works only in a 2.4GHZ Band. On this cube I mounted a 9dBi antenna on its RF connector.

The Asus NT-66u is a reliable Dual Band 2.4/5GHZ router, It has 3x RF connectors providing me a way to attach more powerful antennas to increase its performance. On these 3x RFS I attached 9dBi Antennas.

The video signal coming from the camera and the Cube was streaming wirelessly trough the router feeding Wirecast via RTSP.

In this test I configured the Cube to send 4.5MB/s at 1080i50 to the router, I could walk up to 50m, the signal drops for 1 sec around those 50m, it was a good test, had some trees on the way and still worked as I expected.

This was a test to see till where I could walk into the bushes without signal drop, I configured the Cube to send 1MB/s at 720p to the router. I walked up 100m into the woods till I Lake, everything was better than i was expected and I didnt had any signal drop.

I will keep doing these tests over and over and some will post here.

Experiences of a portable multi-cam live solutions #2 – Car Power Inverter, Does it handle all my equipment?

Tags : 

Today I took some of my portable equipment and driven the car into a lake outside the city to test if the consumption of this equipment could be handled from a car power inverter 150w connected to the cigaret lighter.


I mentioned in the previous post, that I use a Bond device from Teradek, this unit combines up to 5 different usb dongles from internet providers giving me more stability in my live streaming at outdoors.
I took this Bond and a Cube 255 from Teradek plus an Rack box of 8Units which is mainly used for audio mixers, inside this rack was a Television Studio switcher, a dual monitor Smartview Duo and Hyperdeck Studio for replay and uncompressed recordings, plus a RME UC Fireface Soundcard to route my independent audio sources. Apart from the rack I had brought a few cameras, converters, cables and a Macbook Retina.

Before going out into the field with the multi-cam portable setup I had to calculate how many watts I would be consuming from my 150w car inverter.This will probably wouldn’t work with all the equipment powered up, which is overheading up to 200W in tottal, but I didnt dare to overhead and used some devices like the cubes and the laptop on batteries.

I made a calculation based on what is writen on the transformers as well at the specs of each device, the information is the following:
MacbookRetina – 85W
RME UC – 24 W
ATEM TVS – 20 W
Smart Viewer – 20W
Asus Router – 30W
Cube – 4W
Bond – 1W “without dongles”
Hyperdeck Studio ? – 20W

The power worked pretty well with no fails for almost a 2 hour test run, I would eventually buy a external battery power pack from Duracell to use with other devices which are exceeding in this setup the 150w, devices like the laptop, antena boosters, router etc. This power pack would also give me a backup solution in case that I see it’s draining to much battery from the car.

Another thing I just discovered during this test, was that the HDMI out port of the Macbook Retina was not detecting any signal.
I’ve researched this later back home and found out that one of the last OS update brings this issue up, in which is fixed just by restarting the computer and yes it works with a restart.

 

 

This was a good learning test for various reasons , it was raining, I had to think different forms to not get rain into my equipment, for moments I even had to lock myself inside the car.

One of the upcoming investments would be a rain cover tent.
