Double your cell uplink speed in 4 or 5 easy steps

The first step is to get your modem unit higher up. The rest involves gaff (preferred) tape. :-)

Re: Double your cell uplink speed in 4 or 5 easy steps

I assume it's taped to the window Andrew? Did it stay there all the time or fall off frequently? Maybe the resonant frequency of the glass panel combined with the amplification factor of the polymer in the tape doubled the speed?

Mine has fallen off my stand a few times (light stand plus an old mobile phone car mount clip mounted on top) but it still works fine ..all the happened was the back panel fell off!

It only fell off once, which was ascribed to the heating up of the glass and tape adhesive courtesy of the sunlight.

So we fixed it by using even more tape. :-)

Interesting!

Is the doubling of speed consistent or just temporary?

Ultimately I would have guessed that the amount of local traffic to the tower dictates mobile speed/bandwidth, thereby trumping such an attempt? Or is the science telling us to get our wireless devices higher to ride more robust radiowaves (or is it microwaves :-) )?

Also interesting is your set-up there. Is that a wireless modem connected to your encoder via data cable?

A picture asking a 1000 questions. Thanks for sharing.

Re: Double your cell uplink speed in 4 or 5 easy steps

Hi Miggy,

There are a few factors in this particular instance and it kinda more than doubled.

From memory we were getting 10 or slightly more Mbps up when the modem unit was on the desk in the media box. When it was up high on the window the up-link speed went up to about 30Mbps or more. I wasn't paying too much attention at that point as we essentially had "plenty". This ensured that we could (and did) confidently stream the football matches all day in 1080HD at a full 10Mbps encoding rate.

The improvement in reception and thus data rates has also been noticed at other venues when the unit is raised in height. This just happens to be in line with the classic industry saying from FM broadcasting: "There are three things that matter ... height, height and height."

On a side note: Previously the fastest 4G data connection here (with the same unit) was about 10Mbps up. I attribute the increase in possible data transmit rates to a suspected equipment upgrade at the local cell tower since I was last there. This upgrade would have thus taken us from regular 4G technology to the 4GX (aka 4.5G) technology.

Local traffic will always have an effect, hence you tend to make a rule of running at about half of what the available bandwidth is. In this case I only set it to encode for 10Mbps as we simply didn't need anything higher. Given the upgrade to 4GX to give us those speeds, there will have also been more back haul provisioned to service it. (During the previous "4G" occasion I was at the ground we noticed up-link issues during the breaks between quarters when people would have turned to checking Facebook etc on their phones. I didn't notice any issues this time with the "4GX" connectivity.)

The ethernet cable from the wireless data modem goes back to a small gigabit switch. My laptop and the Matrox Monarch encoder are also connected to this via ethernet cable.

Thanks a lot for the detailed reply.

Will need to properly digest!!!

How do you measure your speeds? Speednet?

1080! That's impressive.

Assuming 3 hours of live streaming, that'd be somewhere around 5Gb upload in total?

Also, in terms of viewership on mobile phones, do you think your audience is opting for the 1080 or throttling back to a more conservative 480 (or 360/ 720 etc) live stream to save data?

Throttling back to watch on a phone maybe yes. But there are so much large screen smart TVs out there that I can see the need for 1080.
