First of all, I'm not talking about an active transmitter, I'm talking about a passive one - one that doesn't use power or boost the signal as such.

 

Right...

 

I live in a part of town with borderline mobile coverage. It's been this way for years, and regardless of my handset, the coverage here sucks. It hasn't normally been a massive problem until recently, since I have dropped my landline and am fully reliant on my mobile for voice at home. I can step outside and it's usable, or stand at the window facing one of the two closest towers, but since it's 2016, I don't think I should have to.

 

My mobile is with Vodafone (work phone, so no choice about the provider) and I have my broadband with Spark, hence SureSignal is out of the question.

 

So I've been doing some experiments with a passive repeater (directional antenna on one end, pointed at the tower, fed by coax to an omni antenna inside, to effectively reflect the strong signal from outside inside. So far, I haven't managed to improve my signal at all. I've tried a few different designs, all optimised for Vodafone's 952MHz, as that's what my phone is preferring to use when inside. 

 

Has anyone else tried this successfully? My outdoor antennas thus far have not been directional, so I'm thinking that the improved signal I'm getting through being outside is quickly getting eaten up by losses in the coax. If I had a higher gain outdoor antenna, perhaps things might be different. But I don't want to spend the money unless I know it's possible.

 

These guys have a product that effectively does the same thing:

Only, the phone has to be placed on the cradle, and it's overpriced for what it does, imho. It's very hard finding homebrew or DIY guides online, as most people talk about using transmitters, which we can't here. 

 

Thoughts?

With passive repeater, you will need to have phone on an inductance pad. A directional antenna will be best too. Approx what area are you?

 

 





Chorus has spent $1.4 billion on making their xDSL broadband network faster. If your still stuck on ADSL or VDSL, why not spend from $150 on a master filter install to make sure you are getting the most out of your connection?

Will Suresignal work from a non Vodafone connection?

@johnr can no doubt confirm.

I'm in Palmerston North, in the part of town that time forgot. No fibre scheduled until 2018/2019, ADSL speeds of no greater than 10Mbps, and no close mobile transmitter (at least not on Vodafone)

That is ADSL2+

On paper, I guess. Compared to the performance I see most others on ADSL2+ get, it is miles off. I'll sync at between 8 and 10Mbps, never faster.

So really you have three choices just like I did.
1. Change phone companies.
2. Change broadband isp.
3. Get in a second broadband line (naked adsl) purely to operate the SureSignal femtocell. $65 per month.

I eventually went with option 3 because Vodafone mobile coverage is vital for my work.
