Default Cheap phone as hotspot?

Hi all,

We have need to get Internet access on some portable kit (Netbooks,
iPad etc) and the mobile signal isn't very good in that area. So, I
was wondering if something like a basic mobile phone (Android?) would
take my Voda Prepaid SIM from my Voda USB dongle (I think that's what
is is ... it's still got 13 of the 15 credit it came with a few
years ago) and then stick the phone in a plastic bag at the top of a
long pole. ;-)

(This is only a temporary / experiment / solution so the Heath
Robinson approach will be fine). ;-)

Other times it might be used *** a hotspot in the car or where there
isn't any other wired broadband connection so less 'radical' as such.

So, anyone know what might be a good choice of phone for this please?
I know I could get a MiFi or similar but I was thinking a phone would
be more compact and could also be used as a phone if required.

Cheers, T i m

p.s. Son in law has a Blackberry with some data allowance, can they be
turned into hotspots do you know please?

Why not stick the dongle complete with USB lead up the pole?. Seen it
done and much easier to power switch on an off etc. You can then connect
that into a router and provide for more then the one PC if required ....

Or somewhere on the Solwise website they do, ISTR, a router that has an
external aerial connector and built in receiver/router gubbins...

But you can only go a few metres this way.

OTOH an aerial cable would have unacceptable losses at 2G4Hz.

No, you put the dongle or router whatever gubbins up at the top of the
pole. Then run either USB or CAT 5 from that down the pole. The 2.1 Ghz
aerial is right next to the dongle or router unit at the top of the pole
then that has minimal losses because of the short cable length involved.


Bin there and dun it for an installation right out in the sticks. The
site was surrounded by very leafy trees that were clobbering the 3G
signals. Now that a more efficient aerial system could be used and the
aerial was in an "unobstructed" place, it worked very well.

This unit was in a sealed plastic case some 20 meters above ground>..

Erm, I've tried that with my Zoom 4501 with both active and passive
USB extension leads and it rarely seems to work. I thing the Voda /
Huawei E220 dongle must draw quite a bit of current or something
because I tried it on a 6" USB extension earlier and it wouldn't
connect on the 3G side.

>You can then connect
>that into a router and provide for more then the one PC if required ....


Yes, that would be good solution for down Mums holiday mobile home but
not so good when in the car or camping. ;-)

Cheers. I've had a quick look and can't see anything that isn't quite
expensive (or more than an Android phone or Zoom Model 4506 (battery
powered) and USB dongle) or less flexible.

This would be perfect for example:

http://www.solwise.co.uk/3g-routers-...-aap-2410m.htm

This would be cheaper and easier for 'up the pole':

http://www.solwise.co.uk/3g-dongle-lp1917e.html

But is *only* 3G and I think I understand that it might be easier to
get 2G in some locations (assuming that is also 'Data' etc)?

This could be good but doesn't look like it supports my T-Mob / ZTE
120 USB dongle. ;-(

http://www.solwise.co.uk/downloads/f...ongle-list.pdf

As an experiment I might make up a 4.8V battery pack (I have some 3A
NiMh cells kicking about) for my Zoom 4501 and stick that on the pole
to start with. ;-)

As luck would have it mate came round today who bought a T-Mob
'Pointer' a while back (mobile phone sized hotspot) and he thought his
kids weren't using it now since they got their 3G iPads.

Thanks for the feedback though (especially the Solwise stuff) ...
more food for thought. ;-)

Cheers, T i m

Yup, that was my train of though from trying different things (and not
having much luck 'extending' both the USB connected 3G dongle or the
3G aerial.

I've done the extended feeder thing as well and that's a game of
diminishing returns.

Sweet.

I think this might make 5m but that would still be better than *in* an
aluminium Faraday cage. ;-)

I was thinking a compromise might be a remotely powered USB dongle
(I'm not sure if the dongle is getting the full 5V down a 5m extension
lead from a mobile hub) and using one that allowed an external 3G
aerial with short 'pigtail' to place the aerial a bit higher up still?
Might be able to find an omni with a bit better gain than the built in
or a uni / Yagi that I might be able to point towards the local tower?

I have had the same experience but I didn't investigate the cause,
assuming it was the data that was getting 'lost' in the longer cable
(although the same cable worked with printers and stuff.)

If it's just a volt drop then it should be a trivial matter to beef up
the supply pair with thicker wires probably from a separate 5v PSU
rather than the USB socket of the host device.

Cat 5? Usb runs about 5m and then runs out of puff.

While I was waiting for the ADSL to be installed at my current house I
bought a "3" dongle and a router. To get a good enough signal in my
office I had to put the dongle right next to the window on a six foot
USB extension cable. There weren't any power supply issues.

I've also got an external antenna (for a different dongle) which gives a
useful amount of gain when on trains etc. That has a 50cm rf cable on
it. You can also get directional GSM aerials and long rf cables (eg 5m).

Well 5 metres might just be enough to make the crucial difference
otherwise CAT 5 and POE can be used over longer distances..

Just do not, unless your using very high grade cables, take the 2.1 Ghz
signal any further then what you have to..

Yes that might be the idea. The problem is powering the device and
getting a sufficient level of 3G signal into it. Least thats got an
aerial connector so a Yagi or plate with some gain is going to be much
better...

You could of course cobble up a power unit hat powers the USB closer to
the device, its only 5 VDC AFAIR..

Well thats down to the area but height and aerial gain will make the
most of what's possibly available..

The maximum cable length that you can use with USB is limited by
*timing* considerations to about 5 metres. You can provide extra
power all you like, but you can't propagate the signal along the
cable any faster; it's the round trip time that matters.

What you *can* do is to put USB hubs in, with cables between them
that meet the USB timing specifications. An active USB cable is
a single port hub, I believe.

It's not timing on the cable - a piece of wire can never change
the timing. It is the impedence of the cable - some resistance, a
degree of inductance, but quite a lot of capacity - that rounds
off the waveform and adds noise which make it difficult for the
decoder to recover a sensible data stream.

Yup. Isolate the 5V at the far end and feed it directly to the socket
by the dongle, along with the Gnd (but that not isolated) with
something more substantial. As long as the output of said PSU is
floating rwt everything else then it should be fine.

I'm waiting for a replacement SIM for my T-Mob PAYG (ZTE) dongle (I
hadn't used it for over 270 days apparently so lost the number,
package and 10 credit) as I think that was happier on an extension
from the hub than the Voda (Huawei) dongle was.

Note to self ... put note to self in the (wife's) diary to use these
things every 179 days.

Yeah, that sort of thing 'might' be a good idea if I can use it to
'find' the best direction to the nearest mast (then lock it off).

If I go for the temporary 'router *and* 3G dongle up the pole,
possibly with a battery pack' , the Zoom router has signal strength
stats you can watch realtime so that could be quite handy.

Yup. The Zoom router I have now takes 5VDC so 4.8 might be enough for
a fully 'wireless' experiment. I could even try it in the back garden
and see for far I can reach it from down the street. The other problem
here is the local mobile mast is clear line_of_sight a few hundred
yards away so no real test for the 3G side.

You might end up having to butcher a cable, which might give trouble if you
mess with the signal integrity (eg you have to cut into the sheath to get at
the power wires). One option is to add the innards of a small USB hub near
the dongle, where you can get in and butcher the power wires while the fast
USB signals are on a nice stable PCB. Might also prevent the wires flapping
about in the breeze.

N95 with Joikuspot. It will do what you need with no problem. You can pick
up a working N95 8gb on ebay for about 50.

True, however I'm quite good / neat with that sort of thing (BT
trained dontcha know <g>) and have made up all sorts of leads for
people in the past. Nothing like having a good selection of heat
shrink and self amalgamating tape at hand. ;-)

I think I might simply cut the cable off a few cm back from the remote
socket, dress back the sheath / screen, re-join the gnd and data + & -
then tack in my power wires at the same time. Heat shrink up, dress
the screens back over (overlapping) solder tack and possibly epoxy /
heat shrink or self amalgamating.

I have an old Draytek router somewhere that has a USB port on the

Yup, done similar with mine and when the Daughter was up in Scotland,
living with her b/f's family I got her an active 5m cable and they had
the Voda dongle out on a length of plastic conduit. It was pretty
unreliable even when plugged into the PC's so it could just be the
(our) Voda / Huawei E220's?

Handy, cheers.

Possibly swaying of straight phone talk a bit here ..

I would like to have some exposure to Android and probably, because of
my lack of need for a 'Smart Phone' as such but might like a portable
(so ~7" probably) tablet (if my eyes can cope) to use / play with.

I recently got an iPad for Mum (she bought it for herself, it was some
weird swap <g>) and whilst I appreciated them more after playing with
one for a bit and 'the kids' (21 and her b/f) liked playing some of
the free games and some online pictionary type game, I'm not sure we
can justify the cost and I'm pretty sure don't have the need.

However, I think I would find it useful to have a very portable Web
terminal plus some apps (like Opensignalmaps) and with PAYG data
access somehow (ideally built-in).

I've seen cheapo tablets on eBay that look like they could tick most
of those boxes but am aware that many wouldn't come up to the general
'feel' of an iPad?

This might be more in my budget for an iPad clone:
http://www.ebuyer.com/344245-scroll-...ablet-pc-54242

A possible solution to my main needs this could be a solution (except
the 3G bit):
http://www.ebuyer.com/360175-yarvik-...blet-pc-tab360

And this may do most but might be a bit crude?
http://preview.tinyurl.com/cuwkz33

But this whole market seems to be up in the air with prices being cut
across the board. I guess it's like all new technologies ... you just
have to get onboard at some point and know it's going to be obsolete
as soon as you have bought it. ;-(

Cheers, T i m

Your analysis is so wrong that I assume you must be trolling.

Please learn:

1) To analyse transmission lines (the inductance is just as important
as the capacitance, at the frequencies and rise/fall times that matter
here);

2) That the transit time along cables is /not/ zero;

3) The USB specification.

Ah. The router is 'put away' somewhere so I can't check the model

Like my Zoom 4501:

> Then you get

Ok ... and ideally one that would take an external 3G aerial (for more
flexibility / experimentation). Like but hopefully a bit cheaper:
http://www.solwise.co.uk/3g-dongle-lp1917e.html

I think the ZTE K3805-Z dongle will take an external (and available on
eBay unlocked quite cheap) but again not on the Zoom compatibility
list.

The Huawei E160G can be found unlocked for a bit more, is on the
compatibility list and takes an external aerial. ;-)

> and buy a PAYG sim card on Ebay


Well I'm hoping my 'never expiring' Voda Prepay SIM would work in
whatever I get, as should the T-Mob SIM that is apparently on it's way
to me from them after the original one 'expired' (the credit lost and
the number recycled apparently).

I *think* the T-Mob dongle plan I lost was non expiring credit as long
as it was used once every 160 (270) days. Not sure if the new one they
are sending me will be the same.

http://preview.tinyurl.com/c7f7azh

I think the current package comes with Huawei E173 and doesn't appear
on the Zoom compatibility list (but may have an external aerial
socket).

Not sure if it also has unexpiring credit .. I'm guessing it must do
or there wouldn't be much point would there?

The Voda Huawei E220 is on the list but is the one that doesn't seem
to like running over USB extensions (or even via a cheap powered hub).

Too many variables aaarrrggghhh! ;-)

Much better (IMHO) is a router that accepts a SIM card directly, there
is then no (or at least much less) compatibility problem - you don't
have to check if the USB dongle works with the router because there
*isn't* a USB dongle in between the SIM and the router.

Solwise have a couple of routers that accept a SIM directly.

Like this one (the cheapest I think)?
http://www.solwise.co.uk/3g-routers-3g-51r.html

Hmm, whilst I grant you that would remove a layer of complexity I'm
not sure if it would still work with the 4G stuff if I wanted to in
the future? If not the thought was that I could just change the dongle
and be away again with 4G etc? (Although that might all be moot if I
never go to 4G or there is no service in that area etc).

The other thing, once you have found a dongle that works with an
extension etc (as some here have) I'm thinking it would be 'better' to
have the router inside the building / caravan and just the dongle and
USB cable outside.

A mate (who runs a PC shop) has ordered a TP-Link 3G (dongle) router
for me and with the thoughts re the shop and providing some access as
/ when the shop BB goes down.

It won't be expensive but is still mains powered but unlike my
existing Zoom required 12V DC so could run directly off a Car / car
battery etc. (no voltage regs required).

I'll give that a thought though as as you say, it will eliminate what
does appear to be a layer of complication.

Ah, the only other thing would be if I needed a 'better' 3G aerial,
not sure if that one allows you to use an external (I think the more
expensive one do, even if the router itself was at the mast head).

Cheers and thanks for the feedback,

T i m

Knowing Woody he'd not be for a moment be trolling he is in effect
saying the same as what you are albeit in a different way. The concept
is quite simple theres no need to write a book on the subject;!...

That said we did find that for One application a dongle in a plastic
hermetically sealed box did work over around 8 metres and it sufficed
for what was required. We did try two different dongles but one was
slightly better than the other and please don't ask why as I'm not going
the climb up there to find out!.

We did experiment with a separate power source and this did make a
slight improvement to thruput but didn't examine quite why. I expect the
volts at the dongle were sagging a bit..

The other one used a router/modem/seperate aerial and that ran POE over
CAT 5 and did work very well and is in use not as a viable alternative
to running a BT line to the premises which are way out in the sticks..

As BT wanted some 28,000 sheets to provide a line we did have a good
budget for this one but it was done for a couple of hundred quid plus
rigger and job done...

Does it /need/ to be a tablet? £100 for this, er, very portable 4" Web
terminal with 3G on PAYG and it gets a decent review:

Whatever you do, read a few reviews on the device before you buy. Work
bought us a load of no-name 7" 'E-Tabs' and they're just abysmal. Wifi drops
all the time, most of the stuff in the app store won't install, poor battery
life, 2.5mm headphone socket, no Flash support even though it's listed on
the box, etc. Once you've selected a prospective device, another good idea
would be to read through a forum where owners of the device ask questions
and discuss it. That will give you a good idea of what owning one will be
like, and with any luck the diversity of opinions should overcome any bias.

Yep!

Oh I have ... and that's why I've not bought anything as yet! ;-(

Yeah. Mates stepson bought his Mum a Tablet of some sort or last Xmas
(when he was going to get her a laptop in the sales) and he said as
much. She's now got a laptop.

Nice (not). Hers wouldn't seem to hold any settings and the battery
now only lasts 20 mins.

And then leave me in the current position with no Tablet. ;-)

I think I know what I need it to be able to do and what I would like
it to be able to do and few I have seen tick *all* the boxes.

So, I've been playing with Mums iPad on an off for a couple of weeks
and if that is supposed to be 'the dogs' when it come to the format
I'd have to say I probably don't want one (at all). OK, it was very
easy / nice / fun to video their dog and I playing in the garden ..
and being able to play it back on the same hardware and share it with
the family there and then but how often would I want to do that sort
of thing? If *I* did, my Fuji stills camera takes video and I'd have
no issues putting it on my PC or laptop.

For someone that only want's an appliance and is happy to do just
those things it can do (and some of them it does well) or if it really
is easier for you to use than say a Netbook or Laptop with a real
desktop OS then great.

For Mum, at the moment it only seems to be really good for brushing up
her Canasta skills and she seems to have 'mastered' the iPad UI 100%
for that. The rest, like responding to IM / Skype or a few emails
seems, for the moment anyway appears too much too soon for this
particular 82 year old (even though she was pretty good on MSN
Messenger on XP ... I even gave her Ubuntu set up nearly identically
and that booted in a fraction of the time but after a couple of weeks
she actually asked me if she could 'go back to what she had before'...
;-(

No, I think I'd just like 11" MacbookAir (for the battery life)
running W7 and supporting 3G and I'd be sorted. That or just a very
big phone with a Flash supporting browser.

Cheers, T i m

p.p. I 'nearly' got what I wanted from the Palm T|X (ignoring the
mobile BB again) but it's just a bit too small and limiting to be a
real tool.
