12volt wireless networking

[ecoed]

which wireless 12volt router will give me the best distance coverage? I only have 12volt electricity powered by 1 wind turbine and 2 solar panels . Currently using a netgear 'next wireless-n'. DG834N and the current range is about 75meters in a direct line.

difficult question .... my trusty (rusty(?) linksys is 12 V
but realy there isn't a definitive answer.. some come with hi-gain ariels and 802.11n should be about as good as it gets .... but define coverage ... I've never yet seen a wireless link working anywhere near the advertised 100m
There are so many variables .... fog rain ... thick walls ... thin walls insulated with reflective aluminium .... blah blah blah

and even with "only" 12v you could use an inverter to convert to 240v .... so not realy an answer

Your question, in wireless terms is like asking where the holy grail is.

The wireless router is situated in a child's wooden play house approx 4ft x 4ft this is in the middle of a field with no obstacles oh and its on stilts 4ft high. I can't use an inverter as this consumes electricity- they are not very efficient. I am trying to get a 12 volt wireless network that will cover 11 acres.

Most military installations won't cover that far!!!!!

the 802.11 spec quotes maximum of 100m
in practice ... this is never achieved (20-30m is nearer).

I'd have thiught that the majority of routers would run from and external supply (and generally be 12 v from a power requirement?)

you can get "burners" (high gain )https://www.youtube.com/watch?v=LY8Wi7XRXCA

but in my experience the trade off is they are very directional.

most offices use a series of repeaters ... but unless you can build a hut every 20m ... that's not practical

i had previously used a belkin wireless n router the range was great but the power surply needed was 18 volts. used with an inverter my power only lasted 3 days. there must be a better quality router that will serve my needs...... is there? check out my patch of land. http:// www.mellowcroft.co.uk

based on the scenery .... I'd have thought you'd have a total ban on anything manufactured within the last 60 years!!.
Nice nice nice ...

Realy can't think of anything practical that will give you what you want .... BT and Borough of london use extensive arrays of repeaters to get coverage ... the military tend to go for height or direction .... none of it is practical to we mortals.

75 meters is outstanding - but there are a lot of 75meter patches in 11 acres.

Whatever else it's used for. wireless is designed for single or cell working. but the assumption is that there is always another unit nearby
In an office you pay �100s for an analyzer to site repeaters in a pattern designed to create the least number of echos.

the alternative is to use burners ... but high gain aerials cost a fortune.

Wired Ethernet is only good for 100m and then you need a repeater.

you could try individual solar panels to power an array (the car battery charger may just maintain 12V at a reasonable current ..... the downside there is location .... solar power .... in Wales?????
(you could try hydrogen cells ... or a waterwheel)


I'd have to suggest forgetting that sort of coverage ....
hang a couple of wind chimes and a dream catcher ... and call it a retreat.

Another alternative would be to use the 3g mobile network .... but bandwidth tariffs are unreal at the moment (but that has to change.

Hi BT Hubb 4 is 13v cut the lead off the adapter make sure you get the right polarity dc dont like the wrong polarity it will work fown to about 6v after that it gets unpredictable if you disconnect the battery before the solar panel you will blow the unit try not to turn it off or it will get slower and slower and have to be reset at by server all facts ive been using these for 4 years good luck
