Cell Phone Advice for totaly blind needed for use in OntarioCanada

Aman,

OK, the 50k or so for vicinity views is so that WF can send to you all of
the data needed to construct a around you view, if you install the maps this
data is on your phone, thus there is no download at all, whether you use
Guide view or Vicinity views.

The only time you download data if you have the map whether for guide or
vicinity views is whereby the rout that you have calculated travels outside
the pre installed map data coverage.

Otherwise you're only paying for licence check at start-up.

The 150 - 300k which you are right about having seen, is for using the map
view, when you use the map itself, which quite a few Mobile Speak clients
seem to do, over the vicinity view, this is when the cost comes in. A full
technicoloured map is downloaded to the handset, which is vectored etc, this
is memory intensive. The good news is that WF does store the map if you use
that option, so it only downloads it once and then updates if necessary.
When using WFA though in the vicinity view, it gives the same data but in
list view, which is plain and colour free, unlike the intensive vector map
in the sighted persons view.

Hope this clears this up, feel free to ask more though if you are unclear.

Thank you very much, Neil and David. That's most helpful. I had kept reading
on the web that WF required 150-300 KB per hour. That can chew through the
tiny amounts of data available to us in this country, at least on most
providers, very quickly. I appreciate the correction and, indeed, have an
E65 and a GPS receiver here the only reason I haven't tested with is that I
had dire visions of my next phone bill having to be delivered by UPS in a
crate.
	One clarification, though, if I may ask it. Neil said The maps that
you can download include all POI data that is available.

	If I may ask, then, what am I downloading in the 5-10 KB for guide
view and the 30-50 KB for the view with POIs? If I already have the POIs and
the map data, what is that data I'm downloading and can it be dispensed
with? The reason I ask is that as it stands, I have to pay around $60 a year
to maintain my GPS access if I were to choose the $5 plan David uses. If I
only had to pay for the fact that WF was checking its licensing, that would
only be 1 kilobyte per session, and thus usable on a pay as you go plan, on
which kilobytes are 3-5 cents each. On a pay as you go plan, you would be
spending $1.50 per hour on the 50 KB view and around 30 cents on the guide
view. Though that isn't much, multiply it by 30 days or even by 60 to get a
service used twice a day and you obviously might as well switch to a monthly
plan. Is the 5-10 KB for guide view the best we can do?
	Thanks again.
	Aman

Aman,

Only 2 - 3 MB per month as follows:

The typical journey uses 5 - 10 kbps per hour of use, this is when only
using the Guide View, which is all I use I should point out, a user wanting
more heavy info like POI's on route etc will use more like 50 or so kb per
hour.

But if you now just do the math. There are 20 50kbps one hour journeys in a
1Mb unit. So that's a lot of use even at the higher end.

But now if you like I only use the guide view, which will get you from where
you are to where you want to go step by step then there is 100 hours at
10kbps per hour... That's a lot of walking.

Yes you can download maps for a given area which is what I just recommended,
however WFA also checks your licence as it loads, each time, although this
is only about .003kb according to my data use.

The maps that you can download include all POI data that is available.

Hi, Neil.
	You say
In any event most typical users only use roughly 2 - 3 megabytes. Which
shouldn't cost to much with most cell providers.

	I'm surprised it's so low. However, do you mean 2-3 megabytes a
month, a day, a trip, or some other measure? Finally, is there any way at
all to eliminate all data usage for WFA? I mean, even if you have, say, a 4
or 8 gig card, would you be able to download all the maps/POIs/whatever
other information it needs for a specific area and not use the network at
all? I have asked this of WF themselves but have not received a response.
	Thanks.
	Aman

Sharon,

WFA can have very little GPRS data use, especially if you install the maps
for the area to which you live and those you travel within and around.

In any event most typical users only use roughly 2 - 3 megabytes. Which
shouldn't cost to much with most cell providers.

Hello,

I am in Peterborough, Ontario Canada.I don't care what provider I am with.
Currently with Bell but on pay as you go.I am wondering about the Sendero
GPS coming out with cell. The wayfinder I don't think is practical where I
live because of the monthly expenses that would be necessary to support GPS.

I am afraid I am not very technical.

Any suggestions appreciated.

If my needs are too specific to suit the list, please feel free to contact
off list.

Thank-you

Sharon
