[Loadstone] Cellular sites, mobile masts and towers

For the benefit of everyone...

Mobile networks have several towers strategically placed throughout their 
coverage area.  When you switch your mobile on, it searches for the 
nearest mobile tower and logs on to the mobile network.  This way the 
mobile provider knows where you are and how to route calls to you if 
someone rings you or if you want to place an outgoing call.

These towers can be placed anywhere from 500M to 10KM depending on various 

How densely populated the area is

What the physical terrain is for the area

For the above reasons, towers residing in cities tend to be closer 
together and rural towers tend to be further apart.  Having lived in both 
Canada and now the United Kingdom, I can tell you that the UK tends to 
have way more towers much closer together.

Each tower has a unique identification number assigned to it by the mobile 
provider.  Loadstone can monitor these towers and can tell you what tower 
you are closest to.  Since human beings use words more than long strings 
of numbers we've made it possible to assign textual labels to each tower 

You can configure Loadstone to tell you automatically when you enter and 
leave cell sites (tower region) and even assign a textual label 
automatically based on your current GPS position if you have one.

Using cell sites for positioning is definitely better than nothing if you 
do not have a GPS receiver or if you're out and about and your GPS 
receiver's battery dies even though the accuracy is quite pour.

Let's say you are on a train and the conductor helpfully announced the 
stops (a rare occurrence).  You could get to your stop and immediately 
label the current cell site (tower) with a meaningful textual description. 
This now means that on other days when you aren't so lucky to have the 
stop announced that you could find it yourself.  This also can work for 
bus stops in densely populated areas.

Does that description help at all?

Hi Monty,

Can you explain a little more about how the cell feature works and what you
can do with it?

Many thanks,

I'm glad the instructions worked for you.

Two answer your question, you are able to examine your database by going
into Exploration mode.  You can enter exploration mode by either pressing
the 0 key or via the Function menu.  From there you can move around the
points and see how they relate to each other in terms of direction and

The other useful feature Loadstone has whether you have a GPS receiver or
not is the Cell monitoring.  It obviously isn't anywhere near as accurate
as points saved when using a GPS but it can be helpful on buses or
trains to know at least what neighbourhood you are in!

Now you just need to find a decent GPS receiver for a good price.  Perhaps
others have suggestions!

Best regards,
