question about GPS cell tower.How Accuracy it is ?

i am developing gps location with Cell tower.

i use opencellid (http://www.opencellid.org)


but it seems the accuracy is very low. for example . i lauch my test app in my office. the opencellid server feed back a xml file . the longitude and latitude is 2.6 kilometres far away. is it a normal accuracy?


here is my code:

String url = http://www.opencellid.org/cell/get?key=xxxxx&mcc=xxx&mnc=xxx&cellid=xxx&lac=xx;

                httpConn = (HttpConnection) Connector.open(url, Connector.READ_WRITE,

inputstream = httpConn.openDataInputStream();

....read data use inputstream.


is it right?

seems very easy.


the data server feed back a xml file like this:

<rsp stat="ok">
<cell range="50000" lac="xxxxxxxxx" lat="xxxxxxx.xxxxxxxxxxx" nbSamples="20" lon="xxxxxxxxxx.xxxxxxxxxxxx" cellId="" mcc="xxxxxxxx" mnc="xxxxxxx"/>



does the range=50000 means that the precision is 50 kilometers?if so , it is too big a pricision number?


in fact. all i need is a precise gps location for both gps and non-gps device. the gps satellite is very precise. but can only be used outdoors.


any one have some advise for me?

Re: question about GPS cell tower.How Accuracy it is ?

well, the website says:

There is some accuracy issue, as the cell can cover from several hundreds of meters to several kilometers
