I have a wristband-device which gathers physical data and I need to upload the collected data on a web server in real time. What circuit will help to achieve this??

For example:

I have a wristband which has it's own deviceID as 1. Suppose, I want to upload the deviceID to a web service on my server such as http://www.foo.com/webservice/gatherData.php?id=1. The web service will take care of the rest. Any idea how can I achieve calling of this URL through TCP/IP protocol stack through some hardware module or circuit?

P.S.: This is my first question here. Help appreciated. Thank you.
 

if you have a local network connection you could connect the device to a microcontroller to connect to the internet thru wired Ethernet or WiFi, e.g.
**broken link removed**
**broken link removed**

if you don't have a local network you could use a TCP/IP enabled modem
 

But suppose I'm cycling on the streets with my wristband on & need to send the data to the server... what should I do then??
 

I guess you know about options for mobile internet access? In addition you should consider connecting to a mobile phone via bluetooth and transporting the data through an app.

I wonder if logging the data with timestamps and transferring it later might be a better solution?

you could use a TCP/IP enabled modem
send UDP datagrams to a server or set up a TCP connection

alternativly send SMS text messages to a m2m service?
 

it depends what is 'real time', i.e. how often you would upload data

if every few minutes could use an SMS message to an m2m service
of if more often UDP datagrames or a permanent TCP connection

do you need to upload in 'real time'? for example, could you sample every second for 10minutes,store data in an FRAM then upload?
 

I presume, the system does all mobile communication through mobile phone app, as allready suggested.

Yes, they do. But I wish to bypass that so my band can communicate directly with the server. Is there a way to do it??

I was hoping if it is possible in real time. Suppose someone wishes to constantly track my location while riding the bicycle using the band, is there any way to do it??

use a modem, set up a TCP connection and send data how often you require.
you may have problems with loosing connection in areas of poor reception
