I need some information about the router. I want to test the Broadband Device for the frequency range, Bandwidth and control the Bandwidth also so I need to take the control of Broadband Device is an option for the above questions please let me know. thanks for the contributions.
I think your question is not certainly clear that you can use your hotspot tethering service but still, the ISP will be the one who is providing you the broadband facility, so please edit your question and provide more information.

Hopefully I get answer to this question, not sure if this is the correct forum here.
I want to know do laptops (for example, dell, hp etc.) have ONLY ONE NIC card? If so, then how using this card are we able to connect to LAN cable, we are able to connect to WI-FI.
When I see the network adapters, there are many? So what is the relationship between NIC and these adapters?
Can anyone please help me understand this?
There is a NIC for each type (Cable, WiFi and Blutooth ...).
For example: In a PC, which normally comes with one NIC for cable only, you can buy a Wifi NIC to make it connect to WiFi networks.
I'm planning to develop an iphone app and I need to know if it's possible to check if the iphone has any carrier signal or if it's as "no service".
I've talked with some developers and some keep telling me that it's possible while others say that it is not possible...
Anyone can help me with that?
You could look into the way MKNetworkKit handles reachability to domains. Haven't looked in depth, but I think it can tell the difference between wifi, cell network, and no service. That should give you everything you need.

You can use:
int wl = CTGetSignalStrength();
Google maps, ip location etc. working good.
But none of the services are locating a computer exactly where it is on a map.
Anyone know any api which can locate a computer on a map without user inputs.
I am tired of ip location, it is not at all exact and my client is not happy. :(
Thanks

What you're trying to do is not possible without specialized hardware. Google maps on cell phones without GPS uses cell tower station information. Most other phones use actual GPS receivers. With neither of those, the only way for your network-attached computer to tell where it is is by looking at who owns its IP address, which is what the IP location stuff does. Unfortunately, that database has pretty low geographical resolution. If you really want accurate and precise location information, you have to have a GPS receiver.
This cant be done unless you have some GPS device connected to the computer. But I guess it is forbidden in the licence to use real time tracking in Google Maps, but I might be wrong.
There's one more way, but I don't know how practical it is: visible wifi networks. If your PC has wifi hardware then you can often correlate the list of networks that you can see to an approximate location based on databases of networks and position. This is how e.g. iPod touches can locate themselves, and iPhones when there's poor GPS reception in built-up areas.
But even if your end-user has wifi hardware and you can somehow read the network list from it then I'm not sure if there are public datasets for this though.
The W3C Geolocation API allows websites to request the user's best available location from the browser. In some cases this will use IP geolocation which you've already seen to be inaccurate, but it can sometimes do better.
The API is agnostic to the device and the method used to obtain location; on an iPhone, the Geolocation API may use cell tower triangulation, available WiFi network lookup or GPS satellite geolocation, or some combination. On Firefox or Chrome on the laptop, Google uses WiFi networks and IP address to give a location which is often much, much better than IP geolocation alone.
If you had a GPS attached to your computer, it's possible that your browser could take advantage of that too -- it's expected that future versions of Internet Explorer will support the W3C Geolocation API using the Windows 7 Location Platform, which can accept location from an attached GPS or manual entry or some other plugin.
Well, I tried to ask this question as a comment on this question, but I thought that maybe no one will notice it, so I decided to ask it as a separate one.
The question is about how to do real-time GPS tracking system things; if we have the following scenario:
Rather than connecting a GPS receiver to a PC, the user will have a mobile device with an integrated GPS receiver.
Location data will be sent over mobile network using GPRS data connection to a server side.
The data will be processed and a KML path file will be created and updated on time intervals and used to track the user using Google Earth.
The question is: what is the best method to accomplish this scenario for the server side; is it a web service, a web application, a windows service, a windows application or what exactly? Taking into account that the system will serve a number of users simultaneously, and that more users may use the system in the future(scalability issues).
Thank you in advance and I highly appreciate any help :)
What kind of device are you using exactly, something like this or something more sophisticated / configurable? If we assume that the device sends its data over TCP, I would consider the following approach with separate input/output processes:
Input: a process listening specific TCP port and storing incoming coordinates to database with a device id. Preferably, your listening loop must be able to handle simultaneous connections without them blocking each other.
Output: web application reading coordinates from database for a given device id and displaying them through the Google Earth API.
Use whatever programming language(s) you are familiar with.
For me there is a technical limitation/risk here -> the mobile device, and its connectivity.
1) What are your requirements? Do you need to support various mobile devices or will you focus on only one platform ?
2) More importantly, you have to understand that GPRS data connections differ from a PC connected to the Internet. There are various connection restrictions imposed by different mobile operators.
If I was to design such a system in order to minimise those risks I would go with a web server running on port 80 which the mobile devices would upload their Long/Lat through POST (or even GET to simplify things).
EDIT: Regarding scalability, it would be very easy to scale things up in the future using tried&tested load-balancing techniques.
EDIT2: Whichever technology you decide to use, i would HIGHLY recommend that the first thing you do is to mock up a prototype. Those connection restrictions could be show-stoppers. Ideally you need to explore them before you have made any serious investment.
I tried GNUBOX which use bluetooth to connect to my computer then to the internet. It's very painful to set up (under windows more than under linux, but it's still painful, it works 1 time on 3).
I own a Nokia 6630 so there is no WLAN support. Is there any emulator? I'd need to know something like max width, max height etc... usability in general, any hint?
This may sound silly but you could consider getting a mobile tariff with unlimited data. In most European countries these are now available and are not too expensive.
I don't believe you would get a solid experience from any emulator.
Don't know if you're only limiting to the 6630 or not...if not, Opera Mini has a free simulator.
If you find yourself needing to do more testing on multiple devices, there's always Device Anywhere...but it definitely does not meet your requirement for free.
Can you use a data cable and IP pass through?
Since the 6630 is a Symbian phone, you should be able to use GNUbox to handle the connection. See http://xan.dnsalias.org/gnubox/
Keynote's MITE just launched a free version for content testing; it includes the 6630 along with more than 1600 other profiles and 11,000 user agent strings. You can access via LAN get the protocol details.
