For years people have wondered “Who could that be?” every time the phone rang, but with the advent of caller ID technology, few people were left curious about the answer to that question. However, as more people purchase and use cell phones, caller identification is becoming increasingly obsolete as the name associated with the cell phone number frequently doesn’t register on the caller ID box. Fortunately, reverse phone lookup services can help you connect the name with the cell phone number, and they’re fairly easy to perform.

The first step is to find a reputable reverse phone lookup site. While there are both free and paid sites out there, you’ll want one that can offer you comprehensive lookup search services, and any companies that can access cell phone directories will have to charge a fee for their services. Once you’ve found the site that you’d like to use, your next step is a simple one – type in the phone number in question.

In just a few seconds, the phone number tracker will return results containing the necessary information that you are looking for. In most cases, you’ll not only get the name associated with the cell phone account, but you’ll also get a physical address too, which may help narrow things down a bit more. Additional information such as email address and company names are sometimes also included in the report you receive.

This simple process ensures that you’ll never stare at an unknown number again and wonder about the caller’s identity. Looking up a cell phone number can give you the peace of mind you deserve when just a number registers on the caller ID. Whether it’s your cousin from Montana you haven’t talked to in years, your sister calling on a new cell phone number, or an annoying prank call, a reverse lookup can quickly give you the answers you need.

You can monitor your computer while you are away from it and it will cost you almost nothing. A smart phone that has either Bluetooth or GPRS and a small application that can be freely downloaded from the Internet is all you need to begin monitoring your PC.

This is a simple project that you can complete in less than 10 minutes. There are many applications available on the Internet that can help you monitor your computer using your mobile phone. The application we are going to describe allows you to control your computer from a mobile phone using Bluetooth. You can also find applications such as RemotePC2 that allow you to control your computerthrough the internet using GPRS on your mobile phone. RemotePC2 can be downloaded from ‘http://www.getjar. com/products/57007RemotePC2′ and it works with any J2ME-enabled mobile phone. We tried using it, but found that the performance was not impressive. Also, we were not able to use it over the Internet because we are behind a proxy server, and this application requires you to have a live IP. There are other Windows Mobile applications available on the Internet that you can use to control your computer using Wi-Fi. We hope to bring you that project in the near future.

The software and hardware requirements for this project are:

A Blue tooth Dongle

This can have a range between 10 to 100 meters, depending on your requirement and budget. A Bluetooth dongle that supports Bluetooth serial ports is preferable. We used an SMC Bluetooth dongle which is easy to configure and has a range of 10 meters. This will cost you around Rs 500. This, of course, is assuming your computer doesn’t already have Bluetooth built-in.

Any smart phone running Series 60 (S60) 1st and 2nd edition.

The application we used here does not yet support S60 3rd edition or phones that run on propriety operating systems, even if they are Java-enabled. We used a Nokia 6630 for this workshop.

Control freak symbian software

This can be downloaded for free from ‘http://mtvoid. com’.. This download contains the programs that you’ll have to install on your Windows computer and also the smart phone. We have used Windows XP for this workshop.Control Freak uses a Winamp plug-in to start the server. Winamp can be downloaded for free from ‘http://www.winamp.com’.

Winamp 2 or 5

Winamp must be installed on the computer before installing Control Freak.

COMPUTER:

Any computer that runs on Windows 2000 or higher and has a free USB port to support the Bluetooth dongle will do. A Bluetooth-enabled laptop will also be fine for this purpose.

The installation is quite simple. Just download Control Freak and save it on your computer. Double click the .exe file and keep clicking next. No configuration is needed. The application will place a ‘controlFreak.sis’ file on your desktop. This file is the client software that needs to be installed on your mobile phone. Install it through Bluetooth or through the software bundled with your phone. After installing it on the phone, a new item titled ‘CtrlFreak’ will appear in the applications menu. When the Control Freak PC application finishes installing, it will launch Winamp and the Winamp-plugin will try to configure itself automatically. If you are using your computer’s default Bluetooth drivers, no manual changes are needed. If you are using a Bluetooth device that requires installed drivers, you should select ‘Installed other’ as the Bluetooth driver. You then need to set the Bluetooth virtual serial port (also called a COM port which the plug-in will use to communicate with the phone application. This process is usually easy, but it varies depending on your Bluetooth software. An important thing to remember is that your computer uses separate COM ports for incoming and outgoing connections. You need to check your Bluetooth software and make sure that you are using the incoming COM port correctly.

Next, open Winamp and type the shortcut combination ‘Ctrl + F’. A window that displays the connection properties of the Bluetooth pops up .Set the Bluetooth driver as ‘installed other’ and choose the COM port you installed using Bluetooth, Select the ‘Startup with Winamp’ check box if you want the server to load every time you open Winamp. Click ‘OK’ to finish.

Now start the ‘CtrlFreak’ application on your mobile, choose ‘Options’ and select connect. The software will ask you to connect to the computer. Here you may have to enter a pass code on both the mobile and the computer to pair the device with your PC. Usually the pass code is ‘0000′. Once your mobile is connected to the computer, the display shows the current song playing in winamp. Choose ‘Options’ and select ‘Computer Desktop control (8)’ from the application menu. The moment you click on ‘Select’ the screen will display the same content that is being shown on the computer

You can access the computer from a distance of 10 to 100 meters depending on the Bluetooth dongle and phone you are using. The bandwidth may be affected if you have too many walls between your computer and the mobile.

You can watch full screen videos or view photographs by controlling your PC with your mobile. You can switch from normal screen mode to horizontal full screen mode, change the speed of the mouse cursor on the PC, or change the image type you receive from automatic to BMP or JPEG. You can also set how your phone disables remote. control when you receive a call. You can add, remove playlists, and even use the screen to show a Winamp-style spectrum analyzer while playing a song

You can also use this application to remotely (temporarily) use your computer while you are away from your desk at the office or to browse the Internet using your computer if you have a compatible mobile phone with a fairly large screen.

BASIC INFORMATION:

Confused about mobile related terms like CDMA,PTT,GSM,SI,EDGE etc.. if so read below

• Global System for Mobile Communications

This is the most popular standard for mobile phones in the world. GSM service is used by over 6 billion people across more than 200 countries. The GSM standard makes international roaming pretty common between mobile phone service providers, enabling all their subscribers to use their cell phones in different parts of the world.

• Code Division Multiple Access (CDMA)

CDMA is a form of multiplexing and a method of multiple access that does not divide up the channel by time, or frequency, but instead encodes data with a special code associated with each channel and uses the constructive interference properties of the special codes which can perform the multiplexing. CDMA also refers to digital cellular telephony systems that use this multiple access scheme. CDMA phones usually do not need a SIM card.

• General Packet Radio Service (GPRS)

GPRS is a mobile data service available to subscribers of GSM mobile phones. GPRS data transfer is mostly charged per kilobyte (KB) of transferred data to and from the cell phone. GPRS is utilized for services such as Internet and MMS. In the future, it is still anticipated that low cost voice over IP will be made available in mobile phones.

• Subscriber Identity Module (SIM)

SIM is a removable smart card that is used in the cell phone and was available in two standard sizes. Initially it was the size of a credit card, while its more popular and widely used mini version has a width of 25 mm.This has been adopted by most cell phone manufacturers. The SIM card securely stores a key code which identifies a mobile phone to its service provider.

• Enhanced Data rates for GSM Evolution (EDGE)

EDGE is an enhancement to the GSM networks which makes use of theTDMA (Time Division Multiple Access) frame structure, logic channel and 200 KHz carrier bandwidth. EDGE is not only capable of providing three times the data capacity of GPRS but also has improved data transmission reliability. EDGE is employed for advanced mobile services that require high data transmission rate such as downloading of audio and video clips, high speed and quality Internet access etc, EDGE is classified as a 2.75G network technology.

• Push-to-Talk (PTT)

PTT also known as Press-to-Transmit, is a method of conversing on half-duplex communication lines by making use of a momentary button to switch from voice reception mode to transmission mode. Some mobile operators offer the PPT service on mobile phones; it allows voice signals to be transmitted from one user to another on the system without the need of an established existing connection.

• 3G- 3^rd Generation Technology

3G (or 3-G) is short for third-generation technology. It is used in the context of mobile phone standards. The services associated with 3G provide the ability to transfer simultaneously both voice data (a telephone call) and non-voice data (such as downloading information, exchanging email, and instant messaging). In marketing 3G services, video telephony has often been used as the killer application for 3G.Worldwide roll-out of 3G networks was delayed in some countries by the enormous costs of additional spectrum licensing fees. In many parts of the world 3G networks do not use the same radio frequencies as 2G, requiring mobile operators to build entirely new networks and license entirely new frequencies; a notable exception is the United States where carriers operate 3G service in the same frequencies as other services. The license fees in some European countries were particularly high, bolstered by initial excitement over 3G’s potential. Other delays were as a result of the expenses related to upgrading equipment for the new systems. Japan and South Korea were relatively quick to adopt 3G, because their governments prioritize technological infrastructure development, and spectrum licensing fees are minimal. Currently 3G compatible phones in are sold in India by Nokia, Sony Ericsson, Samsung etc, but currently no operators are providing their services based on 3G.
