How To: Use your 3G Cellphone for Broadband Internet Access
for everyone
This may be a little outdated to inform you but I think it still is a good share. These instructions will allow you to use your 3G or HSDPA phone to be used as a modem to your PC and connect to the internet with broadband speed! I will be using the Nokia N70 as an example unit with Smart as the network provider, but the steps can be applicable to any 3G-enabled phone and other providers.
Things to accomplish first before connecting:
1. Make sure you have the Access points downloaded to your phone (i.e. Smart Internet, Smart GPRS, Smart MMS, etc.)
2. Have your phone suite installed in your PC
3. Once installed, make sure your cellphone drivers are also present when you plug it in to the USB. It should appear as a "USB Modem" in your device manager.
4. Of course, make sure that you have 3G signal in your location, or else you will only be connecting on GRPS speed, which is worse than a dialup!
Connecting to the internet:
1. You may try to use the Nokia PC Suite to connect online using 3G. If you would setup the network connection in the PC Suite, there's an option to choose your service provider. Globe Philippines and Smart Philippines should be there.
2. After choosing your appropriate network provider, try to connect. If you are able to connect and surf, you should be good to go.
3. If it failed to connect, try the next step.
4. Upon your attempt to connect to the internet using the PC Suite, a dialup connectoid is automatically created when you check the Network and Sharing Center in the Control Panel (or Start > Connect to) for Vista; Network Connections for XP.
5. Before proceeding, go back to the device manager and open the properties of the Nokia USB modem.
6. Click the Advanced tab, and here you will see a box for Extra Initialization Command to which you can enter a command string. Input this on the box exactly as it appears: +CGDCONT=1,"IP","internet"
7. Click OK then close the rest of the windows.
8. This time try connecting using that dialup connectoid in Connect To. The dialup number should be set to *99# and that username and password fields are blank.
9. Once connected, you will see a balloon message on the system tray saying that you are connected. 480+ Kbps of connection baby! Enjoy surfing!
Tip: When using Globe, first send the message TIMER to 1111 to start your 5 pesos per 15 minute charge, or else you will be charged 15c per kilobyte. That's gonna hurt. For Smart no further configuration needed, just follow the instructions above.

What Is WiFi?
What's in a name?
You may be wondering why people refer to WiFi as 802.11 networking. The 802.11 designation comes from the IEEE. The IEEE sets standards for a range of technological protocols, and it uses a numbering system to classify these standards.
A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here's what happens:
1. A computer's wireless adapter translates data into a radio signal and transmits it using an antenna.
2. A wireless router receives the signal and decodes it. The router sends the information to the Internet using a physical, wired Ethernet connection.
The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter.
The radios used for WiFi communication are very similar to the radios used for walkie-talkies, cell phones and other devices. They can transmit and receive radio waves, and they can convert 1s and 0s into radio waves and convert the radio waves back into 1s and 0s. But WiFi radios have a few notable differences from other radios:
* They transmit at frequencies of 2.4 GHz or 5 GHz. This frequency is considerably higher than the frequencies used for cell phones, walkie-talkies and televisions. The higher frequency allows the signal to carry more data.
* They use 802.11 networking standards, which come in several flavors:
o 802.11a transmits at 5 GHz and can move up to 54 megabits of data per second. It also uses orthogonal frequency-division multiplexing (OFDM), a more efficient coding technique that splits that radio signal into several sub-signals before they reach a receiver. This greatly reduces interference.
o 802.11b is the slowest and least expensive standard. For a while, its cost made it popular, but now it's becoming less common as faster standards become less expensive. 802.11b transmits in the 2.4 GHz frequency band of the radio spectrum. It can handle up to 11 megabits of data per second, and it uses complementary code keying (CCK) modulation to improve speeds.
o 802.11g transmits at 2.4 GHz like 802.11b, but it's a lot faster -- it can handle up to 54 megabits of data per second. 802.11g is faster because it uses the same OFDM coding as 802.11a.
o 802.11n is the newest standard that is widely available. This standard significantly improves speed and range. For instance, although 802.11g theoretically moves 54 megabits of data per second, it only achieves real-world speeds of about 24 megabits of data per second because of network congestion. 802.11n, however, reportedly can achieve speeds as high as 140 megabits per second. The standard is currently in draft form -- the Institute of Electrical and Electronics Engineers (IEEE) plans to formally ratify 802.11n by the end of 2009.
* Other 802.11 standards focus on specific applications of wireless networks, like wide area networks (WANs) inside vehicles or technology that lets you move from one wireless network to another seamlessly.
* WiFi radios can transmit on any of three frequency bands. Or, they can "frequency hop" rapidly between the different bands. Frequency hopping helps reduce interference and lets multiple devices use the same wireless connection simultaneously.

Process Explorer v11.33
Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded.
The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.
The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.
