Using a mobile phone as a modem to access the World Wide Web

What features and functionality has to understand the purchase to take full benefit of accessing the World Wide Web through a mobile phone? Although this may appear complicated and involved ... information minor goes a long way to "keep it simple."

For the sake of dialogue .... Say you have a mobile phone specifications following:

Network ...

2G Network GSM 900/1800/1900-

3G Network UMTS 2100

Data ...

GPRS-Clause of ten (four + One / three + two slots) ,32-48 Kbps

3G-384 Kbps

You have configured the software program provided with the mobile software on your laptop .... and after connecting the mobile phone to laptop using the USB connection can login World-Wide-Web. The setup used in the application software is "Type = GPRS contact." The rate of connection (downlink) is about 375 Kbps when control over a device to obtain freely in the World-Wide-Web .... and the phone as a modem speed of 460.8 Kbps shown all the time (in the network connection). Since the rate is much lower at 384 Kbps (3G speed gives the specifications of the phone), it is likely that the use of 3G. Because GPRS is also supported, where the protection of 3G is not can get, most likely ready to exchange GSM / GPRS.

Your service provider says helping EDGE, GPRS, 3G and HSDPA / HSUPA.

Here are some questions that you may be able to apply .....

* What are the greatest theoretical speeds of EDGE, GPRS, 3G?

* What is 3G really mean here?

* What are the underlying technologies used by my phone?

* What best strategy is to connect the phone to the laptop Bluetooth or USB?

* Your mobile phone Bluetooth specification says v1.two and USB 2. and you've heard USB2. (480 Mbps) is faster than Blootooth v1.2 (one Mbps). Is this correct? Will it make any difference, because of its connection phone to the World Wide Web is 375 Kbps?

Here are some comments so I can operate through such a stage .... and related queries to:

For confidence, the speed with USB 2. should be significantly higher than through Bluetooth (any course).

3G is a technology innovation network which should provide some extended data solutions, in addition to the normal GSM features. Still, I would support the consideration of the service companies, because you must have actual specifications you requested.

Theoretical speeds up to ten individual cases EDGE GPRS. But once again, taking into account these depend on network configuration you have to check with your service provider.

Due to the fact the speed is less than 1 Mb / s, frankly, no problem if you use Bluetooth or USB - speeds above reason. I use what is most trouble-free for you.

In any case, the edge / HSDPA speeds however, are much slower than Bluetooth or USB, so no bottleneck at your own pace. As well as very long as the battery is about to operate, you can connect however you choose a.

3G HSUPA is 3 rd generation High-Speed ​​Uplink Packet entry - a 3G mobile telephony protocol, which has a higher data transfer speed and capacity of up three.6 Mbps in the downlink and up to 1 Mbps in the uplink, under ideal circumstances.

3G HSDPA 3.6 3G network is a great rhythm Downlink Packet Entry cellular telephony protocol, which offers better data transfer speeds and capacity of up 3.Six Mbps link downstream and up to 348Kbps on the uplink, under ideal problems.

3G - 3 º rate was high Downlink Packet Access - provides a faster transfer rate customer information and variables to web accessibility and e-mail of up one.eight cellphones.capacity Mbps in the downlink and up to 348Kbps in uplink

EDGE (Enhanced Reporting charges for GSM Evolution) or EGPRS provides data transfer rates significantly faster than GPRS or HSCSD. EDGE increases the rate of each time interval at only 48 kbps and allows the use of up to eight time slots, offering a data transfer rate optimal of 384 kbps.

HSCSD (major speed circuit switched to Information) allows information to be transferred much faster than the typical GSM (circuit switched to Information) program, using a variety of channels. The optimum amount of time intervals that can be used is four, providing optimal load transfer of information of 57.6 Kbps (or 38.4 kbps in GSM 900). HSCSD is more expensive to use GPRS, simply because the 4 slots are used at the same time - which does not transmit information in packets. Mainly because of this, HSCSD is not as well known as GPRS and EDGE is replaced.

GPRS - General Packet Radio Company is a mobile can get information to customers with GSM mobile phones. With a GPRS connection, the phone cell is "usually" and can transfer data quickly, and greater speed, typically 32 to 48 kbps. An additional benefit is that information can be transferred to the identical time as the creation of a voice contact.

I would advocate the use of USB as it is faster then Bluetooth. You will not have a bottleneck created by the Tablet PC link to the website of bluetooth.

As for the underlying technologies ...

The phone is connected to a 3G network that will work with W-CDMA (wideband code division multiple entries) W-CDMA is the protocol higher transmission speed and technique used in UMTS, a third was seen-a 2G GSM insurance networks worldwide.

When your mobile phone in 2G GSM uses a form of TDMA multiple access (time division).

A again .... the main message is: Whenever possible, simplify
