FAQ

• What is GPRS?

GPRS - a technology Packet Radio Service (General Packet Radio Service) networks and GSM. The main feature of GPRS is that the information (host / transmitted) is divided into small data packets and then transmitted simultaneously on several channels. Due to this the maximum possible speed access through GPRS technology is 170 kbit / sec. This voice channel is busy only during data transmission, but not always, as with other forms of network access.

• What do I need to use GPRS?

To do this you need to activate the GPRS service from the operator. Naturally, you need to buy a phone that supports GPRS. Here, in principle, and all. Purchase additional accessories depends on what devices you use GPRS-phone. Maybe you do not have to buy anything extra and you have enough IrDA port on phones and laptops. Sometimes with the phone cable is included for connection to a PC (for example, the Siemens ME45/S45). Otherwise, you will have to buy it separately.

• Can I use GPRS via Bluetooth?

Yes, of course. If your phone is equipped with GPRS support and is equipped with Bluetooth, you have the opportunity to use it as an external modem with any device with Bluetooth-module. For example, if we are talking about the laptop, then we need to buy a Bluetooth PC Card and enjoy working with the Internet without wires.

• With what devices can access the Internet, using a connection via GPRS?

There are no limits at all. Absolutely from any device, from an old Palm’s finishing with a desktop computer. The fact that the device itself should not have support for GPRS.

To work through the GPRS connection you need to create a dial-up. If it comes to PDA, you must create an external modem working via IrDA, since all the work needed to produce the data modem built into your phone.

• Can I use a GPRS-modem on a desktop PC?

Yes, it is possible. To do this you need to create a new modem using a special driver GPRS-modem. Usually, the necessary software is on the disk that came with your phone. In case this is not a disc, you can find the necessary software on the Internet.

After this it is necessary to make the modem setup and ready!

• What is the maximum speed of data transmission via GPRS connection?

In the long run rate of $ 170 Kbit / sec. currently, this rate is 40-45 kbit / sec. This is due to the fact that the majority produced is GPRS-phones have 3 timeslots for receiving and 1 timeslot for data transmission.

How to declare operators that they would increase the capacity of their networks immediately after the phones will appear with a large number of timeslots. I do not mean that these phones will do (they already have), but about how, when their price becomes available a large number of users.

• What is the average speed of data transmission via GPRS connection?

Talking about the average speed for GPRS because the information is incorrect or prelates or not. That is, the speed from 0 to 40-45 kbit / sec. But the speed of packet transmission depends on the workload of the network at any given moment. If you are in an old, congested cell, the rate will be minimal. And if you're in the new cell, moreover, absolutely not loaded - speed is always maximum.

• What cell phones Motorola technology support GPRS?

The world's first commercial mobile phone, which was to support the technology GPRS, a camera Motorola Time port P7389i. In 2000 it was discontinued and he was replaced by a more advanced apparatus MOTOROLA Time port 260. In late summer of 2001, the company MOTOROLA has released the world's first device of low price category, which was to support the technology GPRS - Phone Motorola Talk about 192. Currently in the line of devices from Motorola also have new GPRS devices - Motorola V.66/V.60/V.70, Motorola Time port 280 and the Motorola Accompli 008.

Since early 2002, the entire line of mobile phones Motorola GSM standard will support GPRS, as the main function.

• Can I use GPRS for direct connect phone and a corporate server?

Connection standard GPRS connects the phone with a company that provides broadband access to the Internet, much the same way as you connect to the Internet-service provider of a landline. Ability to connect to a corporate server depends on many factors. Perhaps set up a special connection through ISP and succeed. For more information you can contact a company representative, providing access to the Internet.

• Can I use the phone that supports GPRS, abroad?

A telephone conversation requires only the availability of the GSM network and will be possible where agreements for roaming. Data on the GPRS standard will depend on the content of roaming agreements that your company operator has concluded with other operators. More information about this please contacts the representative of your company operator.

• Can I work with a phone that supports GPRS, in Microsoft Windows 2000?

This is possible through a cable, included with the system (RS-232 cable for Motorola Time port 260 and USB-cable for Motorola Time port 280, which are supplied), using the additional software included with the system that supports data transfer via cable and / or infrared.

• How do I know what speed will ensure that the GPRS?

This will be determined by the number of time slots supports your GPRS phone to transfer data (such as Motorola Time port 260, a Motorola Time port 280 and V.66/V.60/V.70 - 4 time-slots, i.e., at least 38.4 kbps) and also to some encoding scheme uses your mobile operator at this time.

I've been using Motorola phones enabled for GPRS. After the change of the company-operator GPRS is not working. Why?

Each operating company makes equipment for their requirements. Phone GPRS, sell you the first operating company, has programmed its network WAP and GPRS settings. Perhaps you can change these settings when you connect your phone to a PC standard GPRS, using the software GPRS Wixard (or GPRS Manager), bundled. By clicking on the button (Advanced) in the wizard GPRS (GPRS Data Wizard), you will get an opportunity to change some settings. More information about changing settings when you switch to another provider to ask the representative of the new operating company.

Can I use my cell phone Motorola GPRS as a modem for computers running the operating system other than Microsoft Windows?

Currently, these operating systems are not supported.

• How to use GPRS on a desktop computer or laptop?

Run the CD-ROM with software GPRS Wizard (or GPRS Manager), included in the set, go to the Master GPRS and correctly enter: APN (Access Point Name, ARM), name the connection (Connection Name) and if necessary, IP - address (usually the address is dynamic, that is changing with each registration). Activate the connection by double-clicking on the mouse icon and enter your username and password (which also gives the company-operator).

• GPRS - a real connection to dial-up?

No, the call data does not actually performed. Phone is automatically registered in the GPRS network and if necessary, loads the necessary information. You pay only for the amount of information that you download (that is, the number of transmitted packets). At the same time you force roaming on the GSM network and you have an opportunity to respond to challenges (all Motorola phones currently have a Class B (Class B), which supports this feature).

• Can I talk on a cellular phone during a session of GPRS?

Yes, it is possible. The fact that during the conversation, GPRS-access, you occupy a voice channel is not constant, is the main advantage of this technology. Channel is busy only during the transmission / reception of data. If you receive a call, the session will be interrupted and will resume automatically after the end of the conversation.

It should be noted also that there are three types of GPRS-modems - A, B, C.

C-Class - this usually is GPRS-modems on them is not supposed to talk, they are created only for data transmission. Most often it is PC-GPRS card for notebooks.

In-class - vehicles capable of operating as regular phones, as well as GPRS-modem. Currently, all phones are sold to the A-class. That is, they you have the opportunity or bring / take data, or to speak in turn.

A-class - it sets a new generation, they may simultaneously transmit / receive data and talking. While the market of such devices on sale there, at least officially in Russia, they are not sold.

• Can I send and receive SMS during a session of GPRS?

Yes, it is possible. This situation is like and if possible to receive calls during the session. Once the image is a pause in the sending / receiving data, you will receive SMS-message. In this connection is not interrupted, but only stopped for a few seconds.

• What are the advantages compared with GPRS Dial-Up?

The advantage is that during the session GPRS you only pay for received / transmitted information. But when Dial-Up connection you pay for the session. For example, if you are using Internet-pagers, then you pay for unprofitable time spent in the network. Much more effective in this situation to pay for traffic that will be a few kilobytes.

• Can break off GPRS-connection?

No. At least, based on experience, it is safe to say. If you are not moved during a session of the different cells, then the connection will be absolutely stable. Rather, the battery sits in the phone, what is broken link.

• Can I use GPRS, for example, moving a car?

Yes, it is possible. Operator does not warrant such a possibility, but as experience has shown, it is quite real.

It is worth considering that may cause problems when moving between base stations, as it may be that you will come to an overloaded cell. Resulting in a refusal GPRS-session. But it happens rarely. Even if you move the center of Moscow, where the number of base stations is very large, and congestion is obvious, the connection was stable.

• How do I pay services GPRS?

Currently in commercial use GPRS service launched only company . So the issue of payment for GPRS can arise only for the subscribers of that operator.

following options tariffing: paid all received / transmitted by MB. One megabyte is charged at $ 0.30 all taxes included.

You will receive regular account, which will see the amount of $ that you spend using the GPRS-connection. It is counted to voice traffic, and you can pay for this expense, as usual, in any convenient place for you. You do not have to pay for GPRS separately.

• On what conditions the network provides GPRS?

Currently, GPRS services are provided on a secondary basis. This means that the operator is a priority for voice traffic. In the event of a situation in which Sota will be overloaded with users, the equipment will automatically limit the ability of GPRS-access. As soon as the number of users in a specific cell decline, again, automatic equipment configured to provide GPRS services in full. This is done in order to not restrict the provision of voice traffic to subscribers.

• Can I use WAP via GPRS?

Yes, it is possible. All sold now, GPRS-phones allow this. It is worth considering that the operator able to use WAP over GPRS is charged separately. You pay $ 3 and are using WAP a month, without paying the amount of transmitted / received information. This form of payment is convenient to subscribers who do not plan to use GPRS for other purposes.

• Are there plans to increase connection speeds via GPRS operators?

Yes, it is planned. As soon as the phones, capable of operating at higher speeds. Operators will be ready for this. The main problem lies in the fact that the increase in the number of timeslots will lead to greater re-Transshipment of base stations. It will be necessary to increase the capacity of the network.

• What determines the speed of connection via GPRS?

Speed of data transmission in GPRS-network depends on several important factors. The first and perhaps most importantly, this network overhead. Or a particular cell at a given moment. Also, the rate may affect the old equipment and software installed on the base station. Second, the number of timeslots allocated for the work of GPRS.

• How long the phone can work with GPRS on the same recharge the battery?

It depends on the capacity of the battery in your phone. It is worth considering that during the session GPRS energy is consumed is not constant and with varying capacity. This is due to the fact that the energy consumption occurs only during the transmit / receive data. And, is of great importance to how much information is taken / passed. If we are talking about Internet-pager, the phone will work for very long, but if you regularly download large files, the battery is discharged quickly.

On average, the time may be determined by the number of reported hours of talk time.

• I heard that the radiation when working with GPRS is harmful to health is it?

Radiation during GPRS session is identical to the radiation during a normal conversation. The only exception is the power of this radiation. In case the phone for data transfer uses three timeslots, and on all of them are data transmission, respectively, the power of radiation in this case is three times more than in normal mode. Therefore, we strongly recommend you keep the phone during a GPRS-session as far as possible from the head and other vital organs. On the other hand, while no one has documentary evidence to prove that radiation from mobile phones can lead to disease.
