P800/P802 White Paper, January 2003 91 Remote Synchronisation Remote synchronisation takes place over the air using HTTP and is the ideal way to keep the P800 up to date. Using GPRS, the P800 can be continuously connected to the remote synchronisation server. Synchronisation services will be offered by mobile operators, third-party service providers and as added capability to corporate PIM applications. Corporate PIM applications such as Microsoft ® Exchange and Lotus® Notes® can be supplemented with SyncML capability. PC Suite for P800 Local Synchronisation The P800 is supplied with PC software for local synchronisation. It may be loaded from the PC Suite for P800 CD-ROM. Bluetooth, Infrared or Cable The P800 always synchronizes using SyncML, regardless of connection type. It connects via Bluetooth wireless technology, infrared or cable. The cable is connected either directly to the phone or to the desktop charger.
P800/P802 White Paper, January 2003 92 Automatic synchronization Synchronisation can be configured to start automatically, given that a suitable synchronization program must be running on the other device: • When the USB cable is plugged in to the P800. • When the P800 is placed in to the desk stand, and the desk stand is connected to the other device. • When Bluetooth is activated on both devices and they come into operating range • When infrared is activated on both devices and the infrared sensors are aligned. Intelligent process A synchronization engine performs the task of synchronizing. For local synchronization, the synchronization engine is an application that runs on the desktop computer. The synchronization engine compares, updates and resolves conflicts to ensure that the information in the phone is the same as that in the computer. Compatibility The supplied PC software enables synchronisation with the following applications: • Lotus ® Organizer® 5 & 6 • Lotus® Notes® 4.6, 5.0 • Microsoft® Outlook® 98, 2000, 2002 The PC requirements are as follows: • Microsoft ® Windows® 2000, Me, XP • Minimum recommended hardware configuration for the version of Windows in use. • 30Mb free space on hard disk File Transfer Utility A utility is provided which enables files to be transferred to and from a P800 connected to a PC. It makes the P800 appear as a device in Windows Explorer. The Internal Storage and Memory Stick appear as two drives connected to the device: View of the P800 internal and Memory Stick storage in Windows Explorer
P800/P802 White Paper, January 2003 93 Typical uses for this include: • Archiving pictures taken on the P800 to PC storage • Moving images to the P800 to use in personalisation, MMS messages etc. • Moving sound clips to the P800 for personalisation. • Store work documents (Word, Excel etc) on the P800 to read whilst on the move. Backup and Restore Backup is initiated from the connected PC. Note that the Syncstation desk stand must be used for backup and not infrared or Bluetooth wireless technology. Files in the user data area (which includes loaded third party applications) are backed up to PC storage. The restore utility takes stored data from the PC and places it back on to the P800. Language Change Utility The P800 has a larger, richer UI compared to an ordinary mobile phone. Applications often have help information also. Consequently, it is impractical to store many languages on the P800 at the same time. To facilitate language change, a PC utility is provided which enables the required language to be loaded on to the P800. Software Installation Utility This utility enables P800 applications to be installed from the PC. Dial-Up Networking Wizard This utility assists the user to create GPRS, HSCSD and CSD connection definitions in the Windows Dial-Up Networking folder. All the necessary information can be entered in a logical way. Set Infrared status to Modem in the Control Panel to use this facility over infrared. Other PC Suite for P800 Content • Interactive learning video • User Guide and Quick Guide documentation in local languages • Drivers for USB and using the P800 as a modem
P800/P802 White Paper, January 2003 94 Object Exchange – ‘Send As’ The P800 makes it possible to transfer objects over Bluetooth, infrared and Messaging. This is presented to the user via ‘Send As’ commands in applications. Simply select an item such as a contact, select ‘Send As’ and select the method to be used for sending. Typical applications are to beam an appointment to other people, or to receive a new background image.

Note that the P800 messaging application enables the user to add objects into EMS and MMS messages. See Messaging section. To perform a ‘Send As’ beam operation using infrared, the two devices are lined up and the sender initiates the transfer. To beam over Bluetooth, a scan finds the other devices within range. The user can then select the required device and send the information across. When sending over SMS, MMS or E-Mail, the required message type is created with the selected object attached. It is then sent over the air.
P800/P802 White Paper, January 2003 95 GPRS, HSCSD and CSD Connections The introduction of GPRS (General Packet Radio Services) is one of the key steps in the evolution of today’s GSM networks for enhancing the capabilities of data communication. Data traffic is increasing enormously (over both wired and wireless networks), with the growth in demand for Internet access and services paralleling that for mobile communications. Users want access to the Internet while they are away from their offices and homes, and surveys have found that the vast majority of business professionals want the ability to send and receive E-Mail, browse the Web and transmit text and graphics on a portable device. That is why the main applications driving Mobile Internet development are E-Mail clients and Web browsers. The demand for high-speed Internet access will be the key driver for coming generations of wireless services, and GPRS can deliver the necessary speed. GPRS allows innovative services to be created, enabling new and previously inaccessible market segments to be addressed and increasing customer loyalty. GPRS applications can be developed as both horizontal and vertical. Vertical applications are specific, including those for operations such as reaching police and emergency, taxi, delivery or automated services (vending machines, supervision, vehicle tracking). Horizontal applications are more generic and include those for Internet access, E-Mail, messaging, e-commerce and entertainment. GPRS is able to take advantage of the global coverage of existing GSM networks. Applications developed for GPRS can be deployed on a large scale and can reap the associated benefits. GPRS also provides a secure medium for connections to private networks, banking and financial services. The P800 supports connection to the internet, company intranets and mobile operator WAP services over GPRS, HSCSD and CSD. These will be explained in more detail later in this paper. A typical configuration will be to use GPRS for a continuous connection to the net. With GPRS, the P800 sends data in “packets” at a very high speed. The P800 remains connected to the network at all times, using transmission capacity only when data are sent or received. This enables E-Mail to be automatically fetched, whilst the browser is always available for immediate use. Third Party applications such as instant messaging clients will also benefit from a GPRS ‘always on’ connection. Using the P800 as a Modem The P800 contains a complete GSM/GPRS modem enabling it to be used to connect external devices such as laptop PCs to the internet or corporate intranet. The P800 is connected to the laptop using infrared, Bluetooth or cable, and will connect over the air using GPRS, HSCSD or CSD. Set Infrared status to Modem in the Control Panel to use this facility over infrared. The P800 appears to the laptop like a normal modem, having an AT command set compatible with industry de facto extensions and ETSI 07.07. Note that SMS and SMSCB are not supported over this channel. A Windows modem driver file is supplied on the PC Suite CD-ROM.
P800/P802 White Paper, January 2003 96 Once paired with a Bluetooth-enabled laptop, the P800 is ready to make an immediate connection to the Internet or corporate network. Because Bluetooth is wire-free and requires no line-of-sight alignment, laptop can be positioned for maximum comfort whilst the P800 can remain in a jacket pocket, briefcase or even be placed up to 10 metres away to get optimal reception. Infrared may also be used to link the P800 with other devices. Range is typically up to 1 metre. The two infrared ‘eyes’ must be kept in line of sight, at an angle of no more than approximately 30 degrees. Or a USB cable may be used.
P800/P802 White Paper, January 2003 97 Technical Explanation of CSD, HSCSD and GPRS This section provides an overview of the way data communication works in a GSM network environment. This will help you to understand the characteristics of the different solutions supported by the P800 and the parameters which govern the data transmission speeds available. Circuit Switched Data (CSD) A modem and landline is a common way to connect to the internet and company networks. The modem establishes a telephone call to the remote server which is ‘circuit-switched’, meaning that a telephone circuit is maintained for the duration of the connection, irrespective of whether data flows or not. The connection has a fixed bandwidth and is normally charged on a connected-time basis. In GSM networks, this facility is widely available and is called Circuit Switched Data (CSD). It is very similar to using a modem, but is subject to lower data transmission speeds due to the connection taking place over the GSM wireless network. The standard speed of operation for CSD is 9.6kbps transmit and receive. 14.4kbps is available in some GSM networks. The P800 will operate at the higher speed where it is available. The above diagram shows an end-to-end overview of a circuit switched data call via the GSM network. When establishing a data call, the P800 will be connected via the GSM network to what you may think of as a ‘modem’ within the network, rather like the GSM network is acting as a Circuit-Switched Network Server
P800/P802 White Paper, January 2003 98 wireless RS232 cable. The modem makes a PSTN or ISDN call to the Point Of Presence telephone number of the required resource, for example your Internet Service Provider or company modem pool for intranet access. Since the modem in the GSM network operates to common standards, no special configuration is required at the ISP or company remote access servers. The limitation on transmission speed (9.6kbps or 14.4kbps) is due to the lower bandwidth of the wireless connection from the P800 to the modem. As well as making data calls itself (built-in E-Mail, browsing and other applications), the P800 may be connected to a PC using USB cable, infrared or Bluetooth. In this case it acts like a modem. Either way, a standard CSD call Is limited to 9.6kbps or 14.4kbps. High Speed Circuit Switched Data (HSCSD) HSCSD operates in a similar manner to CSD, but allocates more radio capacity between the P800 and base station in order to increase the overall speed of the connection. Some explanation of the GSM system will help explain the characteristics of HSCSD. A GSM mobile phone making a voice call will digitise the speech into a very efficient compressed data stream. One radio channel has enough capacity to carry 8 of these data streams, so the channel is divided into 8 repeating timeslots. The phone is allocated a radio channel and timeslot and will send the data stream in bursts over that channel. Other phones in the cell may make use of the other timeslots in the channel. A separate receive channel and timeslot is allocated and works in the same way. When making a CSD call, the data is similarly sent in bursts over one of the 8 timeslots in the transmit channel. The basic data rate of this transmission is 9.6kbps, but some networks are upgraded to a data rate of 14.4kbps.
P800/P802 White Paper, January 2003 99 In the above example, terminal A is a phone using one timeslot for a voice call, terminal B is a P800 using one timeslot for a CSD data call and terminal C is a phone using one timeslot for a CSD WAP session. In each case, the timeslot is allocated whether data is transmitted or not. In order to achieve higher data rates, the GSM terminal may be allocated more timeslots within the transmit and receive channels. Since common applications such as browsing benefit from having high data receive rates without requiring high transmit rates, HSCSD configurations are typically asymmetric, meaning that data speed in one direction (receive) is higher than the data speed in the other (transmit). This also saves battery life. The slot allocation and hence the speed is set by the GSM network when the call is initiated, and may be dynamically altered depending on network conditions such as the number of active users in each cell. In the above example, the P800 (terminal B) has been allocated 2 receive timeslots. The HSCSD maximum data rates (kbps) using the P800 are shown below. 9.6kbps per timeslot 14.4kbps per timeslot Rx 19.2 28.8 Tx 9.6 14.4 The timeslot usage is not linked to demand from applications – an HSCSD connection will be maintained even if no data is flowing. The data ‘pipe’ is (as far as practicable) maintained fully open for you whether data flows or not. HSCSD connections are typically charged by connection duration in the same way as CSD calls.
P800/P802 White Paper, January 2003 100 Here is a summary of the slot usages in HSCSD. One ‘uplink’ and 1 to 2 ‘downlinks’. Analogue and ISDN (V110) Bearer Service Types CSD and HSCSD are capable of Analogue and, where supported by the mobile operator, ISDN connections. ISDN offers faster call set-up time and can increase the performance of an HSCSD connection due to the limitations in analogue modem technology. The simplest option is to test ISDN bearer mode, and switch to analogue if no connection can be made. Note that due to network limitations, analogue is often the only bearer that works when the user is roaming. GPRS GPRS mode combines the speed advantages of multi-timeslot working with packet data efficiency. Instead of utilizing a constant stream of timeslots in a circuit-switched call, GPRS mode sends/receives data in small packets, as needed, much like IP on the internet. Capacity is only used when data is being sent or received, which means that it is possible to be “constantly” connected so that applications have immediate access to networked servers. The radio resources are shared between users in a much more efficient way than is possible using circuit-switched methods – timeslots are dynamically allocated to those users who are transmitting and receiving data. The service is typically charged by the amount of data transferred. Connection set-up is fast and the P800 will normally be left connected for the whole time it is switched on. When applications need to transfer large amounts of data such as files, images etc, it is possible to increase bandwidth by using more timeslots for the duration of the transfer. The P800 supports up to 4+1 timeslots receive + transmit. The GSM network will dynamically allocate timeslot resources depending on current network conditions. Server
