The T39 has built-in Bluetooth wireless technology Short-range radio links operate in a glo-
bally available 2 4 GHz radio frequency band, and ensures fast and secure communications up
to a range of 10 metres (typically) between devices Please note that in countries where the use
of Bluetooth wireless technology is not allowed, you must ensure that the Bluetooth function is
set to off Contact the Ericsson representative to check if the use of Bluetooth wireless technol-
ogy is restricted in your country
Bluetooth wireless technology is designed to be fully functional even in very noisy radio fre-
quency environments and it provides a high transmission rate All data transfer is protected by
advanced error-correction methods that ensure a high level of data security
Bluetooth wireless technology facilitates instant connections which are maintained even when
the devices are not within line of sight Bluetooth wireless technology facilitates high-quality
voice transmissions, even under severe conditions For example, you can connect your headset

The introduction of GPRS (General Packet Radio Services) is one of the key steps in the evolu-
tion of today’s GSM networks to enhance the capabilities for data communication Data traffic
is increasing enormously over both wired and wireless networks This growth in demand for
internet access and services has paralleled the explosion in demand for mobile communications
Users want access to the internet while they are away from their offices and homes The main
applications driving the wireless internet development are e-mail access, web browsing and pull
content, also known as web clipping User surveys have found that a vast majority of executives
and business professionals want wireless internet access to both send and receive e-mail on a
portable device, as well as web browsing with both text and graphic capabilities! The demand
for high-speed internet access will be the key driver for coming generations of wireless services
equal to, or faster than wired, and GPRS can deliver this mobile internet functionality GPRS
will allow innovative services to be created, enabling new and previously inaccessible market
segments to be addressed, increasing customer loyalty and reducing churn Machine-to-machine
and person-to-machine communications will become possible
GPRS applications can be developed both as horizontal and vertical applications Vertical appli-
cations can for example be operations like police and emergency, taxi, delivery or automated
services such as vending machines, supervision, vehicle tracking Horizontal applications are
generic, such as internet access, e-mail, messaging, e-commerce and entertainment One of the
advantages with GPRS is that it will profit from the global coverage of existing GSM networks
Therefore applications developed for GPRS can be deployed on a large scale and will gain
economies of scale GPRS also provides an ideal secure medium for connections to private net-
works, banking and financial services
The T39 supports GPRS, which means that the data is sent in packages at a very high speed The
phone remains connected to the network all the time without using any transmission capacity,
until data needs to be sent or received This illustration gives a comparison
•1 A normal GSM call only uses one of eight repeating time slots in the GSM channel, giving a
data speed of 9,600 bps The T39 supports a more efficient coding scheme, giving data
speeds of up to 14,400 bps (providing the network supports this) Furthermore, High Speed
Circuit Switched Data (HSCSD) gives the possibility to use two time slots for receiving
data This can increase the data speed up to 28,800 bps (network-dependent)
•2 In GPRS, data is sent in packets, and up to three time slots can be combined to provide the
necessary bandwidth, up to 39,600 bps for receiving data, depending on coding scheme

Instead of occupying a whole voice channel for the duration of the call, data is sent in small
packets as needed, just like IP on the internet Capacity is used only when data is being sent or
received, which means that it is possible to be “constantly” connected, as required by the appli-
cation in use If the user wants to send e-mail, it may be sufficient to share a channel with sev-
eral other users On the other hand, the phone has access to several time slots if a higher
capacity is needed
The GPRS specification includes four coding schemes with different data speeds The T39
works with the first two coding schemes, but the data speed will naturally vary according to net-
work configuration
The GSM system's design limits the ability to use all eight time slots Instead, the T39 uses up to
three time slots for receiving data, and one slot for transmitting This means the speed for
receiving data is up to 39,600 bps and for sending data up to 13,200 bps
Information about the identity of phone and the characteristics of the connection are described
in the PDP context (Packet Data Protocol context) This information is stored both in the phone
and in the mobile network, so that each phone is identified and “visible” to the system In T39,
multiple PDP context settings can be set via the menu system, or by OTA provisioning
Using GPRS with the T39 gives several advantages, for example:
Constant connection Keep an open connection to the e-mail system or the company net-
work, staying online to receive and send messages at all times All con-
nection settings can be managed by using the Data connections feature
High speed Gain access automatically to increased bandwidth when downloading
large files, images etc
Cost efficient GPRS being an IP-based connection means that a high transmission
capacity is only used when needed This makes it possible to stay con-
nected via GPRS, whereas keeping a constant circuit switched connec-
tion would be more expensive
WAP over GPRS Access the internet via WAP at high speed and with a constant connec-
tion The user can run the WAP functions such as browsing
E-mail over GPRS This means that the user can be connected to the e-mail system while
reading and preparing messages, and that the messages are sent at a
high speed
Data communication Using GPRS, this provides data and internet/Intranet access, for a PC,
PDA or handheld device connected via Bluetooth wireless technology,
infrared or cable
Data and voice The T39 can maintain a data connection when conducting a voice call
For example, the user can conduct voice calls while maintaining an
uninterrupted connection to an e-mail system
Provide settings The GPRS configuration settings can be sent from the provider over
the air, OTA This way, the user can use GPRS without making any set-
tings in the phone
User controlled settings Full user control is enabled in the T39 In the Data connections menu,
the user can set up multiple descriptions and access advanced settings
for GPRS, for example Data compression and Quality of Service

The typical WAP client is a small, portable device which is connected to a wireless network
This includes mobile phones, pagers, smart phones, PDAs and other small devices In these
devices, you have a limited user interface, low memory and computing power compared to
desktop and laptop computers
The WAP browser in the T39 is compliant with WAP June2000 (WAP 1 2 1) includes WTLS
class 3 and mechanisms for digital signatures It is designed for WML and cannot read ordinary
HTML pages, but it is suitable for interaction with customer services, e g ticket reservation It
is also handy when you want to access text-based information, such as timetables, share prices
and exchange rates and internet banking and other interactive services
The built-in WAP browser gives the user portable, fast and secure access to a wide variety of
services, with the possibility of personalized services WAP in the T39 offers new opportunities
to companies and service providers:
Push service A useful feature for companies and service providers to push contents
or service indications to work groups or customers This is used for
notifications, mail alerts, messaging, news, stock quotes, contacts,
meeting requests, games etc
Provide settings Using SMS message, configuration settings can be sent over the air,
OTA, so that the user does not need to configure the WAP access set-
tings manually WAP settings may also be customized by the operator
Adapt to phone type When creating a WAP service, you want to make sure that the user
experience is what you intended, regardless of client device type The
function User Agent Profile is supported by the T39 to allow the con-
tents to be automatically optimized for the phone
Security Service providers can offer commercial and business critical services
with high security to mobile users, compliant with Wireless Transport
Layer Security (WTLS) class 1, 2 and 3 Digital signatures and Wire-
less Identification Module (WIM) are supported in the T39 The WIM
is used to store security related information
Several bearer types The T39 accesses WAP over a standard GSM Data connection as well
as over a GPRS connection SMS is available as bearer type also (Net-
work-dependent services )
Bandwidth efficiency One of the key advantages WAP has over text-based HTML pages on
mobile devices, is the bandwidth efficiency for communication This is
due partly to the fact that the WAP application is communicated to the
wireless devices in the form of binary encoded data Over a GPRS con-
nection, bandwidth is used even more efficiently See “Using GPRS In
The T39” on page 11

Easy create for WAP Creating a WAP service is no harder than creating an Intranet/internet
service today since WML and WMLScript are based on well-known
internet technology New market segments can be addressed by
launching innovative mobile Value Added Services
Using standard tools It is possible for the service creator to use standard tools like ASP or
CGI to generate content dynamically You can utilize existing invest-
ments in databases etc that are the basis of existing internet services
Create a service once and make it accessible on a broad range of wire-
less networks
Maintain customer base You can adapt existing internet services to WAP The actual binary
encoding can be handled by the WAP Gateway which makes it possible
to create WAP applications using the text-based language WML and
other tools In fact, existing HTML-based applications on the internet
can be viewed in the WAP browser, if an automatic conversion is per-
formed in the WAP Gateway
Improve productivity Improve and simplify the communication flow within an organization
by making information available to mobile users A company or orga-
nization can use a WAP gateway to provide a secure connection to the
company network for their users
The WAP profiles The T39 holds five WAP profiles, each with a group of network set-
tings and a home page If you provide a corporate WAP service on your
Intranet, it is useful to enter an Intranet WAP profile in user phones
The WAP profile holds network settings and user identification The
users switch easily between the corporate services and WAP services
on the internet, simply by switching WAP profile

14
The phone accesses WAP services over SMS or IP, where IP can be provided either over GSM
Data or GPRS depending on network services
Typical differences which distinguish the bearer types are listed below
GG
GGPP PPRR RRSS SS AA AAcc cccc ccee eess ssss ss
• The connection is maintained “constantly”, as required by the application, and data is trans-
mitted in packets This means that the phone is connected almost all the time without using
network capacity
• Higher transmission speed than with GSM Data and SMS access
• Pricing of GPRS can be dependent on the actual use of bandwidth, which means very low
cost when no data is sent or received, while the phone remains connected to the WAP ser-
vice
• When transmitting large amounts of data, bandwidth can be increased automatically to allow
faster transmission speed
• GPRS is ideal for Complex Pull services, Browsing, Data transfer, Provisioning, Pager ser-
vice, Messaging services, Info services, Push initiations
GG

• Circuit connection of data call which means that the phone is connected during the entire
WAP session
• Comparably higher transmission speed than with SMS access
• Pricing of GSM Data access can be compared to pricing of data calls in the network
• GSM Data is suitable for Complex Pull services, Browsing and Data transfer
• GSM Data is not suitable for Provisioning, Pager service
SS
SSMM MMSS SS AA AAcc cccc ccee eess ssss ss
• SMS point-to-point is used and not SMS Cell Broadcast
• The connection is maintained by the automatic exchange of ”messages” between the phone
and the SMS Service Center
• Comparably lower transmission speed than with GSM Data access
• Pricing of SMS access can be compared to pricing of the normal SMS service in the net-
work
• SMS is suitable for Messaging services, Info services, Push initiations, Provisioning
• SMS is not suitable for Browsing, Data transfer
The WAP Gateway provides services in the company’s Intranet, a banking or stock trading ser-
vice on the internet, or access to other WAP applications on web addresses anywhere on the
internet A Gateway is identified by an IP number or by a phone number, depending on access
type

When using certain WAP services the user may want a secure connection between the phone
and the WAP gateway, for example when using banking services An icon in the display indi-
cates when a secure connection is used The T39 is based on the WAP June2000 (WAP 1 2 1)
specifications where security functionality is specified with a technology called Wireless Trans-
port Layer Security (WTLS)
The WAP protocols that handle the connection, its transport and its security are structured in
protocol layers The security is handled by the WTLS layer operating above the transport proto-
col layer There are WTLS classes that define the levels of security for a WTLS connection:
• WTLS class 1 involves encryption with no authentication
• WTLS class 2 involves encryption with server authentication
• WTLS class 3 involves encryption with both server and client authentication
Server authentication Requires a server certificate stored at the server side and a root certifi-
cate stored at the client side
Client authentication Requires a client certificate stored at the client side and a trusted certif-
icate stored at the server side
A Wireless Identity Module (WIM) can contain both trusted and client certificates, private keys
and algorithms needed for WTLS handshaking, encryption/decryption and signature generation
The WIM module can be placed on a SIM card and will then be referred to as a SWIM card
CC
CCee eerr rrttttiiiiffffiiiicc ccaa aattttee eess ss
To use secure connections, the user needs to have certificates saved in the phone There are two
types of certificates:
Trusted certificate A certificate that guarantees that a WAP site is genuine If the phone
has a stored certificate of a certain type, it means the user can trust all
WAP gateways that use the certificate Trusted certificates can be pre-
installed in the phone, pre-installed in the SWIM, or downloaded from
the trusted supplier’s WAP page
Client certificate A personal certificate that verifies the user’s identity A bank that the
user has a contract with may issue this kind of certificate Client certif-
icates can be pre-installed in the SWIM card
WW
WWIIIIMM MM LL LLoo oocc cckk kkss ss (( ((PP PPIIIINN NN CC CCoo oodd ddee eess ss)) ))
There are two types of WAP security locks (PIN codes) for the WIM on SIM The locks protect
the subscription from unauthorized use when browsing The locks should typically be supplied
from the supplier of the SWIM
Access lock An access lock protects the data in the WIM The user is asked to enter
the PIN code the first time the SWIM card is accessed when establish-
ing a connection
Signature lock A signature lock is used for confirming transactions - like a digital sig-
nature
In the T39, the user can check which transactions have been made with the phone when brows-
ing Each time the user confirms a transaction with a signature lock code, a contract is saved in
the phone The contract contains details about the transaction

To simplify configuring WAP settings in a number of phones, all settings can be sent as an SMS
message to each phone This makes it easy for an operator, a service provider or a company to
distribute settings for internet/Intranet, and WAP, without having to configure each phone man-
ually This also makes it easy to upgrade the services provided to the users, without the need for
users to perform any manual configuration
• The OTA configuration message is distributed via SMS point-to-point
• The setup information is a binary encoded XML message, according to WBXML To
receive information about OTA specifications, please contact your local Ericsson representa-
tive for consumer products A configurator that utilizes OTA provisioning can be tested on
the Ericsson Mobile Internet
• The user is not alerted about new settings until the ongoing browsing session ends Further-
more, settings are not changed during an ongoing browsing session
• The necessary user interaction is limited to receiving and accepting/rejecting the configura-
tion message, and selecting which WAP profile to allocate the settings to
• Security can be handled using a keyword identifier displayed on the screen as a shared secret
between the SMS sender and the receiver It is important that the user has a way to verify
that the configuration message is authentic
An easy way to perform the WAP configuration of a single phone is by using the step-by-step
WAP configurator provided on the Ericsson Mobile Internet The configurator utilizes OTA pro-
visioning, and it is available on http://mobileinternet ericsson com, no login required
Another way to perform the WAP configuration of a single phone is by using the Ericsson
Phone Settings program which is available on the CD supplied with the phone There, you can
find all configuration settings needed for the phone to access the WAP services

The T39 is capable of sending and receiving SMS messages, linked messages and it supports
Enhanced Messaging Services (EMS) Please note that EMS is only valid for T39m versions
• With the Short Message Service, a user can send text messages containing up to 160 charac-
ters to and from GSM mobile stations (up to 70 characters using Chinese text)
• Status report is supported, which means that the user can see if a sent message has been
delivered or not (network-dependent service)
• With the linked SMS, the user can link several SMS messages together to create a longer
message (network-dependent service)
• With EMS, the T39 lets the user insert sounds, pictures and melodies, or ring tones in outgo-
ing messages Also, the phone will display pictures and play melodies, sounds and anima-
tions included in incoming messages (network-dependent service, and only valid for T39m
versions)
The T39 also lets you save often-used text messages as templates You can save up to ten tem-
plates consisting of up to twenty-five characters each in the phone's memory The T39 also fea-
tures an SMS counter allowing you to keep track of SMS messages that you have sent
Enhanced Messaging Service (EMS) is a powerful enhancement of the SMS standard specified
by the 3rd Generation Partnership Project (3GPP) It is supported by the major network opera-
tors and mobile phone manufacturers With it, mobile phone users can add life to SMS text mes-
saging in the form of pictures, melodies, sounds, animations and formatted text This gives the
users new ways to express feelings, moods and personality in SMS messages
Add life to messages to and from the T39 by inserting melodies.
Users can express feelings and personality by inserting pictures in messages.
As well as messaging, users will enjoy collecting and swapping pictures and ring signals and
other melodies, downloading them from the internet or editing them directly on the phone See
related documents listed under “Documents” on page 25 EMS is a network-dependent service
One message may contain several EMS objects, such as a picture, an animation and a sound
The message is limited by size If concatenation is used, up to six segments of 128 bytes each
can be combined in one message
Most phones without support for the EMS standard will simply ignore the EMS information
when the message is received, and will just display the text in the message This prevents the
phone from displaying unreadable contents to the user

The Mobile Internet offers much more than mobile access to the internet - it opens up a whole
new range of situation-based services Services that give us anytime, anywhere access to per-
sonalized communications, information and entertainment The T39 is built to facilitate the use
of and access to services on the internet The T39 also enables new technologies such as mobile
positioning to create new commercial and productivity solutions
In order to browse via WAP or use the e-mail program or an internet connection, the user must
have a connection for data communication configured in the phone Such a connection is called
a Data connection A Data connection contains specific settings and parameters for the connec-
tion, for example, the address to the appropriate server Several Data connections can be saved
in the T39, with different settings To make it easier for the user, the Data connections can be
provided by the operator in a message over the air, OTA provisioning
Advantages of Data connections include:
• Once the data connections are defined and named, the user does not have to enter the set-
tings for the connection again
• Data connections can be re-used at any time
• When working with WAP, e-mail or the internet, the user simply selects which Data connec-
tion they want to use for the activity
• Data connections are used for both GSM Data and GPRS connection settings
• Data connections contain choice of bearer type for WAP and corresponding bearer specific
parameters
• Data connections contain all settings for the internet access point, whether a modem pool
phone number or an IP address, and the user ID and password
The T39 has a built-in e-mail client for sending and receiving e-mail messages This means that
users can connect to the e-mail account normally used on the corporate network, or another e-
mail service as preferred The same settings as those on the office PC can be used in the e-mail
client on the user’s T39 The e-mail client has several useful features:
• A true POP3/SMTP e-mail client, it supports the majority of e-mail and web-mail servers
• Copy of outgoing mail can be sent to the corporate e-mail server for future reference
• The user can attach a photo from a digital camera
• Automatic e-mail check at regular intervals selected by the user
• More than one e-mail account in the phone, for example, one for your business e-mail and
one for your private e-mail
• Predictive text input (T9 Text Input) facilitates typing text in e-mail body, address and sub-
ject
