7.10 W@P Introduction
The purpose of W@p (Wireless Application Protocol) is to enable easy and fast delivery of relevant information and
services to mobile users. However, mobile Internet does not mean navigating on the Internet with a wireless device
but rather to access to some services in a mobile context.
The W@P architecture was designed to enable standard Internet servers to provide services to wireless devices.
The W@P wireless protocol is based on Internet standards such as HTTP and TLS but has been optimized
according to the constraints of the wireless terminals: low memory capacity, small screen size
and of the network: limited bandwidth.
The W@P architecture is made up of 4 technological parts which are necessary for accessing W@P services on a
mobile phone. These are:
W@P navigator or browser
Mobile operator network
W@P gateway / W@P server
Web server
Customer Gateway Server

* Subscription
The customer has to contact his Network Operator to inquire about his subscription and the options he can
subscribe to. Generally the customer just have to request his W@P access to his provider and he will not be
charged for that.
* W@P parameters
Parameters have to be set in the mobile phone in order to access W@P services . However, there are two
cases depending on the commercial offer:
* Transceiver sold via an operator package(with subscription included):
- Parameters cannot be accessed from the W@P settings menu of the mobile phone:
The transceiver is W@P locked. The W@P connections will always be made from the
operator W@P homepage and search engines will be available. The customer will have to
ask for a password from his/her operator to unlock the W@P settings.
- Parameters can be accessed from the W@P settings menu of the mobile
phone:
The customer changes the W@P parameters according to his/her own convenience.
* Retail transceiver(without subscription included):
- Phones are configured by the manufacturer with no W@P parameter. The end user has
to ensure that the W@P functionalities and a data/fax options have been subscribed.
The end user has also to set the W@P parameters by asking for them from
his/her operator or by using parameters of another company (available on
Internet, newspaper etc.)
Detailed parameters
Phone Number (or dial-up number) : to establish a connection with the Internet Service Provider
Login (or User Name) : if requested by your ISP
The password : if requested by your ISP
IP address for the Gateway : for communications between Internet Service Provider and Gateway
& Port Number (for a secure or non secure connection)
Home page address(or URL address): for communications between Gateway and Web server
Please note that it is important to respect small and capital letters according to your operator instructions.
It is also possible that your provider does not require the Login and/or Password.

7.11 GPRS Introduction
7.11.1 Presentation
The GPRS does not constitute to him alone a separate mobile network, but a supplementary layer added to a
existing GSM network.
It can be thus settled without any supplementary license. This means that all the operators who have a GSM
license can develop their network towards it.
Furthermore, the GPRS uses wavebands attributed to the GSM. that means a band in the 900 MHz, the other one
in the 1800 MHz and finally the third for the USA, in the 1900 MHz
The GPRS, also called GSM 2+, rests on the transmission of data packets. This principle, already held for example
for the protocol X.25, allows to allocate to the other communications, the time-outs of a first communication (wait of
an answer to an Internet request for example).
Conceived to reuse at most the existing GSM infrastructures, the expansion of the GPRS requires the
implementation of a network infrastructure based on the data packets routing and the introduction of bridges to lean
on existing GSM networks.
This technology, capable of supplying transfer rates rising up to 115 kb/s (against 9,6 kb/s for the GSM), offers
interesting features:
•Several channels can be allocated to a single user;
•Several users can share a single channel;
•The transmission rate is independent from rising and downward links.
7.11.2 Services / Possibilities / Limitations
Domains of application
While the WAP stops in the consultation of the Internet pages, the GPRS allows to widen the service offer. Besides
the access to Internet (or Intranet), from the traditional mobiles phones, it allows a better access to e-mails
containing joined files.
A rate higher than the wired public network
Today, the transmission rate of a standard GSM network in "connected" mode does not overtake 9,6 kbit/s, even
14,4 kbit/s by establishment of specific software. It is five times less fast compared to the standard wired network,
which authorises 56 kbit/s with a V90 modem.

With the GPRS, a transmission rate included between 40 and 115 kbit/s is available. Everything depends on the
number of virtual canals or " time slots " used, and on coding scheme (CS1 to CS4). GPRS acts on the
compression of the data as a multiplier of transmission rate. In 3+1 multislots mode (three slots for the network
towards mobile, and a slot for the mobile towards network), it’s allows a transmission rate of 40 kbit/s with a CS2
coding scheme.
With (8+1)multislots using the CS4 coding scheme, one achieves in practice 115 kbit/s (in theory 175 kbit/s).
If, as it seems to be the current will of the operators, GPRS re-uses the existing GSM infrastructure, notably by
keeping the network of current base stations ( BTS), upgrading the BTS software.
Average time to send an E-mail with a 10 pages attached document :
Standard Rate Time elapsed
Current GSM 9,6 kbit/s 7 min.
Standard Modems (V90) 57,6 kbit/s 70 sec.
RNIS 128 kbit/s 31 sec.
GPRS 144 bit/s * 28 sec.
EDGE 384 kbit/s * 10 sec.
UMTS 2 Mbit/s 2 sec.
* : in optimal conditions
Three types of air terminals
Three types of air terminals were defined to meet the needs of the GPRS: the basic model (class B) is foreseen for
the voice and the data in not simultaneous mode. The professional or industrial model (class C) is data exclusively
(the air terminal is used as a modem). Finally the up-market (class A) is compatible voice/data simultaneously. This
class A terminal is problematic. The power of calculation required at the moment has a strong incidence on its
production cost and makes it dissuasive.
In the GPRS standard, three new types of mobile terminal have been defined:
Class A terminal, which supports simultaneous circuit-switched and packed-switched traffic;
Class B terminal, which supports either circuit-switched or packed-switched traffic (simultaneous network
attachment) but does not support both kinds of traffic simultaneously;
Class C terminal, which is attached either as a packed-switched or circuit-switched terminal.
The terminal types are further differentiated by their ability to handle multislot operations. The terminal can use
from 1 up to 8 time slots on the uplink and on the downlink channel. 18 services classes are defined in function on
the number for support time slots.

Philips Fisio620 features GPRS Class B. With GPRS Class B, if you receive incoming calls while in the middle of a
data session, you receive a notification; and vice versa.
Philips Fisio620 is enabled to support GPRS up to Class10 (4Rx, 2Tx) [depending on networks developments].
GPRS Class10 enables to receive information at least 4 times faster than a standard GSM connection and to send
them 2 times faster. That is why GPRS Class10 is particularly suitable for surfing on the WAP pages, exchanging
emails or using your phone as a modem for Internet surfing, Intranet browsing or file transfer.
Philips Fisio620 is SMG31bis - Coding schemes 1,2,3 and 4.

7.11.3 Technical characteristics
Circuit switched mode or virtual access
The first advantage of the GPRS is to allow a better use of the radio and technical resources. While the GSM works
in "connected" mode, called also "circuit-switched" mode, the GPRS uses for its part the virtual connection mode.
In "virtual" mode, the resources are shared. The transmission channel is never allocated to a unique user, but
shared between several users. Every user has it when he needs it and only in that case. The rest of the time they
are available. The circuit switched mode corresponds to the functioning of a GSM line or still a standard telephone
line. It consists in establishing a physical link between two points or two correspondents. Once the number was
dialled, a circuit is permanently allocated to the communication, without any sharing with the other customers. This
mode of functioning which does not take into account periods of silence, when no data is passed on, does not
optimise at its best the radio resources.
The GPRS puts in evidence the more important role of the network administrator. In a GSM infrastructure the role
of the administrator amounts to affect physical resources at the beginning of every communication. With the GPRS,
its role is more important. It consists in assigning, in real time, the physical resources (memories and electronic
circuits), in managing the radio resources, and in affecting them according to the demand.
The GPRS settles down on the existing GSM network
The GPRS-system is built upon the existing GSM-infrastructure. Basic stations undergo no modification with
exception of the specific software, that can be installed by downloading.
Next, the Basic Stations Controller (BSC) should be doubled by a Packet Controller Unit (PCU).
Then comes the path intended for data packets, its composed of :
- The Serving GPRS Specific Node (SGSN) , equivalent of the Mobile Switch Controller ( MSC), which aims to
check subscribers registering , to authenticate them and to authorise the communications,
- The Access module (GGSN) to the IP world (Internet or Intranet).
GGSN and SGSN are described later.
