• GSM 900 / DCS 1800 band

• GPRS capability

• Bluetooth connectivity

In case the RF tester i s not suitable for GPRS tests, GSM900/DCS1800 test may be consider ed as suf ficient
provided that the sensiv ity tests are strengthened by reducing the RF level down to -104dBm.

7.8 W@P Introduction

The purpose of W@p (Wirel ess Application Protocol) is to enable easy and fast delivery of relevant informati on and
services to m obile users. However, mobile Internet does not mean navigating on the Internet wit h a wireless devic e
but rather to access to some services in a mobile context.

The W@P architect ure was designed to enable standard Internet servers to provide servi ces to wireless dev ices.
The W@P wireless protocol is based on Internet standards such as HTTP and TLS but has been optimized
according to the c onstr aints of the wireless terminals: low memory capacity, small screen size

and of the network: limited bandwidth.

The W@P architect ur e is made up of 4 tec hnological parts which are necessary for accessing W@P services on a
mobile phone. These are:

W@P navigator or br owser
Mobile operator network
W@P gateway / W@P server
Web server

Customer Gateway Server

Answer

* 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 hav e to be set in t he m obile phone in order to access W@P services . Howev er, there ar e two

cases depending on the commercial offer:

* Transceiv er sold v ia an oper ator package

- Parameters cannot be ac c essed f r om 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 fr om hi s/her oper ator to unlock the W@P settings.

- Parameters can be acc essed f r om the W@P settings menu of the mobile
phone:
The customer changes the W @P par am eters according to his/her own convenience.

* Retail transceiver

- Phones are configur ed by the manufacturer with no W@P parameter. The end user has
to ensure that the W@P f unctionality and a data/fax options hav e been subscribed.
The end user has also to set the W@P param eters by asking for them from
his/her operator or by usi ng par am eters of another company (available on
Internet, newspaper etc.)

7.9 GPRS Introduction

7.9.1 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.
Furthermor e, the GPRS uses wavebands att ri buted to t he GSM. that means a band i n the 900 MHz , t he 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 pri ncipl e, already hel d for exam ple

for the protocol X.25, allows to allocate to the other communic ations, t he time- outs of a first c ommunicati on (wait of
an answer to an Internet r equest 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 routi ng and the int r oduc tion of bridges to lean
on existing GSM networks.

This technol ogy, capabl e of supplying transf er 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 c hannel;

• The transmission rate is independent from rising and downward links.

7.9.2 S ervices / Possibiliti es / Limitations

Domains of application

While the WAP stops in the consultation of the Internet pages, the GPRS allows to widen the servi ce 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 transmi ssion rate of a standard GSM network in "connect ed" mode does not overtake 9, 6 kbit/s, ev en
14,4 kbit/s by establi shment of specifi c software. It is five tim es less fast compared t o the standard wired network,
which authorises 56 kbit/s with a V90 modem.

With the GPRS, a transmi ssion rate included between 40 and 115 kbit/ s is availabl e. 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 t he data as a multiplier of transmission rat e. In 3+1 multislots mode (three slots for the network
towards mobil e, and one slot for the mobile towards network), it allows a transmi ssion rate of 40 k bit/s with a CS2
coding scheme.

With (8+1)multi sl ots using the CS4 coding scheme, one achieves i n pr actic e 115 k bit/s (in theory 175 kbit/s).
GPRS re-uses the exi sting GSM infrastr ucture, notably by keeping the current network of base stat ions ( BTS),

upgrading the BTS software.

Average time t o send an E-m ail 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 (cl ass B) is foreseen for
the voice and the data i n not simultaneous m ode. The prof essional or industri al model (cl ass C) i s dat a exclusi v ely
(the air termi nal is used as a m odem ). Finally the up-market (class A ) is compati ble 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, thr ee new types of mobile terminal have been defined:
Class A terminal, which support s simultaneous cir c uit-switched and packed-switched t r aff ic;
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, whic h is attached either as a packed-switched or c ir c uit-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 t he downlink channel . 18 service classes are defi ned depending on
the number for support time slots.

Philips Fisio820 features GP RS Class B. With GPRS Class B, if you receiv e incoming call s whil e in the middle of a
data session, you receive a notification; and v ic e versa.

Philips Fisio820 is enabled to support GPRS up to Class10 (4Rx, 2Tx) [depending on networks developments].
GPRS Class10 enables to rec eiv e information at l east 4 times faster t han a standard G SM connection and to send
them 2 times faster. That is why GPRS Class 10 is particul arly suitable f or surfing on the WAP pages, exchangi ng
emails or using y our phone as a modem for Int er net surfing, Intranet br owsing or fi le transfer.

Philips Fisi o820 is SMG31bis - Coding schemes 1, 2, 3 et 4.

7.9.3 Technical characteristics

Circuit switched mode or virtual access

The first advant age of the GPRS is to allow a better use of the radio and technic al resources. While the GSM works
in "connected" mode, called also "circuit-switched" mode, the GPRS uses f or its part the virtual connection m ode.
In "virtual" mode, the resources are shared. The transmission channel is never allocated to a unique user, but
shared between sev eral users. Every user has it when he needs it and only in that case. The r est of the time they
are availabl e. The circ uit switched mode cor responds to t he f uncti oning of a GSM li ne or still a standard t elephone
line. It consists in establishing a physical link between two points or two correspondents. Once the number is
dialled, a circ uit is permanent ly all ocated to the comm unicati on, wit hout any sharing wit h the other c ustomers. T his
mode of functioning which does not take into account periods of silence, when no data is passed on, does not
optimise at its best t he r adio resources.

The GPRS puts in evidenc e the more important role of t he network administrat or. In a GSM infrastruc ture t he role
of the administ r ator amounts to affect physical resources at t he beginning of every c ommunication. With the GPRS,
its role is more im portant. It consists i n assigning, in real time, t he physical resources (memories and electroni c
circuit s), in m anaging 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 Stati ons Controller (BSC) should be doubl ed by a Packet Cont r oller Unit (PCU).
Then comes the path int ended for data packets, its composed of :

- The Serving GPRS Specific Node (SGSN) , equivalent of the Mobile Switch Controller ( MSC), which aims to
check subscribers register ing , to authenti cate them and to authorise the communications,

- The Access module (GGSN) to t he IP worl d (I nternet or Intranet).
GGSN and SGSN are described later.

In the mobile terminal, appears from the bottom to the top the following layers :

n

The physical layer, constituted of two functional sub-layers;

• The RF sub-layer, whic h m anage the radio operations of the terminal. It emits the data received fr om
the physical lay er. It dec odes the data coming from the base station (BTS) and transmits it to the
physical layer for inte r p r etation

• The physical layer produces the frames, those ones will be emi tt ed by the RF layer; about the frames
received from the network, it detects and corrects tr ansmission errors.

n

The MAC layer (or RLC for Radio Link Control) manages the radi o link between the terminal and the Base

Station (BTS) , t hat means re-em ission mechanisms in case of err or , the function of access controll er for
the radio resources when several air terminals are i n competition. The RLC can request the re- emi ssion of
a data packet ;

n

The higher layer SNDC (Sub-Network Dependant Conv er genc e) manages the mobility, t he ci pheri ng and

data compression.

GGSN : Gateway GPRS Support Node ,
The GGSN provides the int erface towards the external IP packet net works. Ac tually, from the external IP network’s

point of view, the GGS N acts as a router for the IP-addresses of all subscribers served by the GPRS-networks. T o
make this possible the GGSN exchanges routing information with the external net works and sets up connections
towards external networks. Similar to the SGSN, t he GGSN deals with session management, specifically the
connection t owards the external networks. Al so, as many SGS N can connect to one GGSN, it has to associate
subscribers to the r ight SGSN.

SGSN : Serving GPRS Support Node
The SGSN forwards incoming and outgoing IP packets addressed to and f r om a mobile station. It serves all GPRS-

subscribers that ar e located and attached within the geographic SGSN service area.. A subscriber may be served
by any SGSN in the GPRS network depending on location. The traffic is rooted from the SGSN to the BSC, via the
BTS to the mobile stati on. To make this packet traffic possible, signalling with several other nodes is necessary, for
instance the Home Location Register (HLR) , the Mobil e Switc hing Centre (MSC), the BSC and the GGSN, as well
Short Message Service-nodes (SMS). From these signalling connections the SGS N handles important GPRS
functions such as cipher ing and authentication, session management, mobility management and the logical link
management towards the mobile station.

Packets routing

The routing of ev er y packet is independent from the one who precedes it or by t he one who follows it. During the
connection phase of a GSM termi nal in a network, the signalling exc hanges are multiple, and to face the
constraints of the packet mode, the informati on of routing obtained to forward the first pac k et to a GSM terminal is
stored in the GGSN. So, the routing of following packets i s selec ted according the context stored in the GGSN ( the
Temporary Logical Link Identity or TLLI).

7.9.5 GPRS Attach and GPRS Detach procedur es
The procedure for a GPRS attach is made by the MS to the SGSN. After Havi ng executed a successful GPRS

attach, mobility management contexts are establi shed in the MS and the SGSN, setting the MS in the READY
state. The MS is then abl e to activate PDP-contexts. The procedur e of GPRS attach is illustrated below.

MS SGSN HLR

1. Attach Request

2. Authentication

3. Location Update

4. Attach Accept
Response

5. Attach Complete

GPRS attach procedure

1. The MS sends a GPRS attach request which includes the GPRS mobile cl ass and the multislot class.

2. Authentication is carried out in the same manner as with GSM, but instead of the MSC, it’s the SGSN that
sends the IMSI of the MS to the HLR, initiating the encryption al gori thm.

3. A location update procedur e stor es the c ur r ent SGSN of the MS in the HLR.

4. The attach accept response as si gns a Temporary Logical Link Ident ity (TLLI) to the MS.

5. A GPRS attach complete response from the MS to the SGSN confirms the attach.

After the authentication within the GPRS att ac h procedure, no additional authentication is r equired during the entire
GPRS-session. A GPRS detach will terminate the ongoing GPRS-session. This detach could be initi ated explicitly
by the MS or the SGSN, or implicitly when the STANDBY-timer runs out.

7.10 BLUETOOTH Introduction

7.10.1 Presentation
The Bluetooth t echnology eliminates the need f or wires, c ables and the corresponding connect or s betwee n

cordless or mobile phones, modems, headsets, PDAs, computers, printers, projec tors, and so on and paves the
way for new and complet ely diff er ent devices and applications.

The majority of radio systems in commercial use today are based on a cell ular radio Architectur e. A mobil e network
established on a wired backbone infrastructur e uses one or more base stations placed at str ategic positions to
provide local cell coverage; users apply portable phones, or more generic mobile terminals, to access the mobile
network; the terminals maintain a connection to the network via a radio link to the base stations. There is a strict
separation between t he base stations and the terminals. Once registered to the network, the terminals remain
locked to the control c hannels in the network, and connections can be established and released according to the
control channel pr otocols. Channel access, channel allocation, traffic c ontrol, and interference mi nimi z ation are
neatly controlled by the base stations.
