6.0 TEST AND INSPECTION PLAN

The test plan is derived from the Product Test Reference of FISIO 620 and FI SIO 625.

6.1 User Interface Test

Use the Test SIM Card « SP »/ Production t o test t he transceiver s as f ollows :

• On/Off button

• LCD Backlight

• Keyboard Test

• Buzzer Test

• Vibrator Test

• Audio Test

• Antenna

• LCD

• IMEI

• Tester Status/ E epr om Status

Test ( to measure the radiated power level. Not necessary when using an antenna coupler)

With a fast Charger connected with the PRODUCT’s bottom connector, check the full scrolling f rom one mode to the next when charging IG N (Ignition) – Battery.

6.2 RF Test

The radio test must be performed with a Digital Radio Test Set. The mobile has to be set on the antenna coupler inside the shielded chamber.

Or It can be tested using the Cr adle (in this case a measurement of the power radiated by the antenna has to be performed)

Use the Test SIM Card « SP »to test the following RF items

• GSM 900 / DCS 1800 band

• GPRS capability

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.

RRM

RLC / MAC

This reasoning i s based on the fact that all the protocol steps (GP RS att ac h, GPRS detach, …) are achieved on the GSM/DCS bands and validated by Philips Approval department.

The new parameter to chec k , int r oduc ed by GPRS, would be BLER (Blocks Error Rate).

7.10 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

* 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.

(with subscription included):

- 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 unctionalities and a data/fax options have 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.)

7.11 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. 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.

7.11.2 Services / Possibilities / Limit ations

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 a slot for the mobil e towards net work), it’s allows a transmission r ate of 40 kbit/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). If, as it seems to be the current will of the operators, GPRS re-uses the ex isting GSM infrastructure, notably by

keeping the network of current base stations ( BTS), upgrading the BTS software.

Average time t o send an E-m ail with a 10 pages attached document :

* : 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 f or 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 servic es cl asses are defined i n f uncti on on the number for support time slots.

Philips Fisio620 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 Fisio620 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. T hat is why GPRS Class10 is partic ularly suit able for surfing on the W AP pages, ex changing emails or using y our phone as a modem for Int er net surfing, Intranet br owsing or fi le transfer.

Philips Fisi o620 is SMG31bis - Coding schemes 1,2,3 and 4.
