Characteristic of

Mobile Services :

What Make Them Different?

Background

Mobile services will be very different from traditional telecomservices ( voice ? )

Mobile services will be very similar to the fixed Internetservices ( speed, trial and error, rapid innovation )

A typical mobile operator in Y2000 run 10-20 services ( basic

voice call, international call, roaming call, data access/PC,SMS, numbering plan, friends and family pricing plan . ? )

In the future, the operator will managethousands of services.

Why do we need packet data ? In Circuit Switched Data, the data rate and delay can be

guaranteed and therefore is ideal for real time services such asvideo transmission.

GPRS on the other hand is more suited to bursty traffic such asweb browsing and telemetry and the provision of some newnetwork elements is necessary to provide these services.

When compared to Circuit Switched Data, GPRS has a numberof advantages when it comes to Internet connections and linkswith other packet switched networks.

GPRS : Wireless Packet Data


47/243

47

Packet Data

If a user use a circuit data and want to be always on-line,

he needs to monopolize a radio channel ( and pay for it ! ),

even when he does not send any data

With packet data, a user can stay connected ( always on-line ) and pay only for the amount of data that he

send/receive

GPRS In circuit switching each time a connection is required between

two points, a link between the two points is established and the

needed resources are reserved for the use of that single call forthe complete duration of the call.

In packet switching, the data to be transferred is divided up into

packets, which are then sent through the network and re-

assembled at the receiving end. GPRS is added to the GSM system in order to offer an efficient

data service, i.e. GPRS offers a fast interface from the radio

network towards a packet switched network

The more important GPRS networks elements are the ServingGPRS Support Node (SGSN) and the Gateway GPRS Support

Node (GGSN).


52/243

52

GPRS handsets Class A terminals : they can handle packet data and

voice at the same time

Class B terminals : they can handle both packet data

and voice, but not at the same time Class C terminals : they can only handle either voice

or data


53/243

53

GPRS

In theory the throughput of GPRS is 170 kbps maximum ( 8timeslots, one timeslot carry 9-20 kbps )

Example of Configuration of GPRS terminal :

4+1 = 4 downlink timeslots and 1 uplink timeslot

2+1 = 2 downlink timeslots and 1 uplink timeslot etc

Problem in GPRS terminal :

Number of transmitting equipment

Usage of battery : power consumption

Heat generation

Cost


54/243


55/243

Communicating with GPRS

Users GPRS applications are IP applications

Their behavior are similar to LAN applications

We dont call GPRS user, but we send IP packets

Most GPRS applications are client/server based

If we can make an application for LAN, we can make it

work in GPRS

The challenge is how to make it efficient to work inwireless network

Speed and Capacity

The real speed of GPRS depend on :

Number of voice and other packet data in the same cell

Number of timeslots that the mobile can support

Planning is critical to efficient use of time. E.g. seewhat the team members are doing to try to find acommon time for a meeting

Postpone : Making last minutes change or last minutedecision.

Filling time : doing things with sudden idle time, e.g.reading e-mail while waiting at airport, read the newsin the taxi

Catching up : trying to recover lost time, e.g. reading

yesterdays newspaper Multi-tasking : to do multiple things at the same time

Real-time : delivering services when they occur ( stockprice information )

SEJARAH CDMA


152/243

152

SEJARAH CDMA

Teknologi CDMA pada awalnya dipergunakandalam komunikasi radio militer Amerika Serikat(AS), mulai tahun 1990 patennya diberikan

kepada Qualcomm, Inc. dan dijadikan sebagaistandar seluler digital di AS sejak tahun 1993.Oleh karena itu tidak heran jika teknologi inisangat aman karena tidak dapat digandakan(dikloning). Sehingga teknologi ini sangat cocokbagi kegunaan layanan telepon banking, sepertitransfer, cek saldo, dll.

Apa itu cdma?


153/243

153

Apa itu cdma?

CDMA (code division multiple access) adalahteknologi akses jamak dimana masing-masing usermenggunakan code yang unik dalam mengakses

kanal yang terdapat dalam sistem. Pada CDMA, sinyal informasi pada transmitter

dicoding dan disebar dengan bandwidth sebesar1.25 MHz (spread spectrum), kemudian pada sisi

repeater dilakukan decoding sehingga didapatkansinyal informasi yang dibutuhkan.

Teknologi CDMA IS- 95

CDMAOne menyediakan layanan yang saling berhubungan termasukseluler, PCS dan fixed wireless (wireless local loop).

Teknologi CDMA IS-95A:

Standar seluler CDMA yang pertama IS-95A menggambarkan strukturwideband 1.25 MHz CDMA channel power control, call processing, hand-offs, dan teknik registrasi untuk sistem operasi.

Teknologi CDMA IS-95B:

2.5G TSB-74 menggambarkan interaksi antara IS-95A dan sistem CDMAPCS yang mendukung ANSI-J-STD-008. Banyak operator yang telah

mengkomersilkan sistem IS-95B 64 kbps packet-switched data, dalam halpelayanan suara.

CDMA2000 1xEV-DO mengirimkan data dengan kecepatan 2.4Mbpsdan mendukung aplikasi aplikasi seperti transfer MP3 dan videoconferencing.

CDMA2000 1xEV-DV menyediakan perpaduan suara dan layananmultimedia paket data berkecepatan tinggi hingga 3.09 Mbps secarbekesinambungan.

1xEV-DO dan 1xEV-DV kompatibel dengan CDMA2000 1X dancdmaOne.

Keunggulan CDMA


157/243

157

Keunggulan CDMA

Beda dengan GSM yang berdasarkan teknologi TDMA yanghanya mengacak suara yang dipancarkan, CDMA selainmengacak juga mentransmisikan suara dalam kode-kode sehinggasama sekali tidak bisa disadap.

CDMA menggunakan seluruh spektrum frekuensinya secara

sekaligus, sehingga kemungkinan gagal panggil (drop call) olehpenggunanya sangat minim.

Dalam layanan CDMA, frekuensi yang dipancarkan seluruhnyaini menjamin pembicaraan tidak terputus.

CDMA yang ada sekarang terbuka untuk bermigrasi tidak cumake G3 WCDMA. Generasi ketiga untuk CDMA terbuka luas, bisa

juga ke EDGE (enhance data rates for global evolution

) atauCDMA20003X, setelah melewati CDMA20

suara yang dipancarkan dan diterima oleh pelanggan CDMA jauhlebih jernih daripada GSM. 001X.

Keunggulan CDMA


158/243

158

Keunggulan CDMA Sebagai teknologi militer CDMA sangat tahan terhadapgangguan cuaca dan interferensi.

CDMA tidak dapat digandakan (dikloning) karena setiappelanggan diberikan kode yang berbeda (unik). Kode-kode inisangat sulit dilacak karena bersifat acak.

Daya pancarnya yang sangat rendah (1/100 GSM)

memungkinkan hand phone CDMA irit dalam mengonsumsibaterei, sehingga dapat beroperasi lebih lama untuk bicaramaupun stand by.

Kapasitas pelanggan per BTS CDMA dapat mencapai 6000 (10kali GSM). Hal ini disebabkan CDMA lebih irit dalampemakaian frekuensi

Besarnya kapasitas per BTS membuat biaya investasi yangdikeluarkan sangat rendah. Selain itu CDMA-2000 (1X)beroperasi pada spectrum frekuensi 800 MHz. Hal ini akanmembuat luas coverage BTS-nya jauh lebih besar dari GSM.

CDMA-2000 (1X) dapat me-ngirim data dengan kecepatanhingga 144 Kbps, sementara GSM 9,6 Kbps.

CDMA adalah teknologi spread spectrum dengan

Tidak diperlukan desain frekuensi, karena tiap cell

menggunakan frekuensi yang sama. Kapasitas, Kualitas dan Coverage area adalah tiga

parameter yang saling terkait dan menyesuaikan.

Summary


199/243

216

The next-generation network seamlessly blends the public

switched telephone network (PSTN) and the public switched

packet data network (PSPDN), creating a single multi-service

network.

Rather than large, centralized, proprietary switch

infrastructures, this next-generation architecture pushes

central-office (CO) functionality to the edge of the network.

The result is a distributed network infrastructure that leveragesnew, open technologies to reduce the cost of market entry

dramatically, increase flexibility, and accommodate both

circuit-switched voice and packet-switched data.

Aceess internet dengan wireless yang

menggunakan frekwensi 2.4 GHz Jarak terbatas dalam ruangan hanya sekitar 50 m

Banyak digunakan untuk Wireless LAN

Cocok untuk di HRB atau Gedung perkantoran

WIMAX atau Wireless Interoperability Microwave Access( Standard 802.16) :

Kemudahan dan kenyamanan akses intternet dariLaptopdi manapunberada, dengan trafik sd 70 Mbps ekivalen dengan ratusan ADSL

Akses Wimax lebih jauh bisa mencapai 50 Km. Dari BS

Frekwensi yang diusulkan 2-11 GHz dan 10-66 GHz Masalah redaman menjadi penting bila menggunakan frekwensi > 10 Ghz

Daya pancar juga menjadi masalah urgen di USA dibatasi s/d 1Watt dan di

Eropa s/d 100 mWatt
