AMPS (Advanced Mobile Phone Service)
- Analog voice service - No data service
2G wireless
CDMA (Code Division Multiple Access) TDMA (Time
Division Multiple Access) GSM (Global System for
Mobile Communications) PDC (Personal Digital
Cellular)
- Digital voice service - 9.6K to 14.4K
bit/sec. - CDMA, TDMA and PDC offer one-way
data transmissions only - Enhanced calling
features like caller ID - No always-on data
connection
3G wireless
W-CDMA (Wide-band Code Division Multiple
Access) CDMA-2000
- Superior voice quality - Up to 2M bit/sec. -
always-on data - Broadband data services like
video multimedia - Enhanced roaming

• 1. Capability to support circuit and packet data
  at high bit rates
• 144 kilobits/second or higher in high mobility
  (vehicular) traffic
• 384 kilobits/second for pedestrian traffic
• 2 Megabits/second or higher for indoor traffic
• 2. Interoperability and roaming
• 3. Common billing/user profiles
• Sharing of usage/rate information between service
  providers
• Standardized call detail recording
• Standardized user profiles
• 4. Capability to determine geographic position of
  mobiles and report it to both the network and the
  mobile terminal
• 5. Support of multimedia services/capabilities
• Fixed and variable rate bit traffic Bandwidth on
  demand

Problems

• Tanggapan market .perlukah layanan 3G ?
• Data trafik adalah campuran antara dedicated data
  (voice) dan non dedicated data
• QoS masing-masing layanan berbeda

Lalu bagaimana..?

Problems

• Tanggapan market

Perlu jaringan transisi untuk membiasakan pasar
dengan layanan 3G

Problems

• Data trafik adalah campuran antara dedicated data
  (voice) dan non dedicated data

Perlu dipisahkan antara trafik suara (dedicated
channel) dengan trafik data

Problems

• QoS masing-masing layanan berbeda

Pemberian prioritas yang berbeda tergantung
data yang dilewatkan trafik suara, atau data,
atau suara yang dijadikan data
Suara (dedicated channel)
Probabilitas Blocking

Throghput, delay
Data (non dedicated channel)

Throughput untuk VoIP secara independentharus
lebih besar dari throughput untuk data yang lain
( internet, fax, dsb )karena memerlukan delay

Diskusi
Transmisi

• Unjuk kerja transmisi pita lebar, indoor dan
  outdoor
• Perencanaan transmisi WCDMA ( kapasitas,
  efisiensi spektrum, perilaku sel terhadap
  interferensi (cell breathing), analisis handoff,
  dsb
• Perbaikan sistem (smart antenna, software radio)
  dan unjuk kerjanya
• dll

Jaringan

• Interkoneksi antar jaringan dan topologi
• Billing, roaming
• Protokol dan signalling
• Dll
