Slide 15: Example Capacities
* GSM with AMR, 5/15 BCCH (GSM) Frequency Reuse and 1:1 non-BCCH Frequency Hopping
One
Way
MHz Technology Erlangs/Sector
5 TDMA, 5/15 23
5 GSM AMR, 5/15 BCCH + 1:1 FH non-BCCH 36 to 48
10 TDMA, 5/15 54
10 GSM AMR, 5/15 BCCH + 1:1 FH non-BCCH 86 to 123
* Initially (Phase 2) AWS is planning to apply EDGE in 10 MHz of 1900 MHz spectrum (5 Receive and 5 Transmit).
* In their 3rd Phase AWS will add 10 MHz additional in 850 MHz spectrum.

Slide 4: Data Rates for Applications
* User experience depends on cell engineering, user location, sector load, available spectrum, terminal capability, etc.
* Data rate of 128 kbps is sufficient for most initial 3G applications
Requires
- Voice 8 kbps to 16 kbps
- Messaging & Transactional 12 kbps to 30 kbps
Infoservices
- Video Telephony 16 kbps to 64 kbps
- WWW browsing 32 kbps to 64 kbps
Intranet access
Downloading
- Video & Audio Streaming 30 kbps to 128 kbps

Slide 5: Data Speed Comparison (Loaded Network)
Average Average
Peak Peak PC Streaming

Speed Speed Speed Speed
GPRS 115 kbps 470 kbps 20-30 kbps 10-20 kbps
EDGE 470 kbps 237 kbps 80-130 kbps 20-40 kbps
WCDMA 2 mbps 2 mbps 200-300 kbps to 384 kbps
1xRTT-0 153 kbps 153 kbps 40-60 kbps ~ 64 kbps
1xRTT-A 53 kbps 307 kbps 70-130 kbps * ???
1xEV-DO 2.4 mbps 2.4 mbps 120-300 kbps 50-100 kbps
Note: AWS did not include 1xRTT Release A. I added it with a WAG at Average Speeds
