1.GSM/GPRS/EGPRS Test Strategy

1. Testing GSM only, do not test GPRS/EGPRS

- There are many changes in physical layers in GPRS.

( e.g. PLL/LO timing, 2 uplink PvT testing, Block Error Rate…..)

2. Testing GSM & GPRS & EGPRS in 2 separate testers

- Waste of handling time, power on/off & camping time,…….

- GSM & EGPRS testings are very similar.

3. Combination GSM & EGPRS testing together

NO GPRS testing required

- Saving the overall testing time

- Testing the switching between GSM (Voice) & EGPRS (data)

- EGPRS will cover GPRS testing.

GSM/EDGE Test Strategy

Different Testing Strategies

1. GSM (Major test) + EGPRS (Minor)

2. EGPRS (Major test) + GSM (minor)

3. GSM (50%) + EGPRS (50%)

Different Testing conditions

New GPRS testing items

- Slot Configurations: 1x1, 2x1,3x1, 4x1, 2x2, 3x2

- Modulation Coding Scheme: MCS1-4 (GMSK)

- MCS5-9 (8PSK)

- Uplink & Downlink MCS BLER testing.
