interference of multi mode terminal equipment.

This standard is applicable to all multi mode terminals, including multi mode

single-standby terminals and multi mode multi-standby terminals. Such as. GSM/CDMA

(cdma2000 1x) dual mode terminal, dual GSM terminal, GSM/WLAN terminal and CDMA

(cdma2000 1x)/ WLAN terminal.

2 according to the requirements of YD/T 1484, and select the high, middle and low signal

channels and launch Module 2 with the maximum power.

6) EUT location and test antenna polarization shall be adjusted according to the

reference location and reference polarization determined by step 3.

7) It shall rerun step 4). And record the EIS of each channel.

8) Difference between measurement results of step 7 and step 4 on each signal

channels shall not be more than 5dB.

9) It shall establish connection on CDMA (cdma2000 lx) 2GHz frequency band for

Module 2.Repeat measurements in step 5) ~step 8). And the difference of measurement

results shall not be more than [TBD] dB.

10) It shall establish connection on GSM1800 for Module 1.Repeat measurements in

step 1)-step 9). And the requirements of step 8 shall not be more than 5dB and not more

than [TBD] dB in step 9.

11) As specified in Section 4.2, if Module 1 supports multiple applications and scenarios,

measurement shall be conducted under multiple applications and scenarios according to

step 1)- step 10).

6) BER on all adjacent signal channels closest to the signal channels (as shown in

Figure 1) for Module 1 shall be measured under the forward power determined by step 5).

Measurement result of BER shall not exceed 1.2%.

7) The BER measurement results in all the channels of Module 1 shall be recorded.

8) As specified in Section 4.2, if Module 1 supports multi-band frequency, multiple

applications and scenarios, measurement shall be conducted under multi-band frequency,

multiple applications and scenarios according to step 1)~step 7).

2 shall be measured according to the requirements of YD/T 2193, while Module 1 is under

the idle mode.

2) The location and polarization of the optimum sensitivity point on high, middle and low

signal channels of Module 2 of EUT as well as the measurement results of optimum

sensitivity on that point shall be recorded.

3) The connection between Module 1 and base station simulator (connection by

selection of high, middle and low signal channels on different frequency bands

respectively) shall be established according to the requirements of YD/T 1978 and Module

1 is launched with the maximum power.

4) The position and polarization of EUT shall be adjusted to make it the same with the

recording results of step 2).

5) The output power (i.e. forward power) of base station simulator of Module 2 shall be

adjusted to the optimum sensitivity +5dB recorded in step 2) (As shown in Figure 1

6) The packet error rate on all adjacent signal channels closest to the signal channels

(as shown in Figure 1) for Module 1 shall be measured under the forward power

determined by step 5). Measurement result of packet error rate shall not exceed 10%.

7) The measurement results of packet error rate in all the channels of Module 2 shall be

recorded.

8) If Module 2 supports 5GHz frequency band, corresponding measurement shall be

conducted for 5GHz frequency band according to the methods mentioned above with the

module as Module 2.
