Recommendations for Removal of AMPS in 3GPP2 Specifications

July, 2010

2

Overview

• Background– AMPS network shut down in 2008, allowing removal of special AMPS blocker requirements

and harmonization of 3GPP and 3GPP2 specifications.

• 3GPP2 AMPS blocker protection/requirements– STD (Single Tone Desense)

• CW blockers at 900kHz (Band 0) or 1.25MHz offset

– In-band IM

• CW blockers at 900kHz/1.7MHz (Band 0) or 1.25MHz/2.05MHz offset

• Modifications to C.S0011 (IS98) and C.S0033 (IS866) specifications– Details in following slides

– BC3 and BC6 specs will not be modified

• Eliminate existing Single Tone Desense requirement (C.S0011 3.5.2, C.S0033 3.3.2)

• Replace with Narrow Band Blocking similar to 3GPP and apply to all bands (except BC3 and BC6)

• Modify existing intermodulation requirement (C.S0011 3.5.3, C.S0033 3.3.3)

• Replace with close-in and far-out IM requirements for all bands (except BC3 and BC6)

Adjacent Channel

• Existing Adjacent Channel Selectivity requirement (C.S0011 3.5.4, C.S0033 3.3.4)
