Do not think it is 1xRTT since this is in one of the SAR docs.

The equipment, KWC model # 2135, is for mobile station cellular and PCS system use. The 2135 is in full compliance with all parts of EIA/TIA/IS-98-B Mobile Station-Land Station Compatibility Specification, issue July 1998, and also in full compliance with all parts of ANSI J-STD-018, Recommended Minimum Performance Requirements for 1.8 to 2 GHz Code Division Multiple Access (CDMA) Personal Stations, issue July 1996.

Also, has several pages from old spec.

The CDMA mode is described in the following pages from the TIA/EIA /IS-95B Standard. The justification for the CDMA bandwidth of 1.25 MHz is that the chip rate is 1.2288 MHz (see page 6-35 of IS-95B). The 1.25MHz is measured at the
3dB down bandwidth. Channel spacing is normally set at this 1.25 MHz. In addition the reference baseband filtering requirements are shown on page 6-60 of IS95B. The Z-transform filter coefficient for the recommended baseband filter are shown on page 6-61, and also yield a “necessary bandwidth” of 1.25 MHz based on optimal detection and channel capacity theory.

You are more familiar with these specs than I, what do you think. Wish the parts list and/or schematics were there.

The Nokia 6-series has this nice removable "name plate",
any bundled operator can snap in their own, and the
user can snip it off, if the operator want to open the box.

It is funny how all these things disappear when markets
are unbundled, get the SIM-card from the operator
and the handset from whatever store, mail order
whatever gives the best deal with the original box
intact.

If one is tired of the operator, get a new number
and a SIM card, if it is the phone, get another one,
same or different store.

And some day the bundle-dependent operators will have
to implement fixed, shared IP adresses both for my
refrigator and me.

I don't switch the name of my street every time I
cancle or order an old or new newspaper..
