RE: [DNA] Considerations for DNA Schemes with multipleInterfaceandLayer 2 Technologies

[Brijesh Kumar <kumarb@research.panasonic.com>]

Yong-Geun;

Like JinHyeock and Greg, I am too curious why CDMA soft handoff should
impact
the DNA scheme specially since CDMA provides make before break ability.

Since with CDMA, it is possible to combine the data received from two
or more different sites to ease the transition from one to the other,
I am unable to see why this will have any DNA issues at all.

Can you please elaborate a little bit more clearly.

Cheers,
