[ns] Cellular Digital Packet Data

[Ranjay John Cherian <ranjay@protocol.ece.iisc.ernet.in>]

Hi all,
	I would like to know whether a "Cellular Digital Packet Data
(CDPD)" environment can be simulated using ns. If this feature has not
been incorporated in ns, how do I proceed with modifying the ns code in
this regard. 
	
	Thanks in Advance,
Regards,
Ranjay
