Answer to question 1 is: Depends on the frequency used. The two
proposed specs are using different frequency bands. The 802.20 uses
lower frequencies which should have less impact by rain, fog, snow
etc.
Answer to question 2 is: Yes for distance objects and maybe for
weather see answer to question 1.
The specs are designed for different applications. The 802.20 is
designed for mobile operation at speeds up to 150 kph and bandwidth of
around 1 mbit. The 802.16 is designed for fixed sites at much higher
bandwidths but not optimized for a moving target.
As far as growth my opinion is that the 802.16 spec is redundant to
the 802.11 a/b/g spec. the current specs can do most if not all of the
functions of the 802.16 The only improvemnt that 802.16 offers is full
duplex and QOS. There are already some manufactures that have
implemented the QOS functions.
802.20 is likely to be implemented by users such as public safety and
utilities for licensed data networks. The equipment will likely be
significantly more expensive then 802.11 products and may operate on
licensed channels.
