I thought they were using the airphone ( satellite phones that were in
the planes which cost a small fortune.
Question for Mark, anyword on what cell technologies and freq it will
support. GSM uses 4 different bands depending where you are and what
your provider is. wouldnt the 800 and 850 bands cause problems with the
plane. Even with the alto bridge creating a mini tower to make the
cells go into lowe power mode as it thinks it is sitting right on a
tower, isnt it still add up if you have half the plane dialing on there
cells.
What kind of simulated load was done during the test. the FCC press
reelase did not say.
Other than the logical CDMA, are they going to make it compatible with
TDMA ( which is not used too much these days but was the basis of gsm)
also would they even waste the money on motorollas iden technology even
though the largest provider in the world is droping it. ( nextel
surprising is the largest user of iden in the world) But is Honeywell
going to do any information press release about alto bridge soon.
