couple things

1.)

power booster would be designed native to particular phone

designed for particular freq band

cradle or docking station for xda (charges with signal rx - antenna on top of car wired into cradle)

33cm band is old analog cell operating band. You might have interruptions sound like conversation(hi-freq noise w/multi-tones)

23cm band(1240-1300Mhz), 13cm 2350-2450Mhz(right in middle of celll phone authourization band - most of GSMs here)

GSM requires carrier-authorization (freq band) 900-928Mhz which is near cell phone range.

Microwaves may have skin heating effect. Questions of safety of being in close contact with xdas and cell phone towers known to cause cancer. Antennas in microwave range are extremely small. Could make collinear to give multiple gains. U could get pretty hi gain wi fi antenna in 900Mh~2 ghz range. Couplers(passive) could be used with antennas in cars

Many collinear high gain antennas would multiply 10000-20000x the power with a power amp. external antenna would give 20x-30x range. mounted atop vehicle or house would give far better line of sight both tx and rx. would easily recover loss from passive coupling on back side of radio. ctrl ops would have to provide very precise measurements on operation in freq and band. legal to do if authorized and operating in legal bands of FCC (here in usa...every country would have near equivalent comm regulators)

2.)

d-Star a protocol to internconnect cells into digital repeater systems. Ppl talk 100-150 miles apart with its usage. Transfer video, audio, or data. With packet radio u could transmit text thru pda entirely thru ham radio. It may go partially thru both ham and cell towers to hit say australia.

possible to use ham over ip software to find repaters' url and will be encapsulated as traffic.(ax.25 protocol used in amateur radio...internet affected by similar ix.25 protocol) GSM refers to type of modulation used to modulate signal. once it gets back to the inernet its born as packets of info ie voip graphic images ascii whatever (but no porn!)

links would be limited for instance if link transmitted at 300 baud it would take forever. but text for example ascii short and sweet would easily be transmitted in 12-15 modes psk 31, packet radio, paktor, amtor (amateur radio version of sitor), baudot. ascii is a recognized easily. all is encapsulated.

baudot is 5bit instead of 8bit. still used today in deaf phones with 5bit baudot code. makes it easy to use as a terminal into a ham radio. easy to talk to teletype operators over world. alot of times host will translate over internet with known repeater-ip address. connect to digipeater over ham(or cell?) and internet. Lots of mailbox like systems. almost like an email server.
