Wireless phone system
Paging system - "Smart system" where everyone wears a transponder so the communications system knows where to page/ring you?
Fire/Life Safety systems - Detection and Warning
Entertainment - Internal Fiberoptic network to move large quantities of data - movies, etc? Cable TV analog
Satellite Entertainment TV/Radio
High Frequency Radio - 2-30MHz
Worldwide Coverage, very large antennas (30+ meters long, or longer?)
Possible 'Pirate' Radio Station(s)?
GMDSS System Global Maritime Distress Signal System, SOLAS requirement
VHF-FM Radio Marine Band 156-158 MHz SOLAS requirements to maintain a listening watch on distress frequencies
Coordinate small boat activities around SeaStead, each small boat equipped with one of these too.
Relatively small radios, low power (~25w ERP), small antennas (2 meters or less in length, max. Handhelds ~8" long)
VHF-AM Radio Aircraft Band 118-136MHz
Coordinating air traffic inbound and outbound.
Several frequencies: Departure/Approach, Tower (landing), Ground (ground movement), coordination frequencies
Air Traffic Control radar
Tactical Radios - Trunked 800 MHz systems? Used for:
Firefighting / EMS
Need to investigate frequency propagation through structures.
Other radios - Ability to monitor/speak on military frequencies, ie
30-70 MHz FM (Military Tactical Net);
220-400 MHz AM (Military aviation band), etc?
"Company" radios for SeaStead operations, similar to business-band frequencies (VHF-FM High at 150MHz or UHF-FM at 450-470MHz and/or 800 MHz trunked system. Will probably require robust encryption.
