Question of the Day: What's the most interesting small town you've visited in South Africa?
Telecommunications spectrum
- Thread starter ic
- Start date
IMO, what would be great is a visualisation of the spectrum allocations, i.e. starting at 0 and then go up to whatever is the highest allocation to date. Maybe on a log scale, since it goes into gigahertz at the moment.
People will then be able to understand where radio (FM &AM) fit in, cell phone technology, blue tooth, walkie talkies, wifi, wimax, existing microwave communications, etc. Or maybe someone else has already done it somewhere?

It's been years' since I completed my radio licence (close on 15 in fact) these things very much exist they are known as bandplans and include the frequencies, purpose (aircraft, telemetry, broadcast, amateur, etc...) and the modes of communication permitted (AM / FM / SSB / Digital, etc...).
ICASA has them available starting at the bottom end of the spectrum (longwave) used in submarines through around 70GHz which is primarily for experimentation as it's not much good elsewhere.
The most occupied sections are through to around 3500MHz (3.5GHz) with higher use mainly for satellite communications.
below that, huge parts are used for broadcast (AM/FM, UHF/VHF TV), Cellphones 800/900/1800/1900 and 2100MHz
Plenty is allocated to Amatuer radio, some for unlicenced communication.
There are several reason ICASA can't just hand the stuff out willy nilly, one being that there are international standards they have to hold to another being that this space is very very limited and just handing it over to private enterprise (however well meaning it may be now) may well result in problems at a future date when it's needed for something else (like the medical industry or aircraft).
The radio amatuers are already up in arms about the interference GTS is creating with the broadband over powerline. visit www.sarl.org.za
