What is ADS-B?
ADS-B (Automatic Dependent Surveillance – Broadcast) in simple terms is a small black box that can be installed in an aircraft. It sends the location and the altitude of the aircraft to other aircraft and ground stations.
Note that the US Federal Aviation Administration (FAA) actually plans to use two types of datalinks in its ADS-B implementation. One is for general aviation aircraft and another for airline aircraft. The GA aircraft will be equipped with Universal Access Transceiver equipment (in the 900 MHz band) and airline aircraft will use Mode S transponders on 1090 MHz.
There is a proposal in Australia for ADS-B, however it will not use the Universal Access Tranceiver as was proposed in the USA. Sweden has also gone ahead with an ADS-B system that is different to both the USA, and that proposed in Australia.
The FAA plans to install base stations which have both 900 MHz and 1000 MHz transceivers, which are interconnected. Each transceiver will transmit information from the other - so airline aircraft will be able to know the position of general aviation aircraft and vice versa.

Dick Smith answers PPRuNe on ADS-B
I’ve always supported ADS-B – I just don’t support Australian general aviation being guinea pigs for a system which is being rushed in to maximise profits and has not been looked at properly. For a start, privacy issues have not been properly looked at – nor have security issues.

ADS-B Misleading Information
Recently the Civil Aviation Safety Authority has produced a magnificent colour document on ADS-B. The brochure shows all the fantastic gizmos, including ADS-B ‘in’ displays, such as a CDTI (Cockpit Display of Traffic Information) and also the small hand-held CDTI. Unfortunately none of these units actually exist at a reasonable price ...

Airservices are making a number of claims in relation to ADS-B for general aviation aircraft. Originally it was understood that an ADS-B ‘out’ transponder would cost about $8,000 and still need to be connected to a separate GPS receiver. The latest cost that is being estimated is about $12,000 ...
