Choosing the base stations

Suitability of a location is primarily determined by ability to access the areas expected to have the highest levels and good line of sight to the antennas.

Sites were selected in order to cover, as well as possible, all network operators, technologies, geography and type of installations. Other factors to be taken into account included the level of public concern, concentration of base stations in close proximity, or other special circumstances that may provide cause for community concern.

Initially, local councils were invited to nominate base stations for inclusion in this survey. An article appeared in the Australian Local Government Association newsletter of 15 September 2006 calling for nominations. Eight base stations were nominated by local councils. Further sites were suggested by ARPANSA and members of the EMERG. A shortlist of 23 suitable sites was submitted to EMERG for consideration.

The following table indicates the network operators and technologies covered by the present sample of base station sites.

Operator Technology
CDMA GSM900 GSM1800 UMTS All
3GIS n/a(1) n/a(1) n/a(1) 10 10
Optus n/a(2) 9 2 12 23
Telstra 4(4) 10 2 15(3) 31
Vodafone n/a(2) 6 2 11 19
All 4 25 6 48 83

 

Notes:

  1. 3GIS only operate a UMTS service
  2. Neither Optus or Vodafone operate a CDMA service
  3. Telstra’s UMTS service operates in the CDMA800 frequency band and is also referred to as WCDMA850
  4. Since this survey began, Telstra has switched off its CDMA service
