We establish and maintain RF safety compliance at mobile network sites.
Modern mobile communication networks typically consist of thousands of transmitters and are not static in design or layout. A process is therefore required for establishing RF safety compliance at all base transmitter stations (BTS) in a network.
This process should be designed to cater for revisiting and management of sites in the network when a site is modified to a new configuration of technology or antennas. The process can include very basic checks for easily assessable sites such as free standing masts. More comprehensive assessments that might include measurements or computer simulations are required at more complex sites such as rooftops with shared RF services.
Network providers maintain large databases of information describing the physical location and transmission entities, as required for compliance assessment. Along with tried and tested efficient protocols for the establishment and maintenance of RF safety compliance in a network, Alphawave Mobile Network Services has the know-how and tools to integrate these databases with information gathered by surveying teams at BTS sites.
Measures required for compliance
The EMF guidelines most widely accepted in industry for the assessment of compliance are set and maintained by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The ICNIRP guidelines specify which levels of exposure are safe for humans to operate in and are referred to by the World Health Organisation (WHO).
Compliance with EMF guidelines can usually be established by satisfying three requirements.
- Identification of areas of non-compliance through generic rules, computer simulation or RF measurements.
- Implementation of reasonable and practicable administrative controls for areas of non-compliance.
- Monitoring and documentation of compliance status and control measures.
Why EMF Compliance?
It is important for a mobile communications network provider to maintain compliance with established international EMF health and safety guidelines. Good corporate governance as well as OH&S legislation requires that all employees work in a safe environment. BTS sites are not a huge health risk due to the relatively low power transmitters typically used in a network.
Nonetheless, it is relatively easy to ensure and document full compliance in a network if established tools are employed.

The basic course is customised to include details of, amongst others, the operator-specific site access arrangements and RF signage.
A medical screening is also included in the RF Awareness training courses before staff may be classified as RF workers. Courses are presented by staff with the relevant qualifications in electromagnetic engineering and with specific industry experience in human exposure to RF. More advanced courses are also available for people requiring a more detailed technical understanding of EMF exposure.
