5. WiFi BOOSTER ANTENNAS
WiFi is a very flexible technology in that the range can be significantly increased by the use of directional antennas and wireless repeaters. The basic WiFi access point has limited RF power output and does not represent any hazards to users in the near vicinity.
In most instances The RF output is essentially transmitted omni directionally (over the full 360 degrees around the antenna). Nevertheless, directional antennas guide the RF energy into a narrower beam and can thus concentrate that energy. Although the level of energy is generally low it would be undesirable both for health and safety and radio link performance to "aim” these directional antennas in areas which are routinely occupied.
The Ministry of Health, Ministry for the Environment and Ministry of Economic Development’s Spectrum Management Group have prepared “National Guidelines for managing the effects of radio frequency transmitters”. This document supports research carried out by the International Commission for Non-Ionising Radiation Protection, which was used in the production of the New Zealand Standard NZS 2772.1: 1999 “RF Fields”.
The National Guidelines referred to above give a lot of information on the subject of RF energy, along with some useful tips on minimising exposure. The main points for users of WiFi booster antennas are to site them where there is the least exposure to any people in the vicinity, choosing a product that avoids unnecessary splllage of RF and keeping RF power to the minimum needed for the range required.

6. TELECOMMUNICATIONS RELAY SERVICE
The first Telepermits have now been granted for textphones or “TTY’s” ready for the introduction of the Telecommunications Relay Service on 15 November. We have opened a new PTC 215-series for these products, a range of which are expected to be available by the time the service starts.
A CPE testing programme is proposed as soon as the TRS Call Centre equipment has been commissioned.
In view of the tight timing, it is recommended that any suppliers wishing to gain Telepermits for TRS CPE, and have their products ready by start date, should arrange testing to PTC200 and submit their applications as soon as possible.
