SMAG Consultation on Wireless Home Area Networks

Background

On Thursday 21 September 2000, SMAG held a Consultation Meeting on Wireless Home Area Networks. There were 8 presentations covering market requirements, spectrum allocations, regulatory matters and health issues. The event was attended by some 50 delegates from the telecommunications, consumer electronics and regulatory sectors.

here was lively debate and a number of conclusions or recommendations were reached.

Conclusions

1. Wireless home area networks are set to become a major market for equipment manufacturers. Product is already starting to appear using the IEEE802.11 standard.

2. It is essential to work towards a harmonised global standard. There are several candidates, but attention is focusing on IEEE802.11 and Hiperlan2.

3. The potential for congestion in certain locations is already being seen in the use of the 2.4GHz ISM frequency band. Bluetooth devices will increase this. The RA should decide on action regarding the recommendations in the report from Aegis regarding congestion in this band.

4. The legitimacy of use of the 2.4GHz band by Internet Service Providers was questioned. Regulatory issues associated with the possibility of Bluetooth devices communicating directly with public local nodes to create an alternative mobile communications network need to be addressed.

5. Wireless home area networks should be covered by as light a regulatory structure as possible.

6. Wireless home area networks could be important in facilitating and speeding the transition from analogue broadcasting to digital broadcasting.

7. Adaptive r.f. power control should be an important part of system design, thereby minimising the overall level of r.f. energy emitted.

8. Note should be taken of the recommendations in the Stewart Report on Health Effects in the Use of Mobile Phones.

9. Future focus must be in two areas:

Intelligent and early development of the 5GHz band, ensuring international compatibility and close liaison with the 5GHz industry consultation group.

Consideration of new technology such as Ultra-wideband (UWB) systems, their standardisation and licensing.
