A few years ago we looked into putting APs either on top, or just inside the Code Blue phones with external antennas – the problem we had was that the APs, with a NEMA rated box would be U-G-L-Y on top of the pole, and if inside the pole with external antennas the temperature, humidity and rainfall here in Houston would have them lasting not very long.

Personally I would stay away from wireless for emergency phones as you are bringing in more points of failure and not to mentioned unlicensed spectrum for emergencies. Plus you’ll need power to these points unless you want to rely on battery/solar…. Which again seems risky for emergencies. Our plan has been to either keep an MD110 unit in place (at least on the main campus) and/or use the cisco voice gateways or ATAs, and/or bring in PSTN’s directly from a provider. It will depend on cons/pros and costs once we start designing that part. Though I think Philippe’s comment below is pretty interesting(or awesome), get it cabled with cat 5/6 and install a wireless AP, for the phone either wired VOIP or an extra cable for an analogue service. -- Jason Cook The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
