But at what cost for scarce 60GHz gear and how far are we trying to backhaul? "One drawback of 60-GHz is the oxygen absorption (~10dB/km at sea level) which begins to play a role at ranges greater than 100m. Additionally, rainfall adds additional attenuation (another ~5dB/km for region K at rain rate of 12mm/hr). High-gain antennas certainly help to overcome these atmospheric effects." http://domino.watson.ibm.com/comm/research_projects.nsf/pages/mmwave.apps.html I can't imagine the power consumption is very low either but I've not yet been able to find any data on that subject. Cool idea but there may be more feasible options. -Gary --~--~---------~--~----~------------~-------~--~----~ The Personal Telco Project - http://www.personaltelco.net/ Donate to PTP: http://www.personaltelco.net/donate Archives: http://news.gmane.org/gmane.network.wireless.portland.general/ Etiquette: http://www.personaltelco.net/index.cgi/MailingListEtiquette List information: http://lists.personaltelco.net To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] -~----------~----~----~----~------~----~------~--~---
