It is really discouraging for us people who wants to use this new technology because someone else paid for that certain band allocation. Is this band (2.4Ghz) an "invention" of Meralco 'communications'(whatever) where we as common people cannot use it?
I still would want to know: 1. WHAT will be the effect of transmitting a 2.4Ghz signal 'breezing' through Meralco's transmission lines? Will say, 300mW or so, will it cause the entire area for a blackout? 2. If it will interefere with its communications, are they not using 'good' equipment that it can be easily disturbed by a minute signal? 3. ...if they want to collect fees with the use of this band? just airing, Jun [EMAIL PROTECTED] wrote: >>Orlando Andico: >>Ahh.
