Hi guys, We’re reviewing one of our links that is using RocketM365 radio and a RD-3G-26 in each end. The link is using 5MHz channel width.
Here is the question: Checking the FCC regulation part 90.1321 I found that the limitation of the EIRP is defined as follow: § 90.1321 Power and antenna limits. (a) Base and fixed stations are limited to 25 watts/25 MHz equivalent isotropically radiated power (EIRP). In any event, the peak EIRP power density shall not exceed 1 Watt in any one-megahertz slice of spectrum. What I understand from this text is that for instance, if the link is using a 25 MHz channel then the maximum EIRP is 25 W, and if the link has 10 MHz channel width then the maximum EIRP is 10 W. If I’m getting it right, our link can still increase the bandwidth changing the channel width to 10 or 25 MHz and still comply with the maximum EIRP establish by the regulation. I’m interpreting the limitation correctly? Thanks, Eduardo Mejia Webjogger Internet Services www.webjogger.net
