Question: What data must be submitted to show out-of-band compliance for emission limitations using the alternative out-of-band emission limits for Parts 22 and 24 Devices?

Answer:

Submitted data using the alternative out-of band limits of 47 CFR 22.917(c) and 24.238(c) only requires measuring emissions outside of the service band for cellular and broadband PCS service. Showing compliance to out-of-block emissions within the service band is not required (i.e. out-of-band emissions in Block B from equipment operating in Block A). However, equipment certified in this manner requires that the licensee must have the documented private contractual arrangements specified in 47 CFR 22.917(c) and 24.238(c) for all affected licensees and applicants. Submitted data will require a minimum set of data that contains 2 plots, one plot is for the lower edge of the service band and the other plot is for the upper edge of the service band. Separate sets of plots are required for mobile and base equipment, cellular and Broadband PCS equipment and for each modulation type.
