group asked the FCC to relax the OOBE limits for mobile digital stations in Section 27.53(m)(4) of its rules from 43+10 log (P) dB to 40+10 log (P) dB at the channel edges and to impose a 43+10 log (P) dB attenuation factor beyond 5MHz from the channel edges, and a 55+10 log (P) dB attenuation factor at “X” MHz from the channel edges where “X” is the greater of 6 MHz and the actual channel bandwidth. WCA also asked the FCC to allow a resolution bandwidth of 2 percent for mobile digital stations in Section 27.53(m)(6). “Amending the OOBE limits in the 2.5 GHz band as requested is necessary to realize the full benefits of 4G technologies and better align the Commission’s rules with the approach of the global 3rd Generation Partnership Project (3GPP) and future WiMAX standards applicable to the 2.5 GHz band,” WCA said in the petition. “Providing for operation of wider channel bandwidths will promote efficient use of the spectrum and help achieve the goals of the National Broadband Plan for mobile broadband."
