Waivers will allow retuning older U-NII-3 band systems to operate in U-NII-1.
The new U-NII rules, which take effect June 2, increase the power limits for the U-NII-1 band (5.15-5.25 GHz) and allow outdoor operation. Devices certified for the higher-powered U-NII-3 band (5.725-5.825 GHz) can be retuned for use in U-NII-1, but older systems may not comply with the new rules. Users or providers of those older systems have 30 days – until July 2 – to apply for waivers to allow their operation in U-NII-1. The FCC expects to quickly approve any such requests that seek to operate within the U-NII-1 band with up to 250 mW of conducted power and a PSD of 11 dBm/MHz with a 6 dBi gain antenna. This does not automatically rule out requests for higher power that come within the old rules for U-NII-3 (i.e., the ones that were in effect before June 2) or under the former version of Section 15.247, but the FCC may take longer to consider these.
If the above makes no sense to you, no need to worry – this post probably doesn’t affect you. Just ignore it.
