47 CFR FCC Part 30 Certification Testing of Upper Microwave Services
Part 30 of the CFR FCC test standard determines requirements, applications, and procedures for the testing of upper microwave services. As a leader in RF regulatory compliance testing, Keystone Compliance recognizes the requirements needed for wireless radio manufacturers. Meeting the ETSI, FCC, and other wireless testing specifications can be challenging. Not only do we understand the challenges, but we help guide companies through the process.
Keystone’s radio testing engineers streamline the process and assist companies to achieve the compliance they require. We tailor each test plan to individual customer needs minimizing unnecessary costs and over-testing. Our proven process helps avoid product launch delays by inviting our clients to review draft reports before final certification. Additionally, we are in constant communication throughout the entire test process.

Summary of Upper Microwave Service Testing
As of December 2016, Local Multipoint Distribution Service licenses for the 27.5 – 28.35 GHz and 38.6 – 40 GHz band under Part 101 have been reassigned to the Upper Microwave Flexible Use Service. Services in bands other than mentioned above will remain conducted by part 101 of the 47 CFR FCC standard.
An initial authorization includes manufacturers submitting a single application for all markets won and frequency blocks desired. Initial authorizations will have a term not to exceed ten years from the date of initial issuance or renewal.
Point-to-point station: This transmits a signal from a fixed transmitter location to a fixed receive location.
Point-to-Multipoint User Station: A fixed radio station lies within the coverage area of a Point-to-Multipoint Hub station. The station uses a directional antenna to receive one-way communications. It can also provide two-way communications with a fixed Point-to-Multipoint Hub Station.
Scope of Wireless Part 30 Microwave Service Testing
Licensees of this service must make a buildout showing their renewal applications. Licensees must also show proof of reliable signal coverage and service for at least 40% of the local population. Showings that rely on a combination of multiple types of service are evaluated on a case-by-case basis.
Other criteria and performance requirements within this wireless standard can be clarified by our expert wireless lab test engineers. However, failure to meet the FCC requirements will result in an automatic cancellation of the license.
Manufacturers are subject to radiofrequency exposure requirements. Applications for mobile or portable devices must contain a statement confirming compliance with these requirements.
Intentional Radiator Service Testing Conditions
For fixed and base stations operating in connection with mobile systems, the average powerline is limited to a specific equivalent isotropically radiated power density defined in the standard. For mobile stations, the average power of the sum of all antenna elements is specifically limited. The limitations are to a maximum EIRP of +43 dBm. For transportable stations, it is limited to a maximum EIRP of +55 dBm.
Emission limits outside a licensee’s frequency block must be -13 dBm/MHz or lower. When measuring emission limits, the nominal carrier frequency is adjusted as close to block edges as the design permits. The measurements of emission power can be expressed in peak or average values.
Before operating a fixed point-to-point transmitting facility, frequency coordination must be completed.
Keystone Provides Expert Upper Microwave Service Compliance Testing
In addition to intentional radiator testing, Keystone has a full scope of expertise including pre-approved radio modules, and licensed radios. Our team strives to give our customers more time and energy on product development instead of testing.
