Conclusion

California doesn’t need any more telecom-focused state bills, such as AB-965 or AB-1065. To close the Wireless digital divide, the CA Attorney General just needs to enforce the laws on the books for all currently unserved areas in California because FCC license terms require that providers serve the areas covered by the licenses. The FCC licenses currently in place require wireless carriers to ensure that all major roadways in these areas have wireless telecommunications service. In short, no more expensive, taxpayer-funded carrots are needed — just one effective stick.

Current FCC data proves that AT&T, Dish, T-Mobile and Verizon all have sufficient FCC wireless licenses in every California county to provide wireless signal strength — as measured by Received Signal Strength Indicator (RSSI) levels between -125 and -85 dBm — for wireless telecommunications service (the ability to make outdoor wireless phone calls, along major roadways). If there any areas with a significant gap in wireless telecommunications service in 2023, California’s Attorney General can enforce the terms of the FCC license to compel wireless carriers to install sufficient infrastructure in order to close that significant gap in wireless telecommunications service.

Legend: Commercial Wireless Spectrum Categories for Tables That Follow

Low-Band = 663–2,200 MHz — includes T-Mobile 5G-600 MHz and earlier 3G/4G bands
Mid-Band = 2,305–3,980 MHz — includes recently-auctioned 5G-Citizen Band Radio Spectrum (CBRS)
High-Band = 24,250–48,200 MHz — near-millimeter and millimeter wave spectrum, which is no longer being deployed, other than in select entertainment venues and a very few urban areas
