Cellular Coverage:

• There are several cellular sites located within Yosemite Park boundaries and some just outside the park.  These sites serve  developed areas of the park and their signals may be accessible from points far away from these locations, but that coverage can be variable and unreliable.
  
  
• Variations in topography and elevation affect cellular coverage in the park significantly.  In developed areas, wi-fi is also available but it is provided by private concessionaires and not by the Park Service.
  
  
• The coverage area shown is approximate. There can be addtional cell sites within park boundaries that do not show in public records. Most park cellular coverage has not yet been field checked.
  
  
• Verizon Wireless has requested to reconstruct the existing wireless telecommunications site in Yosemite Valley. The existing site is located adjacent to the electrical substation and is made up of several equipment cabinets and a 65' wooden monopole. The existing site is 20 years old and has been modified several times. Currently AT&T Mobility and Verizon Wireless have facilities at the existing site. The reconstructed site would add a third telecommunications carrier, T-Mobile.
  
  This project calls for the construction of a new steel monopole, 100' in height, and a reconstructed and enlarged communications equipment area. The site is to be served by fiber optic cable to the existing communications conduit recently built under the park communication data network project. This site was originally approved in 2015.
