Google WiFi is a municipal wireless network deployed in Mountain View, California. It is entirely funded by Google and installed primarily on Mountain View lightposts. Google had committed to keeping the service free until 2010. The service was shut down by Google on May 3, 2014 at their Mountain View base, and are now working to provide public outdoor WiFi. 
As of 2009, Google uses over 500 Tropos Networks MetroMesh routers acting as access points mounted primarily on utility poles providing usable signal and broadband internet access to over 95% of the city's area of 12 square miles (31 km2). As of 2009, it serves over 16,000 unique users each month and handles over 500 gigabytes of data in 24 hours. There are three aggregation points (or base stations) that all traffic is forwarded to. The radios in the access points offer both GoogleWiFi (which has no encryption) and GoogleWiFiSecure (which uses WPA to encrypt the over-the-air traffic) service set identifiers (SSID). Google WiFi only requires its end users have a Google Account. Google offers a free virtual private network (VPN) software client called Google Secure Access (GSA) and maintains a list of other recommended third-party VPN software packages. Unlike a residential gateway, the network does not use network address translation (NAT): it provides a routable IP Address from a DHCP pool with a one-hour "DHCP lease" under the DNS domain wifi.google.com directly to the client PC. A mobile laptop user can roam through Mountain View and maintain the same IP address for at least the one-hour lease time.
While the equipment is of high quality and well-placed, actual coverage with a laptop with built-in Wi-Fi hardware is less than 100% of the claimed area; the system works well in commercially zoned areas but residential coverage areas are still spotty from block to block. There are areas in the city which do not have city owned light poles and thus do not have routers.
Around the summer of 2012, the network declined significantly. Users in some neighborhoods could not get connections, and the connections that were obtained in other areas had problems. Mountain View stated, "The city has received many complaints in recent months regarding the performance and reliability of the free Google Wi-Fi system in Mountain View, particularly at our library."
ComputerWorld reported that "An August field test by IDG News Service found it impossible to get a working connection at numerous points around the city, including City Hall and the main library." Users at the library do not use the Google WiFi connection but rather the wired Ethernet connections that the library makes available at many tables.
The city does not know what is wrong with the network except that it does not work. Google believes the problem is network has too much traffic on it. An article describes the network's decline.
Partnership with Starbucks
During the summer of 2013, Starbucks began replacing AT&T with Google Wi-Fi in its 7000 locations in the United States. As of May, 2015, the switch to Google is incomplete in many stores including stores in major cities such as Las Vegas and San Diego.

We started to get a lot of complaints," said Steve Rodriguez, the city's IT manager. "We generally get them in the library. From what I can tell it's pretty much not working anymore. We get asked a lot, 'What is going on with the Google wireless?'" Rodriguez's response? "I don't know.
