Landline, IP and cellular phone services may or may not be available in an emergency, while satellite phones and 2-way radios are often more reliable means of communicating. Having multiple ways to communicate is a very good plan.  \n“LANDLINE” PHONE SERVICE is the oldfashioned Plain Old Telephone Service (POTS) that works over twisted copper wire. This is steadily being replaced by IP and cellular phone service. While some providers like AT&T still support landline service, they typically no longer install it new. And in most cases if landline service is canceled, it cannot be reinstated.  \nLandline phone service should continue to work after a disaster--but only if the  \ntelephone lines are intact and the service provider infrastructure (e.g. a local switching center) has power and is functioning properly. A simple corded phone with landline service may still be desirable for emergency use as it does not require its own separate power. However, there’sno guarantee that it will continue to work after a major disaster or an extended power outage.  \n“IP” (INTERNET PROTOCOL) PHONE SERVICE runs over the Internet. This is also referred to as VoIP (Voice over IP) . This service is offered by Internet providers such as Comcast, AT&T and Sonic. Regular phones plug into the Internet modem or gateway in the residence. When new phone service is installed, it most likely will be IP-based.  \nInternet service requires power for the residential modem or gateway. IP phones may work after a major disaster or power outage, but only if:  \n– there is local (household) power or backup power from storage battery/ UPS, solar, generator, etc, and,  \n– the cable, phone or fiber optic lines are still intact and the service provider infrastructure has power and is functioning properly.  \n| CELLULAR PHONE SERVICE relies on cellular towers that connect with cell phones via radio signals. Cell towers range from tall antennas with generator back-up to small antennas mounted on telephone poles, called a Distributed Antenna System, each with battery backups (which may run down and disrupt service during a power outage.) Cell phones also need to stay charged. | |\n| --- | --- |\n| Cell towers are designed to handle a certain number of connections and amount of data at one time. During or after a major disaster, cell towers may be overloaded and service disrupted. Towers can also be damaged. Mobile cell towers (CoWs-Cell on Wheels) can be deployed, but may take some time to become available. One should not depend solely on cellular service for emergency communications. |  |\n\n\n| | SATELLITE (SAT) PHONE SERVICE relies on satellites in orbit above Earth that connect with satellite phones via radio signals. Satellite service is very reliable during a local disaster or prolonged power outage as long as the satellite phone stays charged. Sat phones can be used almost anywhere outdoors as they don’t rely on towers or similar infrastructure. Some satellite location trackers (Garmin inReach, ACR, SPOT, etc.) can send text messages as well. |\n| --- | --- |\n| The main disadvantage of satellite phones has been their higher cost for both the phone and especially for the service, compared with cell phones. Satellite phones and location trackers also do not typically work indoors or even under dense tree canopies as they need direct line-of-sight to the satellite. The growing Starlink ([www.starlink.com](www.starlink.com)) system provides Internet and phone service via low-orbit satellites, and may be a useful means of communicating as it becomes more generally available. Newer cellular phones (e.g. iPhone 14) can also send and receive text/SMS messages via satellite. |  |\n\n[www.oaklandfiresafecouncil.org | 510.575.0916 | info@oaklandfiresafecouncil.","cbCailo4MrDyZZfn","https://ap.wps.com/l/cbCailo4MrDyZZfn","pdf",264221,"English","# Oakland Firesafe Council - Emergency Communications\n## Communications during disasters\n## Landline phone service\n## IP (Internet Protocol) phone service","[{\"question\":\"Why are multiple communication methods recommended during a disaster?\",\"answer\":\"Because phone and internet services may be unavailable or unreliable depending on power, infrastructure, and line damage.
