wireless home phone service is a service that allows ordinary wired phones to connect to mobile networks, as if it were a mobile phone. This is an example of a wireless last mile connection to a public switched telephone network, also known as a wireless local loop.
A small device, about the size of a home wireless router, contains the necessary electronics that allow regular old telephone services to be provided for one or two phone jacks on the back of the unit, as well as having a small radio antenna and transceiver for the wireless side of the connection. The LED indicator light on the front usually indicates signal strength and waiting voicemail messages. The device usually can not provide enough ringing current for more than one phone and one external device, such as an answering device or base station for cordless phones. For this reason, it is not advisable to connect this device to the home wiring (which also requires disconnection of cables in the network interface device, just as when a cable phone or other entire home VoIP service is installed). A rechargeable battery backup is usually provided to run the device during a power outage lasting no more than several hours, much less idle time than the actual mobile device.
The wireless home telephone service provides far more alternatives to existing phone companies than any other competitor has been able to provide where local loop unbundling has taken place. If the secondary line on the mobile plan is not expensive, the WHP line can cost only 10 dollars per month, using minutes of airtime (mobile phone) not used by mobile phones on the plan. Unlimited packages typically run around $ 20 per month, much less than unlimited plans for actual mobile devices, and significantly less than unlimited landline, and are comparable to low-scalable service. This has led users to port their existing phone numbers to their mobile plans, even though monthly prepayment services are also available. It also allows the physical portability of home phone services, whether temporarily (like when spending summer or winter traveling by recreational vehicle), or when making a permanent relocation to another area code. WHP can also be combined with mobile hotspots in one device, which also typically have cheaper data packets than smartphones or special hotspot devices, though still far more per gigabyte than broadband cable Internet.
The disadvantage includes depending on one source for the phone, so that if the nearest cell tower experiences a power outage, no home phone is used as a backup for anything but an emergency call. Audio compression, audio level compression, and audio data compression used in cell phones also damage data signals used by modem-based devices, including fax machines, medical monitoring devices, and even set-top boxes for satellite TV, preventing their use for anything. except to display caller ID for incoming calls.
In the United States, the WHP service is offered under various names (usually Wireless Home Phone or Home Phone Connect) by Sprint Nextel, T-Mobile USA, AT & amp; T Mobility, Verizon Wireless, Ting Inc. (via Sprint), and Straight Talk.
