Cordless telephonePortable telephone that connects to a landline Two cordless telephones 3 VTech cordless landline phones A Panasonic KX-TG2226B 2.4GHz cordless phone with answering machine A cordless telephone or portable telephone is a portable telephone handset that connects by radio to a base station connected to the public telephone network. The operational range is limited, usually to the same building or within some short distance from the base station.
TelephoneA telephone, commonly shortened to phone, is a telecommunications device that enables two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user.
Mobile phoneA mobile phone or cell phone is a portable wireless telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones (landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN).
Base stationBase station (or base radio station, BS) is – according to the International Telecommunication Union's (ITU) Radio Regulations (RR) – a "land station in the land mobile service." A base station is called node B in 3G, eNB in LTE (4G), and gNB in 5G. The term is used in the context of mobile telephony, wireless computer networking and other wireless communications and in land surveying.
TransceiverIn radio communication, a transceiver is an electronic device which is a combination of a radio transmitter and a receiver, hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes. These two related functions are often combined in a single device to reduce manufacturing costs.

TransmitterIn electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal transmission to a radio receiver. The transmitter itself generates a radio frequencyalternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves.

Telephone lineA telephone line or telephone circuit (or just line or circuit industrywide) is a single-user circuit on a telephone communication system. It is designed to reproduce speech of a quality that is understandable. It is the physical wire or other signaling medium connecting the user's telephone apparatus to the telecommunications network, and usually also implies a single telephone number for billing purposes reserved for that user.Tinsel wireTinsel wire is a type of electricalwire used for applications that require high mechanical flexibility but low current-carrying capacity. Tinsel wire is commonly used in cords of telephones, handsets, headphones, and small electrical appliances. It is far more resistant to metal fatigue failure than either stranded wire or solid wire. ConstructionTinsel wire is produced by wrapping several strands of thin metal foil around a flexible nylon or textile core.
Cell siteA cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed on a raised structure (typically on a radio mast, or tower) to create a cell, or adjacent cells, in a cellular network.*As an Amazon Associate I earn from qualifying purchases.
