  2. Cellular V2X - Wikipedia

    en.wikipedia.org/wiki/Cellular_V2X

    Cellular V2X (C-V2X) is an umbrella term that comprises all 3rd Generation Partnership Project (3GPP) V2X technologies for connected mobility and self-driving cars.It includes both direct and cellular network communications and is an alternative to 802.11p, the IEEE specified standard for V2V and other forms of V2X communications.

  3. Cellular repeater - Wikipedia

    en.wikipedia.org/wiki/Cellular_repeater

    A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.

  4. Remote radio head - Wikipedia

    en.wikipedia.org/wiki/Remote_Radio_Head

    When used to describe aircraft radio cockpit radio systems, the control panel is often called the radio head. In wireless system technologies such as GSM, CDMA, UMTS, LTE, 5G NR this radio equipment is remote to baseband units [1] such as BTS/NodeB/eNodeB/gNodeB or gNB. This equipment is used to extend the coverage of a baseband unit in ...

    Also, C-V2X provides a migration path to 5G based systems and services, which implies incompatibility and higher costs compared to 4G based solutions. The direct communication between vehicle and other devices (V2V, V2I) uses so-called PC5 interface.

  6. In-Building Cellular Enhancement System - Wikipedia

    en.wikipedia.org/wiki/In-Building_Cellular...

    As the industry evolves, most MNO networks are now made up of 3G based services and are migrating towards 4G based services. In-building cellular enhancement systems designed for 2G or primarily voice-based services may not be sufficient to support 4G services since signal strength and signal quality specifications become more stringent as the applications move from a voice-centric paradigm to ...

  7. C-RAN - Wikipedia

    en.wikipedia.org/wiki/C-RAN

    [1] [2] [3] C-RAN is a centralized, cloud computing-based architecture for radio access networks that supports 2G, 3G, 4G, 5G and future wireless communication standards. Its name comes from the four 'C's in the main characteristics of C-RAN system, "Clean, Centralized processing, Collaborative radio, and a real-time Cloud Radio Access Network ...

  8. Mobile phone signal - Wikipedia

    en.wikipedia.org/wiki/Mobile_phone_signal

    A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink). Depending on various factors, such as proximity to a tower , any obstructions such as buildings or trees, etc. this signal strength will vary.

  9. Picocell - Wikipedia

    en.wikipedia.org/wiki/Picocell

    Typically the range of a microcell is less than two kilometers wide, a picocell is 200 meters or less, and a femtocell is on the order of 10 meters, [6] although AT&T calls its product, with a range of 40 feet (12 m), a "microcell". [7]
