2. 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.

3. 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 ...

   For example, a cell phone signal booster made for a very large home (up to 7,500 square feet) can cost up to $1,000, whereas boosters made for smaller homes (up to 3,500 square feet) can go for ...

5. 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 ...

6. MIMO-OFDM - Wikipedia

   en.wikipedia.org/wiki/MIMO-OFDM

   Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into ...

   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.
