    en.wikipedia.org/wiki/List_of_WLAN_channels

    Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.

    Wireless network technologies. In telecommunications, 5G is the fifth-generation technology standard for cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the successor to 4G technology that provides connectivity to most current mobile phones. Like its predecessors, 5G networks are cellular networks, in ...

    IEEE 802.11ac-2013. *Wi‑Fi 0, 1, 2, and 3 are named by retroactive inference. IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band.

  5. Concerns over Chinese involvement in 5G wireless networks

    en.wikipedia.org/wiki/Concerns_over_Chinese...

    5G succeeds 4G LTE wireless technology. Developments have been focused on enabling low-latency communications, and promises of a minimum peak network speed of 20 gigabits per/second (20 times faster than the equivalent on 4G LTE networks), and uses within Internet of things and smart city technology.

  6. LTE in unlicensed spectrum - Wikipedia

    en.wikipedia.org/wiki/LTE_in_unlicensed_spectrum

    LTE in unlicensed spectrum ( LTE-Unlicensed, LTE-U) is an extension of the Long-Term Evolution (LTE) wireless standard that allows cellular network operators to offload some of their data traffic by accessing the unlicensed 5 GHz frequency band. [ 1] LTE-Unlicensed is a proposal, originally developed by Qualcomm, for the use of the 4G LTE radio ...

  7. 5G NR frequency bands - Wikipedia

    en.wikipedia.org/wiki/5G_NR_frequency_bands

    Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [ 1] which includes sub-6 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...

  8. Comparison of mobile phone standards - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_mobile_phone...

    GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA. WiMAX and LTE use OFDM . Time-division multiple access (TDMA) provides multiuser access by chopping up the channel into sequential time slices. Each user of the channel takes turns to transmit and receive signals.

  9. 5G NR - Wikipedia

    en.wikipedia.org/wiki/5G_NR

    5G NR ( New Radio) [ 1 ] is a radio access technology (RAT) developed by the 3rd Generation Partnership Project ( 3GPP) for the 5G (fifth generation) mobile network. [ 1 ] It was designed to be the global standard for the air interface of 5G networks. [ 2 ] It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G (fourth ...
