The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station. This protocol is specified by 3GPP in TS 25.331 [2] for UMTS, in TS 36.331 [3] for LTE and in TS 38.331 [4] for 5G New Radio. RRC messages are transported via the PDCP-Protocol.
In telecommunication, a public land mobile network (PLMN) is a combination of wireless communication services offered by a specific operator in a specific country. [1] [2] A PLMN typically consists of several cellular technologies like GSM/2G, UMTS/3G, LTE/4G, NR/5G, offered by a single operator within a given country, often referred to as a cellular network.
RRC: [8] Between others it takes care of: the broadcast system information related to the access stratum and transport of the non-access stratum (NAS) messages, paging, establishment and release of the RRC connection, security key management, handover, UE measurements related to inter-system (inter-RAT) mobility, QoS, etc..
California first announced a plan in 2020 to require that by 2035 at least 80% of new cars sold be electric and up to 20% plug-in hybrid models.
In 2004 the FCC developed a new band plan where narrowband operations are provided in 806–816 and 851–861 MHz ranges while wideband operations are allowed in 817–824 MHz and 862–869 MHz separated from narrowband services by a 1 MHz wide guard band. [6] The wideband services part of the SMR band was called ESMR (Enhanced SMR).
In 2026, 35% of new cars and light trucks sold in California would need to be zero-emission, according to ACC II, followed by 68% in 2030. EPA allows California to ban gas-powered new car sales by ...
Georgia's Republican lieutenant governor has unveiled a plan to roll back regulations in a similar style to what Tesla CEO Elon Musk is doing at the federal level in Washington, D.C.
5G NR (5G New Radio) [1] is a radio access technology (RAT) developed by the 3rd Generation Partnership Project for the 5G (fifth generation) mobile network. [1] It was designed to be the global standard for the air interface of 5G networks. [ 2 ]
