This tag relates to Long-Term Evolution (LTE) mobile telecommunication standard.
For general cellular network related questions use /mobile.
For other mobile technologies use specific tags like /3g /gsm.
For other RF technologies consider tags like /wifi /bluetooth /irda.
LTE or Long-Term Evolution is also sometimes referred to as 4G, although it doesn't meet the 4G criteria as lined out by the 3GPP partnership project.
LTE is one of the standard mobile technologies, beside gsm and 3g, characterised by high data throughput rates. It offers data services for devices like mobile phones and modems. Voice services are supposed to operate over the data layer with help of solutions such as voip. For standard cellular network incoming and outgoing calls, Circuit-Switched fallback to other systems such as GSM or UMTS is performed by the network.
