What is LTE positioning protocol?
LTE Positioning Protocol (LPP) is a new protocol for LTE, although Secure User Plane Location (SUPL) version 2.0, remains as a headstone User Plane protocol which enabling LBS and emergency services on the networks, with some help from positioning techniques such as Wi-Fi positioning.
What is OTDOA in LTE?
Observed Time Difference Of Arrival (OTDOA) is also a Release 9 positioning method, in which the UE measures the downlink Positioning Reference Signal (PRS) time difference of arrivals of several neighbor cells in comparison to a reference cell.
What is LPP protocol?
LTE Positioning Protocol (LPP) [2] is the protocol used for C-Plane LBS sessions. The data link is used as the bearer for handling the LBS session and for transport of the assistance data messages.
What is Femtc?
The Fire and Evacuation Modeling Technical Conference (FEMTC) is an biennial international event, hosted by Thunderhead Engineering, featuring technical presentations from industry experts. FEMTC 2020.
How does LTE UE positioning works in e utran?
UE Positioning function is required to provide the mechanisms to support or assist the calculation of the geographical position of a UE. Positioning functionality provides a means to determine the geographic position and/or velocity of the UE based on measuring radio signals. …
What is 5G positioning?
5G positioning is a natural component in many anticipated 5G industrial use cases and verticals such as logistics, smart factories, autonomous vessels and vehicles, localized sensing, digital twins, augmented and virtual reality.
What is enhanced cell ID?
Enhanced Cell ID, E-CellID, or E-CID is a positioning feature introduced in rel9 E-UTRA (LTE radio). The UE reports to the network (ESMLC) the serving cell ID, the timing advance (difference between its transmit and receive time) and the IDs, estimated timing and power of the detected neighbor cells.
Which is light weight IoT protocol?
The light weight protocol Message Queue Telemetry Transport (MQTT) is used for data transmission between the IoT devices. The result analysis shows that the light weight protocol MQTT is 30% efficient for data transmission in SDN IoT architecture.
Which protocol is used in presentation layer?
Some examples of presentation layer protocols are SSL, HTTP/ HTML (agent), FTP (server), AppleTalk Filing Protocol,Telnet, and so on.
What is e SMLC in LTE?
The E-SMLC processes the location services request which may include transferring assistance data to the target UE to assist with UE-based and/or UE-assisted positioning and/or may include positioning of the target UE. The SLP is the SUPL entity responsible for positioning over the user plane.
Will 5G improve location accuracy?
Consumers with a cellular phone will also experience accurate positioning through 5G. It is expected that with some reasonable density of deployments in urban areas, 10 meters (m) positioning accuracy can be achieved.
How accurate is 5G positioning?
Inside buildings and in dense urban areas, the super-fast 5G (mmWave) should be capable of achieving a positioning accuracy of 1 meter or below.
Which is the operating band for 4G LTE?
From Tables 5.5-1 “E-UTRA Operating Bands” and 5.6.1-1 “E-UTRA Channel Bandwidth” of 3GPP TS 36.101, the following table lists the specified frequency bands of LTE and the channel bandwidths each band supports. Superseded bands are indicated by a grey background.
Are there any LTE bands not yet deployed?
These bands were defined by the 3GPP, but have never been deployed commercially or supported by commercial devices. The following table shows the standardized LTE bands and their regional use. The main LTE bands are in bold print. Not yet deployed are not available (N/A).
Which is the highest frequency band for LTE?
Frequency bands Band ƒ (MHz) Common name Uplink (MHz) Downlink (MHz) 24 1600 Upper L‑Band (US) 1626.5 – 1660.5 1525 – 1559 25 1900 Extended PCS 1850 – 1915 1930 – 1995 26 850 Extended Cellular (CLR) 814 – 849 859 – 894 28 700 APT 703 – 748 758 – 803
Are there any LTE bands that allow global roaming?
Networks on LTE bands 38, 40 (LTE-TDD) may allow global roaming in the future (ITU Regions 1, 2 and 3). Networks on LTE band 8 (LTE-FDD) may allow global roaming in the future (ITU Regions 1, 2 and 3).
