4 FAQs about PC communicates with LTE base station

How does LTE work?

All LTE devices have to support (MIMO) Multiple Input Multiple Output transmissions, which allow the base station to transmit several data streams over the same carrier simultaneously. All interfaces between network nodes in LTE are now IP based, including the backhaul connection to the radio base stations.

What are LTE EPC emulators?

The LTE EPC Emulators from Polaris Networks offer an easy-to-use, feature-rich and low-cost alternative to replace real EPC elements in a test network. The EPC Emulators include the MME, SGW, PDN-GW, HSS/AAA, PCRF, MBMS-GW, MCE, ANDSF and ePDG Emulators and can be used together to simulate the complete LTE Packet Core.

How does lteenb work?

LTEENB allows to build a real 4G LTE / 5G NR base station (called an eNodeB (4G) or gNodeB (5G)) using a standard PC and a low cost software radio frontend. All the physical layer and protocol layer processing is done in real time inside the PC, so no dedicated hardware is necessary. NB-IoT and Cat-M1 devices are also supported.

What is a standard LTE system architecture?

A standard LTE system architecture consists of an Evolved UMTS Terrestrial Radio Access Network, more commonly known as E-UTRAN, and the System Architecture Evolution, also known as SAE. SAE's main component is the Evolved Packet Core, also known as an EPC. The E-UTRAN is comprised of: The EPC is comprised of:
