LTE Training in USA

NgnGuru Solutions & TelecomMentor Inc have partnered to offer a series of 4G LTE trainings in USA telecom space. These courses have been enhanced to include recent LTE evolutions & has been designed by NgnGuru/LteWorld technical experts. On-site corporate LTE training courses are also being offered now and can be customized to meet and exceed customer expectations.

NgnGuru Solutions' LTE training courses provide in depth understanding of the LTE/SAE signaling network, architecture and protocols. Upon completion of this course, the participants will have a sound understanding of LTE Air interface, E-UTRAN & Evolved 3GPP architecture.

LTE (Long Term Evolution) is 4G technology initiated by 3GPP to improve the mobile phone standard to cope with future technology evolutions and needs. Requirements include reduced cost per bit, increased service provisioning – more services at lower cost with better user experience, flexibility of use of existing and new frequency bands, simplified architecture, open interfaces and reasonable terminal power consumption.

Courses offered by NgnGuru Solutions does not require any previous knowledge or understanding of LTE, for more information download wireless training catalog or send an email tosupport@ngnguru.com.

LTE eLearning module is also available for remote/online learning, download eLearning training catalog for more information.

3GPP seminar was held on 24th May in Moscow. The 3GPP Seminar: Evolving Networks to LTE – 3GPP Perspective featured technical presentations and a Panel session with the main Russian Operators, where the road-map to LTE was discussed.

Few days earlier Russian opertor Yota had declared to go LTE way, see Scartel to abandon Wimax, aims for LTE. Yota operates on the same bands as Clearwire (2.5 GHz).

What is LTE?

LTE (Long Term Evolution) is initiated by 3GPP to improve the mobile phone standard to cope with future technology evolutions and needs. 3GPP work on the Evolution of the 3G Mobile System started with the RAN Evolution Work Shop, 2 - 3 November 2004 in Toronto, Canada.

The main targets for this evolution are increased data rates, improved spectrum efficiency, improved coverage, reduced latency and packet-optimized system that support multiple Radio Access Technologies.

Architecture overview

---

The evolved architecture comprises E-UTRAN (Evolved UTRAN) on the access side and EPC (Evolved Packet Core) on the core side.

The figure below shows the evolved system architecture

In E-UTRAN, eNBs provide the E-UTRA user plane protocols (PDCP/RLC/MAC/PHY) and control plane (RRC) protocol which terminates towards the UE.

The eNBs are interconnected with each other by means of the X2 interface. The eNBs are connected by the S1 interface to the EPC (Evolved Packet Core). The eNB connects to the MME (Mobility Management Entity) by means of the S1-MME interface and to the Serving Gateway (S-GW) by means of the S1-U interface. The S1 interface supports a many-to-many relation between MMEs / Serving Gateways and eNBs.
