LTE (Long Term Evolution) BASIChttp://www.3gpp.com/LTE

Present Release -> 3GPP Rel-8 (Dec’08).Upcoming Release -> 3GPP Rel-9 (Dec’09)

ALU TLA2.1/LE2.1 supports only Rel-8 features. TLA3.0/LE3.0 will support few features of Rel-9 (ex. MCBS)

- LTE – 3.9G ; LTE_Advanced – 4G -> Can be on TDD or FDD

-DL - OFDM ; UL - Single-Carrier FDMA

-Very low latency -> VERY IMPORTANT

-Support of Self-Organizing Network (SON) operation

- Support of variable bandwidth - 1.4, 3, 5, 10, 15 and 20 MHz

Present ALU release supports only 10 & 20 Mhz on TDD.

LTE ALU Equipment Naming Used for BhartiTDD LTE Version - LE2.1 / TLA2.1 • eUTRAN:-• eNodeB – 9926 d2uv4 + 9442 RRH

• Transport:-• eNB Access - 7705 SAR-F• eNB Aggregation - 7705 SAR-8• Network Aggregation - 7750 MLS

• ePC:-– Signaling:-

• MME – 9471 (ATCA)• PCRF – 5780 DSC (ATCA) – SUN server for Trial.• HSS – 8650 SDM (ATCA)

– User Traffic:-P-GW / S-GW – 7750 (Service Routers - with ISM)

Note:-

ATCA – Advanced Telecommunication Computing Architecture ; Achieves 5 9’s – 99.999% reliability

Apart from above primary equipments , the below will be additionally used

-Fortinet Firewall 200B as part of test cases requirement

-Brekeke SIP server & MIRAL SIP client for VOIP testing –> SIP server will be used as an application server.

-ALU Media Portal Server – ALU Internal Server for testing LTE applications.

-RESTFULL Application Software – For invoking commands in Af interface for application servers.

ALU LTE RELEASES - BASIC

Used for Trial alone. Issue with LIS (only signaling can be read. Data can be tapped in LE3.0) – Not yet finalised.
