ONGC BWA Project-Technology and Construction

ONGC BWA PROJECT

Project Objectives To provide stable and reliable voice and data communication

Mehsana, Ahmedabad, Baroda, Cambay, Ankleshwar and Gandhar in Western Onshore & NEELAM offshore complex. Application of the network Real time---Voice, SCADA Non real time Internet, Intranet, SAP Bandwidth Intensive future applications Video conferencing

CONTD

Upgrade the present communication infrastructure for future bandwidth intensive applications such asvideo conferencing, Video streaming, Online visual monitoring & control The present infrastructure is not sufficient & able to handle these requirements Plan to upgrade the existing infrastructure by using broad band terrestrial communication including fiber & broadband wireless access technology (4 G)such as WiMAX & LTE

ADVANTAGES of WiMAX

Bandwidth Efficient >3G technology with sector data throghput is 22 Mbps /10 MHz . For multisector base station (4 sector ) data throughput will be 80 Mbps (present channel bandwidth of ONGC is 14 MHz/ base station expected to give 40 Mbps dat throughput) Low cost compared with existing Satellite & leased line communication infrastructure Existing infrastructure is not capable of handling bandwidth intensive real time video applications due to bandwidth limitation Fast internet browsing & data transfer. Easy & cost effective maintenance.

What is WiMAX 802.16 Introduction 802.16 MAC Highlights 802.16 Reference Model MAC Convergence Sub-Layer (CS) MAC Common Part Sub-Layer (CPS) MAC Privacy Sub-Layer (PS) Questions

What is WiMAX? Worldwide Interoperability for Microwave

Access (WiMAX) is the common name associated to the IEEE 802.16a/d/e standards. These standards are issued by the IEEE 802.16

subgroup that originally covered the Wireless Local Loop technologies with radio spectrum from 10 to 66 GHz.

WiMAX is NLOS (Non Line of Sight) technology Works on Multipath received signal Frequency reuse by x-polarization is not possible Frequency reuse is possible by height difference of base stations Use of OFDM (Orthogonal Frequency Division Multiplexing) Technique which able to operate in larger delay spread in NLOS & Multipath signal environment. Use of adaptive modulation (64QAM to BPSK) for efficiency, reliability & robustness Use of adaptive bandwidth for efficient use of channel utilization

IEEE 802.16 -- IntroductionCoverage range up to 50km and throughput for 3.5 MHz channel bandwidth at different modulation

IEEE 802.16 MAC -- Highlights WirelessMAN: Point-to-Multipoint and optional mesh topology Connection-oriented Multiple Access: DL TDM & TDMA, UL TDMA;UL OFDMA &

TDMA, DL OFDMA & TDMA PHY considerations that affect the MAC

Duplex: TDD, FDD, FDX FDD BS and SS, HDX FDD SS Adaptive burst profiles (Modulation and FEC) on both DL and UL

Protocol-independent core (ATM, IP, Ethernet) Flexible QoS offering (CBR, rt-VBR, nrt-VBR, BE) Strong security support

Adaptive PHY

Adaptive Burst Profiles Burst profile: Modulation and FEC On DL, multiple SSs can associate the same DL

burst On UL, SS transmits in an given time slot with a specific burst Dynamically assigned according to link conditions Burst by burst

Trade-off capacity vs. robustness in real time

Duplex Scheme Support Time-Division Duplex (TDD) Downlink & Uplink time share the same RF

channel Dynamic asymmetry does not transmit & receive simultaneously (low cost) Frequency-Division Duplex (FDD) Downlink & Uplink on separate RF channels Full Duplexing (FDX): can Tx and Rx simultaneously; Half-duplexing (HDX) SSs supported (low cost)

IEEE 802.16 Uplink Service Classes

UGS: Unsolicited Grant Services rtPS: Real-time Polling Services nrtPS: Non-real-time Polling Services BE: Best Effort

CONTD.

UGS: Unsolicited Grant Services For CBR or CBR-like services, e.g., T1/E1. The BS scheduler offers fixed size UL BW

grants on a real-time periodic basis. The SS does not need to send any explicit UL BW req.

CONTD.

rtPS: Real-time Polling Services For rt-VBR-like services, e.g., MPEG video. The BS scheduler offers real-time, periodic, UL

BW request opportunities. The SS uses the offered UL BW req. opportunity to specify the desired UL BW grant. The SS cannot use contention-based BW req.

CONTD.

nrtPS: non-real-time polling services For nrt-VBR-like services, such as, bandwidth-

intensive file transfer. The BS scheduler shall provide timely (on a order of a second or less) UL BW request opportunities. The SS can use contention-based BW req. opportunities to send BW req.

CONTD.

BE: Best Effort For best-effort traffic, e.g., HTTP, SMTP. The SS uses the contention-based BW

request opportunities.

IEEE 802.16 MAC Privacy Sub-layer (PS)---DATA SECUIRITY Two Major Functions: Secures over-the-air transmissions Protects from theft of service Two component protocols: Data encryption protocol A client/server model based Key management protocol (Privacy Key Management, or PKM)
