7 LTE Offshore

8 LTE Offshore Why LTE? Challenges Solution Coverage and Performance The Road Ahead

9 Why LTE Tampnet needed a technology that could deliver: High symmetrical bandwidth to mobile or moving rigs and vessels Low latency ( <40ms RTD) and low jitter Easy and inexpensive installation on user end High spectrum flexibility due to cross-border network Future proof technology due to long construction times/long life offshore We wanted a large ecosystem of users, vendors, support, solutions, hardware etc High security for client data

10 Why LTE Chart Title Range Speed Latency LTE 3G 2G WiMax WiFi

11 Who uses LTE? 2014

12 A LARGE ECOSYSTEM

13 Challenges (and some solutions)

14 LTE Challenges Main Challenges Harsh Environment the most challenging one there is? Limited space and beds on vessels and platforms installation challenges ATEX and RF radiation issues Redundancy and rerouting, power loss on platforms, core network User Equipment Quality and Configuration Security of Data

15 Logged Heave on Gryphon during storm (8 Mbps continuous uplink/downlink on 21km from enodeb with 57m antenna height) 6 hour Test 9:20 15: % 12 hour Test 19:50 07:50

16 Pitch and Roll on User End

17 Flat Sea...less of an issue in LTE networks

18 RF Radiation Safe Distance calculations performed for all antennae ICNIRP and ITU recommendations used

19 ATEX and Safety Due diligence for ATEX zoning and installation environment performed before each install in cooperation with Platform Operator Assessment of Inadvertent Ignition of Flammable Athmospheres by RF radiation Calculations performed for all installation jobs

20 User Equipment Quality End user equipment does not have high enough quality yet (but getting there ) Tampnet is working with equipment vendors to improve quality and solve problems LTE consumers today are typically not industrial high end users but this will change!

24 Tampnet s Intensions with LTE As simple as possible - One uniform network covering all of the North Sea Norway, UK and Denmark (Netherlands) Same CPE and USIM will work on all base stations Monitored, dedicated, uncontended service with high availability A secure and reliable network for all interested parties Secure, dedicated and segregated traffic for each client Scalable layer 2 service Closed, dedicated Oil&Gas Service, enabling Layer 2 connectivity to shore from any asset Tailor made CPE solutions offshore specific Mobilility On-shore point of delivery tailored to customer needs Ethernet directly to client s address SOIL interconnect Internet (through a secure Layer 2 connection) Client IP/MPLS network interconnect (APN)

25 Build to robust and maintainable offshore spec ATEX Radiation Hazard Minimise cable loss Choose the right cables and connectors Choose the right antennae Careful design of power supply

26 Coverage and Performance

27 Speed and Range The range of an LTE base station depends mainly on frequency and antenna height Capacity decreases with range, but gain in uplink antennae may mitigate for some applications 40Mb Notes: Symmetrical bandwidth uplink/downlink 1800 MHz frequency band 20 MHz channel 20Mb 0 Mb 0 km 10km 20km 30km 40km 50km 60km 70km THE CURVATURE OF THE EARTH IS THE MAIN LIMITING RANGE FACTOR!

28 Speed (theoretical) vs bandwidth

29 Speed (theoretical) vs bandwidth

30 Coverage Tampnet performed a measurement campaign offshore, in order to test performance, and see how LTE functioned in our environment and for our use Successful campaign yielded good results (even better than expected) and gave us valuable input on propagation of LTE over sea. Conventional propagation models are useless offshore!

31 Gain over free space (db) Know your radio propagation theory Reducing antenna height from 40 to 30m gives 25dB gain! 10 Receiver antenna height gain over free space Placement of antennae is very important Effects of reflections can yield «surprising» results Antenna height (m) Curved Earth (including reflectance as a factor of incidence angle) Flat Earth (100% reflectance factor for surfaces and incidence angles)

41 The Road Ahead

42 What we know: Capacity demand WILL increase beyond our expectations ACCESS TO SPECTRUM IS KEY Users will demand always on - everywhere GOOD COVERAGE IS KEY Users will expect the same performance, security and reliability as from fibre or radio link solution BUILDING OFFSHORE INDUSTRY SPECIFIC LTE SOLUTION IS KEY

43 LTE Advanced is first step LTE Release 10, 11 and beyond will greatly increase the bandwith requires spectrum
