The company owns most of the submarine optical cables and microwave networks in the area and leases bandwidth resources to oil drilling platforms. Headquartered in Stavanger, Tampnet provides services for a large number of customers, including such oil giants as Shell, BP, ExxonMobil, and Statoil. Tampnet has extended its presence to Norway, UK, and Australia. Nearly 68 percent of the oil drilling platforms in the North Sea area connects to Tampnet's communications networks.

Constrained by WLAN protocols, the WLAN solution has low bandwidth and stability, which results in frame freezing, transmission interruption, and poor user experience.

SolutionBased on the rich experience in developing LTE end-to-end solutions and the customer's service requirements, Huawei has provided an all-in-one LTE wireless communications solution to provide data transmission services for the PIS and train-mounted video surveillance system.The solution is based on professional Huawei network planning and leverages LTE's advantages in access performance and service bandwidth in fast moving scenarios. This solution provides approximately 20 Mbit/s downlink bandwidth, which has set a good example for the live and HD PIS in the urban railway transportation

industry in China.The Huawei LTE system works in Time Division Duplex (TDD) mode, which enables the system to provide large-bandwidth uplink data transmission services with limited frequency resources, meeting the requirements of the wireless transmission of live HD surveillance videos.The system also uses a comprehensive Quality of Service (QoS) mechanism to perform refined service priority management. When the network is not congested, the system has low delay, minimized packet loss rate, and high QoS. When the network is congested, the system ensures that key services have the required bandwidth resources. The network bears the service data of the PIS and video surveillance system, which lowers the network development costs and lays a solid foundation for future wireless service expansion.T h e LT E i s a f u t u r e - p r o o f m o b i l e communications technologies and mainstream technology that facilitates the evolution from 3G to 4G.

World's First LTE BasedWireless BroadbandNetwork for PowerDistribution AutomationChina Southern Power Grid ChoosesHuawei's eLTE for Smart Grid' Project

BackgroundChina Southern Power Grid Co., Ltd. (China Southern Power Grid) is a large state-owned enterprise in charge of the investment, construction a n d m a n a g e m e n t o f p o w e r t r a n s m i s s i o n , transformation, distribution, etc.The company wanted to upgrade automatic control of its power distribution network with wireless communications technologies. From mid of 2011, the China Southern Power Grid has started the construction of small-scale wireless smart grid pilot.

Key ChallengesThe cons t ruc t ion o f a power d i s t r ibu t ion communication network faced the following challenges: Unreachable wired network for some areas

In the past, China Southern Power Grid constructed wired networks. However, i t was becoming infeasible to construct wired networks in some places such as old urban areas. These and other shortcomings in the existing system led China Southern Power Grid to investigate broadband wireless networks. High rent cost and poor quality of public wireless networksPublic carriers' networks, including 2G/3G network, failed to meet service requirements due to their poor SULYDF\KLJKUHQWFRVWDQGVRPHRWKHULQVXIFLHQWresources. China Southern Power Grid is forced to QGDEHWWHUZLUHOHVVFRYHUDJHPRGHEHFDXVHRIDOOof the above limitations.

sensitivity to the geographic environment, the short-distance wireless communications technology is only suitable for simple business application in a small range, unable to meet the full-service demands of power distribution automation.

SolutionHuawei submitted an ultra-bandwidth wireless automatic distribution communication network according to the service requirements of China Southern Power Grid. This solution is based on 4G eLTE technology, and it was designed to meet the needs of distribution automation, metering automation, and distribution network video surveillance services.This solution adopted an industry-dedicated wireless spectrum (1785 - 1805 MHz). Under the Non- LOS conditions, the solution could provide high bandwidth data access services in both fixed and mobile scenarios, and also some value-added services such as emergency communication and video surveillance.The solution provides the following features: High-bandwidth services with wide coverage and large capacity:For base station part, Huawei puts the RRU on towers and uses multi-antenna technology; as to terminal part, Huawei provides LTE outdoor data collection terminals which can support IP67 protection level, and they can connect with highgain antenna, DQGRIIHUPXOWLSOHPRGHVVSHFLFWRDYDULHW\RIGHSOR\PHQWscenarios. For example, in dense citys where 10 MHz bandwidth is used, Huawei's solution is below:

The average throughput of a single carrier can reach 20 Mbps, and coverage radius is as large as 4 km. The solution can satisfy the high-bandwidth transmission requirements of distribution automation and smart metering. A single carrier could support up to 1,200 online users, and the number of online users is up to 10,800 for one cell. The features well meet the requirement of large capacity for smart gird. Minimal access latency for precise controlAn automatic power distribution system must precisely control the power distribution services. Especially for remote control, the E2E delay should less than 1s. Take the application layer, network management system and other protocols into consideration, the maximum acceptable wireless access latency LVPV7RHQVXUHHIFLHQWSRZHUGLVWULEXWLRQ+XDZHLH/7(uses a minimum access latency solution to ensure it is less than 100 ms. Under "live" conditions, downlink access latency does not exceed 11 ms (average 8.8 ms), and uplink access latency does not exceed 59 ms (average 36.9 ms), which fully meets the requirements of mission-critical applications, such as SCADA. Multilevel QoSDifferent service applications have different priorities. The LTE system centralizes radio resource management to ensure end-toend Quality of Service (QoS) based on service levels. Huawei's LTE QoS mechanism develops priority strategies for multiple service levels, which ensures that important data, such as remote control data, is transmitted before other services.Huawei combined the LTE QoS mechanisms and power service needs together, and designed the specific priority strategy. The solution could fully support all the services; meanwhile, it can ensure the priority transmission of some important data such as distribution automation remote control data.

BackgroundChina Southern Power Grid is a large state-owned enterprise that handles the investment, construction, a n d m a n a g e m e n t o f p o w e r t r a n s m i s s i o n , transformation, and distribution across five of China's southern provinces. Guangzhou Power Supply Bureau is a large power supply company affiliated with China Southern Power Grid and provides power supply services to 10 Guangzhou administration districts and two counties. The company announced, in the Technology Development Planning component of its Twelfth Five-Year Plan, it would continue researching and applying new power distribution communications systems (based on wireless communications technologies) and focus on upgrading its automatic power distribution network. To accomplish these tasks, China Southern Power Grid would construct an integrated data collection platform and optimize the power distribution system's data analysis functions.

In mid-2011, China Southern Power Grid began building small-scale test zones to develop its wireless smart grid. Guangzhou Power Supply Bureau was chosen to pioneer the wireless smart grid and verify whether the smart grid distribution network could function reliably in highly populated cities. To this end, Guangzhou Power Supply Bureau selected Yuexiu District as the pilot area and set up base stations in the most populated district in Guangzhou.

Key ChallengesGuangzhou Power Supply Bureau is listed in the rankings of cities with the largest user density in China.
