Agile and Safe Manufacturing Using Wireless Networks
Preface
Safety is the solid foundation of an enterprise's reliability, the basic requirement for an
enterprise's sustainable development, and the most important way to maintain an
enterprise's competitiveness. Strengthening safety management and enhancing safety level
is the key to enterprise survival and development. With the rapid development of China's
economic construction, and diversified enterprise property rights and operation and
management modes, the production safety situation becomes more complex , safety data
increases dramatically, especially in high-risk environments, remote areas, and safety
monitoring situation of mobile medium becomes increasingly prominent. Meanwhile,
production safety of the manufacturing industry faces more challenges caused by safety
problems, such as personal safety, material safety, equipment safety, productivity, quality
safety, and destruction of the nature and environment.
Traditionally, wired networks are used to ensure the production safety of the
manufacturing industry. On such networks, fiber optic cables are used to achieve safety
monitoring and dispatching. At the same time, operators' 3G wireless networks serve as a
supplement. However, remote and high-risk areas are hard for wired networks to cover,
and operators' 3G networks have coverage holes, low transmission reliability, and low
bandwidth. Therefore, using an LTE network that is dedicated for production and
supplemented with Wi-Fi coverage in hotspots as the safety monitoring wireless network
can help establish an efficient, quick, and reliable information system, get dynamic state

of production safety in time, improve production safety supervision, management
information level, and efficiency to ensure enterprises' safe production .
Challenges
The manufacturing industry faces the following problems in its safety monitoring and
dispatching:

Video monitoring does not cover all areas of factories and material safety
cannot be guaranteed. Large manufacturers, such as steel factories, have many
yards, warehouses, and logistics places that are far away from the main factory
area. Fiber optic cables cannot be deployed in these areas. In order to ensure the
safety of these places, operators' 3G networks must be used to carry out real -time
monitoring. However, these 3G networks provide unstable and poor video
transmission.

Monitoring of environment and energy medium is difficult and environment
safety cannot be guaranteed. The manufacturing industry has high energy
consumption and emission. Therefore, monitoring of gas usage, sewerage,
drainage and gas emissions is particularly important. There are a number of
monitoring points in a factory and many of the monitoring points are usually in
hazardous areas or far away from the main factory area. As a result, wired
networks require high costs or even cannot be deployed. When using operators' 3G
networks, capacity from multiple monitoring points is large and concurrent data
transmission is unreliable, resulting in untimely delivery of monitoring
information to the monitoring center.

Inefficient manual preventive maintenance leaves risks in equipment safety.
Equipment preventive maintenance is a routine in the manufacturing industry to exclude
accidents and predict equipment performance. Traditional manual preventive

maintenance inspection information is recorded in hard copies, including the task
assignment and standard. This method is inconvenient and prone to errors. During
working, information cannot be queried and input in a timely manner. In addition,
ineffective personnel supervision often causes intentional or unintentional
omission, inefficient inspection, and untimely exclusion of accidents.

Personnel enter hazardous areas by mistake and their lives are under threat .
Large manufacturers, such as steel factories, have many high-temperature, toxic,
and high-voltage areas. Although these areas have warning signs, onsite operators
often enter these hazardous areas by mistake due to misoperations and warnings
are not received in time, which may cause human injuries.

Vehicle management is difficult and dispatching is not timely. In the
manufacturing industry, most factories are built on a vast area. Enterprises often
use GPS positioning and 3G network transmission to manage and dispatch
vehicles and perform tracking monitoring. Since the factories are usually loca ted
in remote areas, many places have weak 3G signals or even no signal. Therefore,
unstable data transmission, inaccurate positioning, and untimely transmission of
dispatching information occur.

Untimely fault diagnosis leads to low production efficiency . Large
manufacturers, such as large-scale steel factories, usually have a number of
factories that are distributed in many different regions. Onsite equipment
maintenance personnel have limited experience and expert resources are
insufficient. If sudden faults occur, experts from headquarters are required to
provide onsite support, resulting in untimely equipment diagnosis. Consequently,
the production efficiency is greatly affected.
All the preceding problems and challenges are caused by the lack of enterp rise wireless
networks or poor performance of wireless networks. Therefore, deploying a dedicated
wireless network that features a high bandwidth, wide coverage, short delay and provides
diversified services such as HD video, big data, and voice services i s the only way for
enterprises to solve and meet the preceding problems and challenges.

Overview
Huawei eLTE broadband wireless network consists of the eCNS600 small core network
and DBS3900 distributed base station, and features small size, light weight, industrial
performance, and easy installation and deployment. LTE broadband wireless network has a
high bandwidth (downlink throughput: 100 Mbps, uplink throughput: 50 Mbps), wide
coverage (exceeding 20 km2 ), high mobility (supporting a speed of 120 km/h), and
supports concurrent big data transmission, HD video transmission, remote data collection,
broadband trunking services. The LTE broadband wireless network can effectively achieve
wide coverage of steel factories and ensures safety monitoring and real -time dispatching
of steel production. Huawei WLAN wireless network supports flexible networking an d a
high bandwidth and can supplement the LTE to provide wireless coverage of applications
and hotspots such as warehouse and offices, and achieve efficient and convenient
production and office operation.
To help manufacturing customers deal with safety monitoring and dispatching challenges, Huawei
provides an LTE + Wi-Fi-based IP bearer network for production and office on the basis of eLTE
broadband wireless network and leading Wi-Fi solutions and products. This LTE+ Wi-Fi-based
network not only solves safety monitoring and dispatching problems but also provides Wi-Fi in
office buildings to support office work. By using characteristics of LTE and Wi-Fi, this solution
enables LTE to bear vehicle logistics management, environment and energy medium test, factory
monitoring, equipment spot-check, Wi-Fi to position staff for their safety and provide a mobile
