The speed of 5G network rivals the broadband network; aside its capability of constructing the network systems between branches rapidly, the enterprise can also utilize the 5G network to build dedicated low latency networks for the transmission of the security sensitive data. The 5G Enterprise Private Network solution is designed for enterprises to have a large bandwidth, low latency, and seamless transmission with high mobility. The applying field includes factories, Science-Based Industrial Park, medical institute, logistics and also the project of police & fire department, port authority, power station, water station and emergency responding system.

There are four solutions regarding 5G Private Network solution – First is to apply the network slicing technology to separate a slice of the network for the dedicate enterprise logic network, using the technology such as Software Defined Networking and Network Function Virtualization to ensure every slice of network has its own QoS setting, storage and routing setting. The second solution is the enterprise private base station solution, the ISP will deploy the 5G base station to the assigned locations. Having a built 5G network on site is the advantage of this solution. However, to access enterprise services, it still has to connect to the Edge computing and the Core network of the ISP. The third solution is to have the Edge computing deployed at the assigned enterprise sites. By adding the Edge computing, the latency will be improved, but the users still have to access the internet via the ISP Core network. The fourth solution is to build an independent network at the enterprise site, which requires all three of the mentioned equipment. Compared with the second and third solution, this network system is more secure, on the other hand, the cost to build one will be way higher.
With different applying environments, building an enterprise private network may encounter different challenges such as the planning of the base stations and antennas, the signal interfering, the blind spot of the building and the large network demands for the operating devices. Due to the fact that the solution of Enterprise Private Network varies, the application may focus on the equipment or the device. The key of the system will be the quality of the connection, and it will be evaluated by the stability (package lost ratio) and speed (transmission rate)of the services.
When it comes to the evaluation of the 5G Enterprise Private Network system, apart from the mentioned challenges from the planning phase, the idea is to build a customized, unblocked highway for the registered vehicles only. The road will only allow the information to be transmitted internally, and it will be highly isolated to avoid the traffic jam and the security breach. That being said, building a private network may require a great investment in the early stage, and there will be continuous expenses for the maintenance. Thus, choosing a non-major brand product will be a good solution to lower the cost.
The ISP established the O-RAN alliance. Differentiated from the highly integrated enclosed hardware system, they divided the system into multiple hardware layers like the Radio Unit, the Distributed Unit, the Central Unit and other layers with various interfaces and control systems. Through the opened architecture, it can reinforce the autonomy function of the system, lower the budget of the investment, speed up the development and import, and elevate the flexibility and performance. Enterprise Private Network is an efficient solution to solve network congestion and data security. It will be a nice solution providing the network with large bandwidth and low latency to create the value and opportunity of the enterprise user market.
In terms of home entertainment applications, most operators are currently competing to launch mobile solution with fixed network in parallel with complementary integration. In the past, home entertainment was centered on cable TV in the living room. Later, it changed from watching TV to playing the mobile phone. With the introduction of smart TV, consumers have gone back using the big TV screen to connect the unfinished content on the mobile phone. The audience shifted from the cable TV and returned to the broadband service on TV. Although 5G technologies brings higher bandwidth, the cost of deploying 5G increases by the population coverage, and the indoor coverage of 5G technology is just not good enough as well. When consumers return home with their mobile phones, they will need to use Wi-Fi, wired broadband connection to visit the Internet, there will only be few people willing to put a small base station at home, or put the equipment on the balcony and other places where the 5G signal is not good. In addition, applications such as 4K and 8K TV, AR, VR, cloud games, etc. requires a lot of bandwidth. Using the mobile screen for the high quality content is not enough for the users already. Instead, the big screen in the living room is the most enjoyable service people desired. Therefore, in the consumer market, home entertainment applications eventually will become more popular than outdoor applications.
Through the integration of the last mile of optical fiber broadband, 5G expands the scale of the network, the lower the burden of network maintenance costs per capita, the more network users exists, the higher the value of the network. While controlling the cost of CAPEX construction, It can also bring in more ARPU revenue, and become a marketing method for operators to rush launching mobile and fixed network integration solutions at this stage. No matter from the perspective of mobile and fixed network services, core network construction, sales channels, or terminal equipment, mobile phones and TV is just a different device. Now most mobile apps can also be used on Internet TV, and more entertainment terminals will become IoT terminals.
ENTU 783 series is so called 10G fiber optical switch, or Ethernet Media Data Converter (MDC). The interface of ENTU 783 includes one 10G Ethernet port and three Optical SFP+ ports. With the physical quick setting dip switch on the back panel, the user can easily select from MDC mode to the Ethernet Switch mode. In order to interoperate with different line rates, it supports flow control which can send pause frames dynamically to control the transmitting rate so it won’t be overwhelmed with data packets. At the customer premise, ENTU 783 provides link protection, bandwidth combination and loop prevention.Deploying at the operators’ network, SNMP and RMON feature allows the operators to monitor remotely.As the functions like Q-in-Q, it can separate each user’s traffic while preserving the VLAN tag from the data. Overall, it is an ideal device to act as a demarcation point between the operators and the customers. ENTU 783 has the characteristics of light weight, high performance, and extended and stable communication distance. It is the best choice for operators and enterprises to deploy enterprise private networks, and effectively reduces the CAPEX capital expenditure of enterprise private network investment.
