Large-scale activities 5G business requirements

5G network applications mainly include cloud VR/AR, HD live streaming, video surveillance, telemedicine, remote control, cloud games, etc., while HD live streaming, VR/AR, machine vision, remote consultation and other indoor services, the overall process has high network speed requirements。For different application services, how does 5G technology guarantee field effects?

●4K/8K HD live broadcast: 5G live broadcast can return high-definition images in real time to achieve 360-degree panoramic HD and 10x zoom effect。

● VR live broadcast: Live broadcast of star concerts and large-scale events through 5GVR technology, enabling users to get an immersive experience。

● Security: The security work of large-scale events is very important, and the 5G network can provide more intelligent operation and clearer image recognition security video surveillance means。Among them, AR glasses can improve security efficiency through face recognition technology, intelligent robots can carry out ground security inspection, and CPE return equipment uses 5G network to return 4K high-definition inspection images to complete routine security checks。

Large-scale event network security scheme

Large-scale events are generally held in the venue, which is a typical indoor coverage scenario with high business requirements。Large venues usually have large area, large span of single buildings, and mainly steel frame structure, resulting in limited antenna installation points, empty scenes without shelter, and more difficult to cover the area and interference control。

Business characteristics

Data services demand more than voice services. Upload services demand more. Uplink traffic accounts for more than 40% of total traffic。

(1) Spectrum planning

For venues hosting large-scale events, all indoor and outdoor frequency bands involved in 2G, 4G, and 5G wireless networks need to be considered。When formulating the frequency planning strategy, the indoor and outdoor different frequency networking or wrong frequency networking should be the main one. Even if the same frequency networking is used, various means should be taken to control and reduce interference。For the reasonable planning of 2G, 4G and 5G frequency points of indoor venues, divide the communities according to business needs, and try to consider the convenience of splitting the communities in the subsequent expansion。

(2) Equipment selection

5G indoor coverage equipment can preferentially choose to use an external antenna distributed base station, and use photoelectric composite cables to support remote unit RRU with a maximum distance of 200 meters。Due to high capacity requirements, 4T4R distributed leather base station equipment should generally be selected, which can provide good coverage and high capacity compared with traditional indoor distribution systems, but also easy to flexibly expand capacity。This we can refer to Beifeng BF-RRU952 RF remote equipment, this equipment as a distributed base station RF part, the product design fully considered the user in the business, capacity, transmission, power, installation, maintenance and other aspects of the needs。The whole machine meets IP67 dustproof and waterproof grade，Integrated lightweight design，Support pole type, wall type and other installation methods，It is convenient for outdoor deployment in tall buildings and flexible deployment in upper towers，Thus, the feeder length is shortened, the signal loss is reduced, and the coverage of the base station is expanded，Even when it comes to big sporting events like the Olympics，It is also easy to use different outdoor environments。

(3) Networking scheme

For indoor coverage base stations in venues with high traffic user dense scenes, if distributed base stations are selected, multi-frequency and multi-mode equipment should be the main equipment, and meet the multi-standard requirements of 2G, 4G and 5G networks at the same time。BF-TR951 Stack deployment digital cluster base station, support PDT cluster /DMR cluster working mode, support a variety of combiners, support diversity reception, etc. It is suitable for a wide range of cluster networking and large-capacity indoor deployment scenarios。The base station provides rich applications such as voice intercom, trunking scheduling, data transmission, network management and positioning systems, providing mission-critical wireless communication customers with secure and reliable voice communication and high-speed data transmission capabilities。

(4) Emergency support plan

The importance and influence of large-scale activities are extremely high, it is necessary to ensure the normal operation of the network, and emergency plans should be implemented for emergencies to ensure the smooth operation of business。BF-TR8500 digital repeater fully meets the needs of wireless communication applications involving large area coverage, cross-area coverage and high network sensitivity;The application of the same frequency co-broadcast and intelligent IP interconnection further solves the pain points of some professional users, such as frequency resource shortage, cross-region command and dispatch。

Large-scale activities are the concentrated embodiment of high service in 5G indoor coverage scenarios. Wireless network security solutions need to be considered in many aspects, such as service prediction, frequency planning, capacity planning, device selection, networking scheme, and emergency plan, so as to achieve high network capacity and high reliability, and ensure good service experience for users。
