High-Concurrency, High-Bandwidth, and Low-Latency Access Requirements
A Wireless Network Can Not Meet the Access Requirements in Classrooms.
- Air interface resources are limited, and multiple terminals interfere with each other, making connections unstable in high-density access scenarios.
- The battery of a terminal lasts shorter in the case of wireless access.
- Varying latencies caused by signal strength changes and interference make users feel dizzy.
- The battery of a head-mounted display lasts for about 2 hours, and takes about 2 hours to be fully charged. Charging is inconvenient and requires a dedicated charging cabinet.
Huawei All-Optical Smart Classroom Solution:
- Optical cards deployed on desktop and connected to terminals in wired mode can ensure stable bandwidth higher than 100 Mbps for each user.
- Data and power can be transmitted over the same cable.
- Fully meets the connection capacity requirement and provides high bandwidth, low latency, and low jitter, delivering premium experience.
All-Optical Smart Classroom Deployment Solution: Optical Card + Photoelectric Composite Cable + Optical Gateway
- On the desk: A 1.5 m USB cable connects to terminals such as the VR helmet to transmit data and power.
- In the desk: A small-sized optical card connects to the photoelectric composite cable on the network side, and provides a USB port on the user side (power supply + communication).
- Cable trough: A photoelectric composite micro optical cable that is flexible, thin, strong, and easy to operate can work at any distance within 250 m.
- Teaching device cabinet: The cabinet can be installed anywhere in a classroom or weak-current room to house carrier-class splitters, DC power modules, and gateways.
- Campus network: 1 or 2 (optional protection) optical fibers are routed into each classroom.
