Mobile Health provides medical services and information through the use of mobile communication technologies such as PDAs, mobile phones and satellite communications. For mobile Internet applications, medical health applications are the main applications. The emergence of mobile medical care has changed the traditional medical habits of the past, making medical services at your fingertips. The entire medical process is no longer constrained by time and place, alleviating the shortage of manpower in the medical industry . At the same time, hospitals can use mobile IoT technology to improve service efficiency, reduce medical errors, control medical costs, and improve medical experience. In the future, PC-based medical applications will gradually migrate to mobile terminals, and the importance of wireless networks as a conduit for carrying mobile medical services data transmission becomes more and more obvious. A set of high-reliability, high-bandwidth, high-availability wireless networks has become one of the core indicators for measuring the level of hospital information.
There are four major trends in the future hospital mobile medical business:
1) Mobile medical care: nurses use the PDA to complete “three check seven pairsâ€, patient information entry, patient identification barcode identification, medical information inquiry, vital signs entry; doctors use PAD, cart and other terminals to complete the check of patient basic information, call PACS Information, diagnostic entry, medical order entry, writing medical records;
2) Medical Internet of Things: The broad medical Internet of Things can be understood as “the Internet connected by objectsâ€, that is, information such as radio frequency identification (RFID, RFID+Internet), infrared sensors, global positioning systems, laser scanners, gas sensors, etc. Sensing device, a network that connects any item to the Internet according to a contracted agreement, exchanges information and communicates to realize intelligent identification, location, tracking, monitoring and management;
3) Pocket Hospital: By using the Pocket Hospital APP, the patient realizes functions such as appointment registration, indoor path planning, asset personnel management, information push, recording parking space, wireless big data analysis, and medical procedure reconstruction on the mobile terminal;
4) Medical Multimedia: Through a wireless network, it carries various services such as video, voice, image and data, such as telemedicine , PACS cart, WIFI voice call, wireless monitoring and so on.
First, customized wireless network coverage
With the explosion of new applications such as mobile medical, handheld hospitals and Internet of Things technologies, traditional hospitals are gradually transforming into future hospitals. In the future construction of the hospital, the hospital faces many difficulties. The wireless network and the Internet of Things signal coverage have repeated construction lines, multiple sets of power supply systems, and high management costs. The hospital urgently needs a new wireless platform that can carry mobile medical technology, smoothly upgrade and expand the Internet of Things applications, reduce the difficulty of operation and maintenance, and unify the applications, devices and personnel on the management platform.
Huawei Medical Mobile IoT Solution provides customized platform-level AP products for the medical industry. It supports the expansion of RFID, ZigBee, Bluetooth 4.0 and other functions of any third-party vendor while satisfying WIFI coverage. The hospital can make unified planning for WiFi-based mobile medical applications and Internet of Things applications, implement them step by step, and smoothly transition to IoT hospitals, avoiding repeated investment in the construction process. Huawei Medical Mobile IoT Solution provides a refined and customized wireless network coverage solution.
Covered by an agile distributed solution in areas such as wards and operating rooms, as shown in Figure 1. The whole solution consists of a central AP and a remote module RRU, and one central AP can control up to 48 remote modules. The central AP is responsible for spectrum analysis, roaming switching, load balancing, and association control. The remote module RRU is responsible for radio frequency control and air interface management. The characteristics of the program:
1) Zero roaming: the service has no packet loss interruption and meets the requirements of mobile service continuity;
2) Dual-frequency room: 2.4G, 5.8G dual-frequency dual-flow room coverage per room, no blind spots, signal strength better than -65db;
3) Avoid construction: the remote module is a standard 86-box size, which can be replaced by existing information points in the room to avoid punching construction;
4) Precise positioning: room-level positioning, which can locate the terminal equipment connected to the remote module in real time;
5) Flexible expansion: Extend any third-party Internet of Things and Bluetooth service applications through the remote module or the standard RJ45 interface on the central AP;
6) Simplified management: Network management uses the central AP as a node to simplify the network management topology.

In the open areas such as clinics and aisles, the Huawei IoT AP4050DN-E is used to cover high-bandwidth and high-density access, and through the built-in three IoT card slots and external standard POE interfaces. Can expand the rich IoT function, as shown in Figure 2.
Industrial 100Hz LiDAR Solutions
Industrial Laser Distance Sensor of the IT02S & IT03M series are designed for measurements of moving targets. The LiDAR distance sensor is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 3 centimeters and as far as 15 meters! The LiDAR laser sensor is widely used in many innovative applications on the market, including smart dustbin, unmanned supermarket etc.long distance control system.
Application areas of the sensor are:
> Harsh environments, like outdoors in strong sunlight
> Black surface can be up to 8m
> UAV/Drone Systems
> Intelligent Parking
