Drone express, that is, through the use of radio remote control equipment and self-provided program control device operated unmanned low-altitude aircraft to carry parcels, automatic delivery to the destination, its advantages are mainly to solve the distribution problem in remote areas, improve distribution efficiency, while reducing labor costs. The main drawback is that the drones will not deliver in bad weatherForce, re-flight process, can not avoid human sabotage and so on. At present, SF Express has been available, but it has not been widely used.
If there is an obstacle ahead, it will automatically adjust the line. For example, when it hits the next few roadblocks, it will move its body and adjust its route through. If someone is walking some distance ahead, the car will adjust its speed according to the speed of the person to ensure that there is a certain safe distance between the person and the car.
Express delivery unmanned, refers to a drone or robot technology, the use of drones or robots to quickly deliver goods to the hands of customers. This type of service usually does not require a human receptionOr processing, completely completed by the machine, which greatly reduces the operating costs of logistics enterprises and the time cost of manual control, but also provides users with faster, more reliable and more intimate service. According to reports, a technology company in the university town of Shapingba District has developed the world's first Internet of Things module based on Beidou communication technology, which can pinpoint the location to the centimeter level, making it possible to send deliveries by drone.
UAV delivery advantages: to achieve express delivery automation, unmanned, information. Improve the delivery efficiency and service quality of express delivery in order to ease the demand for express delivery and express service3GPP introduced in the R5 protocol, it can greatly improve the user's downlink data service rate (theoretical peak up to 14Mbit/s) without changing the network structure of the WCDMA system, and greatly improve the defect that WCDMA does not support data-intensive applications. It is an important technology to improve downlink capacity and data service rate in WCDMA network construction.
HSDPA not only supports high-speed asymmetric data services, but also minimizes the cost of operators while greatly increasing the network capacity. It provides higher data transfer rates and higher capacity for UMTSA smooth evolution path, just like the introduction of EDGE in the GSM network.
H 1 means that the Hspa network is currently used, which is also commonly known as the 75G network. The full English name of HSPA is High-Speed Packet Access, an enhanced high-speed packet access technology, which is an enhanced version of HSPA. HSPA is HSPA High-Speed Packet Access.
From a technical point of view, HSDPA introduces high-speed downlink shared channelsHS-DSCH, which places functional entities in NodeB, uses shortened subframes (2ms), and employs several core key technologies, including: adaptive modulation encoding AMC (16QAM, high efficiency encoding), hybrid automatic repeat HARQ, and dispatch-based fast transmission.
TD-LTE (4G) /TD-SCDMA/GSM: Link adaptive technology can determine the capacity of the current channel according to the channel state information, and determine the appropriate code modulation mode according to the capacity, in order to maximize the transmission of information and improve the utilization of system resources. GSM/WCDMA/LTE: Through the WCDMA system and the special equipment technical monitoring platform security direct connection, to achieve the real-time upload of technical monitoring information, video images and other large-capacity data.
