The 4G & NB technology is used as a leading metering product of intelligent gas and water affairs in China, and has the following advantages: the 4G & NB gas and water meter is wide in coverage and has the capacity of supporting mass connection; the 4G & NB focuses on the low power consumption wide coverage (LPWA) internet of things (IOT) market, is a new technology which can be widely applied in the global scope, and has the characteristics of wide coverage, more connections, low speed, low cost, low power consumption, excellent architecture and the like; the method comprises the steps of establishing a mobile Internet of things comprehensive ecosystem cooperatively developed by NB (narrowband Internet of things), 4G (4G network containing LTE-Cat1, namely rate class 1) and 5G, meeting most of low-rate scene requirements by the NB, meeting medium-rate internet of things requirements and voice requirements by LTE-Cat1 (Cat 1 for short) and meeting higher-rate and low-delay networking requirements by a 5G technology on the basis of deepening 4G network coverage and accelerating 5G network construction.
For antennas for outdoor applications, different shapes of sealing rings (silicone rubber materials) are generally used for sealing. Generally, an O-shaped sealing ring is adopted, the sealing is realized by utilizing the compression elastic deformation of silicon rubber at the bottom of the O-shaped sealing ring after the antenna is assembled, but the sealing effect of the O-shaped sealing ring is related to the sizes of the sealing ring and the antenna sealing groove in the structural design of the antenna, and the silicone ring is easy to age under the influence of external factors such as sunshine, rain and the like along with the passing of the use environment and time, so that the waterproof effect is further influenced.
The built-in antenna can shield signals, antenna signals can not penetrate through the metal shell, the external antenna is mostly used for a wireless instrument of the metal shell at present, the external antenna is a small short rod antenna which is mostly used at present, the small short rod antenna is installed on the metal shell (an opening is formed in the metal shell) through threads (SMA joints), a signal is led out from the inside of the shell to the outside of the shell through a feeder inside the shell, and then the signal is connected with the small short rod antenna through a thread with a radio frequency patch cord (an SMA external thread female needle).
Such external antennas have several disadvantages:
1. the small short rod antenna is easy to lose, and is screwed together through threads, so that the small short rod antenna is convenient to detach, and once the small short rod antenna is lost, the instrument and the meter lose signals and cannot transmit data.
2. The antenna is not waterproof, the metal part of the antenna is easy to rust, water enters the inside of the instrument for a long time, and the rust can also affect signals.
3. The impact may cause the antenna to deform or directly knock the antenna apart.
Therefore, a cylindrical external waterproof antenna with good firmness is needed.
