Abstract: A sector-based base station includes at least one of a shared transmission RF local oscillator TX_LO, a shared receiving RF local oscillator RX_LO, a shared digital signal processing unit, and a shared transmission feedback unit. A technical solution of sharing an intermediate RF unit circuit in the sector-based base station is adopted, so as to reduce the number of elements used in the circuit without sacrificing the communication capacity of the base station. As such, the reliability index of a single board is improved, and the system reliability is also enhanced. Meanwhile, the material cost and the time required for debugging are both reduced, thus lowering the cost of the base station.

Abstract: A wearable device includes: a metal middle cover, a metal bottom cover, a printed circuit board PCB, and a gap. The metal middle cover encircles the wearable device for a whole circle and serves as an exterior of the wearable device. The metal bottom cover is located under the metal middle cover and serves as a rear cover of the wearable device. The gap with a preset width exists between the metal middle cover and the metal bottom cover, and serves as a slot antenna of the wearable device. The PCB is in an inner side of the metal middle cover, and is located above the metal bottom cover. The PCB is electrically connected to the metal middle cover by using a feed point, and feeds power to the metal middle cover.
