Mass communication network optimization project, when doing signal and covering, for cost-effective minimizing space, several signaling systeies transmit,
Combiner is often used to make multiple signals merge into a road signal.Therefore, in this antenna-feedback system, tri-frequency combiner is can not
The device lacked.
WLAN is the most entitled: Wireless Local Area Networks, and Chinese implication is WLAN.It is phase
When data transmission system easily, it utilizes the technology of radio frequency, uses electromagnetic wave, replaces the old-fashioned copper twisted pairs got in the way institute
The LAN constituted, is aloft communicatively coupled so that WLAN can utilize simple access architecture allow user
Through it, reach the ideal state of " information is changed with oneself, facility is walked all over the world ".Frequency band is 2400MHz-2500MHz.
Owing to mobile communication high speed development has multiple network to exist simultaneously, existing substantial amounts of communication network optimizes project to be done
When signal covers, it is desirable to reduce space is cost-effective, the combiner using a kind of multiple signals to merge into a road signal is reached
To unlike signal system transfers.But conventional product needed many places coupling welding, adds man-hour, wastes the time.
