Product Description:

· Outside antenna has magnetic feature to mount on the roof of vehicle

· Outside antenna distance should be at least 5 feet from inside antenna

· Recommended to mount outside antenna near rear end of the roof


Wireless Car Booster don’t need the mobile phone to be connected, it would amplify and send

the signals wirelessly inside the covered areas, therefore people can move around to make a phone call,

though they are limited to a 1-3meter radius

Q:WiFi repeater setting issues
You should enter the MAC address of each other on the router and repeater, so that the wireless relay can be carried out effectively.
Q:Wireless repeaters are restored to initial strength regardless of how weak the signal is What is the principle of a wireless repeater?
Radio is a radio signal repeater radio relay station! It is a middle long distance transmission amplification transmission equipment VHF radio! If we use mobile phone! It is visible from the spread of the linear wave! For transmitting antenna height and the ground surface is curved finite limit! It only in a few kilometers is transmitted within the relay! You need to set the interval of this relay station can realize remote transmission!
Q:A cable line can use two wireless repeaters simultaneously
A's LAN port comes up to B's LAN port, then closes B's DHCP service, and then the computer can connect to B, the same effect as A.
Q:Japanese fire automatic alarm system. How can I dial the repeater?
Fire control module is also called input and output module, which is an important part of fire fighting linkage control system. It is used in automatic fire alarm system to connect smoke exhaust valve, air supply valve, fire damper and so on. The module has a pair of normally open and normally closed contacts. The external contacts of the module are connected with the external circuit to realize the linkage control of the external equipment. Domestic fire alarm manufacturers are numerous, here introduces several input and output modules.
Q:How can I use a wireless repeater where there is no power?
Where there is no power supply, if the wireless repeater is 12V, it can be powered directly by the 12V battery.
Q:How can wireless AP (trunking) be used to connect wireless routers that shut down SSID broadcasts?
Wireless networks with SSID broadcasts have been closed, that is, wireless network names are hidden. Wireless Internet devices are unable to find the wireless network.
Q:Can wireless extension repeaters be designed to hide? How to set up the TP-LINK brand?
Setting method: there are two ways to set up, one is through the WPS one button setting, one is if there is no WPS key, enter the interface debugging.
Q:Is intelligent access control available offline?
1. supply voltage: the use of DC 12V-24V + 10%/2A single supply operation, operating current <100mA (excluding electricity plus electricity driven).2. working environment: temperature: 20~+60 relative humidity: less than or equal to 95% DEG C3. optional password keyboard input.4. can manage 100 thousand user card, offline can store 3000 open records, can store up to 2000 black list, storage records in power down, can guarantee 10 years is not lost.5. contactless IC card read and write time: less than 0.2S.6. contactless IC card read and write distance: 10~100mm, IC Keychain caillaux reduced7. network communication interface: RS485 (standard).8. communication transmission distance: 1.2Km (standard), long-distance communication network.9. appearance size: host L95 * W70 * H25mm.10. scope: attendance, access control, online patrol.
Q:How many repeaters can Ethernet use at most?
As a result of loss, the signal power transmitted on the line will be gradually attenuated, attenuation to a certain extent will cause signal distortion, and this will lead to a reception error. Repeaters are designed to solve this problem. It completes the connection of the physical circuit, amplifies the attenuated signal and remains the same as the original data. In general, both ends of the repeater are connected to the same media, but some repeaters can also do the switching of different media. Some brands of repeaters can connect cable segments of different physical media, such as thin coax cables and fiber optic cables
Q:How to use a wireless repeater and wireless network card to make desktop computers online?
Network wireless repeater narrow said wireless AP, AP Access Point (wireless access node) abbreviation, it is equivalent to the wired network hub or switch, however, this is a wireless signal transmission function of the hub, it can be for a plurality of wireless Internet equipment to provide a dialogue meeting point.
