Showing the Garmin ga27c GPS antenna, we can see a piece of ceramic patch on its PCB board:Garmin GA-27 active

interference If the noise intensity of your network bandwidth exceeds the -85DBM, then RF interference is likely to impair network performance. In this case, the user's retry rate will exceed 10%, and the user will feel the network speed is affected. This can happen, for example, when a wireless user is in the same room as a running microwave oven. If you decide that the problem is caused by radio frequency interference, you have to find out where the interference comes from and try to remove

present, wireless routers in the indoor launch power generally does not exceed 20dBm. The higher the transmitting power of the wireless router, the higher the signal strength, but more than the specified range will cause large electromagnetic radiation and interference. Antenna gain: The greater the gain, the stronger the signal strength, at present, most of our routers antenna gain 3dBi. Working Band: T

router until you hear a "click" of a network card. Now that the "one wireless router" and "one broadband network cable" have been successfully connected, the process of installing the wireless router has already been completed, and then let us know about the wireless router. In addition to what we have just mentioned, wireless router, a number of network cable interface, a wireless router also has a power interface, as a network equipment, wireless routers need independent power supply, that i

When the router is published, there are some technical terms, such as 802.11AC, 5G, gigabit, dual frequency, 2*2 antenna, Wi-Fi, and also the conclusion that "10 times times Faster", "Top Configuration", "Global X". Under the manufacturer propaganda, some people think that the product is good to be bad, also some people think the manufacturer is bragging x. This article is the wireless router knowledge popularization, each followed by a selection of s

wireless route, it will also seriously affect the transmission of wireless signals. 6. Adjust the antenna Angle During use, the antenna angle is also worth our attention. Through the adjustment of the antenna angle, we can think of the enhancement of the coverage intensity of wireless networks in some areas, enhances the stability and transmission rate of the sp

erection cost is not as high as that of wired LAN, the successfully deployed wireless LAN can be easily changed in the future. More importantly, the expansion of the wireless LAN network is very good. For example, it can be compatible with various network connection interface standards, supports and complies with all communication protocol standards. For common access users, it is almost a completely transparent link that can meet the access needs of various client systems. With the help of Wir

Wireless LAN technology is becoming more and more mature, but many people are not clear about the wireless LAN networking method. Here we will summarize some specific methods for you to learn. Wireless Networking 1 wireless networking Networking requirements: Establish a network without a line in the LAN to share resources among devices. Networking Mode: place a wireless access point in the LAN center and add a wireless network card to the Internet device. 2-point-to-point wireless networking ①

There are many networking methods for wireless networks. which method is suitable for our work environment? Here we will give a detailed description of the networking requirements. Many of us are not clear about the typical networking methods of Wireless LAN, But what operations should we do? The following describes several typical methods. I believe this article will be helpful to you. Wireless Networking 1 wireless networking Networking requirements: Establish a network without a line in the L

occur, reducing its transmission range. Therefore, do not hide a wireless router in the corner of the room, or bury it in the basement or in the shelve, instead, try to place the wireless router in the center of your wireless activity. For the duplex room, try to place the wireless router in the center of the room So how can we identify such a central location? In fact, the simplest way is to observe through your line of sight, that is, where you can see the most room scenarios, then this
