  • What is Wireless Repeater (FBelec)?


    Wireless repeater, in a wide space environment, the coverage of wireless signal is more important than bandwidth and speed. Undoubtedly, it is a better choice to use repeaters to expand the coverage of base stations. In the network, wireless repeater can be simply and narrowly referred to as wireless APWi-Fi Range Extender

    AP is the abbreviation of access point (wireless access node). It is equivalent to the hub or switch in wired network. However, it is a hub with wireless signal transmission function. It can provide a conversation intersection for multiple wireless Internet devices.

    Introduction to relay technology,Universal Wireless WiFi Range Extender

    It is feasible to expand the scope of 802.11 network by using repeater technology. In fact, the IEEE 802.11 protocol has clearly defined several modes to support relay. For example, a wireless distributed system (WDS) allows an access point not only to connect with another access point on a wireless link, but also to provide services for 802.11 devices at the same time. If the bandwidth has little to do with the application, it has the greatest flexibility if 802.11b is used to expand the range. If the serving user and two-way transmission are using the same wireless communication channel, the available bandwidth has been substantially reduced by half.

    AP is the abbreviation of access point (wireless access node). It is equivalent to the hub or switch in wired network. However, it is a hub with wireless signal transmission function. It can provide a conversation intersection for multiple wireless Internet devices. Wireless AP is a name with a wide meaning. It not only includes a simple wireless access point (wireless AP), but also a general term for wireless routers and other devices. However, in order to distinguish these two types of devices, we generally call devices with AP function as wireless AP and APS with router function as wireless router.

    Simply put, AP is the extension line, repeater and amplifier in wireless network. Play a role in strengthening the signal and extending the distance.

    In order to better understand the word, I separate it instead of using the professional term AP.Wi-Fi amplifiers

    Under what circumstances is bandwidth distortion? Wi-Fi boosters?

    The repeater can expand the coverage of 802.11 network, but we should pay attention to several problems. One thing to note is that the repeater must receive and forward frames on the same channel, which means that your bandwidth is actually divided into two halves. Although range is more important than bandwidth, the transmission rate of long-distance clients will be as low as 1Mbps. Due to the overhead of 802.11, only about half of the bandwidth can be used for data transmission. Because of the repeater, the bandwidth is divided into two halves again, especially when multiple users share the same channel, so you will encounter the problem of bandwidth.

    Another problem to note is that some repeaters have only one omni-directional antenna, while some access points (which can enter repeater mode) have two antenna diversity. If you want to use a higher gain antenna to expand the range, use a multi-channel omni-directional antenna instead of a directional antenna anyway. When using the diversity antenna system, only one antenna can work at a time. Therefore, when the transmission is busy, it will not transmit in the opposite direction, resulting in interference and retransmission problems. Generally speaking, the effect of using multi-channel repeaters is not good. In short, the longer the wireless path, the higher the probability of failure.

    As for which 802.11 standard is most suitable, even if the 802.11a frequency spectrum has fewer congestion problems than 802.11b/g, I also consider 802.11b/g because it has longer transmission distance, more fierce market competition and more equipment choices.

    Selection of outdoor products,signal booster

    Products to be paid attention to when selecting outdoor relay system include:

    Bidirectional outdoor amplifiers - these products generally include a low-noise preamplifier receiver and a power amplifier for transmitting data. Bidirectional amplifier can greatly increase the coverage and performance of outdoor operation link.

    Built in directional antenna - by deploying a system with a built-in directional antenna, you can better aim at the area you want to cover while limiting unwanted RF overflow.

    Optimized 802.11 MAC system - systems that support 802.11 MAC layer services optimized for outdoor use can provide better overall performance. The original 802.11 standard is optimized for indoor systems. Users should seek an 802.11 MAC system optimized for outdoor links. Optimization measures include the adjustment of MAC services, such as supporting long-time RF links and request / cancellation transmission (RTS / CTS) by extending the ACK connection timeout.

    Outdoor enclosure components - the enclosure of the system components must be able to withstand greater temperature changes so that the system will not fail due to bad weather conditions.

    An excellent WLAN system shall be able to provide all the above outdoor related features and provide dynamic RF intelligence and centralized strategy management. FBelec Wireless Range Extender is best brand.
