,,,here you can find some schemes of WiFi amplifiers...https://vrtp.ru/index.php?act=categories&article=3393&CODE=article ,,,and another 2.4 GHz amplifier scheme...

The only major drawback of the TL-MR3020 is the lack of an external antenna connector, this however can be easily hacked in a couple of simple steps and takes less than 15 minutes. Option A: If you want to use a Pigtail: Solder the center of RG-174 (or the like) coax cable to the left pad (connected to C43 - see Image) and the braid/shield of the coax to the right strip (GND). Option B: If you want to use a PCB Edge RP-SMA connector: Solder the center pin (round) to the left pad (connected to C43 - see Image) and the right pin of the connector to the right pad (GND). There have been reports of EM related damage to MR3020 routers that have been hacked the way shown below. It seems that the cut off capacitors after J4 were put there for EM protection rather than matching the antenna. Please follow the method shown above to have proper EM protection for your router's external antenna. The following images are only left as a reference for now

Antenna BDM-2 is designed for outdoor use, although often applied in residential/non-residential premises. Experts recommend the use of antenna BDM-2, as a client equipment in all cases, build wireless networks of small and medium-range. The original of the antenna is with a 64mm diameter cylindrical vibrator

This is my oldest yagi-patch antenna project which I will try to optimize on the 2.442GHz frequency

Ethernet and wireless networks each have advantages and disadvantages; depending on your needs, one may serve you better than the other. Wired networks provide users with plenty of security and the ability to move lots of data very quickly. Wired networks are typically faster than wireless networks, and they can be very affordable. However, the cost of Ethernet cable can add up -- the more computers on your network and the farther apart they are, the more expensive your network will be. In addition, unless you're building a new house and installing Ethernet cable in the walls, you'll be able to see the cables running from place to place around your home, and wires can greatly limit your mobility. A laptop owner, for example, won't be able to move around easily if his computer is tethered to the wall. There are three basic systems people use to set up wired networks. An Ethernet system uses either a twisted copper-pair or coaxial-based transport system. The most commonly used cable for Ethernet is a category 5 unshielded twisted pair (UTP) cable -- it's useful for businesses who want to connect several devices together, such as computers and printers, but it's bulky and expensive, making it less practical for home use. A phone line, on the other hand, simply uses existing phone wiring found in most homes, and can provide fast services such as DSL. Finally, broadband systems provide cable Internet and use the same type of coaxial cable that gives us cable television. If you plan to connect only two computers, all you'll need is a network interface card (NIC) in each computer and a cable to run between them. If you want to connect several computers or other devices, you'll need an additional piece of equipment: an Ethernet router. You'll also need a cable to connect each computer or device to the router. Once you have all of your equipment, all you need to do is install it and configure your computers so they can talk to one another. Exactly what you need to do depends on the type of network and your existing hardware. For example, if your computers came with network cards already installed, all you'll need to do is buy a router and cables and configure your computers to use them. Regardless of which type you select, the routers, adapters and other hardware you buy should come with complete setup instructions. The steps you'll need to take to configure your computers will also vary based on your hardware and your operating system. User manuals usually provide the necessary information, and Web sites dedicated to specific operating systems often have helpful tips on getting several different computers to talk to each other. Next, we'll examine the advantages and disadvantages of wireless networks. Nervous about Networking? Most people who have a basic familiarity with computers can set up a network without much help. But the idea of installing cards and making connections makes some people nervous. Many Internet service providers (ISPs) offer home networking packages. For a monthly fee (and sometimes an initial setup cost), the ISP will provide you with the hardware and support you need to build and maintain your network. The easiest, least expensive way to connect the computers in your home is to use a wireless network, which uses radio waves instead of wires. The absence of physical wires makes this kind of network very flexible. For example, you can move a laptop from room to room without fiddling with network cables and without losing your connection. The downside is that wireless connections are generally slower than Ethernet connections and they are less secure unless you take measures to protect your network. If you want to build a wireless network, you'll need a wireless router. Signals from a wireless router extend about 100 feet (30.5 meters) in all directions, but walls can interrupt the signal. Depending on the size and shape of your home and the range of the router, you may need to purchase a range extender or repeater to get enough coverage.

Can you guess what's inside it?

The modems have LTE parameters LTE connection. To determine the quality of the signal, note the following fields: — Signal strength — RSRP — RSRQ — SINR — CQI The following table shows the different values of these parameters, which correspond to very poor (Cell Edge), bad (Mid Cell), good (good) and very good (Excellent) the signal quality of the LTE: Next, briefly explain each parameter, which determines the quality of the LTE signal. The power of the signal The signal power shows the level of the received modem signal LTE. These values correspond to the readings of RSSI (Received Signal Strength Indication) of the LTE connection. The value is measured in dBm (dBm). Usually routers have indicators if it means burning the maximum -90 dBm or higher (tends to zero). If any indicator is not lit, then the signal level is insufficient for the connection to the LTE network. When the values of RSRP= -120 dBm and below, the LTE connection may be unstable or not installed. RSRP RSRP (Reference Signal Received Power) is the average value of the power taken by the pilot signal (Reference Signal) or the level of the received signal from the Base Station(BS) The RSRP value is measured in dBm (dBm). The signal strength of the LTE modem can also be defined using the SIGNAL STRENGTH indicators on the top panel of the device. The maximum level correspond to three burning indicator. If any indicator is not lit, then the signal level is insufficient for the connection to the LTE network. When the values of RSRP= -120 dBm and below, the LTE connection may be unstable or not installed. RSRQ RSRQ (Reference Signal Received Quality) determines the quality of received pilot signals. The value of RSRQ is measured in dB (dB). SINR SINR (Signal to Interference + Noise Ratio), also known as CINR (Carrier to Interference + Noise Ratio) – the ratio of the level of useful signal to noise level (or signal/noise). The value of SINR is measured in dB (dB). It's simple: the higher the value, the better the signal quality. When the values of SINR below 0, the connection speed will be very low, because this means that the received signal noise more than the useful part, while the probability of loss of the LTE connection also exists. CQI CQI (Channel Quality Indicator) For each subscriber station UE (User Equipment) and each frequency carrier block formed quality indicators channel CQI (Channel Quality Indicator). Depending on the required for UE speed data transmission the base station, the decision on the number of resource blocks allocated to a particular user, and what frequency blocks to allocate to the user depends on the indicator CQI. Users are allocated to those resource blocks that have the highest CQI, and therefore, the best ratio signal/noise. This parameter can take values from 0 to 15. The higher the value, the better (the higher the speed that can be allocated by the base station operator LTE). The most important first column — the value of RSRP. For example, we got to the target BS, the average is about -90 dBi. When determining the direction on the BS used a Yagi antenna with gain (KU) 12 dBi. Antenna cable, length 5 m "eats" on the attenuation of about 1.5 dBi, add about the same number of losses at the connectors — a total of 3 dBi. Accordingly, the default level of the signal at this location: -90 - 12 + 2x1. 5 = -99 dBi. As a result of the installation of the new antenna, we need guaranteed to get at least the second row of the table, in the interval from -90 to -80. Ideally, more than -80, the first line. If we keep the same cable, you need a antenna with KU at least 18dBi, better 20dBi (don't forget about the weather and the natural "swimming" signal). The output will be if not the first row, then close to it: -99 + 20 — 2x1. 5 = -82 dBi. The result can be considered very good: provided that the indicators RSRQ and RSRP SINR vary in proportion to (and usually do), we "pull out" of the connectome at least 80% of what he can give. Assume that the maximum supported rate on the BS 30 Mbit/s. Received 30 * 0,8 = 24 Mbps. We are interested in two parameters: RSSI (Received Signal Strength Indication) level of the received modem signal. This is the main "honest" indicator of the level. Is measured on a logarithmic scale in dBm. Other parameters from tables such as RSCP, RSRQ, RSRP, CQI — are service. They usually correlate with RSSI, so they shouldn't be ignored. The second, not less important parameter, especially in dense areas – the ratio signal/noise. Denoted for 3G: ECIO (Ec/Io) or Ec/No; 4G: SINR (Signal to Interference / Noise Ratio) or CINR (Carrier to Interference / Noise Ratio). Is measured on a logarithmic scale in dB. Ec/Io is a measure of signal/noise, but very tricky. Compared to conventional SINR indicator (which is used in LTE) of Ec/Io deducted natural noise. Indicator Ec/Io = 0 dB is the level when in addition to natural thermal noise nothing. Any interference of artificial origin reduce Ec/Io. (from their own neighboring BS in the first place, this effect operators is called "cell respiration" - on the border between the cells preventing the signal level from another cell of the same operator becomes significant, and in spite of a strong total signal prevent set high speed) As Ec/Io, Eb/No, SINR, and so this is all adaptive indicators. Because the link can't work with poor Ec/Io (Eb/No), then the weak signal to improve Ec/Io of BS and the subscriber agree to lower the bandwidth: used less than RB (resource blocks) and a lower modulation scheme (QAM64 - QAM16 - QAM8 - QPSK - BPSK) Therefore, by itself, the Ec/Io does not show good signal or bad (in pulsometro this figure is NOT used). It shows the contribution of artificial noise (reflection, alien sector, industrial noise) Need to watch it paired with RSCP. RCSP of these 3 the most objective indicator is the amount of energy per 1 resource block (in LTE) or channel (in 3G) is the Received Signal Code Power (RSCP). RSCP that is used to parcometre. Also it is based on the RSCP telephone/modem decides which of the cells to connect.

Triton_Mgn says,,, Good afternoon, give the antenna a good antenna for the 1800 MHz mimo Found 2 antennas on the forum: 1 - http://www.lan23.ru/forum/showthread.php?t=12671 But, unfortunately, not its size at the desired frequency, tell me who knows. 2 - http://www.lan23.ru/forum/showthread.php?t=10879 Could you tell me the thickness of the disc, can I use galvanized? In the drawing, the antenna of this size for the lower frequency 1747,5 pink color, and upper 1842,5 green. Why, then, in the drawing there are dimensions in blue? My answer is,, it can build a patches antenna instead of a disks, a horizontal patch antenna group (at one end of the frequency band) and the other group with vertical polarization (at the other end of the frequency band)

On August 4, 1945, Soviet school children gave a carving of the Great Seal of the United States to U.S. Ambassador Averell Harriman. It hung in the ambassador's Moscow residential office until 1952 when the State Department discovered that it was 'bugged.' The microphone hidden inside was passive and only activated when the Soviets wanted it to be. They shot radio waves from a van parked outside into the ambassador's office and could then detect the changes of the microphone's diaphragm inside the resonant cavity. When Soviets turned off the radio waves it was virtually impossible to detect the hidden 'bug.' The Soviets were able to eavesdrop on the U.S. ambassador's conversations for six years. The replica on display in the Museum was molded from the original after it came to NSA for testing. The exhibit can be opened to reveal a copy of the microphone and the resonant cavity inside. https://counterespionage.com/great-seal-bug-part-1/ https://www.cryptomuseum.com/covert/bugs/thing/
