If more coverage than a 2-pack is needed, the router’s 2nd Multi-Gig port can host aMulti-Gig switchto increase the number of supported satellites. Alternatively, you can use satellites with two or more Multi-Gig ports and daisy-chain the units. Entry-level Multi-Gig (2.5Gbps) wired b...
The input voltage is the voltage of the AC power source that you want to convert to DC. In our case, we want to convert 120V AC to 12V DC. Step 2: Choose the AC to DC Converter Choose the appropriate AC to DC converter based on your requirements. For our case, we will use a tr...

to open up the UHF spectrum range of 952–954 MHz for RFID use. High-powered passive tag systems can use an antenna power between 10 mW to 1 W and an antenna gain of 6 dBi, which gives maximum power equivalent to 4 W EIRP. Users must obtain a license to use this RFID system. ...
After you've connected the 4g lte wifi modem to a network outlet, connect the 4g lte wifi modem to power, and then press the power switch (if present). Wait a minute or two for the 4g lte wifi modem to fully boot up. At this point the modem's power light will be on, but the...
Use the free-space loss model to calculate signal loss. The loss in a 6.5 m radius is about 56.5 dB. Signals need to penetrate a wall, which brings approximate 25 dB loss. The required field strength in the major coverage is -65 dBm. The antenna gain is 2 dBi. Therefore, the transmi...
If you have data from an existing ZendDBi installation, it can be migrated. You first want to export theolddatabase usingmysqldump. This will dump out the database into SQL DDL/DML. You’ll probably want to use the database’srootaccount to run this command, for it has permission to ...
