Compare Ethernet to wireless adapters and access points by port speed, bands, antennas, security, and bridge behavior, then choose 20 MHz or 40 MHz using interference and throughput tests.

Use a Wi-Fi-to-LAN adapter to connect Ethernet equipment over a long-range outdoor Wi-Fi link. Compare 20 MHz vs. 40 MHz channels, antennas, path clearance, power, and testing.

RSSI signal strength explained: learn what the reading means, how WLAN, WPAN, WWAN, mesh, and point-to-point networks differ, and how noise, SNR, and link rate affect decisions.

Compare LTE Band 20 and Band 71 frequency pairs, FDD operation, regional device support, and propagation context, then convert milliwatts to dBm with worked examples.

4G LTE frequency explained: compare Band 2 LTE and Band 4 LTE by uplink, downlink, FDD pairing, propagation, regional use, device support, and service checks.

Wi-Fi 802.11 b/g/n and BGN mode mean older 2.4 GHz compatibility, slower mixed-mode behavior, and different extension choices. Learn when to use a range extender or access point.

LTE Band 4 uses 1710–1755 MHz uplink and 2110–2155 MHz downlink. Learn what frequencies 4G networks use and why cellular and Wi-Fi coverage depend on power, antennas, obstacles, and network design.

Compare LTE Band 14 with Band 3 and Band 30 by paired uplink and downlink frequencies, FDD or TDD duplexing, propagation, bandwidth, regional use, device support, and network access.

dB to mW is not a direct conversion: plain dB is a ratio. Learn dBm to milliwatts and dBW to watts formulas, negative, zero, positive examples, reverse conversions, and the 30 dB offset.

Cell phone communication follows a call or data session from handset to radio access, core network, and outside services. Compare cellular network types and convert dBm to mW for clearer RF readings.
