A wireless site survey, sometimes called an RF (Radio Frequency) site survey or wireless survey, is the process of planning and designing a wireless network, to provide a wireless solution that will deliver the required wireless coverage, data rates, network capacity, roaming capability and quality of service (QoS).

Cellular signal strength of -74dBm (or 66 asu) displayed on a smartphone.Also shown: signal bars of two cellular networks, and signal bars of a Wi-Fi network. In telecommunications, received signal strength indicator or received signal strength indication [1] (RSSI) is a measurement of the power present in a received radio signal.
Weak signal strength can also be caused by destructive interference of the signals from local towers in urban areas, or by the construction materials used in some buildings causing significant attenuation of signal strength. Large buildings such as warehouses, hospitals and factories often have no usable signal further than a few metres from ...
A bridge router or brouter [1] is a network device that works as a bridge and as a router. The brouter routes packets for known protocols and simply forwards all other packets as a bridge would. [2] Brouters operate at both the network layer for routable protocols and at the data link layer for non-routable protocols. As networks continue to ...
A modem and router work in tandem to deliver you an internet connection and then grant access to your various devices. Modem vs. router: The differences between the pieces of hardware that connect ...
Free-space path loss: This is the fundamental loss that occurs due to the spreading of the radio wave as it propagates through space. [2] It follows an inverse square law, meaning the signal strength decreases proportionally to the square of the distance between the transmitter and receiver.
Your router is responsible for sending Wi-Fi and plays a crucial role in network security. If it's too old or outdated, it may be time to replace it.
Conventional Internet routers and network switches operate on a best-effort basis. This equipment is less expensive, less complex and faster and thus more popular than earlier more complex technologies that provide QoS mechanisms. Ethernet optionally uses 802.1p to signal the priority of a frame.
