How Far will my Wi-Fi Signal Reach
The Wi-Fi Signal range of computer network totally depends on Type of network and access points used while building up the network.
Simple LAN network used in houses may have a single wireless access point that covers the house completely while business organizations may have distributed the network in Zones in order to cover large office building. The cost of building large network is directly proportional to the area of building or organization.
The type of wireless Access Points/ Routers used in the network will be determining the range of Wi-Fi Signal of the network. Some factors that affect Wi-Fi signal
- Physical Obstructions
- Network Range & Distance between Devices
- Wireless Network Interference
- Signal Sharing
- Network Usage & Load
- Poorly Deployed Antennas
- Local Environment Characteristics
- Spectrum Channel Limitations
- Signal Reflection
- Wireless Signal Restriction
- Transmitter Power Limitations
- Backwards Compatibility with Older Standards
- Polarization of Signal
- Speed Loss Due to Wireless Overheads
- Lowering Performance to Stay Connected
The Wi-Fi signal range of any given access point also varies significantly from device to devices. Factors that determine the range of one access point include:
- Protocol used by network
- Signal strength of the routers
- Obstructions Caused by Infrastructure i.e. Walls or room separating sheets.
- the specific 802.11 protocol it runs
- the strength of its device transmitter
- the nature of physical obstructions and/or radio interference in the surrounding area
In a home network wi-fi with band width of 2.4GHz reach up to 120-150 Feet (Indoor) and 250-280Feet (outdoor). Previous Versions of Wifi Band width can reach up to one third of current figures. Walls made of Bricks and Metal Rods reduces the range of wi-fi adversely . So the range given above may vary from place to place as per the surroundings. Wifi Ranges of large Band width are affected more than small ones because of these physical obstructions.
Electronic Gadgets used in houses also affect signal strength. Radio signals from these devices obstruct Wi-Fi Signal, causing reduction of Wi-Fi strength in the house. Electronic Gadgets with similar frequencies negatively affects Wi-Fi range.
Finally, Antenna Orientation of transmitter strengthens or reduces Wi-Fi ranges over particular area of the house. Many Wi-Fi routers are introduced in the market with more than one antenna. Adjusting these antennas help in covering larger range of a building. The Smartphones or Access points that are in placed in direction of antenna receives more signal strength than those in the opposite direction.
There are a variety of routers available on the market. Below are my picks for some of the best sellers, and they all can be purchased :
