Yes. Wi-Fi site surveys are very reliable if conducted correctly with reputable surveying equipment. NetWireless highly skilled engineers use the most advanced software by Ekahau to conduct Predictive Site Surveys from scaled building plans.

To ensure an accurate infrastructure design, it is critical that building plans are to scale with all barriers and walls clearly mapped.

Upon completion of a Predictive Site Survey, a bill of materials and a proposal can be easily attained.

For further information on Passive, Active and Predictive site surveys please refer to: Site Survey Page

An on-site survey determines the building structure and materials. Room sizes, location of furniture, ceiling heights, and the complexity of the environment can affect your Wi-Fi connectivity and reliability.

Unlike Predictive Site Surveys, On-Site Surveys will also define how many neighbouring rogue access points are causing external interference.

This type of survey is recommended for an office environment or for businesses located in close proximity.

802.11ax also known as Wi-Fi Max or Wi-Fi 6 is upon us. The new standard has many benefits which aim to improve performance, predominantly in areas of overlapping coverage, where congestion is a serious problem. The new standard will cater for the growing IoT market with efficient allocation of low data-rate connections, improved battery life of sensors and extended Wi-Fi ranges.

Improvements include but are not limited to:

  • Enhanced operation in the 2.4Ghz and 5Ghz bands
  • Increase data rates – Average throughput per station is increased by at least 4x
  • OFDMA uplink and downlink – By dividing a transmission across a frequency dimension, with pairs of devices transmitting and receiving in sub channels known as Resource Units (RU’s), an access point can bundle several frames together in different sub channels in a single transmit opportunity offering many additional avenues for traffic management.
  • Uplink Multi-User MIMO – The beamforming report has been reduced and client devices no longer need to be staggered to reduce interference, control protocols simultaneously allow Access Points to respond, making MUMIMO more efficient.
  • Spatial re-use creates more simultaneous transmissions by allowing a device to transmit over the top of a distant transmission rather than being forced to wait.
  • Maintain or improve power efficiency of client devices with longer sleep intervals and scheduled wake times
  • Extends the Wi-Fi signal range
  • Reduces the effects of interference
  • Backwards compatibility with 11a/b/g/n/ac
  • Indoor and outdoor network compatibility

Location, Location, Location

It is highly recommended that Access Points are located overhead with 1m of clear space surrounding each one.

If aesthetics are of concern, specially designed ceiling mounts can be supplied that do not interfere with the signal but will hide the appearance of the Access Point.

Wall mounting is an alternative option however this is dependent on application. Avoid front and/or rear wall mounting as shadows can be problematic.

If a connection is congested or saturated it means it is performing at maximum capacity, any further traffic will cause latency. You may experience drastic drops in your network, unacceptable packet delays and session disruptions causing jittered screens.

Congestion can be caused by too many clients attaching to a single Access Point, large downloads being undertaken by several people at the expense of others, external interference from other noise sources or other access points on the same channel. Latency can also be experienced due to hardware, server and access point locations.

Potential solution: It may simply be your network requires optimisation. In more complex situations, It could mean your network needs redesigning, underpowered equipment replaced or it could be time to upgrade the link speeds.

Site Survey to audit your wireless network is advised (including a spectrum analysis) to identify latency issues.

Mobile devices connecting to wireless networks has seen unprecedented growth over the last decade.
Having the correct wireless design is critical. Design your network to be 802.1x compliant and use a radius server with a multi-factor authentication to provide high security.
