Frequently Asked Questions

Are Predictive Wi-Fi Site Surveys accurate?

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

Why do I need to have an On-Site Survey?

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.

Why should I upgrade my Wi-Fi from 802.11n to 802.11ac?

In today’s wireless environment, there is a great volume of devices increasing the demand on networks,
especially with the emergence of IOT (Internet of Things).

• 802.11ac provides maximum capacity and speed.
• 802.11ac is incredibly fast and designed for the 5ghz band.
• 802.11ac utilises Multi-User technique, Multiple In Multiple Out (MU MIMO) (Simultaneously they are able to communicate to multiple users at the same time).
• In high density environments 802.11ac will improve throughput and efficiency.

How should my Access Points be mounted for optimum coverage?

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.

My existing Wireless Network is congested and experiencing latency. What should I do?

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.

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

How can I secure my Wireless Network and optimise for Mobile Devices at the same time?

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.
