WiFi Fault Finding & ConsultancyRead More
Diagnose issues with network traffic and network capabilities and the suitability of any existing infrastructure.
It's important to ensure your vital services run without any issues, so we design your network from the ground up with this in mind.
We will inspect and test your existing infrastructure to ensure it is fit for purpose and scalable for your business needs.
One of the most important aspects is ensuring you can connect when and where you need to!
Performance Networks experienced engineers will attend site and perform a wireless survey or network analysis and WiFi audit. This will identify any potential sources of interference and specific venue obstacles which would hinder or are hindering WiFi coverage. The survey/analysis looks all aspects of the building and network and incorporates a full spectrum analysis to pick up any other devices working within similar frequencies.
The engineer will also check the type of internet connection currently used onsite as this plays a major role in the WiFi experience. Once the survey or analysis is complete the engineer will compile a report with their findings and the required works to provide strong coverage and throughput.
As our site surveys consider everything from your premises size, network capacity, construction and types of device connecting to the network. Whether it be high network congestion, building material or local interference which could affect signal levels our engineers will take this into account when designing or fault-finding the network.
We therefore guarantee coverage to pre-defined signal levels to ensure even the smallest of devices like phones or handheld devices, if the network is installed to the specifications detailed in our survey report.
Our engineers can advise on the equipment type and optimisation to give quality of service to any application. We have a wealth of experience building and maintaining high performance networks and can provide consultancy on Cisco, Ruckus, Meru, Xirrus, Aruba, Ubiquiti and many more. Whatever your network requirements Performance Networks will help design of fix a network that will both meet and exceed your needs.
We are experts in working with latency sensitive applications like VoIP and video and consult on prioritisation and network topology.
What can you expect in a wireless site survey?
CAD drawings are preferred (but not essential) as the wireless site survey software can use the layers on import to set the different floor and wall materials, and giving the attenuation properties of each.
A scale is also usually provided here, which means you will receive an accurate heatmap. We also support use of PDF, BMP, JPG, JPEG, PNG, GIF and SVG files. When CADs files cannot be supplied, then we will need to define these properties manually.
Once the scale is set correctly we can then define the differing wall and floor types. This is very important to ensure the WiFi design uses a 3D model of the whole building, and not just each floor individually. A 3D model means the software considers interference from the Access Points (APs) on all floors - which creates the optimal plan. Get in touch if you need more help with building plans.
So once onsite, the engineer will setup the wireless survey kit in accordance with the building type. This could be anything from standard office, factory, warehouse, or laboratory environment. The building could be single or multiple floors. During a fault-finding WiFi survey, the engineer will again discuss any main issues being experienced with the site contact.
The engineer will then document the location of a Comms Cabinet and the equipment within (such as switches, firewalls and Internet router). Also, they will confirm the type of cabling if possible – is it CAT5/5e/6/6a? If possible they will also note the physical location of the wireless Access Points (APs) in use. During this walk of the building they will also be checking out any potential problem areas or safety issues.
Generally, the first task will be to walk the building checking out any potential problem areas or safety issues. Once complete the engineer will walk the building using the spectrum analysis tool, recording the data as they go. This stage should show any possible sources of interference from WiFi or non-WiFi devices. Next is the main WiFi site survey. The engineer will place the APs in the correct locations using the Tripod. This could be vertically mounted near a wall, or horizontally next to the ceiling - Which benefits from the way the most antennas are aligned in modern indoor Access points. Using the Ekahau software they will walk the area taking readings. When they get to the edge of the coverage area for that AP, they will then “freeze” the software and move the AP to the next location.
This is repeated until the entire building or location has been completed. The coverage area size will be determined by the type of WiFi network that is required, which will have been ascertained during step 1. One NIC(Network Interface Card) will be used to perform a passive wireless survey, where the laptop and software just “listens” to the signals. Another NIC will perform an active WiFi survey, where data is sent to test connectivity (PING) and optionally throughput (using Iperf). Extra NICs can be added to speed up the passive survey. The extra NICs then listen to different parts of the spectrum, so sharing the load. Once complete, the engineer will then summarise the initial findings with the onsite contact.
In the case of a fault-finding wireless site survey the report will also include recommendations on what is required to improve the network. If any clarification is required upon receipt the WiFi survey report, then our engineers will be more than happy to go through it with you.
*If you have received a predictive, or pre-deployment wireless survey, then a follow up post install WiFi/RF (Radio Frequency) site survey is always recommended to verify the WiFi network is working effectively*
*If you would like to see an example of a report showing what is covered, then please contact us.*
*A follow up post install WiFi/RF (Radio Frequency) site survey is always recommended to verify the WiFi network is working effectively*
Performance Networks offers three types of WiFi survey: predictive model WiFi survey, a pre-deployment onsite WiFi survey or the post-deployment or fault-finding WiFi survey. Each type of survey differs according to the site or your specific requirements.
The predictive model WiFi survey differs from the other types as it is essentially a virtual survey.
It relies upon high quality building plans to enable us to properly assess the requirements. Working with CAD drawings of the building plans we’ll use sophisticated software to build up a 3D model, set the different floor and wall materials, and so on, to provide an accurate virtual picture of your site. The benefits of a predictive model WiFi survey are that it provides a quick, cost-effective and practical estimate of your site’s requirements, which causes minimal disruption to your business activities. However, it can’t account for onsite issues such as cabling paths, or local interference sources.
Though the predictive model WiFi survey can give a reliable estimate of your site’s requirements, the pre-deployment WiFi Survey is based onsite in order to give a comprehensive understanding of your site’s requirements.
One of our engineers will visit your site to conduct what’s known as an AP(Access Point)-on-a-stick survey. Our engineer will bring a range of sophisticated equipment including an AP attached to a tripod, which is connected to a power source. This then allows the engineer to position the AP correctly before taking measurements to determine the wireless coverage area, signal strengths and anything else that may interfere with the WiFi signal.
The post-deployment or fault-finding WiFi survey is conducted on sites where a wireless network has already been installed (whether by us or anyone else).
This type of quality-checking survey is usually required when the client has noticed specific issues on site. These issues could include voice-over WiFi (VoWiFi), video calls, deadspots or plain old throughput issues. Our engineers will visit your site and use sophisticated equipment to check that your wireless network is functioning as it was meant to. We recommend this type of WiFi survey as “health check” at regular intervals, in order to prevent any long-term issues with your wireless signal or network.
