Enterprise Wireless & W-iFi Design - Grandmetric IT Services

Enterprise Wireless

Our Wi-Fi design service include full scope of the enterprise wireless system design from planning and configuring of the network through the optimization and troubleshooting tasks. We can also train your team on all those aspects using our dedicated Enterprise Wireless Advanced course.

Wi-Fi Design: Network Planning & Site Survey

We visit your locations to do site survey and provide detailed plan with analysis of the AP location and antenna guidelines.

Detailed Network Design and Configuration

For the network design and configuration we use enterprise class equipment and controllers.

Wi-Fi Measurements, Troubleshooting and Optimization of Radio, Security and Network Aspects

For troubleshooting and optimization tasks, we dive into the spectral analysis, controller settings, security issues and network configuration to get the overall picture of the network from different angles.

Enterprise Wireless Advanced Training

The dedicated course on Wi-Fi systems goes through the radio systems theory, Wi-Fi standards and operation, configuring security features (e.g., ISE, 802.1x, Guest Access) and planning and optimization practices.

Case Study: Wi-Fi Site Survey

Project name: Wi-Fi Audit

Client:
Global eCommerce company

Implemented services:
Technical Consulting, Wireless Site Survey, Audit

Engagement:
Two wireless engineers

Problem:
Customer was experiencing poor Wi-Fi performance in three offices at various European locations. The issues included: low data-rates, connection drops, low video-calls quality, problems with accessing Wi-Fi network, missing Access-Points (AP).

Solution:
After the initial contact from the customer, who detailed us with the problem, we proposed to conduct a thorough audit of the Wi-Fi network to verify: performance, installation and configuration of the current setup. Based on the current situation and found issues, the target was to provide a list of suggested improvements.

The audit was divided onto three parts:

Service preparation (1 day, remote):
1. Q&A with the customer’s IT operations manager at each location to gather information on the particular issues experienced by the end-users.
2. Audit of the wireless controller to collect information on the setup, configuration, and issues.
On-site service (1 day, on-site):
1. Site survey with active (throughput, delay) and passive (coverage, SNR, channel overlap) measurements.
2. On-site AP mounting and location verification.
3. Live performance troubleshooting in the wireless controller.
Audit summary part (2 days, remote):
1. Analyzing all the information and report preparation which included found issues and suggestions for improvements.
2. Planning of the new AP location.

Facts:

Audit for each of the location took 4 days.
Each of the Wi-Fi network at the customer’s site had 30+ APs and served 200+ users.
Some of the found issues included:
- bad mounting of some APs,
- not-optimal AP location,
- using 2.4 GHz for dense-network,
- too low number of APs in areas where there are a lot of users,
- wrongly configured radio resource management algorithms,
- too high transmit power for APs.
Some of the suggested improvements included:
- switching-off 2.4 GHz band, and use it only where/when needed;
- changing the location of the APs – move them to central locations and close to where the users are;
- changing mounting of the APs – to decrease disturbance from the metal elements;
- decreasing transmit power – to decrease overshooting;
- using dedicated APs for conference rooms and separate for open spaces;
- decreasing the number of SSIDs to the minimum – to save the “air-time”.

Effects:
Customer’s IT team changed AP location according to new plan, corrected mounting of the APs, adjusted wireless parameters (like bandwidth, transmit power available channels), and tuned radio-resource management algorithms. The performance of the network was improved: lower call-drop rates, higher data-rates per end-user, higher quality of the video calls calls.
