We know wireless

When designing a wireless network it is of high importance to understand the environment of the coverage area. Detailed requirement specifications should be documented including the desired goals of the wireless communication.

Questions or specifications to be analyzed at an early stage are.

- Is the coverage area indoors or outdoors?

- What kind of building materials are used in the vicinity, and how thick are the walls?

- What kind of goods are stored in the area, and how will the storage environment change from day to day?

A detailed analysis of gathered information will apoint to the right set of hardware and system configuration, to assure a robust and fail proof network design. Bellow you will find our 4 stage philosophy on how to design and implement a fail proof wireless network.

1. Planning & Site Analysis

Before live physical wifi testing is done, a theoretical assessment based on drawings of the premises is essential.

With these drawings we will generate a theoretical coverage map including data rate in different parts of the network area. The amount of access points and careful frequency channel planning is an important part of the design process. Access points must not interfere with each other, be installed too far apart, or be too high of a quantity.

When the theoretical planning phase has reached a satisfied stage, the next phase is to test and measure the planned coverage. Collection of data and analytics are done on-site and will create a base for architecture re-design and modification. This data can be created by using temporary access points and client simulation.

Detailed documentation will be created with the results of how to achieve optimal coverage and stability. During this phase we will do an analysis of possible interfering sources such as neighboring wifi networks or other broadcasting devices nearby.

Repeated site analysis of this kind are recommended with set intervals to maintain a healthy wifi architecture and to detect new possible problem areas.

2. Hardware

Choosing the correctly intended hardware is important when designing and building a wireless network. Network controllers, access points, communication frequency and antennas must be carefully chosen for an optimal match. Factors such as capacity/bandwidth, coverage area and how the wireless network communicate and interacts with other networks, are all important in the choosing of ideal hardware and optimal configuration.

3. Installation

Once satisfied with stage 1 and 2, the next phase is installation, setup and configuration of the equipment. We can provide these services or cooperate with local electricians for services such as electrical wiring and mounting.

Once installed the firmware must be carefully updated and configured to meet requirements in stage 1 and 2.

4. Continuous operations & health monitoring

Regular diagnostics and monitoring of the network is essential. A wireless network is not to be setup and left to work on its own. Security updates and system logging should be executed and diagnosed regularly. Preferably a remote administration toolkit is setup to keep the system up to date and to open the possibility to determine and fix possible issues within minutes. A remote toolkit will allow constant automatic monitoring to create system alerts when the network is in need of maintainance, either by remote admin or a scheduled on-site visit.

We recommend that a site analysis is done at least once a year to prevent unnecessary interruptions of the network.
