Slow Wi-Fi connection crashes and funk holes cost daily productivity and nervous, but Jawnet IT Services has established with professional Wi-Fi Surveys, a method of Wi-Fi problems not only fixes, but from the beginning prevents.
Business customers expect today, of course, stable, fast, free Wi-Fi in your office. But the reality is often different: employees complain about slow Connections, in conference rooms, the Signal breaks up, and in some areas there is no reception. Easy to install additional Access Points, not often resolves the Problem – on the contrary, it may worsen the Situation by interference even. The Jawnet IT Services LTD therefore relies on the professional Wi-Fi Surveys, using special measuring equipment and analysis software, the actual radio coverage, identifying sources of interference and optimal Access Point placement allow.
Wi-Fi is now part of the basic equipment of each office. But between “Wi-Fi” and “Wi-Fi works reliably” is often a big difference in. Alexander Jawinski knows the Problem from a multitude of projects: “Many companies are installing Access Points to the feeling in the room layout. This almost always leads to problems.” The Jawnet IT Services LTD offers professional Wi-Fi Surveys, the precise data on the signal strength, channel utilization and interference to deliver. With this basis, Wi-Fi networks plan to actually work in any room, at full capacity, and with no dead zones. The Service is aimed specifically at business customers, who depend on reliable connectivity for productive work.
Why professional Wi-Fi Surveys are indispensable
Wi-Fi is simple: Access Point, hang up, switch on, ready. In practice, it is much more complicated. Radio waves do not behave as predictable as cable. You will be muted from walls, from metal, reflected by other radio networks, disturbed.
Especially in business environments factors that add to that difficult. Many users at the same time straining the network. Metal shelves in storage rooms to block signals. Thick concrete walls between rooms to dampen the Transmission significantly. Neighboring Wi-Fi network from other offices in the building are competing for the same radio channels.
Without a precise measurement is not possible to say where the Access Points are optimally placed should be. Too few of them lead to dead spots, too many to generate interference. Incorrectly configured transmit power exacerbated the problems instead of solving them.
A professional Wi-Fi Survey provides clarity. With special measurement devices, the actual signal strength at many points in the building are recorded. The data are visualized in Heatmaps, which show at a glance where reception is good, and where not. Sources of interference are identified, and optimal configurations can be calculated.
What exactly is a professional Wi-Fi Survey measure?
A comprehensive Wi-Fi Survey recorded the signal strength (RSSI) in all areas, the quality of the signal (SNR), the channel utilization and interference from other networks. Jawnet IT Services also measures the data transfer rates under real-world conditions and identify the physical obstacles that block the radio waves. From these data, a detailed heat maps, and specific recommendations for the optimal Access Point placement, channel selection and transmit power arise.
The different types of Wi-Fi Surveys
There are basically three types of Wi-Fi Surveys, each of which serves different purposes. The Jawnet IT Services LTD offers all three and choose need for the appropriate method, depending on the customer.
The Passive Survey gathers data on the existing Wi-Fi signals without an active connection. A technician with special measurement technology through the building, and records, which signals where arrive. This method is suitable for the analysis of existing installations or for planning new networks.
The Active Survey goes a step further and actually builds Connections to Access Points. Real data are measured transfers – how quickly a website loads, how stable is the connection remains, how fast Roaming between Access Points is? This method provides more realistic results for the actual user experience.
The Predictive Survey works without the need for on-site measurements. Based on floor plans, building materials, and planned Access Points is simulated radio coverage. This method is suitable for the planning in the not-yet-related buildings, replaced, however, no real measurements.
When to use which Survey method is useful
For new installations, Alexander Jawinski recommends a Passive Survey for the planning, followed by an Active Survey after Installation for validation. In case of problems with existing networks, an Active Survey helps to identify the specific vulnerabilities. Predictive Surveys uses the Jawnet IT Services LTD is mainly used for pre-planning, and rough cost estimates.
The schedule of a professional Wi-Fi Surveys in Jawnet IT Services
A Wi-Fi Survey project always starts with a needs analysis. How many users are to be supplied? What applications are they using? There are special requirements, such as video conferencing or VoIP telephony? This information, determine the required network capacity.
After the preparation is done. Floor plans of the building is to be procured or created. Special structural conditions surfaces are documented metal walls, Elevator shafts, large glass.
The actual measurement takes place on-site. A technician of the Jawnet IT Services LTD is systematically through the entire building, and recorded at many measuring points, the Wi-Fi signals. Depending on the size of the buildings, this can take a few hours to several days.
The collected data is then analyzed. Specialized Software created Heat Maps, the signal strength is color-coded to visualize. Green areas indicate good reception, yellow areas acceptable reception, and red areas of problem zones show.
This resulted in specific recommendations emerge:
- The number and positioning of the required Access Points
- Optimal channel selection to avoid Overlaps
- Recommended transmit power for each Access Point
- Configuration settings for optimal Roaming
- Identification of obstacles that should be removed or bypassed
These recommendations are summarized in a detailed report. Alexander Jawinski that also technically less savvy customers can understand the results.
Visualization of the measurement results
The Heatmaps, the Central tool for communication of Survey results. You overlay the basic plan, with color gradients that show the quality of the signal. At a glance will reveal where problems exist and where improvements are needed. This visual representation makes complex technical concepts to Non-engineers can understand.
Typical problems, the Wi-Fi Surveys reveal
The experience of Jawnet IT Services from a multitude of projects shows recurring problems. One of the most common to the wrong Access Point placement. Often these are simply mounted in the center of large rooms, without taking account of structural conditions.
Another common Problem channel overlaps. In Germany, there is a belt for the 2.4‑GHz-only three non-overlapping channels available. When multiple Access Points are transmitting on the same or overlapping channels, they interfere with each other.
Also due to high transmission power can cause paradoxically problems. If the Access Points to send to the strong overlap in their areas, and devices do not change in time for the next Access Point.
Interference from other devices are also frequently used. Microwaves, Bluetooth devices, and even some LED lighting may interfere with wireless signals. A professional Survey identifies sources of interference.
From analysis to implementation
The Survey is the basis, but the implementation makes all the difference. The Jawnet IT Services LTD provides not only the analysis but also the complete Installation and configuration of the optimized Wi-Fi network.
Based on the Survey results, choose suitable Access Points. Also, factors such as future scalability, manageability, and Budget are included. The Installation is then carried out exactly according to Plan – each Access Point to the optimum Position, with the right configuration.
After the Installation, a validation Survey follows. This is measured, whether the network is working as planned. Minor adjustments can be made if necessary.
For business customers, the Jawnet IT Services LTD also offers on-going Monitoring and periodic Re-Surveys. Wi-Fi environments are changing – new devices are added, neighboring networks, switch channels, structural changes of the radio propagation influence. Regular Checks to make sure that the network is working permanently to the optimum.
With this combination of precise analysis, with correct implementation and continuous support, the company ensures that business customers can rely on your Wi – Fi everywhere in the building, at any time and with the required speed.
