What is (SDN) Software-Defined Networking –

Software-Defined Networking (SDN) is a network management platform that enables smart and virtual or "programmatic" control over information. This helps the operator to manage the entire network consistently and efficiently, regardless of the communication technology.
NFV and SDN: many competitors surround the next step in network development Companies, drivers and service providers. Many of the developments in multimedia communications, the disruption of the cloud, the impact of increasing mobile usage and the continued pressure on businesses to reduce costs while maintaining a stable income are close to damaging regular sales.

To keep pace, many of these players are using SDN technology to revolutionize the design and use of the network.

SDN enables embedded behavior management software through applications using open APIs. By unlocking typical network architecture and implementing SDN control systems, users can still manage communication with its devices, no matter the complexity of subnet technology. Topic.

Sdn Technology Can Make The Difference For An Organization In Four Main Areas

1) Network Software: SDN allows the program to control the cell phone in addition to the computer to provide physical connectivity. As a result, network users can adapt to the behavior of their networks to support new services and even individuals. Using software hardware, the service gives you easy access to new and advanced services - all without complications with windows and stops.

2) Integrated Intelligence Management and Management: SDN is based on an integrated network management, which enables intelligence and control of network resources. Distribute standard communication methods. The system operates with an unambiguous state of the network. With the central management type of an SDN network, it provides the most sophisticated and sufficient bandwidth, security and protection policies - and an organization that provides a complete overview of the system. Dated.

3) Network Abstraction: the services and applications are running on SDN technology are abstracted from the underlying technologies and hardware that provide physical connectivity to the network control. Applications will interact with the network through APIs, instead of administration interfaces tightly coupled to the device.

4) Opening: SDN architectures mark the beginning of a new era of openness, allowing the interoperability of multiple suppliers and favoring a neutral ecosystem of suppliers. The opportunity comes from the SDN approach itself. Open APIs support a wide variety of applications, including cloud orchestration, OSS / BSS, SaaS and critical network applications. Also, intelligent software can control the hardware of multiple vendors with open programming interfaces, such as OpenFlow. Finally, from SDN, smart network services and applications can be run in a familiar software environment.

One of the main benefits of SDN technology is the ability of network operators to write programs that use the SDN API and give applications control over network behavior. SDN allows users to develop network-compatible applications, intelligently monitor network conditions and automatically adapt network settings as necessary.

How Much Does A Wireless Site Survey Cost For Business

Companies that use Wi-Fi in their daily operations know the importance of a corporate wireless network that works properly. If the Wi-Fi goes down or malfunctions, productivity may be affected. A faulty WiFi can be a big problem for the result of a company. More and more companies rely on wireless website search companies to diagnose and solve their problems. Perhaps your company is at this stage and is exploring the costs of searching for wireless sites. If this is the case, you will probably answer two critical questions for your management team: how much does a wireless website Indoor Survey cost and how much does a wireless website survey cost?

Any business that needs to outsource a technology management service generally faces the same problems:

Determine a fair price for the technology service they need.
Find a provider that provides the service correctly within your budget.
It is difficult to assess your options when you have limited knowledge of what you are looking for and the problems you are having. You can find dozens of companies looking for wireless websites with a simple Google search. If you dig a little further, you will notice that all of these companies offer different services at different prices. This can be quite confusing, especially since all of these companies call their services "wireless site search."

What Is A Wireless Site Survey

The first step in determining the cost of a wireless Site Survey is to understand what a wireless website survey is. A wireless website survey, also known as a WiFi website survey or RF website survey, is simply the process of planning a wireless network for a specific environment to meet your unique needs. Coverage, capacity and roaming. And quality. service and other measures that may be required

You must prepare a floor plan for the environment you plan to address — the more detailed the project, the better. The floor plan must include dimensions and all structures that may affect the spread of the wireless signal, such as elevators or stairs. The project will help the wireless site search engine identify all proposed access point locations. It also allows you to create heat maps that will enable you to understand the strength of the wireless signal in your environment.

The Research Report On Your Wireless Site Should Include The Following

  • Mounting locations
  • Description of cable trays
  • Scope of wireless network installation work
  • Controller hardware is required for management
  • Recommendations for a configuration based on unique needs
  • All necessary licenses and support
  • Efforts needed for continuous management
  • Recommended access point models (we prefer Ruckus wireless access points for their performance)

Is It Worth Doing A Search On A Wireless Website

This answer varies from company to company, but most of the time it is. If you're a small business that doesn't rely heavily on Wi-Fi for day-to-day operations, you probably don't need a Wireless Site Survey. If you are a medium to a large company with several dozen employees who use Wi-Fi every day, it is probably practical to inspect your workplace before purchasing an expensive Wi-Fi system. A small investment in this vital service can be financially beneficial. Long-term. This will avoid costly repairs that may be necessary if your WiFi system is not configured correctly. It will also be better suited for growth and expansion as your business grows.

A Wireless Site Survey Is Definitely Worth It If Your Business

  • In a location with a very crowded wireless environment, such as an office building
  • Has structures that can cause wireless signal interference such as a store
  • In a place full of many stable structures, like concrete pillars.
  • In any environment where WiFi is an essential aspect of basic operations.

Are There Different Types Of Searches On Wireless Websites

There are different types of pursuits on wireless websites and it is essential to know what type you are looking for before buying the wrong kind of service. Some wireless searches can be performed remotely using plans and thermal mapping software, while other pursuits on the site require a presence on the site and several hours to complete. There are studies on the site that will produce only a technical list for a WiFi implementation, while the more advanced studies on the website will provide a series of work for wiring and installation, as well as a level of effort for administration and administration. continuous maintenance

Let's compare two of the most common types of searches on wireless websites: predictive and active.

Predictive Searches On Wireless Websites

In a predictive location survey, a company will collect plants from its space. You should also ask questions about how you plan to use your WiFi and your general needs. Using the information you have provided, the wireless site research company will suggest an access point model. This model will be used to create a heat map of your location. The heat map will include the recommended site of the equipment and a visual representation of how the wireless signal will be extended in your environment.

A predictive site survey is usually done for free. It's more of a sales tool than anything else. Many network equipment dealers offer free predictive site search only to help you reach an agreement. This can help transform a simple transaction into a more personalized customer experience. As a predictive site survey is usually free, some sacrifices are made in terms of quality and accuracy. In most cases, when more than three wireless access points are used, a predictive site search is not sufficient. Elements such as the location of the access point, wireless signal coverage and network performance are generally estimated and may require slight or even drastic changes to better align with your environment and needs.

Importance of Site Survey for Wireless Networks -

Wikipedia describes a survey on the site as "an inspection of an area where work is offered, to gather information for a project or an estimate to perform the initial tasks necessary for an outdoor activity. You can determine an accurate location, access, better site orientation and obstacle location. The type of on-site research and best practices required depend on the nature of the project. "

Raise or not search, that's the question.

Survey of urban works.
Wireless networks and urban construction have in common the need to control costs and controlled work areas. In general, there are environmental and zoning laws for urban construction that must be observed. With that in mind, we can see an example of a project that continued without adequate research plans.

Establishment of a wireless network in urban areas.

This project involved a complex building that would connect to a parking lot approximately 300 feet away. The company's main data center was in the parking lot across the street and there was no cable or fiber on the floor; therefore, the wireless connection must be used. The link seemed to be a very simple point, since there was a visible line on the Site Audit with the naked eye.

Why do a site survey and spectrum analysis?

When the link did not appear, we were asked to assess the situation. We immediately request research and in situ analysis of the binding spectrum. The engineer looked at me confused and told me that none of this had been done. We informed you that before continuing, an on-site investigation and spectrum analysis was necessary to determine why the link did not appear, and then we were able to determine what had to be done to make the link work.

Wlan Site Survey Tools There appeared to be a lot of interference in the areas where the original links were established. The alignment of the antenna was, therefore, the determining factor in the success of the relationship. According to the rating scale, channel one or higher offered the best chances of success. However, durability overtime was another problem. To guarantee the durability of the link signal, the noise level had to be improved. It has been determined that this could be achieved through the use of high gain antennas. The original radios purchased for the link had internal antennas and therefore, the gain could not be easily changed.

Finally, we ended up protecting different radios that can use external antennas. We have also moved the main assembly point to an area of ​​the building with less radio interference in the 2.4 GHz band. I believe that it is always better to investigate installing any radio. This task will always guarantee success the first time and save time and money in the long run. Finally, the survey can be used as a baseline to start the troubleshooting process if a connection suddenly fails.
Necessary steps to search the site
The following can be used as a checklist for successful point site searches:

Line of sight

Make sure you have a clear line of sight between the two wireless antennas
Spectrum analysis

After establishing a clear line of sight, you must perform a spectrum analysis to determine if there is noise between the two locations and the (legal) antenna installation area.

Noise levels

Check the noise levels in the frequency range in which your antennas will operate. If the noise levels are too high, it may be necessary to change the type or location of one or both antennas
If you find that the noise level in both areas is too high, breaking the antenna height can help
Remember: unless you find a place where the noise level is below the maximum limit, it makes no sense to continue

Identify maximum noise levels.

A snapshot of the noise level in your spectrum analysis does not always show the entire image. Some teams generate more noise with higher levels of activity.

Antenna alignment

The two antennas must be perfectly aligned to obtain a good signal strength.

Signal strength
If you are not receiving enough signal strength, you may want to switch to a higher gain antenna.

Conclusion: on-site study is essential for the success of a project
The general assessment is that time and materials were lost, which would not be the case if proper preparation had been carried out before installing the link. Below is the actual installation of the building mount point with an external Cisco antenna. This link has been running for six months, with no reports of bandwidth or link loss.

How To Do A Wireless Site Survey

How To Do A Wireless Site Survey With wireless systems, it is challenging to predict the propagation of radio waves and detect the presence of spurious signals without using test equipment. Even if the system uses omnidirectional antennas, radio waves do not travel the same distance in all directions. In contrast, walls, doors, elevator shafts, people and other obstacles provide varying degrees of attenuation, making the pattern of RF (radiofrequency) radiation irregular and unpredictable. Therefore, it is necessary to conduct a WiFi Site Survey Tool website survey (also called an RF website survey) to fully understand the behavior of radio waves in the operating environment before installing data points. Access.

Website Search Concepts

The ultimate goal of a Wireless Survey is to determine the number and location of access points (or mesh nodes) that provide adequate signal coverage throughout the installation or area. The city. In most implementations, "adequate coverage" means admitting a minimum speed or data transfer speed. To perform a successful search, you must associate the required performance with a value measured by research tools, such as SNR. A Wireless Survey Software also detects the presence of RF intesurveyrference from other sources that can affect wireless LAN performance.

The need and complexity of a wireless site survey vary depending on the installation. For example, a small three-bedroom office may not require on-site research. This scenario can probably be resolved with a single Wi-Fi access point (or router) located anywhere in the office while maintaining adequate coverage. If the access point encounters RF interference from another nearby wireless LAN, you can choose a different channel and eliminate the problem.

A larger facility, such as an office complex, an airport, a hospital or warehouse, or an outdoor space such as a city, usually requires a full search of the wireless website. Without research, users may have inadequate coverage and underperform in some regions.

When Performing a Search on a Wireless Site, Consider the Following:

1. Understand wireless connectivity requirements. To identify the ideal locations for access points or structure nodes, you must understand the specific network requirements that affect signal coverage. For example, the maximum interval between a client device and the access point decreases as the data transfer rate and the resulting performance increase. Therefore, you must know the target data rates (and performance) to interpret the search results correctly. Besides, client devices may have relatively low transmission power, which should be taken into account when using most of the website's analysis tools. Identify the technologies that the network will implement, such as 802.11g or 802.11n, and investigate taking these technologies into account.

2. Obtain an installation diagram. Before going too far with research on the site, look for a set of construction plans or city plans. If not, prepare a drawing that shows the location of the walls, corridors, etc. Site search tools import diagrams in different image formats. Mapping software is a good source for research in outdoor cities. If all else fails in the construction investigation, consider taking a digital photo of the fire evacuation diagram, which is usually present on the corridor walls.

3. Visually inspect the installation. Install before running the tests to verify the accuracy of the 
installation diagram. Now is an excellent time to observe the possible attenuation barriers that can affect the spread of RF signals. For example, a visual inspection will reveal obstacles to signs, such as brackets and metal partitions, elements that planes do not usually show. Also consider possible locations for mounting access points, such as ceiling plates or pillars. For external urban environments, it is necessary to carefully assess the situation and availability of lighting poles and water towers to assemble mesh nodes and connection equipment. These actions will make subsequent tests more fluid.

4. Assess the existing network infrastructure. Determine the capacity of any existing cable network that can interconnect access points or fabric nodes. Most buildings have Ethernet networks and, in some cases, fiber optic networks. Check how many of your existing systems may be available to support your wireless network. This will help designers later in the implementation when defining the architecture and vocabulary of the wireless network.

5. Identify the coverage areas. In the installation diagram or on the city map, indicate all the areas where coverage is required, such as offices, corridors, stairs, pantries, bathrooms, toilets, patios, parking lots, and elevators. Besides, it is essential to identify locations where users will not have wireless coverage to avoid wasting time inspecting unnecessary areas. Remember that you can survive with fewer access points and reduced equipment costs if you can limit your roaming areas.

6. Determine the central locations of the access points. When considering the location of wireless users and the range estimates for the wireless LAN products you use, calculate the positions of the access points that will provide adequate coverage in all areas of the user. Allow for some propagation overlap (typically 25%) between adjacent access points, but remember that the channel assignments for the access points must be sufficiently separated to avoid interference between the access points.
Take into account the mounting locations, which can be vertical posts or metal supports on the tiles. Identify the appropriate areas to install the access point, antenna, and data / PoE cable. Also, consider the different antennas when deciding where to place the access points. An access point mounted near an exterior wall, for example, can be the right place if you are using a remote antenna with a relatively high gain oriented in the installation.

7. Check the location of the access point. This is when the site search test begins. Most wireless LAN providers offer Wifi Survey Software that identifies the associated access point, data speed, signal strength, and signal quality. You can load this software onto a laptop and test the coverage for each preliminary access point location. Alternatively, you can use a third party website On-Site Survey tool available from several different companies, such as AirMagnet, Berkeley Varitronics Systems, and Ekahau.

Install an access point at each preliminary location and monitor the Walking Site Finder readings at different distances from the access point. There is no need to connect or access the distribution system, as the search tests only ping the access point or read with the strength of the beacon signal. Very important: I indeed consider the limit of the SNR range and the power of the uplink signal and interpret the results. To make it easier to move the access point to the installation, you can mount it on a pole connected to a car with battery and DC / AC converter. Otherwise, you should wear an extension cord and always look for where to connect the power (not recommended).
