5 Considerações Inteligentes (Intelligent Considerations) for High Density Networks

By Juliano Forti, Global Product Line Manager, HP Networking


Juliano FortiFutebol is in full-swing in Brazil as group play moves into week 3 for the World Cup. The tournament has been very exciting so far with surprises (Spain losing early), excitement (USA beating Ghana), and a less than favorable outcome for Brazil (Brazil tying Mexico).


In my previous post, I wrote about the deployment of HP wireless networks in 3 of the World Cup stadiums (Porto Alegre, Manaus, and Curitiba) with capacities between 38,553 and 42,991 spectators. As these games become bigger and bigger, the venues will see more and more attendees, which will bring about technology challenges, among them network throughput, application usage, traffic levels, and capacity of coverage. Each of these plays a key role in creating the best end-user experience possible.


Juliano Forti_2a.pngIn this post, I will go into greater detail about the smart considerations IT professionals and event venue managers should think about when deploying high density networks. Check it out:

  1. Cell Size: When deploying for high density, IT professionals should take cell size into consideration. Cell size is the diameter of the coverage provided for network access, and emphasizes deploying for capacity as opposed to deploying for coverage. Having a smaller cell size requires a greater number of access points and also allows for greater throughput, which is the quotient of the amount of data made available over the sum total of users on the network.
  2. Interference Detection and Mitigation: Whenever possible, deploy on a 5 GHz band versus a 2.4 GHz one. The 5 GHz band has 23 channels available and offers better speeds for users, while 2.4 GHz band only has 3 channels which are not only shared by legacy routers but also with other devices like keyboards, mice, microwaves, and speakers, which can cause interference. While Wi-Fi Clear Connect advanced radio resource management (RRM) and the Intelligent Management Center’s (IMC) Spectrum Guard can assist in detecting and automatically mitigating interference issues, moving 5GHz capable client to the less congested 5 GHz band is a good decision overall.
  3. Physical Location: The physical location of a high density network is very important. Wireless signals for example do not penetrate well through concrete, which is often the material used to design stadiums such as those where the World Cup is being played. Therefore IT professionals and venue managers must strategically consider the placement of wireless access points while also placing directional and omnidirectional antennas in order to ensure the effectiveness of their implementation.
  4. Traffic Load: Match attendees will be exiting, entering, and wandering around the stadium during the game, either to get food at the concession stands or look at the game from a different angle. As a result client load balancing should be considered as well to reduce network congestion over an area by distributing client sessions across other access points with overlapping coverage. Managing this traffic load will ensure that attendees will be able to share, tweet, and upload content continuously without any network drops.
  5. Application Load: Finally, because match attendees will be using numerous apps during the game, application load must be a consideration. Video applications for example consume an extremely high amount of bandwidth and will require higher throughput networks to handle the data.

With these considerations in mind, IT professionals and venue managers will be on their way in creating a welcoming and smooth event which gives all attendees the opportunity to share their experience.

Enjoy the games, and vá Brasil!
