IT Consulting Denver — Widespread use of wireless

Companies in the Denver metro area and beyond are using more and more wireless.  The predominant wireless technology today is 2.4Ghz which has been popular for years but now faces a major issue.  Organizations that have offices in a multi-tenant building notice the major issues with 2.4Ghz wireless networks.  The biggest issue with 2.4Ghz is the interference that is caused by these wireless access points.  With 2.4Ghz wireless networks there are only three none overlapping channels.  The non overlapping channels are 1, 6 and 11.  Even though there are 11 channels there are only three that can be used that are non overlapping with one another.  If two access points are placed next to each other and don’t have at least five channels of separation there will be interference and the network will be severally degraded or not work.

To overcome the issues with 2.4Ghz networks NOYNIM is recommending to move to a 5Ghz wireless network.  With a 5Ghz access point one will have 23 non overlapping channels.  While 5ghz doesn’t provide the range that 2.4ghz provides it provides a more stable network when multiple wireless networks are in use.

IT Consulting Denver NOYNIM is not advocating that 5Ghz is better than 2.4Ghz.  We are simply saying that depending on your need it may be better.  When there are many access points around it is recommended to use a 5Ghz access point as it has more non overlapping channels.  5Ghz also offers more throughput at a shorter distance.  This means that more access points may need to be placed in a building to get proper coverage.  Even though 5Ghz has been out for quite some time there are many devices (laptops, mobile devices, etc) that still don’t have wireless cards to support 5Ghz.  Whenever a 5Ghz network is implemented it is very important to make sure that a 5Ghz network interface card is available on the client device.
