Part 2 of 2 In this blog we will look at some of the CLI commands you can now run to gain efficiencies when deploying or operating a Cisco Wireless Infrastructure using AireOS. I just deployed AP(s) in a small remodeled two story office area within a hospital. There are a lot of deployment tasks … More Cisco AireOS CLI and Importance of AP Name Convention (Part 2)
Part 1 of 2 Cisco AireOS CLI is one of the many tools a Cisco-centric wireless engineer will use to help configure and tune the deployment, operation, and optimization of wireless networks. The usefulness of the CLI is dependent on consistency and naming conventions. This blog entry is assuming you are designing or operating an … More Cisco AireOS CLI and Importance of AP Name Convention (Part 1)
I needed to test and suggest an enclosure for a behavioral psychiatric ward. The Oberon 1076-WA Enclosure withstood some abuse but the metal deformed. Here is the Video! The Oberon 1076-WA Enclosure withstood the abuse but the metal deformed. The other thing I noticed is that the 1076-WA shipped with the unit locked with … More Stress Test of the Oberon 1076-WA Enclosure
This is a non-scientific study of the resillency of the Oberon 1020-00 NEMA Enclosure. I have a behavioral psychiatric ward wireless design scheduled and I need to recommend an enclosure. I reached out to the nice folks of Oberon and they sent me an enclosure to test for the project. The test was three hard strikes from … More Stress Test of Oberon 1020-00 NEMA Enclosure
This topic will be broken out into several blog entries for your reading pleasure. 🙂 This is my interpretation and process for the PCI DSS 11.1 and 11.1.2. Your results might be different, or you may have a different interpretation. AP Rogue detection and mitigation is also part of the HITRUST certification requirements. 11.1 Implement processes to … More PCI DSS 11.1 and 11.1.2 – Rogue AP(s)
For want of a nail the shoe was lost. For want of a shoe the horse was lost. For want of a horse the rider was lost. For want of a rider the battle was lost. For want of a battle the kingdom was lost. And all for the want of a horseshoe nail. At … More Wireless PCAP Problem
Work Group Bridges (WGB) are used in Radiology, Cardiology Imaging, and Telemedicine for nomadic systems from Avaya, GE, and Phillips (for example). These systems do not have an integrated wireless NIC option. The department workflows require wireless service to reduce inconvenience to patients of moving their beds from a diagnostic room to an imaging room. … More Cisco Work Group Bridge Process
The idea was proposed on Twitter of wireless “Contention Zones”. A wireless “Contention Zone” is the purposeful channel design grouping access points (AP) configured for the same channel in close proximity. The 802.11 (WiFi) protocol uses several mechanisms to determine if the frequency is clear for a transmission opportunity (TxOp) or if the AP station … More Wireless Contention Zones: WiFi Hooey? OR Slicker Than Frog Snot?
The Behavioral Psychology Rooms are hardened construction to prevent patients from possibly harming themselves or others. The rooms have to go through a certification process which limits the placement and design for wireless access points (AP). The construction of the room is hardened in the following ways: Ceiling is drywall plus 20 gauge sheet metal. … More Hardened Behavioral Psychiatric Rooms
Channel Utilization is a statistic to represent the airtime utilization of a particular frequency or channel. The higher the Channel Utilization the more traffic is being transmitted and (hopefully received and demodulated!). There are several ways to see Channel Utilization in the AP, WLC, and Prime. WifiNigel has a very good article that shows many … More Channel Utilization Report In Cisco Prime 2.2
