The need for QoS, configuration on Extreme Aerohive

Introduction This blogpost will focus on the configuration of QoS policies on Extreme Cloud IQ (Portal). Aiming to provide a real scenario which led to the implementation of QoS for an organisation. Before diving into this I cannot stress on the point that QoS solution will be successful only if it is implemented end to end. The QoS marking and […]

Troubleshooting WLAN issues with 802.11 Frames – #CWAP9

I have pen down a some troubleshooting scenarios which I’ve come across while studying for CWAP exam. To begin with, Management Frames > Foundation of how wireless radios detect, join and operate on WLAN.Control Frames > Frames which control the delivery of Data frames. Data Frames > Carry actual data payload from/to layers 3-7. Some scenarios which frames can provide […]


CCK – Complementary Code KeyingDSSS – Direct Sequence Spread Spectrum OFDM – Orthogonal Frequency Divisional MultiplexingFHSS – Frequency Hopping Spread Spectrum There are various versions of WLAN standard developed to address different data rate and coverage requirements. IEEE 802.11b supports four data rates viz. 1 Mbps, 2 Mbps, 5.5 Mbps and 11 Mbps. – DSSS is used to provide support […]

CWNA , IEEE 802.11!

Hi IEEE 802.11 Key Concepts Let’s get started with the IEEE 802.11 Journey synopsis. Standards are defined at physical and mac-sub layer(data-link). We are referring to different ways of transmitting data over the air. Also how our communication signal would deliver information. One of the original ones we’ve come across is FHSS (Frequency Hopping Spread Spectrum) and DSSS (Distributed Sequence […]
