The “Ending” of Layer Two Redundancy

Although layer two redundancy should never end, this is the final chapter of understanding layer two redundancy in the network. Last week I talked about how and why STP (IEEE 802.1D) is important in the network and the problems and causes of not having it which can turn your network against you and everybody on it. Today’s post will talk about how a switch decides which one is in charge on the network and which ones aren’t Continue reading

The Middle of Layer Two Redundancy

In the month of August I talked about the “beginnings” of layer two redundancy mainly looking at the basic foundations and fundamentals of having layer two redundancy. Let’s continue are discussion about redundancy in the layer two environment. Continue reading

Welcome Super WiFi

Wow July is almost over and I only posted one topic! Before August comes up I wanted to post at least one more topic which deals with the wireless side of the networking world. Ever heard of Super WiFi? The IEEE has published this standard recently its official number is 802.22. What does Super WiFi bring to the table compared to other WiFi Standards? Well according to IEEE these speeds can bring up to 22Mbps to devices as far has 62 miles! How is this range possible? Well ever since the United States made the switch to digital over the air broadcasts there was this “extra space” Continue reading

802.11b

Continuing where we left off the discussion, todays post will be talking about 802.11b wireless standard that was developed by IEEE. Yesterday’s post we talked about the 802.11a standard. (See the post 802.11a) We also we talked about the 802.11 – Legacy standard (See the post 802.11 – Legacy) and in the beginning of the week I went over some Basic Wireless Concepts (See the post Basic Wireless Concepts) So now that we are up to speed lets learn about the 802.11b standard.

802.11ac Standard

Some things are making news in the wireless world, the IEEE wants another wireless standard in the mix called the  802.11ac, now the fastest standard they have is the 802.11n(speeds up to 300 Mbps), which was recently published in October of 2009. What is so great about the 802.11ac development? Well one thing is the speed, it is estimated that it will be able to carry up to 1 gigabit per second! Continue reading
