Readers’ Choice -Top Blog Posts of 2017

December 21, 2017 at 8:00 AM

 

As we wrap up another year, we’d like to take a moment to look back on some of our most popular posts. We pride ourselves on providing informative content for our readers by covering a range of wired and wireless technology topics. We sincerely hope that you enjoyed reading our posts as much as we enjoyed writing them and in case you missed anything, here’s a highlight reel of the most popular posts of 2017.

 

 1.       Cable Showdown: Cat6 vs. Cat6a

 

It’s a Cat eat Cat world out there and Cat6 and Cat6a are two of the most popular standards for Ethernet cables. So, how do you decide between the two? One may work better than the other, depending on your application. To help you pick a winner, we compared them side-by-side for a showdown of category proportions. To see how each Cat fared, read the post.

 

 

2.       White-Space Wi-Fi 802.11af

 

Waste not, want not, seems to be a growing way of life for many people these days, and that theme will soon apply to the Wi-Fi spectrum as well. The IEEE standard 802.11af, also known as white-space Wi-Fi or White-Fi, will utilize the unused space in the TV spectrum, the TV white-space, to support Wi-Fi networks. Read the post to find out how it all works.

 

 

3.       OM5 – The Next Generation of Multimode Fiber

 

OM5 was chosen to be the new standard for cabling containing wideband multimode fiber in the 3rd edition of the ISO/IEC 11801 standard. The acceptance of this standard is a milestone for the fiber cabling performance category because it extends the benefits of this revolutionary multimode fiber within connected buildings and data centers worldwide.

4.       802.11ax – The Next Big Thing

 

The IEEE will be adding to its 802.11 series of standards again with the launch of 802.11ax. 802.11ax is under development and will pick-up where 802.11ac left off by taking MIMO to the next level with MIMO-OFDM. This next big upgrade to Wi-Fi networks might not make its debut for a couple of years, but here’s a look at what’s coming.

 

 

5.       75 Ohm vs. 50 Ohm – Coaxial Comparison

 

Ohm may sound like something you’d say while meditating, but when it comes to coaxial cables, it is actually a unit of resistance. Ohms measure the impedance within the cable. Impedance is resistance to the flow of electrical current through a circuit. To see how 75 Ohm and 50 Ohm compare, read our post.

 

 

802.11ax - The Next Big Thing

March 2, 2017 at 8:00 AM

 

The IEEE is at it again. Its long-running 802.11 series of standards will be reincarnated yet again with the launch of 802.11ax.  This next big upgrade to Wi-Fi networks might not make its debut for a couple of years, but here’s a look at what is coming.

 

802.11ax is under development and will pick-up where 802.11ac left off by taking MIMO to the next level with MIMO-OFDM. MIMO-OFDM (orthogonal frequency division multiplexing) technology will be capable of subdividing signals even further which ultimately creates a bigger "pipe" to deliver larger volumes of data. This will significantly expand and increase throughput to deliver five times more capability than the gigabit speeds promised by 802.11ac. Lab-based trials of 802.11ax have even hit max speeds of 10.53Gbps, or around 1.4 gigabytes of data transfer per second.

 

As impressive as those speeds sound, 802.11ax is not just focused on being fast; its real focus is high-density Wi-Fi deployments. This means that the goal is not only to improve speed, but to enhance the ability of connections to remain active even when there is heavy interference. This will make the system more efficient with the sophistication to successfully route pieces of messages to their destination. 802.11ax will operate in the 5GHz band, where there is plenty of space for 80MHz and 160MHz channels.

 

Before you get too excited, implementing a new standard is a time-consuming and rigorous process, so we won’t likely see 802.11ax ratified until closer to 2019. Then it will take even more time before certified hardware hits the market.
