Here Comes Multi-Gigabit Wi-Fi
Blog Category: Data Centers

Posted by: Paul Kish on May 01, 2014

It’s been about 7 years since 802.11n Wi-Fi devices operating in both the 2.4 GHz and 5 GHz frequency ranges hit the market, despite the fact that the standard wasn’t ratified until nearly 2 years later.

But now a new generation in wireless technology has arrived!

Operating strictly in the 5 GHz frequency range (5.17 - 5.33 GHz band), IEEE published the 5th Generation 802.11ac™-2013 Wireless LAN Specification early this year with current generation devices providing up to a 3-fold increase in throughput and the potential to eventually provide up to 10-fold at 6.77 Gb/s.

The Wire of Wave 2 Wireless
Blog Category: Data Centers

Posted by: Stéphane Bourgeois on February 26, 2015

There are some exciting new developments in the world of BASE-T Ethernet and wireless.

Last November, the IEEE 802.3 working group held a Call for Interest (CFI) on the need to develop the next generation BASE-T for wireless access points (WAPs). The main issues raised in the CFI were that next generation 802.11ac Wave 2 devices will require multi-gigabit Ethernet data rates, and that there is a gap between the 1 Gb/s and the 10 Gb/s data rates needed to support Wave 2 devices.

The IEEE 802.11ac wireless standard was approved in December 2013. Current Wave 1 devices are using 80 MHz channels and Single-User Multiple-Input and Multiple-Output (MIMO) antennas with a maximum radio speed of 1.3 Gb/s. To support these devices, the network connection speed needs to be at least 75% of the radio speed. Therefore gigabit Ethernet connections over Category 6 or high-end Category 5e cabling are adequate to support Wave 1 devices.

Power to the Cable
Blog Category: Data Centers

Posted by: Stéphane Bourgeois on March 19, 2015

Since it first came on the scene in July 2003 with the ratification of the IEEE 802.1af standard, Power over Ethernet (PoE) has become a “must have” for LAN deployments.

The first iteration, Type 1, had the ability to deliver up to 15.4 W of power over two pairs of a telecommunications cable from the source to support VoIP phones and other devices. The second iteration, IEEE 802.3at-2009 Standard, also known as PoE Plus, had the ability to deliver up to 30 W of power over two pairs from the source to the powered device. Even so, it wasn’t the most efficient and many IP-based devices now simply require more power.

Installing Category 6A: The Future is Now
Blog Category: Data Centers

Posted by: Stéphane Bourgeois on April 09, 2015

Category 6A twisted-pair copper received much attention when it first hit the marketplace in 2005. But adoption has been slow, since the 10 gigabit per second (Gb/s) capacity of Category 6A exceeds the requirements of most LAN applications. However, times are now changing. Data rates in the enterprise continue to climb. More devices than ever are being connected. Emerging applications demand higher performance and faster speeds. And those trends haven’t escaped the notice of industry standards bodies.

Choose Your RJ45 Connection Wisely
Blog Category: Data Centers

Posted by: Kristen Poulos on June 25, 2015

Field crimping a plastic RJ45 plug on the end of a horizontal cable to directly connect to an IP camera or WAP (wireless application point) may seem like a great idea. After all, plastic plugs are very inexpensive. A horizontal cable and one plug seems like a very simple option, and installation always looks neat and clean.

But, if this is the route you choose to go, then buyer beware: The methodology is riddled with pitfalls, headaches, and unexpected costs!

STP, UTP, FTP Cable & More: 7 Types & When to Use Them!
Blog Category: Data Centers

Posted by: Kristen Poulos on July 23, 2015

There are many acronyms used to describe shielded cables, from STP to F/FTP; while many are often used synonymously, nearly all of them have different meanings. This blog provides basic information about each style, as defined by ISO/IEC 11801:200, to clear up the confusion.

Copper Cable in a Wireless World
Blog Category: Data Centers

Posted by: Stéphane Bourgeois on August 06, 2015

We may be a wireless world, but we still need wire. We may need less wire than in the past, but devices requiring wireless networks also call for high-performance, quality wired infrastructure with cable that can handle increasing traffic and constantly changing technology and standards.

CCA Cable: 5 Reasons To Stay Away
Blog Category: Data Centers

Posted by: on August 13, 2015

When network infrastructure budgets are tight, it can be tempting to cut corners where you can. However, while copper clad aluminum cabling systems are offered as a cost-effective replacement for solid copper cable, they are anything but an effective solution. Learn 5 reasons why!
