10 of the Worst Cabling Nightmares

April 10, 2014 at 10:00 AM

 

At L-com, we pride ourselves on the professionalism and commitment to customer service. Our goal is to deliver the best connectivity solutions possible for the organizations we serve and support.

 

To that extent, we’re always dismayed when we hear of an organization compromising quality. But as discovered in recent Facebook updates, some organizations take the compromise way too far when it comes to their cabling infrastructure.

 

We decided to take a deeper look across the web for more examples and we were surprised and often shocked at what we found. Here’s our list of the worst cabling disasters we could find online. We hope you enjoy and hope this isn’t a facility you’ve experienced in your own work environment!

Don’t Plan a WLAN Until You Read Our WiFi Antenna White Paper

April 3, 2014 at 10:00 AM

 

Why? Let me ask you this.

 

Do you know how to choose the correct antenna for a better wireless connection?

 

With all of the various antenna options out there, it can get confusing as to which antenna to use and how they work. After reading this white paper, you’ll have the information you need to get started on planning your network. 

 

Our white paper - Choosing the right WiFi antenna for your applicationcovers common wireless network application examples and details the basic types of WiFi antennas that are available today. From choosing an antenna for a campus, to planning for an office environment, we give you a rundown of what antenna is best for your application and how-to tips for proper network design.

 


Here are just a few highlights from this free white paper:

 


There are two main types of WiFi antennas, Omni directional and directional

 

Omni directional antennas provide a 360° donut shaped radiation pattern to provide the widest possible signal coverage in indoor and outdoor wireless applications. An analogy for the radiation pattern would be how an un-shaded incandescent light bulb illuminates a room. Types of omni directional antennas include "rubber duck" antennas often found on access points and routers, omni antennas found outdoors, and antenna arrays used on cellular towers. ...

Outdoor Omni Antenna

Rubber Duck Antenna

Omni Antenna Array

I want to add WiFi to my office building (inside)

 

To provide wireless coverage to an inside office space, use omni directional antennas that provide 360° wireless coverage. The style of antenna typically used is the ceiling mount omni directional antenna. The antenna gain pattern for the ... (read more)

 

 


I want to install WiFi in a campus environment (outside)

 

In this case you can use several directional antennas with an omni directional antenna at the central building to connect the buildings in the campus. This is called a point to multipoint network. As with any outdoor WiFi network, clear ... (read more)

IP Ratings Guide

March 27, 2014 at 10:00 AM

 

One commonly asked question we receive from our customers is “What is the difference between IP67 and IP68?

 

Let’s first take a look at how these ratings work. Ingress Protection (IP) numbers are used to define a products resistance to moisture and fine particulates.

 

The first number after IP (shown in the left hand column below) denotes a products protection against solid objects like dust and sand.  This number can range from 0, meaning no protection against dust and sand, to 6, meaning 100% protection against dust and sand.  

 

The second number after IP denotes the part's protection against liquids.  It ranges from 0 to 8, from protection against direct liquid sprays to protection against long periods of immersion under pressure.  


Our IP67 Fiber Optic Cables, shown above, ensure protection from moisture and dust with an operating Temp: -40 to +85 Celsius.  Our IP68 Ruggedized Ethernet cables, shown on the right, offer complete moisture, dust, oil and UV protection for applications used in military, outdoor or industrial settings. 

 

Take a look below for further details on each of the IP categories. 

 

 

First number (Protection against solid objects)

Definition

Second number (Protection 
against liquids)

Definition

0

Don’t Miss Your Chance to See the Hottest Wireless Products

March 20, 2014 at 10:00 AM

 

 

Question: Where can you find over 7,500 technology engineers and buyers, over 350 top manufacturers, and a five-day conference with the most influential industry leaders (all of whom are eager to share their innovations and expertise)?

 

Answer: The International Wireless Communications Expo (IWCE) on March 26th and 27th. 

 

We believe that IWCE is not only a place to learn from and network with a wide range of industry professionals, but it also provides a chance to see the most innovative wireless technology. It’s an opportunity to discover new technology that could help you do your job more efficiently and effectively.

 

Also, did we mention that it's in Vegas?

 

How could you pass that up. We certainly won't.

 

Plus, the 2014 IWCE Conference will have a packed week filled with special events including panel discussions, workshops, and even courses on the "Foreign-Language track" for all you Spanish speakers out there.

 

We’re looking forward to exhibiting at IWCE since it’s the premiere wireless conference for engineers and installers. IWCE prides itself on being the authoritative annual event for communications technology in the working world. This year our team will showcase many new wireless products including our MIMO and multi-band antennas, which can be used in today’s 802.11ac applications. A few surprise products are also planned to be unveiled....so keep a lookout!

 

Some of the many products L-com will feature at IWCE include:

 
-Dual Polarized MIMO Antennas
-Coaxial and Data line Lightning Protectors
-NEMA Enclosures
-Coaxial RF Cable Assemblies and Connectors
-2.4 GHz and 5.8 GHz Radios and Antennas


Be sure to stop by our Booth #4141 at the Las Vegas Convention Center to meet our wireless experts and see L-com's latest wireless connectivity products.

802.11ac: What’s all the buzz about?

March 13, 2014 at 10:00 AM

 

Amidst the bustling and overpopulated race to find better, faster WiFi, there now exists a new wireless standard that will help you get there. You may even come in first place.

 

The latest IEEE standard for wireless networking, 802.11ac, is bringing high speed gigabit wireless connectivity to business, home, and government communications systems everywhere. 802.11ac offers up to 1 Gbps wireless transmissions and the ability to support up to eight MIMO spatial streams as well as 80 MHz channel bandwidth. This new advancement in wireless technology promises flawless voice, video, and data transmission to multiple end users at the same time.

 

If slow WiFi has you feeling down, 802.11ac is worth looking into.

 

802.11ac delivers faster throughput and better range than the previous 802.11n standard. 802.11n can deliver up to 600 Mbps with four spatial streams using one 40 MHz-wide channel. 802.11ac is engineered to deliver up to 1Gbps which translates to higher data rates and happier end users.

 

The new amendment’s ultimate intention is to achieve higher multi-user throughput in wireless local area networks (WLANs) and improve WLAN user experience especially for bandwidth intensive applications such as streaming voice and video.

Here at L-com, we continue to support the latest standardized technologies by offering high quality, high performance products, including those for 802.11ac applications.

 

Our series of 802.11ac indoor and outdoor WiFi antennas feature 2.4-5.8 GHz operation for a variety of applications. L-com currently offers 802.11ac ceiling antennas, panel antennas, rubber duck antennas, and Omni antennas.
