Keeping up with Trending Technologies at the Del Mar Electronics Show

April 24, 2014 at 10:00 AM


In order to keep up with the latest trends in connectivity and technology we often place ourselves at trade shows, small and large. We want to not only provide stellar products but also grasp every opportunity to learn about the latest technologies in our engineering world.


So next week we’ll be exhibiting at the Del Mar Electronics and Design Show (DMEDS) on April 30th and May 1st. The show takes place at the Del Mar Fairgrounds in San Diego, California. L-com will be at Booth 747 displaying our latest wired and wireless connectivity products.


DMEDS is a low cost, high value design and manufacturing show for the electronics, medical and biotech industries. DMEDS focuses on IC products and services, electronic components, instrumentation equipment, fabrication products and services, engineering software and services, manufacturing products and services, contract manufacturing services and much more.


In addition to innovative new products, DMEDS also offers free industry programs and high tech presentations by leading edge companies.


Here are a few seminars that caught our eye:

·         American Manufacturing Trends: ‘Reshoring,’ Nearsourcing, and Technical Training 

·         3D Printing – Overview of Available Technologies & Commercial Applications

·         Social Media and the Supply Chain


This year it's expected that about 440 exhibitors and over 4,000 industry professionals will be in attendance. That’s a big opportunity for networking. Here’s a list of some companies that attended last year-- take a look to see if you should join in!



Why Use 802.3at PoE Technology?

April 17, 2014 at 10:00 AM


802.3at is the latest of the IEEE's Power over Ethernet (PoE) standards. Although it was released in 2009, it is still very relevant today.


Why? It offers up to 25-50 Watts of DC power to attached devices via a single Ethernet cable.


With the advent of 802.3at, a completely new class of devices could be powered directly via an Ethernet network interface. This PoE standard can be used with pan, tilt, and zoom (PTZ) IP cameras that require more power than stationary IP cameras, as well as other devices including dual radio WiFi access points, video phones, and laptops.


PoE enabled networking devices such as PoE IP Cameras, PoE Wireless Access Points and PoE IP Phones have become main stream in many networks because of the convenience of easy installation and great cost savings by not having to run AC power outlets.

Commonly referred to as PoE+ or PoE plus, 802.3at also has embedded intelligence via a newly defined data link layer (layer 2) protocol. The Link Layer Discovery Protocol (LLDP) allows the power source equipment to discover devices on the network and communicate with them to enable dynamic allocation of power levels.


PoE’s greatest benefit is that by utilizing its technology, both data and power can be sent to an Ethernet device via standard Cat5e/6 cabling. This means you do not need to install a power outlet at the device location and you can use readily available, relatively low cost Ethernet cabling.

If you’re looking to incorporate 802.3at technology into your application, here are a few products we suggest (all 802.3at compliant):




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!



Flirting with disaster



Cabling done wrong



Looks comfortable






















Our favorite “worst wiring job ever”



Do not touch any of these wires

Imagine seeing this at your next trade show



Network cable management done wrong




Now where was that Ethernet cable really supposed to go again?




Think your home entertainment system gets messy with wires?

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. ... (read more)


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)


Second number (Protection 
against liquids)



No protection


No protection


Protected against solid objects over 50mm 
(e.g. accidental touch
by hands)


Protected against vertically falling drops of water


Protected against solid objects over 12mm 
(e.g. fingers)


Protected against direct sprays up to 15o from the vertical


Protected against solid objects over 2.5mm 
(e.g. tools and wires)


Protected against direct sprays up to 60o from the vertical


Protected against solid objects over 1mm 
(e.g. tools, wires
and small wires)


Protected against sprays from all directions - limited ingress permitted


Protected against dust - limited ingress 
(no harmful deposit)


Protected against low pressure jets if water from all directions - limited ingress permitted


Totally protected
