Wireless LAN Operations Courses

smart home 3096224 640We are told that 60% or more of customer calls to their service providers are wireless networking (Wi-Fi/WLAN) related.

With more and more Internet of Things devices connecting to the Wi-Fi/WLAN service providers need to focus and polish their team skills on this subject. Furthermore, we continue to get newer and more capable versions of Wi-Fi (Wi-Fi 4, Wi-Fi 5, and now Wi-Fi 6 and Wi-Fi 6E).

Use of the correct tools, correct troubleshooting, and correct deployment of WLAN networks is crucial in todays business model. 

We have developed the courses in this area to help our Service Provider customers - addressing Customer Service Representatives (CSR's), Technicians (Field and CO), and Engineers alike.  The courses in this category have an immediate impact by reducing call backs, reducing truck rolls, improving communication, and improving customer service.  From the CSR, to the field technician, the following courses efficiently address this need for improved understanding and skills in WLAN Operations.

IPv4 Courses

v4cloudThe great Internet that we know and love suceeded because of the Internet Protocol version 4.  The Internet Protocol is the language and addressing of the Internet.

The courses in this category will provide hands on skills and knowledge training focused on IP version 4 operations.  This is the dot decimal format so many of us have used in our networks, our homes and our businesses.  Who has not said "192 - dot - 168 - dot - one - dot - one", or something very similar? IPv4 is about addressing, subnetting, private and public, Network Translation, QoS (Quality of Service), and so much more.

Knowing these subjects is critical to supporting Internet based services for any technical person, whether you are in support, or installation and maintenance.

IPv6 Courses

v6cloudWith the supply of IPv4 addresses exhausted, everyone in networking is scrambling to convert their networks and their knowledge/skills to the next generation Internet Protocol - IPv6. 

Tier 2 and Tier 3 Rural networks are rapidly tackling the challenge of conversion to IPv6.  Most Tier 1 service providers have already done so.  Unlike IPv4 which has a 32 bit number-dot-number-dot-number-dot-numer (dot decimal) format and lnguage, IP version 6 uses a 128 bit number-colon-number-colon-number-colon-number-colon-number-colon-number-colon-number-colon-number format, and instead of being dot decimal, this is all hexadecimal!  More numbers means more addresses, plus it means more functionality, and different functionality.

Our "Hands On" courses teach IPv6 from the basics to the advanced subjects. 

Whether you are a field technician, central office engineer, or IT person, you need a solid hands-on skill base on IPv6.  The courses below will get you there.

Wireshark Courses

WiresharkFinWireshark Packet and Protocol Analysis skills are critical in today's networks.  Protocols are like languages.  Learning to analyze the network protocols requires us to learn a number of different languages of the network.  Our courses teach you Wireshark, but they teach you through the study of these protocols.  Like any language, you have to "Capture Every Day" (click on the link to find our "#captureeveryday" posts) to keep yourself fluent, and keep your skills sharp.

Whether you are a field tech, a data center engineer, or a generalist in IT, you need to know how to use Wireshark and you need to learn these languages.  For many, this free tool has been under the radar, or even kept off the radar, for far to long.  The most common problem reported by users is "my network is running slow".  Swapping equipment, or re-booting gear, may temporarily mask the problem. 

The solution is to capture and analyze packets, and learn how to troubleshoot the issues, while learning how the Internet and all of the protocol languages actually works!  Here are the most popular Wireshark classes.

L2 Ethernet Courses

cloud l2ethernetInvented in the 1980's by Bob Metcalfe - Ethernet revolutionazed bandwidth and connectivity in Local Area Networks (LANs).  That was then.  This is now.

Today Ethernet is used to provide services around the world and is used not only in the LAN, but the WAN as well.  We can no longer simply call Ethernet a LAN protocol.  As the protocol has developed, so have the features and functions.  Learning Ethernet switching and learning the fundamentals of how Ethernets operate is crucial in todays networks for anyone in the networking field.  

We have combined L2 Ethernet and L3 courses listed under the IPv4 course category and the IPv6 course category

Wireless Courses - Wi-Fi and Cellular

WirelessTechThe world of wireless is a broad set of technologies and solutions.

The following courses are available via Web Based Delivery only: they are either instructor led (a live instructor using Web based training technology like Zoom, Webex, MyRoom, etc) or Self Paced using our Online School.  Understanding Wireless, is an almost overwhelming task. There are so many different categories of Wireless: Cellular, Wi-Fi, Bluetooth, Enabling the Internet of Things - technologies that support wireless IoT capabilities, and so many more. Having knowledge and skills in wireless technologies is critical in today's networks as everyone uses wireless in some form or fashion.  The courses in this category are targeted to developers, implementors, and testers using the appropriate level of technology depth to provide knowledge, understanding and skills in their job functions.

Enabling the Internet of Things Courses

web 2496193 300A variety of technologies are being created and standards released that support the Internet of Things (IoT). 

From wireless sensors to protocols that provide IoT specific functionality, developers and testers will be very interested in the courses of this category.  These classes are all instructor led, web-based delivery or online self paced video courses at the Online School.

MPLS Related Courses

mplscloud1Multiprotocol Label Switching (MPLS) appeared on the networking technology horizon and has revolutionized the core service provider and enterprise networks.  From Layer 3 VPN technology, to Traffic Engineering, to Layer 2 transport, MPLS ushered in new services all based on the Internet control plane technologies.  These hands on courses teach the fundamentals and then dive deep into the various MPLS based solution using hands on lab exercises to drive home how it works.

Technology Overviews/Briefings

pexels photo 936081The courses in this category are designed to be short (usually 4 hour instructor led, web based delivery) format, technology overviews designed to meet the knowledge level needs of managers and supervisors, or just individuals who would like a higher level briefing on how a particular protocol or technology works. 

Service Provider/General Courses

birds flight freedom sky 162196The courses in this category and either general telecommunications or targeted to the service providers.  These courses can be very helpful for new employees, like the Telecom 101 course, or they provide topical surveys of telecom related topics.  Some of the courses are available as self paced, online instruction, or as instructor led on site instruction.  See the course details for more information.
