CTS 067: Giving Back To The Wi-Fi Community with Rasika Nayanajith

In this episode, we welcome Rasika Nayanajith (CWNE #153, 2x CCIE) from Australia. We discuss the different ways to give back to the Wi-Fi Community. We hope that this episode will inspire a lot of Wi-Fi engineers.

Interview with Rasika Nayanajith

Our Guest

Rasika is the Team Leader Network at La Trobe University in Melbourne Australia. He created the well known Wi-Fi related blog and he has been designated VIP by Cisco to be very active on the Cisco Support forum. He has done a lot to give back to the Wi-Fi community and we were very honored to have him on the show.
You can follow him on Twitter @mrncciew.


We discussed the different ways to give back to the community:

  • Blogging
  • Participating in vendor’s support forums (Cisco Support Community, Aruba Airheads Community, Aerohive HiveNation Community…)
  • Becoming an Instructor
  • Presenting at conferences
  • Mentoring

We also deep dived into Rasika’s experience in creating and maintaining his blog. Rasika gives some valuable pieces of advice for anyone wanting to blog or participate in vendor’s support forums.

Arris to Acquire Ruckus

Arris and Broadcom jointly announced that they have entered into an agreement for Arris to acquire Brocade’s Ruckus Wireless and ICX Switch business for $800 millions in cash.

Arris, which is currently mainly offering equipment intended to the home market, hope to expand its presence into other markets such as education, public venue, enterprise and hospitality.


FCC Lets Wireless Carriers Use Wi-Fi Airwaves Critics Worry about Interferences

FCC has officially gave the green light to carriers for them to be allowed to use LTE-U over the 5GHz band. Carriers will then be able to offload some of their traffic to the unlicensed 5GHz band used by other technologies such as Wi-Fi.

Technically speaking, this is not really a good news for our Wi-Fi networks, since LTE-U is a less polite protocol, and Stations will start broadcasting a the less occupied frequency without waiting for a channel to be open. Most Wi-Fi experts are skeptical and a lot of debates and talks have been happening on Twitter since the announcement.

This is week is the Mobile World Congress in Barcelona, and we will see if people will be talking about it.

CTS 061: Wi-Fi For The Non-Profit Community

Glenn Cate, guest hosts.

Glenn Cate, CWNE #181, is our special guest who has done many Wi-Fi projects for the non-profit community. He provides his experience and tips on giving back.

Wi-Fi has become an expected service throughout our communities.  From shopping malls to restaurants to businesses to airports to our homes, we just anticipate using Wi-Fi connections with our smart devices.  Yet, there are many organizations that give so much back to our communities that also need Wi-Fi:  free health clinics, community service centers, churches and religious organizations, schools and neighborhood centers.

The problem usually is not that Wi-Fi is not important, but that these non-profit organizations do not have the skilled resources or financial backing to install Wi-Fi services.  So many times, poorly designed Wi-Fi is installed or no Wi-Fi at all is present.  WLAN professionals can give back by providing their skill set in helping plan and deploy Wi-Fi for non-profit organizations that give so much to our communities.

Projects Glenn Cate has worked on:

  • Church (three buildings)
    • Six APs
    • Server closet
    • Five 24 port unmanaged switches
    • Ethernet pulling/punch down.
  • MS/HS/elementary school of 600+ students (four buildings plus small trailers)
    • Site survey
    • Vendor AP comparison
    • Pulled/punched down Ethernet cables
    • Deployed APs
    • Initial cloud configuration
    • Knowledge transfer.
  • Several churches
    • Consultation on Wi-Fi uplift and recommendations
  • Church(three buildings)
    • Site survey
    • Pulled/punched down Ethernet cables
    • Ethernet drops to offices
    • Security appliance configuration
    • AP installation
    • Fiber run to remote building
    • Post validation testing
    • Knowledge transfer.

In this episode, Glenn speaks about getting into the project management side of things including talking to directors, steering committees, and technical resources. A question Glenn answers is how do some of non-profits have the funds to pay for enterprise-grade equipment? You’ll be surprised.

One question I give to Glenn is what kind of obstacles does he run into while doing the installation? What if the work requires more than just your expertise and manpower?

Lastly, why does Glenn provide his expertise and services for free to non-profits? The reason why is important.

I hope you enjoy this interview with Glenn Cate. If you have any questions please submit a comment below. You can find Glenn Cate on Twitter and on his blog.

CTS 033: Community

CommunityHave you thought about joining the wireless community but aren’t sure how to get started? You want to help educate others but can’t decide on a platform to use.

Giving back to the wireless community is one of the reasons why we have a great group of people. We like to share and discuss topics with passion.

In this episode, I list out some ways you can participate in the wireless industry.

Create A Blog

You can start off by guest blogging on someone else’s blog. It’s a great way to get started and share your content with the community. The next best thing is to start your own blog for free using WordPress or Blogger.

This is a place to write about your experiences, provide tutorials on how to do something, or even a place to keep your notes for the certification you are studying for.


Probably the least required effort to get involved. Only requires 140 characters or less to get your thoughts out there.

Many wireless professionals are on Twitter participating in a lot of great wifi discussions. Twitter has become the go-to method of communicating with other professionals. Many conversations get heated and it can be interesting to watch and learn from those discussions if you feel that you are unable to provide any other value.

Additionally, the wireless community is very supportive in sharing others’ blog posts with their followers.


If there’s any place where you can meet those you communicate with on social media in person. Put a name and a voice to the person behind the avatar.

The most valuable part of a conference are the tabletop discussions that occur over a couple of drinks. That’s in addition to the presentations scheduled throughout a conference.


Video tutorials are a great way to contribute back to the community in a learning way. Many people, including myself, are visual learners. Reading how to do something sometimes isn’t the best way to learn but with the support of a video it can become a powerful duo.


This is the route I took, obviously. A podcast enables you to fully participate in the community in meaningful ways. Audio is an easy way for a listener to consume content. It can be listened to anywhere.

Doing a podcast also forces you to learn subjects to create content.

All you need is a microphone and a voice.
