Hurricane Maria - Lessons Learned - a panel discussion at the CIO & IT Leadership Conference #PRisIT


September 20th, 2017 will be a date that will be remembered for a long time by many. To some, it was a day of tragedy, for me it was a date for maturity.  Maturity, because Hurricane Maria was the "test of fire" for our company.  The worst that could happen, happened and it depended on everyone as a team to overcome it. And we did! 
 
If anything Hurricane Maria taught us was that our "infatuation" with fiber optics connectivity needed some revision.  Many don't know the fact that wireless technology saved the day after the hurricane.  Even if many did not noticed!  Several companies like ours provided wireless Internet and data services to many critical operations including the Disaster Management Center at Centro de Convenciones, critical connectivity for Evertec / ATH, Hacienda, FEMA, US Army Corp. of Engineers, among many even including connecting cellular towers for mobile service. 

As of May 10th 2018 Sin Comillas, a local business news outlet, reported that the local cable provider customer base was 80% up.  Not to kick a dead horse, but this puts forward the fragility of wireline networks.  Our customer base was 80% up just 8 weeks after the hurricane.  I use this example to highlight the true advantage of a wireless based infrastructure.  Although is not Hurricane proof, it can be reestablished far quicker than wireline.
At the 2018 Puerto Rico IT Cluster: CIO & ITLeadership Conference, I was able to participate in a panel where the effects of hurricane Maria on the telecom infrastructure on Puerto Rico were discussed. Lessons learned and next steps to be taken were among the topics of interest.

 (1) Tell us about the biggest challenge you faced after Hurricane Maria


There were many challenges faced after Hurricane Maria, starting from the most important part of any business, Our Team.  A small group of our dedicated staff, stayed at our facilities during the hurricane, they were responsible for monitoring and logging all incidents related to the hurricane.  I thank them for their efforts, as they were the "first responders" of our plan. Like many others, just getting our staff with the basic necessities so that they could be able to work was a challenge. Food, Gas and even a place to stay were provided to our employees. Some of our staff members turned our facilities into their temporary homes, as many brought the rest of their family to stay during the day. Another challenge was logistics, including physical access to our towers, our customers and other locations for repair.  Also, related to logistics, getting supplies from the mainland turned to be a huge problem.  The federal government was controlling all inbound cargo to PR. 

(2) Can you share with us a brief summary of how you overcame this challenge?

We relied on our customers as partners to overcame many of the challenges.  Starting from reaching cooperative agreements with gas stations so that we could have gas to operate and for our employees. Also, we partnered with a restaurant that provided our staff and family with daily breakfast and lunch. 

The logistics challenge was one that was a bit difficult to overcome.  Thankfully Most of the principal roads were somewhat cleared for traffic by the local citizens, letting a hand to the local government to quickly recover access to transportation which is critical on this kind of event. 

Getting the supplies from the Mainland to PR in order for our company to quickly repair the damages presented the biggest hurdle as the US government was controlling all sea and air traffic. The most cost effective way of shipping 20+ pallets of equipment would be by sea, but we had to rely on more costly air transport to get our supplies in a timely manner. This with some issues in terms of being able to get an air transport window by the FEMA controlled airport.



(3) Where is your company now vs. pre Maria and how are you preparing to become more resilient

We are bigger and stronger! We have learned many lessons along the way and rectified many weaknesses.  Among our plans that are being executed right now are:

-Non-dependence on any government help, during a disaster, your company must count with all the resources necessary to operate completely disengaged from any help or assistance from the government.  This includes shelter, food, water, gas, transportation and communications. 

-Alternative long run power.  We have revised our backup power plan and expanded it capabilities from isolated operation to 4 continuous weeks.  The addition of solar energy is critical, but must be integrated property to have a high survivability rate. 

-Redundancy, Redundancy, Redundancy.  Any operation that relies on Internet access for its continuity, must include several, fully independent connectivity providers.  We all now by now that a fiber cut or a copper line can take months to get repaired so to guarantee the survivability of your business, other technologies like wireless or satellite must be included in the contingency plan.  We relied on fiber for backhaul but we are building a multi-gig microwave backbone that goes around the island and thought it. This network will protect our services for future events.

5G WARS: The Race for Gigabit Internet

The race is on!

The race started some years ago, when Google upped the ante back in 2012 and launched Google Fiber.  This ignited the gigabit fever in the US market.


Now, 6 years later, many providers (including Google Fiber) have recognized that providing gigabit service via wireline technologies (Fiber, Copper and Coax) is not a easy feat.  Most have scaled back or halted their deployments

5G to the rescue

As previously discussed5G technology is capable of delivering fixed and mobile Internet at speeds of 1000 Mbps and more.  Hence why Gigabit Wireless have been acknowledged as the most cost effective way to deliver gigabit Internet to end users.

But what really is Gigabit Wireless? Many define Gigabit Wireless  as any technology capable of delivering up to 1000 mbps Internet access to a consumer via any wireless technology. Also, this definition does not differentiate between fixed access (home and businesses) and mobile access (phones, hotspots).

Having said that, how can a service provider deliver Gigabit speeds over a wireless medium? Currently, mobile operators are testing fixed wireless technologies in various band to achieve this feat.  A lot of focus is being put on millimeter wave technologies in the 28  and 38 GHz bands.  New companies like Starry and Phazr have prototype trials with several operators like ATT and Verizon. Other operators are focusing their efforts in microwave  upper bands like 60 GHz using systems from industry veterans like Siklu and newcomers like Facebook

Facebook's Terragraph node in San Jose CA

Most of these trials and deployments are being labeled as 5G, but is 5G equal to Gigabit Wireless and vice versa? As of today, we can agree that they are equal, as both pursue the same goal of delivering Internet at 1000 mbps speeds in both fixed and mobile scenarios.

Wireline rebounds

Although the wireline industry has been stagnant for some years, new technologies capable of achieving gigabit speeds and more have been recently deployed and validated.  This comeback, backed with DOCSIS 3.x and G.FAST technologies, shines  a light of 
retaliation to the wireless industry and shows that the wireline technologies are fighting to keep  their place in the race for Internet access.  

As more operators implement these technologies, more turf will be held by the wireline technologies against the posible 5G onslaught.

Can Wireline technologies stop the incoming 5G wave? That remains to been seen, but I would venture to say that the true winner of this war would be:

HYBRID NETWORKS

I believe that the true winner of this technology confrontation would be the concept of Hybrid Networks, the mix of both wireless and wireline.  When coupled together, fiber and wireless technologies can become the true solution to scalable, fast deployable networks that can serve 1 Gbps and above speeds to the end user. A fiber networks gives you the scalability and bandwidth capacities for future growth, and the wireless networks give you the speed and the flexibility to reach the end users.

Those operators who leverage the strengths of both technologies to complement each other and provide access to the end user in the most fast and cost-effective way, would be the true winners of the 5G WARS.
