Building a Better Mousetrap for Hotels

By Mike Collado
February 12th, 2013


We announced yesterday that we’re debuting  the INFINITY ACCESS™ Passive Optical LAN (POL) Fiber-to-the Room (FTTR) solution for hotels during the 9th Annual HTNG North American Conference at the Westin Buckhead in Atlanta, February 25-28. 

This solution enables dedicated, symmetrical and secure high-capacity Gigabit Ethernet (1GE, 1Gbps) links to each hotel guestroom for delivery of next-generation IP-based voice, data and video services such as 4KTV.

So what’s the big deal?

The Challenge

Hotels are being challenged to provide multiple forms of high end connectivity to their guests as travelers become more tech savvy and increasingly dependent on staying in touch with the office, email, family, etc. while away from home. In-room entertainment in the form of HDTV, Video on Demand, streaming music significantly add to the load.

The amount of bandwidth per guestroom has and will continue to increase dramatically for some time.

This follows the overall bandwidth consumption trend forecasted by iGR: by 2017, mobile bandwidth in the U.S. will grow six fold from 2012 levels

What Must Be Done

Hotels need to deliver voice, video, and data to guestrooms, conference rooms, gym/spa, and even restaurants in a cost-effective manner that provides ample bandwidth for today’s needs.

More importantly, there needs to be a pathway for future growth as internet bandwidth demands increase; guestroom television viewing advances to 4KTV from today’s HDTV; and voice moves to VoiP.

The most economical way to do this is by delivering individual Gigabit Ethernet circuits to each room from a centralized server in the hotel’s data center.

Copper-Based Ethernet

One option is to deploy copper-based 1GE over existing Ethernet infrastructure in the hotel. This would alleviate running new cabling in the building.

Sounds good, but the risk is that the existing copper plant may not be high enough quality to support 1GE speeds.

What’s worse is that this path would provide little-to-no future growth because the physical medium will not support higher data rates (i.e., 10Gbps).


FTTR is the other option. While it will require deploying fiber optic cable from the data center to each floor and then from the data closet on each floor to individual rooms, fiber has the upside of being relatively easy to install and, most importantly, will provide almost unlimited room for future bandwidth expansion.

There are two basic ways to move data to the rooms: traditional GPON (Gigabit-capable Passive Optical Networks) and WDM-PON (Wavelength Division Multiplexing-Passive Optical Networks).

With GPON, a single fiber is deployed from the data center to a splitter in the floor closet, where individual fibers run to each room.

The upside is that GPON is established technology, cost-effective and widely-deployed.

The downside is that bandwidth per floor is shared among the rooms; that bandwidth is also asymmetrical.

And, while upgrading bandwidth is possible, it must be done on all devices at once. Which reveals a key risk: sharing. IOW, if a remote unit malfunctions, it means taking down an entire section of rooms. 

WDM PON – which is the technology SOLiD’s INFINITY ACCESS is based on – also uses a single fiber to the floor closet splitter and individual fibers to each room.

The difference is each room is served with its own unique wavelength running symmetrically at 1Gbps up and down stream.

Upgrading bandwidth to 10G is possible on a room by room basis, without affecting other rooms on the floor.

And service is maintained among a sector of rooms even if one room is down for maintenance because the individual wavelengths run to each room.

What Do You Think?

We predict an interesting debate among the hospitality industry with arguments for all three approaches.

Our take, however, is that the “data tsunami” trend in mobile broadband is similarly finding its way into the hospitality space (and other industries). And, therefore, it will be incumbent to choose and deploy infrastructure that is both highly scalable, stable and flexible.

SOLiD Is Revving Up For DAS Congress

By Mike Collado
May 16th, 2012

SOLiD is once again sponsoring ACI’s 5th Annual DAS Congress at Caesar’s Palace May 21 – 23.

We’re looking forward to a busy two days of presentations, meetings and fun – it’s Las Vegas, afterall!

Here’s what you can expect from SOLiD:

The SOLiD Learning Center

Put on your thinking cap and visit the SOLiD Learning Center.

Located in the Salerno Room across from the exhibit area, we’re welcoming attendees from 9 – 5 on Tuesday and Wedesday.

This is the perfect opportunity to get a close up of SOLiD’s DAS and digital backhaul solution portfolio and have the chance to discuss your projects with the SOLiD team.

Hang out, grab a refreshment and register for our giveaway raffle!

DAS Trends – What’s Hot & What’s Next?

We’re kicking off the conference Tuesday, May 22 at 9am with our friend Iain Gillot, a leading industry analyst and president of iGR, who joins Seth Buechley and Saeed Anwar (SOLiD’s president and CTO, respectively) to explore the most talked-about topics at the recent DAS in Action and CTIA conferences – Small Cells and Backhaul.

Iain has opinions. And so do we.

Plus, we’ll examine how DAS is likely to evolve in-time for next year’s DAS Congress.

(Hint: think convergence.)

Establishing Universal Indoor Public Safety Radio Coverage

When there’s an emergency, communication is paramount.

But, too often, the Public Safety radios used by first responders don’t work inside of buildings.

And let’s not forget, the people that live, work or visit the building also need their mobile phones to work in the event of an emergency.

Industry expert Gregory Glenn, Director of Product and RF Engineering with TriPower joins SOLiD’s president, Seth Buechley, in a discussion among industry experts to explore how to make buildings safer by including Public Safety on the DAS.

The panel will explore why this problem exists and address the typical objections for putting Public Safety on the DAS – including technology, financial, liability and management concerns.

Finally, the session will suggest a call to action: the formation of a Safer Buildings Coalition to ensure universal indoor Public Safety radio coverage.

See You in Las Vegas!

Do you have any burning questions that you’ve been afraid to ask?

We’re Exhibiting & Presenting at NTCA – Come See Us!

By Mike Collado
February 9th, 2012

Please join us at Booth #104 during the NTCA Annual Meeting & EXPO on February 14 & 15 at the Manchester Grand Hyatt Hotel in San Diego. We’ll be showcasing our ClearLight ACCESS™ fiber multiplexing solution, which increases existing fiber plant capacity 16x.

This is no ordinary multiplexor… ClearLight ACCESS features patented tunable laser technology which delivers long-haul high-capacity digital distribution efficiency at middle-mile economics for rural telecom providers.

Service providers struggling with fiber exhaustion are invited to attend our case study presentation on Tuesday, February 14 at 3pm in Room Ford B on Level 3 to hear how Empirical Networks solved its capacity shortage problems.



Cliff Crowder, CEO of Empirical Networks faced a serious challenge. Demand for bandwidth and capacity from the telecom provider had created a shortage of network capacity and fiber exhaustion – which meant missed revenue opportunities.

Instead of pulling new fiber, Empirical deployed ClearLight ACCESS™ from SOLiD Technologies.

Please join Mr. Crowder at the NTCA Annual Meeting to learn how he increased capacity 16x with Empirical’s existing fiber plant and lowered CAPEX and OPEX costs with ClearLight ACCESS.

Mr. Crowder will share why he chose ClearLight ACCESS, how his team deployed it within minutes, how it expanded his product line, the ROI benefits and more.

Join us on Tuesday, February 14 at 3pm in Room Ford B on Level 3 in the Hyatt. Or, stop by Booth #104 to say hello.

2012 Carrier Gigabit Ethernet Market Predictions

By Mike Collado
December 31st, 2011

2011 saw the launch of SOLiD’s ClearLight ACCESS™ high-capacity distribution product which unlocks network capacity within an existing fiber plant for rural telecom providers. Since its launch, ClearLight ACCESS has been well-received at both industry events and by customers. We expect to duplicate and expand upon these successes in 2012.

And, now, on to our market predictions…

Enterprises will upgrade their WAN Edge to GbE from 10/100


Continued migration of Access transport to Ethernet over DWDM technology

With advantages that include extremely low latency, distance reach and secure connections, we expect strong growth of DWDM.

Also, the emergence of Ethernet has revived the wavelength services market as a number of service providers use waves to provision Ethernet circuits, and most 1 GigE and 10 GigE Ethernet circuits provisioned today are over dense wavelength division multiplexing (DWDM)
