The independent blog on spectrum policy issues
that welcomes your input on the key policy issues of the day.

Our focus is the relationship between spectrum policy
and technical innnovation.

Acceleration of Broadband Deployment by Improving Wireless Facilities Siting Policies

The title of this post is the title FCC used for today’s Report and Order on tower siting (presumably not “sitting” as one FCC announcement said.)

The discussed focused on the urgent need for wireless capacity and the related wireless infrastructure. WE FULLY AGREE!

But there were 2 key points that were not said, perhaps they would be awkward given the influence of the cellular establishment at FCC and in DC in general.

capacity
First, we have used this diagram from an Ofcom report several times although we have never seen a similar diagram in any FCC publication, let alone a CTIA one. Wireless capacity is a function of 3 different inputs: spectrum, technology, and “topology”/wireless infrastructure. Historically most of the increase in capacity has come from infrastructure growth, not spectrum increases. If you double the available spectrum for cellular carriers you may increase capacity by more than 2, but you will not increase it by a factor of 20. If you need a 10,000 fold increase in capacity you need a lot more infrastructure - that is why the issue is so important. But spectrum demands generally gets much more attention. Why?

NYC cell
Second, the discussion focused almost entirely on the problem being local governments that don’t appreciate how important wireless capacity is. For no rational reason, at least that was mentioned, do local governments question the proposed installations of the cellular establishment. Well, your blogger has a somewhat different viewpoint that has been stated here before: Too often cellular infrastructure looks like it was “designed by engineers” and does not consider the physical design of the immediate environment. Here is a pair of essays from your blogger and an industry engineer that discuss very different views on this issue. You decide.

Now the cell industry does sometimes due a good job in designing infrastructure to match its environment. Here are 3 examples of apparently modest cost installations that are reasonable design compromises. Note that in all 3 cases the covers/radomes of the antennas approximately match the surface they are mounted on; in addition there a no loose visually contrasting cables in these last 3 photos:

2 way
However, the unnecessary visual ugliness of the first photo is much more common than the good design of the next 3. If FCC and the cellular industry want local governments to be more cooperative, they should view cooperation as a 2-way street. Cellular infrastructure should more consistently consider its immediate environment as part of improving the interactions between the industry and local governments. Remember what Tip O’Neill famously said:

“All politics is local”

There is a limit how much the cellular industry can impose on local jurisdictions at the current ugliness levels without a grassroots political backlash. But well designed infrastructure need not be either ugly or very expensive. More consistent attention to physical design is urgently needed!

CTIA & PCIA: With SCOTUS Review of FCC "Shot Clock" Decision Pending Shouldn't You Have a "Plan B"

Shot-Clock-SCOTUS-pet
The U.S. Supreme Court on October 5, 2012 decided to hear a case brought by cities and counties across the country challenging the Federal Communications Commission’s authority to establish federal regulations governing local zoning of wireless cell towers. This FCC decision that is under consideration is commonly known as the “shot clock rule” and was adopted to facilitate the buildout of cellular infrastructure and limit the ability of local jurisdictions to draw out zoning and permitting.

shot clock
The CTIA website has been oddly silent on this issue. Since the Supreme Court’s decision to hear the case the only mention was a passage in the middle of an October 11, 2012 survey on data use when mention in passing:

Thanks to the Federal Communications Commission’s (FCC) 2009 shot clock ruling on tower siting, the number of cell sites continues to grow, which are key to providing wireless service in a geographic area. According to the semi-annual survey, there were 28,641 cell sites added this year for a total of 285,561 nationwide.


PCIA’s website and AT&T’s and Verizon’s policy blogs are also silent on the topic. Perhaps everyone is confident that the Supreme Court will uphold the FCC’s implementation of the shot clock rule - but then why did SCOTUS accept the case if it was so obvious?

Buildout of cellular infrastructure is the dominant source of wireless capacity growth despite the constant demands for new spectrum by the major carriers. This wireless capacity growth has numbers benefits for economic growth and international competitiveness. As Preston Marshall said recently at the recent Silicon Flatirons spectrum conference, if you increase mobile spectrum by 50% you basically increase mobile capacity by 50%, not 2000%. Thus timely buildout of infrastructure is key.

Why Does Infrastructure Have to Look Like it was “Designed by Engineers”?

cell antenna
Your blogger is proud to be an engineer and a “card carrying IEEE member”. Engineering is about more than making things that work and perform useful functions: it is about making system that meet size, weight, cost, user interface, and other constraints as part of their design. For cellular base stations that are installed in residential areas, design should include compatibility with the local environment. This is an issue rarely addressed by the cellular industry unless they get into a difficult zoning/permitting issue in which case they “throw money at the problem” and build artificial trees or customer structures such as church steeples t hide their antennas. These custom approaches are very expensive so they are rarely used.

Tip O’Neill famously said “all politics is local”. The cellular establishment no doubt feels that if they lose this case in the Supreme Court they can just pressure Congress to give them a more favorable law that avoids the problems of the present shot clock rule. Perhaps. But if Tip O’Neill is still correct, members of Congress may well be reluctant to pressure constituents to accept undesired cellular infrastructure in their immediate neighborhoods.

But perhaps the cellular establishment should listen to industry insiders like Previously I reported about the comments of Bechtel VP Jake MacLeod, when he stated at a 2009 FCC broadband hearing that “we have reached the end of the line for current design concepts (for cellular towers).” (Bechtel is a major builder of wireless infrastructure.) Or Alcatel-Lucent Wireless Division President Dr. Wim Sweldens who said

But we also have to be honest that in the mobile industry we are creating some problems. The mobile industry is actually contributing a fair amount to pollution...The mobile industry is also obstructing and cluttering our landscapes and cityscapes with more and more and bigger and bigger and uglier and uglier antennas and towers.


A major part of the opposition to infrastructure in suburbia is the inappropriate design that is normally used. If new design techniques could create the stealth bomber that could fly and be invisible to most radars, it is likely that a bold new design approach could develop new infrastructure designs that perform their intended function yet fit in better with their environment.

This was my point in point #5 of my suggested New Year’s Resolutions for the Cellular Industry - a set of topics that drew no interest from the intended audience.

So, CTIA and PCIA, you don’t have to call or contact me. But I sincerely hope that since an adverse SCOTUS decision in this case will hurt us all that you start thinking about a Plan B that does not just depend on lobbyists, but addresses the root design cause of your problem.

CTIA-on-antennas.
The images and text at right are from the CTIA website. Perhaps this is the visual design standard that the cellular industry thinks is appropriate for the American environment? If so, your blogger thinks this is a major contributor to the siting problem which is hurting everyone! The SCOTUS review of the shot clock decision may be a good opportunity to develop a real Plan B to get at the root causes of this problem rather than focusing exclusively on steamrolling local governments.

RF Globalnet Article on Cell Base Station Antennas and Their Environment

header_genesis

Last January RF Globalnet, a newsletter for wireless technology types, published an article entitled "Antenna Location Is Not An Architectural Decision: Antenna system design and placement is critical to proper system performance”, by Alfred T. Yerger II of Bird Technologies Group, a frequent contributor to the publication. Mr. Yerger argued that technical issues are the key one in antenna design and shows little interest in architectural issues. He states, “As you can imagine, much of this does not fit well with a landlord’s or building owner’s idea of where the antennas should be placed, or a tower owner’s desire to fill a particular space on the tower.”

This week RF Globalnet published my response to the Yerger article, “Consistency With The Architectural Environment Is A Key Issue In Practical And Pragmatic Cellular Antenna Engineering”. The key issue of the response is stated as

“The point of this essay is to emphasize that good engineering is more than about making systems that work in a nominal sense, it is about making systems work in the real world with real constraints such as cost, size, weight, battery life, and compatibility with their environment in the case of systems that are intrusive into their locations as many cellular base stations are. It is this engineering to meet practical constraints which is a key difference between engineers and physicists.”

My article ends with

“Mr. Yerger ends his article with, "Remember, antenna location is not an architectural decision!" Perhaps not, but in the real world, antennas and other engineered systems have to work in the environment in which they are placed. Being compatible with the local environment and acceptable to neighbors is part of that. The cellular operators and suppliers should start making some real efforts to examine base station design for suburbia from a fresh piece of paper and stop focusing on using products in today's catalogs unless forced to do a very expensive custom design. Alcatel-Lucent deserves praise for ‘thinking outside the box’ with their new concept (lightRadio™), whether or not it ever has a significant role. The rest of industry should rethink its current approaches, also.”


Readers are invited to read both articles and post here with their views of the proper role of architecture/city planning issues in antenna system design. All responses will be posted here subject to constraints similar to present broadcasting FCC limits.

Best wishes to all for a Happy Thanksgiving!

Alcatel-Lucent Tries a New Approach to the Cellular Tower Issue:
Hiring Engineers, not Lawyers

A major inhibition to the rollout of 3G and 4G services and to the creation of more wireless competition has been delay in getting the necessary local zoning and permits for tower construction. The insert at right comes from the CTIA website and presumably is indicative of what the cellular industry calls “good design”. Thus the industry is puzzled why anyone would want to question putting such installations in a neighborhood.

In a recent court filing CTIA stated,

Wireless technology – especially the advanced wireless broadband technology that is currently driving the infrastructure needs of wireless service providers – generates enormous benefits for businesses, consumers, and the economy as a whole, and is making important contributions to public safety. For that technology to achieve its potential, however, wireless service providers must be free to build their networks across the country.


What does the industry mean by “ must be free to build their networks “? In a recent article in a trade magazine, a major antenna manufacturer stated,

“In order to obtain the necessary site leases, landlords often want specific antenna locations or insist on identifying the locations themselves. These decisions are often made with minimal or no system engineering information and are sometimes based on purely aesthetic concerns: what location looks the best, or “I don’t want to be able to see the antennas from the street.” When antenna placement decisions are made in this manner — without proper engineering input and review — and then locked in through the site lease, there is often trouble ahead.”


Thus the viewpoint is that the first issue of base station design is the operation of the base station and the convenience to its designer. “Aesthetic concerns” appear to be topic for wimps.

Your blogger is proudly a “card carrying” engineer, yet he cringes at the sight of towers that “look like they were designed by engineers”. Good engineering is not only building systems that work, it is building systems that fit practical constraints like costs and compatibility with their location. Is neighborhood uglification a necessary part of our wireless future or is it a result of industry inattention in most cases?

Lest you think that this is the view of an eccentric consultant outside the mainstream, let me give you two quotes from mainstream industry players on the status quo of tower design. Previously I reported about the comments of Bechtel VP Jake MacLeod, at a 2009 FCC broadband hearing when he stated that “we have reached the end of the line for current design concepts (for cellular towers).” (Bechtel is a major builder of wireless infrastructure.)

In the past 2 weeks, Alcatel-Lucent has posted a video by Dr. Wim Sweldens, President, Alcatel-Lucent Wireless Division, a major industry supplier:


Before going into the technology he discussed, here is what this mainstream industry player has to say about the status quo:

But we also have to be honest that in the mobile industry we are creating some problems. The mobile industry is actually contributing a fair amount to pollution...The mobile industry is also obstructing and cluttering our landscapes and cityscapes with more and more and bigger and bigger and uglier and uglier antennas and towers.

And why is that?We as the equipment vendors are part of the problem. We create big hungry base stations that need to become bigger and hungrier as we add more technologies. We put big towers with antennas and more and more of them every day. And that model and those types of technologies can not continue as our industry grows....

We have discovered the capability of taking these power hungry base stations and take these big and ugly antennas and pretty much make them invisible.

Now clearly Alcatel-Lucent is trying to sell their new technology that has little or no field experience at this time. But I am proud of my alma mater, Bell Labs, for taking on this major design challenge to develop creative ways of building base stations without ugliness and even save energy at the same time. Let’s hope that the industry now objectively evaluates this and other new approaches to buildout rather than focusing excessively on legal battles.

Remember what Tip O’Neill, Chmn. Ferris’ mentor said, “All politics is local” - the basic reason why pressing local governments on zoning is a hard battle that is best avoided - even by multibillion dollar industries.

CTIA and SF: Round 3 - Antenna Aesthetics






The City of San Francisco and the CTIA crowd have opened a 3rd round in their struggle. SF is now considering the ordinance shown at left. CNET reports that “under the Personal Wireless Service Facility Site Permits Ordinance (PDF), introduced Tuesday by SF Supervisor John Avalos, antenna applicants would have to consider the visual impact of any new installations. The city could also reject applications based on that factor alone.”

Readers may recall that cellular antenna design and the resulting local opposition has been a topic here for a long time. We also described how cellular mainstream member Ericsson tried to make a bold approach in antenna design that got interest in other countries, but none here. Cellular establishment members apparently prefer to hire lawyers and press for “shot clocks” and attempts at zoning preemption than to address their fundamental design problem: Their preferred antenna designs are incompatible with most suburban locations and the only alternative they have are very expensive custom designs they only want to use when in desperation. Your blogger’s approach to PCIA, the trade association representing most tower owners, was met with polite disinterest.

Universities seeking funding for novel design projects pairing EEs with architects to “think out of the box” on such design have come up with no funding from this multibillion dollar industry with perpetual antenna siting issues.

Since CTIA has already announced it will boycott SF over the cell phone labeling issue, they don’t have that threat in their quiver anymore. I suppose they can put their 4 law firms to work and sue over this issue also.

Maybe CTIA and its major members just prefer dealing with lawyers than with fundamental design problems. Cellular communications is not just part of our day to day lives, its infrastructure is part of the urban and suburban landscape. Should the industry try to come up with more pragmatic designs? Recall that at an FCC broadband hearing last year Jake MacLeod, a Bechtel VP, also stated that “we have reached the end of the line for current design concepts.” If this is what major contractors of the cellular establishment are saying then maybe the SF government is not so off the mark.
