Retractable cell tower installation idea

The idea is that you can put the cell tower in a protective mode. So when the strong winds has disappeared you tell the tower to get operational again. In the link to the pdf I suggest you might get the cell tower into a protective mode simply by retracting it underground.

  1. The structural desing of a tower able to retract into the ground or to telescope to a lower elevation would be significantly more costly than a conventional structure designed to withstand design wind loads.

  2. An interesting idea, but I can't see any cell phone company voluntarily cutting off any of their subscribers by executing this preemptive move for fear of being sued for breach of contract. This is especially true since most cell towers hole antennas for multiple companies.

  3. Although public safety regularly use cell phones, smart phones, and other commercial wireless devices and services as a secondary form of communications, these devices and systems are currently not sufficiently suited for public safety mission critical voice communications during critical incidents.Public safety officials cannot depend upon commercial systems that can be overloaded and unavailable. Experience has shown such systems are often the most unreliable during critical incidents when public demand overwhelms the systems.Public safety officials have unique and demanding communications requirements. Optimal public safety radio communications require:Dedicated channels and priority access that is available at all times to handle unexpected emergencies.Mission-critical one-to-many group capability, a feature not available in today’s commercial cellular systems.Highly reliable, secure, and redundant networks under local control that are engineered and maintained to withstand natural disasters and other emergencies.The best possible coverage within a jurisdictional area, with a minimum of dead zones – even in areas where commercial cellular services are not economically viable. And, unique, ruggedized equipment designed for quick response in emergency situations. First responders must not be forced to dial, wait for call connections, or get busy signals when seconds mean the difference between life and death!

  4. I think there is emerging technology that substitutes tall towers with arrays of antennas that are about the same height as street light poles.

  5. Sorry to try to introduce physics to this discussion but at the frequencies used for cell phones the propagation is effectively line of sight. The simple fact is that the range covered by a cell site is proportional to its height. In urban areas nearly all cell providers use micro-cells which use short towers (40-50') or antennas mounted on top of tall buildings. These cell sites cover a much smaller area than the tall (100-200') towers used in rural areas. This system works because the number of customers that can be served by any one cell site simultaneously is the same whether it is a micro site covering a few blocks or an old style tall tower covering many miles.

    In urban areas most cell "towers" are low enough and strong enough to withstand anything short of a tornado. The antennas may be damaged but the towers themselves generally survive. The loss of cellular service after a storm is more often due to a loss of electrical power (cell sites have backup power for a very short period) or because the connection between the cell system and the actual telephone system is knocked out.

    Changing to telescoping towers for cell sites would be prohibitively expensive for very little gain -- and completely unacceptable to the public in that it would mean the complete loss of cell service immediately prior to any major storm.

    All the assorted "innovative solutions" to the "problem" of cell phone service following a disaster are pipe dreams at best. Most proposals are not physically possible and those that are possible are prohibitively expensive -- and all are based on the false premise that there is some "need" for everyone to have instant communications so they can post a disaster selfie to facebook minutes after the disaster strikes.
