FCC Requires Backup Power For 210K Cell Towers
1sockchuck alerts us to an article in Data Center Knowledge that explores ramifications from the FCC's decision a couple of months back to require backup power for cell sites and other parts of the telecom infrastructure. The new rule was prompted by wireless outages during Hurricane Katrina. There are more than 210,000 cell towers in the US, as well as 20,000 telecom central offices that will also need generators or batteries. Municipalities are bracing for disputes as carriers try to add generators or batteries to cell sites on rooftops or water towers. The rules will further boost demand in the market for generators, where there are already lengthy delivery backlogs for some models.
Yikes!
Check out my sci-fi/humor trilogy at PatriotsBooks.
I know a guy, he can get you all the batteries you want, alike the brade of your choice, at 1/5 the price!
Just -1, Troll talking to another.
Millions of people will be able to call each other to ask "is your power out too?"

The backup generators will probably not be very effective in preventing outages during natural disasters. Consider New Orleans: how many of generators can work while submerged underwater? Or California, where should an earthquake knock out the original power to a tower, it is just as likely to knock out the generator.

Maybe self powering solar paneled towers might be better. You'd be helping the environment as well as providing backup. And the height of these towers are perfect for a wind turbine + battery installation as well.
Even if it's not perfectly reliable, such a tower could be connected to the grid, and in the event of emergency, it'll be at the very least, intermittent,which is enough for some traffic to flow out for a very long time. With a battery/generator, you'd only have power, while reliable, for a limited amount of time.
During the east coast power failure a couple of years back, cell phones were useless because the towers were dead. Landlines worked just fine. I've always felt that the cell companies weren't doing enough to build out their infrastructure to support big events. They'd just have enough in place to provide average service.
Ma Bell and the landline service has been built out for generations and it shows.
I am a ham radio operator and concern myself with disaster preparedness. With POTS (plain old telephone system) everyone is guaranteed their own connection, complete with line backup power so you can use the phone even if the power's out. Sometimes the switches overload and "all circuits are busy" but in most situations it's worked pretty well for the last century.
I worry about the trend to move to cell phones. We rely on both our cell phone's battery and the cell tower to stay powered. We also rely on available frequencies to use the tower. In Katrina and recently the San Diego fires, everyone immediately got on their cell phones and jammed all of the towers. Is there enough redundancy, power, and capacity to handle the next disaster? I don't think we should wait for the next hurricane to prove if cell towers can handle an emergency.
I am currently in a power outage with NO Cellular Service (of any type)! This actually *sucks* and is inexcusable (considering what I pay!)
Those Damn Ice Storms here in the Central US (today and yesterday). (Generators/UPS are so so nice!)
Had Cell Service (with AT&T/Cingular) for about 3 hours following the outage (currently the largest single outage in my state's history)... but apparently the cell-site UPS batteries drained and the tower site did not have a generator...
I am going to ask for a prorated refund for my service plan (and they will legally HAVE TO give me that discount for my contracted service being out).
If EVERYONE called up their service providers and asked specifically for their prorated discount for service being out (on that given day)... I bet they would invest in UPS/Generator combos at the cell tower sites... -Z
EASY PICKINGS? In Texas and the nearby states like OK, KS, NM, etc, there are zillions of cell towers in the middle of nowhere. What an opportunity for thieves if these all had little generators nearby. I hope a better paradigm that what I describe is used.
NEW CASH COW? Its bad enough in Dallas where miles lights were out along the divided highways in the Summer of 2006 because thieves pulled out the connecting. This was bad in the summer of 2006 and its better now since openings have been welded shut. I can see generators being the new cash cow for thieves.

24 hours is sufficent to cover for brief, minor outages. It is not enough to cover for anything close to a natural disaster where many sites lose power and there are not enough resources to fix them all in 24 hours.
Here in New Zealand, all our telecom has 24 hour battery backup but it is sized "just right". Last year we lost power for approx 40 hours due to a severe snow storm. The phones lasted for appeox 25 hours.
Engineering is the art of compromise.
So you're saying for a worst case situation, where the batteries die, the generators are out of fuel, everything is down--and this solar panel or whatever sits there all day gathering sun and then at a predetermined time it runs the tower for 30 minutes so people can text their parents or whatever. Not bad idea, it would be extremely cheap to implement, and in the worst case scenario, it would continue to allow some communications. Coupled with fuel cell or hand-crank power for the cell phones themselves you could have a fairly reliable temporary 30 minute-per-day communication service.
Cool! Amazing Toys.
You're in a power outage posting to slashdot? Do you have a backup satalite link and generator just in case you lose internet for a few hours?
To provide solar power to a cell site would require several hundred square feet of space to mount the panels. Sizing a solar power system for infrastructure requires planning for when the amount of sun is at the minimum (approx 2 hours during wintertime at northern latitudes). A aolar system must put a full charge on the battery system to account for charging losses, battery inefficiency, and the continual demand of the load. To match up to a solar power system you need a very significant battery string (when I do system calculations I assume that the system can go for three days without sun). Mounting a wind turbine on a cell tower is problematic too. An antenna structure has a loading (ANSI 222 (f or g)) that has to account for ice, maximum wind and the surface area of the tower, feedline, antennas, etc... A wind turbine adds ALOT of loading to a structure. I suspect that 90% of the cell towers out there right now could not pass the structural analysis under ANSI.

Aww,,, Sniff, sniff. I co-manage 5 remote 2-way radio sites and, due to increased power needs, we have to upgrade the backup generator at one of our sites. Our primary electrical contractor quoted $38,000 for a COMPLETE installation: 35KW generator, transfer switch and installation.
And that's for ONE generator. The cellular folks will be buying them by the trainload and should be able to weasel a significant discount.
More crap! The electrical connections are the simplest part of the installation. Our contractor installs full-site transfer switches. They connect between the power meter and the disconnect switch or main fuse box. Two electricians do that part in under a day. The generator itself, OTOH, can take up to a week depending if there is a concrete base to be poured, fuel tank and EPA issues. Still, there's nothing new enough here to require "innovation".
Because the Communications Act of 1934 (and as ammended) requires the FCC to regulate telephone companies as part of Interstate Commerce.
Also because cell phones use radio frequencies, also regulated by the FCC.

Wireless Priority Services
- Became a high priority after September 11, 2001.
Extension of the U.S. wireline GETS system that had been around for many years.
Used the same call queuing approach.
Only available from GSM providers
- Only GSM has priority call identifiers.
Regarding hurricane Katrina:
I work for a large cell carrier. We had backup power to every single cell in the area. In fact, after the hurricane we were doing pretty well, though some of the towers were taken out by debris. Only a couple were actually submerged. We lost a few trunk lines, but for the most part the system was working.
The problem was we didn't have any way to get gas to the generators. The roads were impassible, and based on news reports we were reluctant to send crews in to the sites we could reach for security reasons. So after a couple days the cell sites started going offline one at a time as the generators ran out of power.
As far as I know every one of our sites, in the entire country, already has a couple days worth of backup power.
Electromechanical Batteries or EMB or Flywheel Batteries by their old name. These have the highest power density of any energy storage system. They are so reliable they can be buried or sent into space. They can hole huge amounts of power. They can be recharged very quickly. They do not burst into fire. They are not hazardous.
Specific Power EMB (5-10 kW/kg) Lead Acid (0.1-0.5 kW/kg)
Energy Recovery EMB (90%-95%) Lead Acid (60%-70%)
Specific Energy EMB (100 Wh/kg) Lead Acid (30-35 Wh/kg)
Service Lifetime EMB (>10 years) Lead Acid (3-5 years)
Self Discharge Time EMB (Weeks to months) Lead Acid (variable)
Hazardous Chemicals EMB (none) Lead Acid (Lead, Sulfur, & Acid)
"A new look at an Old Idea the Electromechanical Battery" Science and Technology Review April 1996 by
Dangerous EMB (possibly in massive physical impact) Lead Acid (High fire danger)
Caterpillar and Beacon power already sell off the shelf UPS based on EMB for anything up to a whole grid substation. These are the answer to balancing the output of solar and wind power as well, far better than ice batteries or lead acid. These are the answer to solving our reliability problems with the national power grid (if each substation could self power for even a few 1/10s of a second you can reroute the grid. In fact these are even a possible answer to batteries for cars thanks to new fiber based flywheels instead of steel. There is literally no sound reason to use Lead acid to backup a data center, a telephone switch, or a cell tower anymore.
The FCC should demand that the power backup meets a certain level of reliability and power density within a top percentile of the most cost effective solution so that people don't use old outdated technology just because it is a system that they are accustomed to.
