Measured radiation levels from wireless
smart meters of different models and technologies

Abstract

The radio frequency radiation from four models of wireless utility electrical meters was measured.Three technologies were included:mesh smart meters, AMR and ERT meters.

It was found that the meters radiated most powerfully out through the front and less from the sides and back.

Some meters could clearly be measured more than 50 ft (16 meters) from the front plate, at levels above ambient.

The ERT meter did not transmit during the test period, as it only transmits when prompted by a radio signal.

Introduction

Wireless utility meters have become common in the United States.There are models available for measuring the use of natural gas, water and electricity for individual households, though the wireless electrical meters are the most common.The meters offer a variety of benefits, such as reduced cost of obtaining billing information.Some models also offer improved blackout detection, monitoring of power quality and load reduction during power shortages.

Some models transmit nearly continuously, while others transmit a few times a minute.Some older models transmit a few times a day or even just once a month.

Concerns and protests have been raised by the public in the last few years, based on numerous complaints from customers who claim health effects.There have also been protests from professional societies, such as the International Commission for Electromagnetic Safety (ICEMS) and the American Academy of Environmental Medicine (AAEM).

This report takes a look at the actual radio frequency radiation from four models of wireless electrical meters.

Methodology

The four meters were chosen to be far removed from other meters and other sources of interference.

The instrument used was a Tenmars TM-195 3-axis RF meter, which measures the frequency band from 50 MHz to 3500 MHz (3.5 GHz).All wireless electrical meters transmit within that range (usually around 900 MHz).

As the transmissions are not continuous, it was necessary to measure the peak value, instead of an average.According to Tenmars, the TM-195 instrument samples (measures) three times a second.As the pulsed transmissions from the wireless meters are of short duration (typically around 1/50^th second) it was necessary to measure over several minutes to make sure at least one burst coincided with the instrument’s sampling.The measurements were all 5 minutes or longer, with 5 minutes the common period.

The measurements were taken at varying distances from the front plate of the wireless utility meter.

Measurements were also taken at different angles from the front plate, to see if the radiation levels were the same in all directions.

The instrument was placed on a tripod, about 5 ft (1.3 meters) above the ground, to be level with the meter.

Measurements were not taken of the transients (“dirty electricity”) put on the household wiring, nor of power frequency (ELF) fields.

Results

The RF emissions from four electrical utility meters were measured.The meters were of three types:

•AMR “bubble up” meter (Itron/Schlumberger C1SR)

•ERT “wake up” meter (Elster AB1R)

•AMI mesh smart meter (Landis+Gyr Focus AXR and RXRS4e)

AMR “bubble up” drive-by meter

An Itron type C1SR meter was measured on a house in rural Arizona, several miles north of Tucson.The C1SR meter is also available under the Schlumberger brand.

This meter was owned by UniSource, one of the largest utilities in Arizona.UniSource owns the Tucson Electric Power utility, which operates in the area.

The C1SR meters can be programmed to communicate in various ways.This meter is programmed to transmit wirelessly every 30 seconds.¹A utility vehicle passes through the area about once a month to pick up the signals from the meters with a wireless receiver.The communication is one-way, the meters do not know when their signals are needed, so they transmit all the time.

In some areas around Tucson, the utility uses the same meters in a fixed network where the signals are received by collector units mounted on lamp posts.

The radiation from this C1SR meter was measured at increasing distances from the front plate, as shown in Table 1.

Table 1:C1SR meter frontal radiation

The radiation from the meter drops off with distance, but was still above ambient levels at twenty foot distance.

Measurements were also taken behind the meter, which was mounted on the wall of the house.This meant that the radiation had to pass through the steel breaker panel and the 12 inch (300 mm) thick wall.The wall appeared to be standard wood-framing, thus providing little attenuation.At 3 ft (1 meter) from the backside of the meter, the radiation level was measured to 8 mW/m².This is a 60 dB reduction from the same distance from the front side.

ERT “wake up” meter

An Elster AB1R meter was measured in a remote area of southeastern Arizona.The nearest town is Rodeo, New Mexico.

The meter is electromechanical with analog dials.Only a close inspection revealed that it was a wireless ERT meter, which the homeowner was unaware of.The meter has electronics mounted on the bottom of the mechanical meter, which can only be seen from underneath.A label indicates the ERT technology, and also lists an FCC notice.

ERT stands for Electronic Receiver Transmitter.These types of meters are read by a passing utility vehicle, which has a transmitter that sends out a signal.When the ERT meter receives this signal, it transmits its data.Otherwise, it does not transmit.

To verify that the meter was not transmitting, the RF instrument was placed 3 ft from the front plate.The peak value was measured to 0.0137 mW/m² over 12 minutes.

The ambient level was comparable (0.0099 mW/m²).

AMI mesh smart meters

Mesh smart meters are a part of a sophisticated wireless network.The meters constantly communicate with each other to detect if any of the meters are malfunctioning and to pass along messages in a relay fashion.The network is controlled by special collector units, which gather up the information from all the meters in the area and pass it on to the utility.

Mesh networks are very busy.Court-ordered disclosures reveal that for one brand of mesh network, each meter transmits an average of about 10,000 times a day, with some meters transmitting as much as 190,000 times a day².

Two different models of mesh smart meters were measured in the Dallas, Texas area.Both were of the Landis+Gyr brand, and using that company’s Gridstream mesh technology, according to the labels on the meters.

The first meter was located in a park in Hickory Creek, on the northwest side of the Dallas metro area.A wireless collector unit was found on a lamp post, about half a mile from the smart meter.

The meter was a Focus AXR model, which is identical to the Focus AXR-SD, but without a built-in disconnect switch.

The measurements were performed on two consecutive days (April 30 and May 1, 2012).The results are shown in Table 2.

Table 2:Hickory Creek Focus AXR mesh, frontal radiation

All values are peak.

The measurements were taken in the early evening on both days and are consistent.The radiation levels reach the ambient levels at a distance of about 100 ft (32 meters) from the front of the meters.

The ambient levels varied significantly over time.On Day 1, the ambient level was apparently lower when the 100 ft measurement was performed, than when the official ambient level was measured.On Day 2, the level was measured to be 30 times lower.This may be due to the varying traffic on the cell towers in the area.

The radiation levels were measured at various angles relative to the front, to see how directional the transmitter is.The measurements were taken 10 ft (3 m) from the meter, as shown in Table 3.

Table 3:Hickory Creek Focus AXR mesh, angular measurements

The antenna is clearly directional, with the radiation falling off rapidly to the side and back.At a 90 degree angle and beyond, the level is reduced by about 50 decibels.

The meter was mounted on a steel box, which could provide shielding towards the back, but not the side, which was glass.

A Landis+Gyr RXRS4e mesh smart meter was measured in a rural area near Seagoville, on the southeast side of the Dallas metro area.This model meter can be configured with various communication technologies, such as telephone modem, power line carrier (PLC) and wireless.According to the label, it used Gridstream Mesh wireless.

A collector unit was found on a lamp post about a mile away.It is possible that another unit was closer, but not found.

Measurements were taken from the front and side of the RXRS4e meter, as shown in Table 4.

Table 4:Seagoville RXRS4e mesh

All values are peak.

The radiation levels on the RXRS4e mesh meter were somewhat lower than the AXR meter at Hickory Creek.The reduction towards the side was also less (only about 50%).

It was not feasible to measure the radiation level from the back of this meter.

Discussion and conclusion

Three different wireless technologies are represented by four different models of meters.

As the meters do not transmit as a continuous wave, the peak values were collected.Readings were taken at varying distances to ensure that the values were true and not affected by the ambient levels.

The peak radiation levels were recorded for periods of at least 5 minutes, and no more than 12 minutes.

These peak levels varied between the models, with the C1SR being the lowest at 0.7 mW/m² and the Focus AXR the highest with 34 mW/m² at 10 ft (3 meters) distance.The C1SR may transmit less powerfully as its signal is received from a passing utility vehicle and there is no need for reaching much of a distance.

The C1SR meter transmits every 30 seconds, while the more powerful mesh meters transmit more often than that, sometimes multiple times a second.The peak recordings in this study only determined the strength of each pulse and are not affected by how frequently the meters transmit.The exposures from the mesh meters may thus be much greater, but cannot be quantified from this data.

All measurements were taken in rural or semi-rural areas, to limit interference from other transmitters.That the readings were higher than the ambient levels, and that they tapered off with increasing distance, indicates that there was no interference.The readings are thus credible.

It is possible that wireless meters deployed in more densely populated areas radiate less powerfully, though with meters placed closer together, the overall effect may be higher.This would especially be the case with apartment buildings and strip malls, where several meters may be mounted close together.

This study reveals that the meters do not radiate uniformly in all directions.The three meters tested radiated most powerfully out the front.In one case, a person standing 10 ft (3 m) from the side of the meter would receive a lower dose than someone standing 50 ft (16 m) from the front.

The ERT meter was found to not radiate any radio frequency when it was not prompted to do so.This type of meter is typically read monthly, but does not offer any of the functionalities needed for the smart grid.It is solely a labor-saving device and largely considered obsolete.

The ambient peak RF levels measured ranged from 0.0099 mW/m² in a remote part of Arizona to 0.6 mW/m² in a park on the outskirts of the Dallas metro area.A single wireless smart meter can raise the radiation level above the ambient for a distance of 50 feet (16 m).

Worried about the security of the Smart Grid? You should be. Security researchers warn that the Smart Grid could become a hacker's playground. As proof, here are four ways the Smart Grid can be hacked.
Technology Review has an excellent article outlining ways in which the Smart Grid is vulnerable. Here, based on the article, are four ways it can be hacked via the smart meters that will be in businesses and people's homes.
Attack Smart Meter RAM
The article says that security researcher Travis Goodspeed warns that attackers will be able to hack directly into smart meter RAM, and by doing that, get free reign. It sounds a little James Bond-ish, but here's how the articles claims says it can be done:

If the meter hasn't been built with protective features, a hacker can use syringes to insert a needle into each side of the device's memory chip. The needle serves as a probe to intercept the electrical signals in the memory chip. By analyzing these signals, the hacker can deduce the device's programming. Even if the meter includes security features, he says, it may be possible to extract the information using customized tools.

Hack the Meter's Digital radio
Godspeed says a similar technique to RAM-hacking can be used to get command of the smart meter's radio, and from there, launch attacks on the grid itself. Here's what the the article says:

The smart meter's two-way radio chip allows the device to be read remotely and to receive commands over the network. The software in the chip contains security codes that an attacker who's cracked the meter's programming can use to get on the network and begin issuing commands. Goodspeed has shown that the codes can be extracted using syringes in a process similar to the attack on the memory.

Hack the Meter Wirelessly
The article says that David Baker, director of services for security firm IOActive, warns that hackers can get into the meter via its wireless networking device for communicating with the network:

An attacker can use a software radio, which can be programmed to emulate a variety of communications devices, to listen in on wireless communications with the network and deduce over time how to communicate with the meters. Another method, Baker says, is to attack the hardware. An attacker could steal a meter from the side of a house and reverse-engineer it. This method, he says, while inexpensive, does require a good knowledge of integrated circuits.

Spread Malware Throughout the Network
Baker says that once someone has gotten access to a smart meter's programming, he could easily launch a worm or other malware to attack the network itself, other smart meters, and other devices attached to the grid. In fact, Baker has already demonstrated that it can be done, the article says:

Focus Axr Sd Meter How To Read

To demonstrate his attack, Davis crafted a piece of malware that could self-replicate to other meters, allowing an attacker to shut them down remotely. In simulations, Davis showed that if his worm were released in an area where all the houses were equipped with the same brand of meter, the worm could spread to 15,000 homes in the space of 24 hours.
