Base stations explained​

Judd Boaz profile image

By Judd Boaz​

Dr Sorell says phones or devices like iPads and smartwatches try to connect to the best mobile phone "base station".

This process can result in devices constantly looking for the best stations, to the point where they’re being a bit greedy, the professor says.

"It will constantly seek out the best service available," he says.

The doctor is getting deep into the technical aspects of base stations — how many antennas they have and the directions they’re pointed in.

"The base station is the piece of infrastructure, it has antennas on it, and those antennas provide for a radio connection," Dr Sorell says.

probably setting the scene for EP's phone pinging around the foraging areas. allegedly imo

Sorell says he provided a number of reports for the case. He says his focus for this case has been on Telstra towers.

He says mobile phones connect to the base station that has the best connection, which can change. He says:

The base station with the best service at the front of your house may be a different base station at the back of your house.
He says a base station typically involves three antennas which each point in directions “about 120 degrees apart”.

He says:

The antenna is now available to amplify that radio signal in a particular direction which means it’s able to improve its performance and provide that coverage, by design, to where that radio signal is needed.
The jury is shown a diagram of base stations around Korumburra.

How do phones connect to base stations?

By Kristian Silva

As this telecommunications masterclass continues, Dr Sorell reaches into his blue folder to retrieve a diagram of base stations from the Korumburra region.

Korumburra is the town near Erin Patterson’s home in Leongatha.

The diagram is shown to the court.

Five base stations are visible: Loch South on the far left of the diagram; to the centre are Holmes Hill and Korumburra; with Arawata and Kardella on the right.

Each of the stations have slightly different antenna setups, which the phones can connect to. But things like hills and buildings can be obstructive, leading to a phone choosing to pick a station that isn’t closest to it.

“The one that wins will be the one with the best quality signal,” he says.

Dr Sorell says if a phone is moving around, it may flicker back and forth between different base stations as it searches for a better signal.

If this was an accident and she had no idea they were dcm, what dried mushrooms was she using for sprinkling in all the kids stuff.
That would make them even more lucky to of not been poisoned, once from the leftovers and then the sneaky hiding in their food.
That's a great point Cartie. Do we know when she made the mushroom brownies? Potentially before the dehydrator purchase. Regardless, you could argue that she was experimenting with mushroom powder, what it tastes like it recipes without mushroom, whether it was detectable in any way. With regular, edible mushrooms of course because she wouldn't want her kids sick.

She apparently did not purchase the Sunbeam dehydrator until 28th April. So she either had a different one before that, or used a different method to dehydrate mushrooms before that (mushrooms can be dehydrated in an oven).


Arrange the mushrooms on drying screens and place in the oven. Prop open the oven door with a wooden spoon to vent steam. Dehydrate until leathery, 2 to 3 hours
Dried Mushrooms Recipe

April 28
The prosecution says Erin's mobile phone data suggests she travels to Loch before returning to Korumburra.
Two and a half hours later, Erin allegedly purchases a Sunbeam food lab electronic dehydrator from a Leongatha store.
The key people, timeline and evidence in Erin Patterson's mushroom murder trial
If she did not have a dehydrator until April 28th, yet was still able to dehydrate mushrooms, then one could say that there was a reason why she chose to buy one then. Right after having visited a location known to have death caps. 2 1/2 hours to be exact. It could just be a case of finding something like the oven method cumbersome and wanted to move onto something quicker & easier. Or, you could suggest that she had a plan, a plan to forage and dry death cap mushrooms. You would not want to put death caps in your regular oven, the one you cook family meals in, bake brownies for your kids etc. That can suggest a motive.

I'll remember to tell my dinner guests that the potatoes are home grown, the eggs were sourced from my sister's hen, the meat was sourced from the butcher down the road etc...
Shortened by me. In this case, I believe members of Simon's family, along with Simon and Erin, were known to regularly forage for mushrooms. I think they even did this together, like a family outing. If this was a shared activity, but even if they enjoyed the same hobby but alone, I would imagine this might come up during the meal. The meal was described as delicious by some of the guests, and I can imagine that could open up the conversation to where the mushrooms came from.

Imaginary potential conversation:
Guest #1: "This is delicious Erin, you're such a great cook"
Erin: "Thanks so much. I think it's all in the ingredients though. I foraged the mushrooms from XYZ Reserve, the place we foraged together last year. They grow in such perfect conditions there."

If guests share a common hobby, it wouldn't be odd to me to talk about that over lunch. Just like if I brought my car to a mechanic friend to diagnose a problem. If we shared an interest in cars, we might talk about how the diff needs replacing, the shockers are shocking and what our thoughts are on the latest model of XYZ and the fact it doesn't get great mileage. If not, I imagine the topic of conversation would be about the weather, how the kids are going, what they're doing on the weekend etc.

A brief history of telecommunication networks
K
By Kristian Silva

The cell coverage area of a base station is about 40 kilometres, Dr Sorell says.

In country areas, base stations are deliberately placed to provide signals to towns, on key roads or for wider coverage from hilltops.

The doctor launches into a quick history lesson, explaining how the old 2G networks were basically only for phone calls.

“Some of us remember those Nokia phones of the late 1990s, where you could make a phone call and that’d be about it,” he says.

With 4G and 5G, things are much more advanced and results in lots of records being generated that can be analysed.

Sorell is walking the jury through the map of the towers in the Korumburra area.

He says circles shown on the diagram do not indicate the area of the coverage.

Sorell says the red circle shows the mobile phone handset in question did connect to the antenna at some time.

But he says if the mobile phone connected to one antenna in isolation it is not possible to determine which direction the handset is in.

I bet they need the break!

User input not necessarily needed, expert says
Judd Boaz profile image
By Judd Boaz

Dr Sorell says that a person does not necessarily need to be using their phone for it to connect to a base station and transmit data.

He uses the example of a phone checking for new emails in the background, a task "over which, you as the user, really [have] no control".

"If a device is moving or travelling, what will happen to the connection?" the prosecution asks.

Dr Sorell explains again that phones will "handover" from one set of base stations as the phone travels, despite no interruption in service.

He says a data connection will show a record of these handovers.

Thanks for helping us out @MrJ ! :)

Also from the Skynews linked article:

"A close friend of the Patterson family told Daily Mail Australia she was known for going wild mushroom foraging around Victoria’s Gippsland region along with her ex-partner Simon and other relatives and was “very good” at it."
Skynews

I don't think this close friend of the family has been called up as a witness that I am aware of.
There was another report that I remember of a friend that said she had a library of mushroom books at her home:

The testimony from her daughter does not confirm any foraging hobby, but maybe she is too young:
"

Daughter says she has never been mushroom picking​

Tim Callanan profile image

By Tim Callanan​

The police officer asks Erin's daughter what her favourite food is and she replies "ice cream".

She is asked if, when she cooks with her mother, they ever used mushrooms and she says no.

Erin's daughter says she has never been mushroom picking with her mother and has never seen any wild mushrooms while out with her mother."
and from the son:

"Erin's son is asked if he likes mushrooms and he says he doesn't really like "how squishy and mushy" they are. He says he's never been foraging for mushrooms with his parents."

didn't her son say something about his mother taking photos of mushrooms one time? or was that someone else who said that

3. Erin's son recalled a walk "during COVID times" when his mother stopped to take photos of mushrooms "because they looked nice".
Yes, from the same media link:

"He remembers his mother once taking a photo of mushrooms when they were on a walk "because they looked nice" and it was "a very fond memory in his head".

This was around July or August, 2020 he says. He's not aware of his parents ever picking mushrooms.
"

I just do not understand why the reports to the media by these "friends" have not testified at the trial yet for the prosecution. Maybe it was incorrect reporting?

Could have been, maybe incorrectly reported, or maybe the prosecution just don't see it as worthwhile given she's admitted to picking the mushrooms
