00:00:07
Today's guest on
2
:
00:00:09
MeteoScientific’s The Business of LoRaWAN
is Gavin Brown, an industrial designer
3
:
00:00:13
turned VP of strategic growth
and design partner at RAK wireless.
4
:
00:00:16
We talk about turning ideas
into real deployments.
5
:
00:00:19
Digging into gateways, antennas, RF design
and off grid LoRaWANs in the wild.
6
:
00:00:23
This episode is sponsored
by the Helium Foundation
7
:
00:00:25
and is dedicated
to spreading knowledge about LoRaWAN.
8
:
00:00:27
If you'd like to learn more
9
:
00:00:28
about the publicly available global
or when they run, visit helium.foundation.
10
:
00:00:32
Now let's dig into the conversation
with Gavin Brown.
11
:
00:00:37
Gavin,
thanks so much for coming on the show.
12
:
00:00:39
I'm psyched to have you here.
13
:
00:00:40
Thanks, Nikki. I appreciate the invite.
14
:
00:00:43
Yeah, it's super cool.
15
:
00:00:44
You're working over at RAK, and we talked
a little bit about what RAK does.
16
:
00:00:48
I'd known them
initially from my exposure via
17
:
00:00:51
helium back in 2020, maybe 2021.
18
:
00:00:54
But you were saying like, hey, it actually
does a lot more than folks think.
19
:
00:00:57
Can you walk me through maybe the 4
or 5 main pillars of what RAK does?
20
:
00:01:01
In a nutshell, it's
the LoRaWAN hardware stack.
21
:
00:01:05
I could probably simplify
that to a couple of pillars initially.
22
:
00:01:08
So gateways
23
:
00:01:09
the core to the networking business
and the tenant, the sector as a whole.
24
:
00:01:13
And modules.
25
:
00:01:14
Modules being ready to use stamp modules.
26
:
00:01:18
Some people call them for end devices
or end device development.
27
:
00:01:20
So it's it's both the,
28
:
00:01:22
the network side and the node side
is probably the key pillars.
29
:
00:01:26
There's a few more in between
that solutions and products that allow you
30
:
00:01:30
to implement those things
in those two domains
31
:
00:01:33
more easily, like services
and things like that.
32
:
00:01:37
I saw something about antenna design,
which I didn't know you guys did at all.
33
:
00:01:40
Is that true?
34
:
00:01:41
It's very true. Yeah. Okay.
35
:
00:01:44
Something which is very key to success
in this domain, that unfortunately,
36
:
00:01:49
the laws of physics apply to everything
we do, especially at radio and wireless.
37
:
00:01:54
So antenna design is something
we do as a service, support our customers.
38
:
00:01:59
And it's mostly focused
towards the node side of customer project.
39
:
00:02:04
Got it.
40
:
00:02:05
What does a typical customer look like?
41
:
00:02:06
I mean I know I've bought gateways
from you guys
42
:
00:02:08
and I've bought devices, but what is it?
43
:
00:02:10
And I'm sure
I'm not one dude in San Diego.
44
:
00:02:12
Your typical customer.
45
:
00:02:14
What what does a typical customer
look like?
46
:
00:02:16
I wish I had a good answer for that
because of the the varied stack
47
:
00:02:20
we operate along amongst, it's
massively varied.
48
:
00:02:24
But if if I could average out.
49
:
00:02:26
Typical customers are looking
for the path of least resistance
50
:
00:02:29
to adopt this technology
because it's key to their business,
51
:
00:02:34
their solution, a customer would have gaps
in their knowledge.
52
:
00:02:37
They would have, you know, some space
for momentum or lack of momentum.
53
:
00:02:41
And yeah, they would be picking RAK
just to sort of ease that journey.
54
:
00:02:45
Got it. Okay.
55
:
00:02:46
So they come to you and say, hey, you guys
are experts in this whole LoRaWAN thing.
56
:
00:02:49
Like, just fix this problem.
57
:
00:02:50
We have this problem.
58
:
00:02:51
Just fix it. Yeah.
59
:
00:02:52
And it could be, let's say network side.
60
:
00:02:55
They say, hey, I want an affordable
network solution gateways.
61
:
00:03:00
And I don't have the
62
:
00:03:02
deep networking background
I can just about set up the office Wi-Fi.
63
:
00:03:07
So okay no problem.
We have something for that.
64
:
00:03:09
Or we have somebody who wants to develop
a very affordable node
65
:
00:03:14
that can run for years on a battery
or some other, you know,
66
:
00:03:17
energy harvesting solution these days
and make that easy for me.
67
:
00:03:21
You know, I'm not a I'm not an expert
or a deep, you know, embedded
68
:
00:03:25
guy or a girl or whatever.
69
:
00:03:29
May God help me.
70
:
00:03:30
So we've got something
71
:
00:03:31
to cover that and we get everything
in between and a mixture of both.
72
:
00:03:35
Okay.
73
:
00:03:36
Yeah.
74
:
00:03:36
There's so many red RAK products
75
:
00:03:39
and you've got this background on
was industrial design is what you're into.
76
:
00:03:43
Yeah.
77
:
00:03:43
The core of my
my background is industrial design.
78
:
00:03:46
So I was an actual product
designer developer.
79
:
00:03:49
So I'm a little bit dangerous.
80
:
00:03:51
And a little knowledge
is a dangerous thing I should say.
81
:
00:03:54
Yeah. Got into hardware design also.
82
:
00:03:57
But my, my background is it was designing
physical and digital products
83
:
00:04:02
at scale actually in the consumer domain
and the professional domains.
84
:
00:04:06
And I bring that to RAK
and part of my role.
85
:
00:04:10
Right.
86
:
00:04:10
But it gives me a certain perspective
that allows me to help RAK as a business.
87
:
00:04:15
But obviously our customer. Yeah. Yeah.
88
:
00:04:17
I mean, you must because I do this and
I have no background in industrial design.
89
:
00:04:21
Do you ever look at IoT products and go,
oh God, that's a mess.
90
:
00:04:26
And then think about the development piece
where it's a blessing and a curse
91
:
00:04:30
because, yeah,
every every object tells a story
92
:
00:04:33
for those who can read it,
I suppose I can, I can read it.
93
:
00:04:37
Yeah.
94
:
00:04:37
So I understand the pain or the challenges
95
:
00:04:42
that were embraced or not,
you know, in something.
96
:
00:04:45
Yeah. So yeah, I look at things I don't
think, okay, I could have done better.
97
:
00:04:48
It's like I have great respect for that.
98
:
00:04:50
The difficulty that would have been
traversed to make that happen.
99
:
00:04:54
Okay. I'm much more judgy than you are.
100
:
00:04:57
I feel like I have things
such a piece of garbage,
101
:
00:04:59
but it sounds like you're much better
about saying, okay, I understand
102
:
00:05:03
the difficulties in bringing
maybe just an idea to to market.
103
:
00:05:07
Can you maybe
104
:
00:05:08
walk me through the that process
where someone comes to you with an idea
105
:
00:05:11
and then kind of what are the big steps
for those of us who don't know about this
106
:
00:05:15
industrial design and designing for scale,
what does that look like?
107
:
00:05:18
Maybe it's take a quick step back
and far is industrial design.
108
:
00:05:21
The definition varies
quite a bit within business circles.
109
:
00:05:25
Okay, I would want to just generalize it
110
:
00:05:27
right now
and say it's kind of a hybrid of art.
111
:
00:05:30
And design and engineering.
112
:
00:05:31
So in in Europe where I'm based,
industrial design
113
:
00:05:34
generally means
when an industrial designer would design
114
:
00:05:38
how the thing looks
and how it behaves, what it does,
115
:
00:05:41
but also they would engineer it.
116
:
00:05:42
So it's kind of it's a it's a hybrid role.
117
:
00:05:45
So yeah, what the process look like.
118
:
00:05:46
And embrace that as a skill set
no matter how you chop it up.
119
:
00:05:50
So if you if you wanted to chop it up
into different pieces, that's fine.
120
:
00:05:53
The process.
121
:
00:05:54
So the best process always
looks like looking at the problem
122
:
00:05:57
first and taking a step back,
that 30,000ft view
123
:
00:06:01
before you get into the,
you know, the three foot view.
124
:
00:06:04
Yeah.
125
:
00:06:04
Because a lot of the
the thinking and the, the engineering
126
:
00:06:09
difficulty and challenges
are best addressed at the beginning.
127
:
00:06:13
You embed them into the design strategy
128
:
00:06:16
before you get deep into the project,
129
:
00:06:19
because that will be more costly
and more painful later.
130
:
00:06:22
And what does that mean
in reality in this domain law one well,
131
:
00:06:25
it means you try to think of some examples
a product, it's too expensive.
132
:
00:06:30
It's the supply chain is not
133
:
00:06:33
sustainable, RF performance
is not good enough or something like that.
134
:
00:06:36
You know, it's a
those things are very hard to solve later.
135
:
00:06:39
So the process just is front heavy
136
:
00:06:42
really focusing on like figuring out
what the actual problems are.
137
:
00:06:47
And then once you have that problem
138
:
00:06:48
set really well defined,
it sounds like then you can
139
:
00:06:51
the design part is probably easier.
Yeah, yeah.
140
:
00:06:53
The more you can define in the beginning
the better.
141
:
00:06:55
Obviously it's unknown and the process
is iterative by its very nature.
142
:
00:07:00
And what where
where RAK stands in this process
143
:
00:07:03
with our customers is to to raise the flag
for that LoRaWAN piece.
144
:
00:07:07
And the radio piece as early as possible.
145
:
00:07:10
You know, obviously,
146
:
00:07:11
I can speak as a generalist,
you know, with
147
:
00:07:13
who is it with an industrial designer
hat on, but not within the RAK companies
148
:
00:07:17
like, hey guys, look, the end of the day,
you're doing IoT, large scale IoT.
149
:
00:07:23
You got to take these boxes to make
that work.
150
:
00:07:25
We're here to help you.
151
:
00:07:27
And we got a team,
you know, and let's work together.
152
:
00:07:30
Got it.
153
:
00:07:30
And are there common mistakes
that you see someone coming to you with?
154
:
00:07:33
With date, they're like,
hey, I've got this IoT project.
155
:
00:07:35
I heard about LoRaWAN.
156
:
00:07:36
You guys are the experts.
157
:
00:07:37
Like, here, I want this widget to work.
158
:
00:07:40
Do you see the same mistakes every time?
159
:
00:07:41
Like, do you guys never think about
what are X, Y, and Z?
160
:
00:07:44
That is a good question.
161
:
00:07:45
And there is one.
162
:
00:07:46
One strong answer.
163
:
00:07:47
Yeah, it's usually the RFP.
164
:
00:07:49
It's the wireless antenna integration.
165
:
00:07:53
We see some
some kind of jumping over that,
166
:
00:07:56
not giving it as much detail
as it needs to be given.
167
:
00:08:00
And then it can create some problems.
168
:
00:08:02
It's not always key to the the mission.
169
:
00:08:05
You know, sometimes
170
:
00:08:06
you know the the dependencies
on the wireless performance or whatever.
171
:
00:08:10
Pretty flexible.
172
:
00:08:11
But yeah, it's usually that's the piece.
173
:
00:08:13
People just jump over that
and it's kind of maybe it's too complex
174
:
00:08:16
or they just go, okay,
I want to do the bit.
175
:
00:08:17
I understand this bit.
176
:
00:08:18
So magic can should happen for me.
177
:
00:08:21
You know, it's it is magic button
but it has its,
178
:
00:08:24
you know, realities got it's understood
magic.
179
:
00:08:27
Okay.
180
:
00:08:27
So it sounds like
181
:
00:08:28
one of the biggest problems
or one of the biggest challenges
182
:
00:08:30
when a customer comes to you guys
and says,
183
:
00:08:32
hey, I've got this widget and
I want you guys to make it LoRaWAN ized,
184
:
00:08:36
it is to educate them on like,
hey, this is what that means,
185
:
00:08:39
and this is where we have to insert
the RF design piece into this process,
186
:
00:08:42
and it's probably much further upstream
than you might think.
187
:
00:08:46
Yeah.
188
:
00:08:46
So is if I lean back on my my
other kind of comment about the process.
189
:
00:08:50
Yeah.
190
:
00:08:51
Yeah, it is just getting all this thinking
as early as possible into the project
191
:
00:08:56
or the, you know, the business journey
and being flexible.
192
:
00:08:59
So the education piece
it just being aware of it.
193
:
00:09:02
Wireless is is a is a thing to think about
is key to the success.
194
:
00:09:06
But we live with this wireless stuff
every part of our lives.
195
:
00:09:10
We're hyperconnected
you know we talked about it.
196
:
00:09:13
We have our cell phones
and Wi-Fi, whatever,
197
:
00:09:16
and we all feel the pain
when it doesn't work.
198
:
00:09:20
Yeah, there's some glitches, some glitch,
some temporary downtime.
199
:
00:09:23
You know, I'm go through a tunnel
or whatever, you know, something happens.
200
:
00:09:26
So these are the realities
of all wireless stuff.
201
:
00:09:29
So the education pieces that's a thing
you can mitigate against it.
202
:
00:09:33
If you're smart with your design
strategy and implementation
203
:
00:09:37
you can have like success
like you never dreamed possible.
204
:
00:09:41
And we've got some really good
use cases to demonstrate
205
:
00:09:44
what we've had with customers.
206
:
00:09:45
Tell me about one. What
what can you give me an example there?
207
:
00:09:48
I can give you opposite
ends of the spectrum.
208
:
00:09:50
So yeah.
209
:
00:09:50
So we have one one customer
very large scale.
210
:
00:09:54
They deploy nodes in single sites.
211
:
00:09:58
I can't say too much.
212
:
00:09:59
It's in this sort of geography spectrum.
213
:
00:10:00
So domain they deploying 25 to 50,000
nodes in one area.
214
:
00:10:06
Holy smokes. Okay. Yeah.
215
:
00:10:07
So there's a lot of nodes in one place.
216
:
00:10:09
It's over like a 15 kilometer
by 15 kilometer area.
217
:
00:10:13
They needed a two kilometer range
from their node to succeed.
218
:
00:10:18
Okay.
219
:
00:10:19
They didn't didn't implement it very well.
220
:
00:10:20
They got like 700m.
221
:
00:10:22
Best case, cause them a lot of pain,
you know, a lot of pain.
222
:
00:10:25
And so that was kind of one
example of the, of the shortcomings
223
:
00:10:29
of not integrating.
224
:
00:10:30
Well, and it was just basically
electromechanical design
225
:
00:10:34
in the utility space.
226
:
00:10:36
And they had a node that was underground.
227
:
00:10:39
The antenna was designed in collaboration
228
:
00:10:42
in an, in collaboration with a manhole
cover, you know, a metal manhole cover.
229
:
00:10:46
Yeah.
230
:
00:10:47
And they, they guys are still
the craziest ranger I've ever come across.
231
:
00:10:52
But sort of our gateway
on the roof of their factory, four stories
232
:
00:10:57
kind of mostly line of sight,
but the forest and a few towns.
233
:
00:11:00
But they got 63km. Dang.
234
:
00:11:02
Because they're just
using the manhole cover
235
:
00:11:03
as some kind of antenna extension,
something like that.
236
:
00:11:06
It just has a system inside.
237
:
00:11:08
The deployment uses respect for the the
the technology and the system and design.
238
:
00:11:13
Well.
239
:
00:11:14
And the other one which was I have a node.
240
:
00:11:17
Here's my node is finished.
241
:
00:11:18
Oh somebody I got to put an antenna.
242
:
00:11:20
Oh I have a gap.
243
:
00:11:21
Put it in there.
244
:
00:11:22
So does the vast difference in capability.
245
:
00:11:25
But the commonality there is they're both
kind of ground level antennas you know.
246
:
00:11:30
So that's a similarity.
247
:
00:11:31
Just so there's a massive difference.
248
:
00:11:33
So one is very very good.
249
:
00:11:35
One is not very good. Yeah.
250
:
00:11:37
Borderline not very good.
251
:
00:11:38
But my point is borderline acceptable.
252
:
00:11:40
You know the
the requirements of that project.
253
:
00:11:42
We're not doing much anyway.
254
:
00:11:43
You know,
one two kilometers would be plenty.
255
:
00:11:45
But they just fell short of that still.
256
:
00:11:47
Oh, God.
257
:
00:11:48
Okay, so I'm not saying every
every project needs to be this massive,
258
:
00:11:51
you know, 50 kilometer,
you know, superstar thing, right?
259
:
00:11:55
Yeah. It's it's a it's a crazy thing.
260
:
00:11:56
I was one of the very first,
261
:
00:11:58
most attractive piece of LoRaWAN for me
was just how far it went.
262
:
00:12:01
And when I got into it,
it was through paragliders.
263
:
00:12:04
And so luckily for paragliders
you're always up high.
264
:
00:12:06
So the node is always,
you know,:
5000
265
:
00:12:09
So it's much easier to hit.
266
:
00:12:11
So the kind of 6060 K thing wasn't
an all the time, but it wasn't unusual.
267
:
00:12:15
But having got into this kind of ground
based sensor,
268
:
00:12:17
it's like a 6060
K is pretty unusual, very unusual.
269
:
00:12:21
But we do see some great,
great success stories.
270
:
00:12:23
So I'm champion.
271
:
00:12:24
I always champion
the technology from that point of view.
272
:
00:12:27
But obviously I have this bias
because my role within RAK
273
:
00:12:30
is 50% commercial, 50% kind of R&D.
274
:
00:12:34
I still keep so keep hold of my design.
275
:
00:12:37
I never let that go.
276
:
00:12:38
So I get to be at the coalface
277
:
00:12:41
and work with customers
and these use cases day in, day out.
278
:
00:12:46
So that's why I speak
so passionately about it,
279
:
00:12:49
because I get to see all these things
and help all these developers.
280
:
00:12:52
It's like the most fun job ever.
And it's pretty cool.
281
:
00:12:54
Yeah, I can't complain, I can't complain.
282
:
00:12:56
Do you have a favorite product
either in the RAK line
283
:
00:12:59
or maybe in general
that you're just like, oh,
284
:
00:13:01
this is one of my favorite pieces of IoT
hardware?
285
:
00:13:03
Yeah, that's a good question.
286
:
00:13:05
And it's what we would call the with Gate
Soho Pro,
287
:
00:13:09
which is a gateway and wireless gateway.
288
:
00:13:12
It comes in a small form factor enclosure.
289
:
00:13:15
It's around
kind of 30cm length by around 15.
290
:
00:13:21
And I thinking that's eight,
eight deep is an all in one box.
291
:
00:13:25
And all the antennas are built in
292
:
00:13:28
it's tiny form factor with a modular
293
:
00:13:32
mounting accessories solution
so you can mount it anywhere.
294
:
00:13:35
It's really convenient,
and that's pretty cool
295
:
00:13:37
because it's kind of a different approach
to your classic gateway
296
:
00:13:41
with all the antennas and cables
and stuff everywhere, which is necessary.
297
:
00:13:45
So that's probably one of my favorites
because of its neatness and its elegance
298
:
00:13:49
and the fact that it can blend
in, it can be invisible,
299
:
00:13:51
you know, in the environment.
300
:
00:13:52
And it's yeah, that is interesting.
301
:
00:13:54
I always I like the other side
because I like the big crazy antennas
302
:
00:13:57
and the wild wires,
like it made me feel like I did something.
303
:
00:14:00
But there is an impressive piece to how
small and clean and neat you can get
304
:
00:14:05
some really advanced piece of technology
that just does tons and tons of work.
305
:
00:14:09
So like got just a box in the wall, man,
that's not just a box on a wall.
306
:
00:14:13
No. When you've gone into the kind of
so you've got some respect
307
:
00:14:16
for the challenges there.
308
:
00:14:17
Because inside that product
we've got two Lora antennas, a GPS antenna
309
:
00:14:21
and a cellular antenna
all inside on Wi-Fi.
310
:
00:14:25
Only one box about this big.
311
:
00:14:27
You know, it has to do it, Lora thing
and everything else.
312
:
00:14:31
Yeah.
313
:
00:14:31
So that's a pretty cool,
pretty capable piece of equipment thread.
314
:
00:14:36
That's super cool.
315
:
00:14:38
And then as we wrap this thing up,
is there anything coming down the pipe
316
:
00:14:41
either for LoRaWAN in general
as an industry or for RAK where you're
317
:
00:14:45
like, hey, I'm seeing this thing coming
and I'm really pumped about it.
318
:
00:14:49
Something coming?
319
:
00:14:50
I was probably the strongest thread there,
and it builds upon something
320
:
00:14:54
we already have.
321
:
00:14:55
So we're very strong in the off
grid deployment solution.
322
:
00:14:59
So we have some very strong solar
off-grid battery solution,
323
:
00:15:04
which is key to many utility in large
scale deployments around the world.
324
:
00:15:10
And you
325
:
00:15:10
think about water metering, farming,
you know, a lot of off grid stuff.
326
:
00:15:14
We're struggling that
so more coming in that space.
327
:
00:15:17
Yeah. So more flexibility, more options.
328
:
00:15:20
We see a strong demand for off grid.
329
:
00:15:23
That's rad.
330
:
00:15:24
It does seem that that's where LoRaWAN is.
331
:
00:15:27
It's one of the kind of strongest pillars
is this ability to throw it up
332
:
00:15:29
almost anywhere.
333
:
00:15:30
And that it sends out
this bubble of coverage is the real hard
334
:
00:15:33
part is the backhaul back to the internet.
335
:
00:15:35
But that's getting solved with satellite
and everything else.
336
:
00:15:37
So it's it's pretty cool to see.
337
:
00:15:38
I should maybe extend on
that is one thing coming.
338
:
00:15:41
Is it actually is it is publicized.
339
:
00:15:43
But in the dimensions
of Non-terrestrial backhaul,
340
:
00:15:45
we actually have a gateway mesh solution,
which also helps solve that problem.
341
:
00:15:50
So we have that something we developed.
342
:
00:15:52
And that's a mesh solution
within the gateway
343
:
00:15:56
where you can have cellular connectivity
or traditional backhaul with one
344
:
00:16:00
or more gateways,
345
:
00:16:01
because the other gateway serving
your LoRaWAN network don't have backhaul.
346
:
00:16:05
So the mesh can hop between gateways.
347
:
00:16:07
So that's something we're seeing more
348
:
00:16:09
and more demand for
in the context of this solar deployment.
349
:
00:16:12
And we have for example, a good project
in and I'm based in the UK, but in Wales
350
:
00:16:17
we have to have what they call
the valleys is in the, you know, the
351
:
00:16:19
the mountainous region of Wales.
352
:
00:16:21
There's just no cellular coverage
353
:
00:16:22
and Non-terrestrial is quite,
not quite ready yet.
354
:
00:16:25
So we have the gateway mesh solution
with the solar deployed there.
355
:
00:16:29
So you know that's kind of
solving everything very cheaply.
356
:
00:16:32
You know, in very readily.
357
:
00:16:34
Yeah I Wales
Wales is near and dear to my heart.
358
:
00:16:36
I went to a climbing camp there
when I was a kid and it just
359
:
00:16:39
I'd heard about it.
360
:
00:16:40
It's like, oh,
361
:
00:16:41
you just think of the animal,
even though it's not spelled like that.
362
:
00:16:43
So it must be a boring place
when you drive through.
363
:
00:16:45
It's like, this is one of the most
beautiful places on Earth is red.
364
:
00:16:49
Yeah, well, there's parts of it
not very well connected, and it's just.
365
:
00:16:52
Just touches the physics of it, you know?
366
:
00:16:54
So that's why, you know,
why LoRaWAN really stands out there.
367
:
00:16:58
So yeah, there's a couple of things,
you know, they work hand in hand.
368
:
00:17:00
You know RAK is very modular
in terms of its products.
369
:
00:17:03
We you know we're agnostic.
370
:
00:17:05
You can you know, you pick as much of it
as you want or as little
371
:
00:17:09
as you want above our stack.
372
:
00:17:10
You know, we've got something for
everybody.
373
:
00:17:12
Just tools in the toolbox.
374
:
00:17:13
I'm always, always keeping an eye on
what you guys doing is always rad stuff.
375
:
00:17:16
Gavin, thanks
a ton for making the time to come on.
376
:
00:17:18
I know you're super busy
with designing stuff, making sure
377
:
00:17:21
RAK is going down the right place,
and having the empathy for product
378
:
00:17:24
development. So thanks for carving out
time from your day.
379
:
00:17:26
Thank to invite.
380
:
00:17:27
Yeah, really
appreciate it and had the fun taking part.
