Shownotes

Gavin Brown, VP of Strategic Growth and Design Partner at RAKwireless, talks about how solid industrial design and RF engineering turn LoRaWAN from a promising idea into reliable, large-scale deployments.

With a background in industrial design and product development, he explains how RAK’s core pillars—gateways, modules, and supporting services—give customers a path of least resistance into LoRaWAN, whether they’re building networks, nodes, or full end-to-end solutions.

Gavin digs into what typical RAK customers really look like: teams who know their own domain well but need help bridging the gap into wireless and LoRaWAN.

He describes industrial design as a hybrid of art, design, and engineering, and shows why the best projects are “front heavy,” putting RF constraints, cost, supply chain, and mechanical realities into the strategy before anyone obsessively sketches enclosures or PCB shapes.

That early thinking is especially critical for LoRaWAN, where antenna placement and housing can make the difference between pain and success.

He shares real-world examples, from a 25–50,000-node deployment that struggled with range because RF was an afterthought, to a utility project that achieved a 63 km link by respecting physics and integrating the antenna properly into a metal manhole cover.

Gavin also highlights some of his favorite RAK designs, including the compact WisGate Soho Pro gateway with fully integrated antennas, and explains how off-grid solar gateway solutions and gateway mesh backhaul are opening up LoRaWAN in remote regions like the valleys of Wales.

Throughout the conversation, he returns to a core theme: LoRaWAN works brilliantly when hardware, RF, and business goals are designed together, not bolted on at the end.

10

:

Now let's dig into the conversation

with Gavin Brown.

11

:

Gavin,

thanks so much for coming on the show.

12

:

I'm psyched to have you here.

13

:

Thanks, Nikki. I appreciate the invite.

14

:

Yeah, it's super cool.

15

:

You're working over at RAK, and we talked

a little bit about what RAK does.

16

:

I'd known them

initially from my exposure via

17

:

helium back in 2020, maybe 2021.

18

:

But you were saying like, hey, it actually

does a lot more than folks think.

19

:

Can you walk me through maybe the 4

or 5 main pillars of what RAK does?

20

:

In a nutshell, it's

the LoRaWAN hardware stack.

21

:

I could probably simplify

that to a couple of pillars initially.

22

:

So gateways

23

:

the core to the networking business

and the tenant, the sector as a whole.

24

:

And modules.

25

:

Modules being ready to use stamp modules.

26

:

Some people call them for end devices

or end device development.

27

:

So it's it's both the,

28

:

the network side and the node side

is probably the key pillars.

29

:

There's a few more in between

that solutions and products that allow you

30

:

to implement those things

in those two domains

31

:

more easily, like services

and things like that.

32

:

I saw something about antenna design,

which I didn't know you guys did at all.

33

:

Is that true?

34

:

It's very true. Yeah. Okay.

35

:

Something which is very key to success

in this domain, that unfortunately,

36

:

the laws of physics apply to everything

we do, especially at radio and wireless.

37

:

So antenna design is something

we do as a service, support our customers.

38

:

And it's mostly focused

towards the node side of customer project.

39

:

Got it.

40

:

What does a typical customer look like?

41

:

I mean I know I've bought gateways

from you guys

42

:

and I've bought devices, but what is it?

43

:

And I'm sure

I'm not one dude in San Diego.

44

:

Your typical customer.

45

:

What what does a typical customer

look like?

46

:

I wish I had a good answer for that

because of the the varied stack

47

:

we operate along amongst, it's

massively varied.

48

:

But if if I could average out.

49

:

Typical customers are looking

for the path of least resistance

50

:

to adopt this technology

because it's key to their business,

51

:

their solution, a customer would have gaps

in their knowledge.

52

:

They would have, you know, some space

for momentum or lack of momentum.

53

:

And yeah, they would be picking RAK

just to sort of ease that journey.

54

:

Got it. Okay.

55

:

So they come to you and say, hey, you guys

are experts in this whole LoRaWAN thing.

56

:

Like, just fix this problem.

57

:

We have this problem.

58

:

Just fix it. Yeah.

59

:

And it could be, let's say network side.

60

:

They say, hey, I want an affordable

network solution gateways.

61

:

And I don't have the

62

:

deep networking background

I can just about set up the office Wi-Fi.

63

:

So okay no problem.

We have something for that.

64

:

Or we have somebody who wants to develop

a very affordable node

65

:

that can run for years on a battery

or some other, you know,

66

:

energy harvesting solution these days

and make that easy for me.

67

:

You know, I'm not a I'm not an expert

or a deep, you know, embedded

68

:

guy or a girl or whatever.

69

:

May God help me.

70

:

So we've got something

71

:

to cover that and we get everything

in between and a mixture of both.

72

:

Okay.

73

:

Yeah.

74

:

There's so many red RAK products

75

:

and you've got this background on

was industrial design is what you're into.

76

:

Yeah.

77

:

The core of my

my background is industrial design.

78

:

So I was an actual product

designer developer.

79

:

So I'm a little bit dangerous.

80

:

And a little knowledge

is a dangerous thing I should say.

81

:

Yeah. Got into hardware design also.

82

:

But my, my background is it was designing

physical and digital products

83

:

at scale actually in the consumer domain

and the professional domains.

84

:

And I bring that to RAK

and part of my role.

85

:

Right.

86

:

But it gives me a certain perspective

that allows me to help RAK as a business.

87

:

But obviously our customer. Yeah. Yeah.

88

:

I mean, you must because I do this and

I have no background in industrial design.

89

:

Do you ever look at IoT products and go,

oh God, that's a mess.

90

:

And then think about the development piece

where it's a blessing and a curse

91

:

because, yeah,

every every object tells a story

92

:

for those who can read it,

I suppose I can, I can read it.

93

:

Yeah.

94

:

So I understand the pain or the challenges

95

:

that were embraced or not,

you know, in something.

96

:

Yeah. So yeah, I look at things I don't

think, okay, I could have done better.

97

:

It's like I have great respect for that.

98

:

The difficulty that would have been

traversed to make that happen.

99

:

Okay. I'm much more judgy than you are.

100

:

I feel like I have things

such a piece of garbage,

101

:

but it sounds like you're much better

about saying, okay, I understand

102

:

the difficulties in bringing

maybe just an idea to to market.

103

:

Can you maybe

104

:

walk me through the that process

where someone comes to you with an idea

105

:

and then kind of what are the big steps

for those of us who don't know about this

106

:

industrial design and designing for scale,

what does that look like?

107

:

Maybe it's take a quick step back

and far is industrial design.

108

:

The definition varies

quite a bit within business circles.

109

:

Okay, I would want to just generalize it

110

:

right now

and say it's kind of a hybrid of art.

111

:

And design and engineering.

112

:

So in in Europe where I'm based,

industrial design

113

:

generally means

when an industrial designer would design

114

:

how the thing looks

and how it behaves, what it does,

115

:

but also they would engineer it.

116

:

So it's kind of it's a it's a hybrid role.

117

:

So yeah, what the process look like.

118

:

And embrace that as a skill set

no matter how you chop it up.

119

:

So if you if you wanted to chop it up

into different pieces, that's fine.

120

:

The process.

121

:

So the best process always

looks like looking at the problem

122

:

first and taking a step back,

that 30,000ft view

123

:

before you get into the,

you know, the three foot view.

124

:

Yeah.

125

:

Because a lot of the

the thinking and the, the engineering

126

:

difficulty and challenges

are best addressed at the beginning.

127

:

You embed them into the design strategy

128

:

before you get deep into the project,

129

:

because that will be more costly

and more painful later.

130

:

And what does that mean

in reality in this domain law one well,

131

:

it means you try to think of some examples

a product, it's too expensive.

132

:

It's the supply chain is not

133

:

sustainable, RF performance

is not good enough or something like that.

134

:

You know, it's a

those things are very hard to solve later.

135

:

So the process just is front heavy

136

:

really focusing on like figuring out

what the actual problems are.

137

:

And then once you have that problem

138

:

set really well defined,

it sounds like then you can

139

:

the design part is probably easier.

Yeah, yeah.

140

:

The more you can define in the beginning

the better.

141

:

Obviously it's unknown and the process

is iterative by its very nature.

142

:

And what where

where RAK stands in this process

143

:

with our customers is to to raise the flag

for that LoRaWAN piece.

144

:

And the radio piece as early as possible.

145

:

You know, obviously,

146

:

I can speak as a generalist,

you know, with

147

:

who is it with an industrial designer

hat on, but not within the RAK companies

148

:

like, hey guys, look, the end of the day,

you're doing IoT, large scale IoT.

149

:

You got to take these boxes to make

that work.

150

:

We're here to help you.

151

:

And we got a team,

you know, and let's work together.

152

:

Got it.

153

:

And are there common mistakes

that you see someone coming to you with?

154

:

With date, they're like,

hey, I've got this IoT project.

155

:

I heard about LoRaWAN.

156

:

You guys are the experts.

157

:

Like, here, I want this widget to work.

158

:

Do you see the same mistakes every time?

159

:

Like, do you guys never think about

what are X, Y, and Z?

160

:

That is a good question.

161

:

And there is one.

162

:

One strong answer.

163

:

Yeah, it's usually the RFP.

164

:

It's the wireless antenna integration.

165

:

We see some

some kind of jumping over that,

166

:

not giving it as much detail

as it needs to be given.

167

:

And then it can create some problems.

168

:

It's not always key to the the mission.

169

:

You know, sometimes

170

:

you know the the dependencies

on the wireless performance or whatever.

171

:

Pretty flexible.

172

:

But yeah, it's usually that's the piece.

173

:

People just jump over that

and it's kind of maybe it's too complex

174

:

or they just go, okay,

I want to do the bit.

175

:

I understand this bit.

176

:

So magic can should happen for me.

177

:

You know, it's it is magic button

but it has its,

178

:

you know, realities got it's understood

magic.

179

:

Okay.

180

:

So it sounds like

181

:

one of the biggest problems

or one of the biggest challenges

182

:

when a customer comes to you guys

and says,

183

:

hey, I've got this widget and

I want you guys to make it LoRaWAN ized,

184

:

it is to educate them on like,

hey, this is what that means,

185

:

and this is where we have to insert

the RF design piece into this process,

186

:

and it's probably much further upstream

than you might think.

187

:

Yeah.

188

:

So is if I lean back on my my

other kind of comment about the process.

189

:

Yeah.

190

:

Yeah, it is just getting all this thinking

as early as possible into the project

191

:

or the, you know, the business journey

and being flexible.

192

:

So the education piece

it just being aware of it.

193

:

Wireless is is a is a thing to think about

is key to the success.

194

:

But we live with this wireless stuff

every part of our lives.

195

:

We're hyperconnected

you know we talked about it.

196

:

We have our cell phones

and Wi-Fi, whatever,

197

:

and we all feel the pain

when it doesn't work.

198

:

Yeah, there's some glitches, some glitch,

some temporary downtime.

199

:

You know, I'm go through a tunnel

or whatever, you know, something happens.

200

:

So these are the realities

of all wireless stuff.

201

:

So the education pieces that's a thing

you can mitigate against it.

202

:

If you're smart with your design

strategy and implementation

203

:

you can have like success

like you never dreamed possible.

204

:

And we've got some really good

use cases to demonstrate

205

:

what we've had with customers.

206

:

Tell me about one. What

what can you give me an example there?

207

:

I can give you opposite

ends of the spectrum.

208

:

So yeah.

209

:

So we have one one customer

very large scale.

210

:

They deploy nodes in single sites.

211

:

I can't say too much.

212

:

It's in this sort of geography spectrum.

213

:

So domain they deploying 25 to 50,000

nodes in one area.

214

:

Holy smokes. Okay. Yeah.

215

:

So there's a lot of nodes in one place.

216

:

It's over like a 15 kilometer

by 15 kilometer area.

217

:

They needed a two kilometer range

from their node to succeed.

218

:

Okay.

219

:

They didn't didn't implement it very well.

220

:

They got like 700m.

221

:

Best case, cause them a lot of pain,

you know, a lot of pain.

222

:

And so that was kind of one

example of the, of the shortcomings

223

:

of not integrating.

224

:

Well, and it was just basically

electromechanical design

225

:

in the utility space.

226

:

And they had a node that was underground.

227

:

The antenna was designed in collaboration

228

:

in an, in collaboration with a manhole

cover, you know, a metal manhole cover.

229

:

Yeah.

230

:

And they, they guys are still

the craziest ranger I've ever come across.

231

:

But sort of our gateway

on the roof of their factory, four stories

232

:

kind of mostly line of sight,

but the forest and a few towns.

233

:

But they got 63km. Dang.

234

:

Because they're just

using the manhole cover

235

:

as some kind of antenna extension,

something like that.

236

:

It just has a system inside.

237

:

The deployment uses respect for the the

the technology and the system and design.

238

:

Well.

239

:

And the other one which was I have a node.

240

:

Here's my node is finished.

241

:

Oh somebody I got to put an antenna.

242

:

Oh I have a gap.

243

:

Put it in there.

244

:

So does the vast difference in capability.

245

:

But the commonality there is they're both

kind of ground level antennas you know.

246

:

So that's a similarity.

247

:

Just so there's a massive difference.

248

:

So one is very very good.

249

:

One is not very good. Yeah.

250

:

Borderline not very good.

251

:

But my point is borderline acceptable.

252

:

You know the

the requirements of that project.

253

:

We're not doing much anyway.

254

:

You know,

one two kilometers would be plenty.

255

:

But they just fell short of that still.

256

:

Oh, God.

257

:

Okay, so I'm not saying every

every project needs to be this massive,

258

:

you know, 50 kilometer,

you know, superstar thing, right?

259

:

Yeah. It's it's a it's a crazy thing.

260

:

I was one of the very first,

261

:

most attractive piece of LoRaWAN for me

was just how far it went.

262

:

And when I got into it,

it was through paragliders.

263

:

And so luckily for paragliders

you're always up high.

264

:

So the node is always,

you know,:

265

:

So it's much easier to hit.

266

:

So the kind of 6060 K thing wasn't

an all the time, but it wasn't unusual.

267

:

But having got into this kind of ground

based sensor,

268

:

it's like a 6060

K is pretty unusual, very unusual.

269

:

But we do see some great,

great success stories.

270

:

So I'm champion.

271

:

I always champion

the technology from that point of view.

272

:

But obviously I have this bias

because my role within RAK

273

:

is 50% commercial, 50% kind of R&D.

274

:

I still keep so keep hold of my design.

275

:

I never let that go.

276

:

So I get to be at the coalface

277

:

and work with customers

and these use cases day in, day out.

278

:

So that's why I speak

so passionately about it,

279

:

because I get to see all these things

and help all these developers.

280

:

It's like the most fun job ever.

And it's pretty cool.

281

:

Yeah, I can't complain, I can't complain.

282

:

Do you have a favorite product

either in the RAK line

283

:

or maybe in general

that you're just like, oh,

284

:

this is one of my favorite pieces of IoT

hardware?

285

:

Yeah, that's a good question.

286

:

And it's what we would call the with Gate

Soho Pro,

287

:

which is a gateway and wireless gateway.

288

:

It comes in a small form factor enclosure.

289

:

It's around

kind of 30cm length by around 15.

290

:

And I thinking that's eight,

eight deep is an all in one box.

291

:

And all the antennas are built in

292

:

it's tiny form factor with a modular

293

:

mounting accessories solution

so you can mount it anywhere.

294

:

It's really convenient,

and that's pretty cool

295

:

because it's kind of a different approach

to your classic gateway

296

:

with all the antennas and cables

and stuff everywhere, which is necessary.

297

:

So that's probably one of my favorites

because of its neatness and its elegance

298

:

and the fact that it can blend

in, it can be invisible,

299

:

you know, in the environment.

300

:

And it's yeah, that is interesting.

301

:

I always I like the other side

because I like the big crazy antennas

302

:

and the wild wires,

like it made me feel like I did something.

303

:

But there is an impressive piece to how

small and clean and neat you can get

304

:

some really advanced piece of technology

that just does tons and tons of work.

305

:

So like got just a box in the wall, man,

that's not just a box on a wall.

306

:

No. When you've gone into the kind of

so you've got some respect

307

:

for the challenges there.

308

:

Because inside that product

we've got two Lora antennas, a GPS antenna

309

:

and a cellular antenna

all inside on Wi-Fi.

310

:

Only one box about this big.

311

:

You know, it has to do it, Lora thing

and everything else.

312

:

Yeah.

313

:

So that's a pretty cool,

pretty capable piece of equipment thread.

314

:

That's super cool.

315

:

And then as we wrap this thing up,

is there anything coming down the pipe

316

:

either for LoRaWAN in general

as an industry or for RAK where you're

317

:

like, hey, I'm seeing this thing coming

and I'm really pumped about it.

318

:

Something coming?

319

:

I was probably the strongest thread there,

and it builds upon something

320

:

we already have.

321

:

So we're very strong in the off

grid deployment solution.

322

:

So we have some very strong solar

off-grid battery solution,

323

:

which is key to many utility in large

scale deployments around the world.

324

:

And you

325

:

think about water metering, farming,

you know, a lot of off grid stuff.

326

:

We're struggling that

so more coming in that space.

327

:

Yeah. So more flexibility, more options.

328

:

We see a strong demand for off grid.

329

:

That's rad.

330

:

It does seem that that's where LoRaWAN is.

331

:

It's one of the kind of strongest pillars

is this ability to throw it up

332

:

almost anywhere.

333

:

And that it sends out

this bubble of coverage is the real hard

334

:

part is the backhaul back to the internet.

335

:

But that's getting solved with satellite

and everything else.

336

:

So it's it's pretty cool to see.

337

:

I should maybe extend on

that is one thing coming.

338

:

Is it actually is it is publicized.

339

:

But in the dimensions

of Non-terrestrial backhaul,

340

:

we actually have a gateway mesh solution,

which also helps solve that problem.

341

:

So we have that something we developed.

342

:

And that's a mesh solution

within the gateway

343

:

where you can have cellular connectivity

or traditional backhaul with one

344

:

or more gateways,

345

:

because the other gateway serving

your LoRaWAN network don't have backhaul.

346

:

So the mesh can hop between gateways.

347

:

So that's something we're seeing more

348

:

and more demand for

in the context of this solar deployment.

349

:

And we have for example, a good project

in and I'm based in the UK, but in Wales

350

:

we have to have what they call

the valleys is in the, you know, the

351

:

the mountainous region of Wales.

352

:

There's just no cellular coverage

353

:

and Non-terrestrial is quite,

not quite ready yet.

354

:

So we have the gateway mesh solution

with the solar deployed there.

355

:

So you know that's kind of

solving everything very cheaply.

356

:

You know, in very readily.

357

:

Yeah I Wales

Wales is near and dear to my heart.

358

:

I went to a climbing camp there

when I was a kid and it just

359

:

I'd heard about it.

360

:

It's like, oh,

361

:

you just think of the animal,

even though it's not spelled like that.

362

:

So it must be a boring place

when you drive through.

363

:

It's like, this is one of the most

beautiful places on Earth is red.

364

:

Yeah, well, there's parts of it

not very well connected, and it's just.

365

:

Just touches the physics of it, you know?

366

:

So that's why, you know,

why LoRaWAN really stands out there.

367

:

So yeah, there's a couple of things,

you know, they work hand in hand.

368

:

You know RAK is very modular

in terms of its products.

369

:

We you know we're agnostic.

370

:

You can you know, you pick as much of it

as you want or as little

371

:

as you want above our stack.

372

:

You know, we've got something for

everybody.

373

:

Just tools in the toolbox.

374

:

I'm always, always keeping an eye on

what you guys doing is always rad stuff.

375

:

Gavin, thanks

a ton for making the time to come on.

376

:

I know you're super busy

with designing stuff, making sure

377

:

RAK is going down the right place,

and having the empathy for product

378

:

development. So thanks for carving out

time from your day.

379

:

Thank to invite.

380

:

Yeah, really

appreciate it and had the fun taking part.

381

:

That's it for the show.

382

:

Thanks so much for listening.
