In a World of MeshAll you ever wanted to know about Mesh Networking

MESH• Starbucks, or a Hotel and wondered how do I get on the network and

how can I print to my printer? Then you just experienced the complexity of a Mesh Network. This webinar will talk about the most common network available to everyone, the Mesh Network. We will talk about what a Mesh Network is, how it functions and how it compares to other various network types. Lastly this session will cover some basic ways to setup your own MESH Network at your library. In some instances, you may have already set one up and didn’t even know it.

What’s on the Agenda?• What the heck is a MESH??• So I need Wires to make MESH, Right?• What am I going to do with all this MESH?• I got this! Now hook me up with the Geek Speak!• OK I did the MESH Thing Now what?

What the heck is a MESH??

Questions?

Do you know if you already use a MESH?

OK I did the MESH Thing Now what?• If you use DropBox, OneDrive, Google Apps, Email, etc? Then you

have already used a MESH network.• A MESH network is what connects you to internet based services.• It also connects you to other people & devices.• Its how a hacker can access your computer at home.• Its how you can send an email to a loved one.• Its how you can go onto Facebook and Post what you ate for dinner last night.

What the heck is a MESH??• The Internet: The Original MESH Network• “The Internet is the world’s largest MESH network. Information travels

across the Internet by being bounced automatically from one router to the next until it reaches its destination. The Internet is often depicted as a “cloud” or “web” of connectivity because of the billions of potential paths across which data can travel.”

What the heck is a MESH??• A way for two or more network

devices to talk to one another• The network design is one when

each device communicates as well as relays data to other devices on the network.

What the heck is a MESH??• There are many ways for

computers to talk called Topologies.• Fully Connected• Bus• Star• Ring• Mesh

• End goal for devices to talk

What the heck is a MESH??• A MESH network means every device has a point to point link• Its one type of network used for the Internet of Things devices talk to

one another• Phone & WANs• Connects STAR networks

What the heck is a MESH??• Its advantages over other Network types

is:• Uses dedicated paths to prevent traffic jams

on your network.• Its provides detours when paths are broken• Its private and secure• Easy to troubleshoot

So I need Wires to make MESH, Right?

So I need Wires to make MESH, Right?

How are you accessing your Internet services?

So I need Wires to make MESH, Right?• In Short NO…• MESH networks no longer

require Wires• There are tons of different

ways to communicate• Radio Waves• Wireless• Infrared

So I need Wires to make MESH, Right?• Evolution of network has

open communication over wireless networks• Cellular Devices & Towers• Evolution of networks for

far rural areas• Installation of Wireless

Repeaters

So I need Wires to make MESH, Right?• Wireless Mesh Networks are Economical.• LOOK!!! NO WIRES MOM!!

• They are a Key technology for next-generation wireless networking.• Can easily, effective and wirelessly connect entire cities using

inexpensive, existing technology.

What am I going to do with all this MESH?

What am I going to do with all this MESH?• SURPRISE!!! You’re already using

one! • MESH networks connect the world

together• It starts with your STAR network at

your work or home• It Connects to a MESH that

connects to another STAR

What am I going to do with all this MESH?

What am I going to do with all this MESH?• Your Home Network and

Employer Network is usually on a STAR network• If the central point goes down

the entire network goes down.• If all works the Central Point

talks to the MESH network. “The INTERNET”

What am I going to do with all this MESH?• If a link in the MESH goes

down, your network can connect to others.• Sending an email from

your network follows this same path.

I got this! Now hook me up with the Geek Speak!• The Geek Definition:• “A mesh network is a network that employs one of two connection

arrangements, full mesh topology or partial mesh topology. In the full mesh topology, each node is connected directly to each of the others. In the partial mesh topology, nodes are connected to only some, not all, of the other nodes.” – [TechTarget and Telecom Glossary 2k Definition]

I got this! Now hook me up with the Geek Speak!• There are three types of Wireless MESH Networks• Infrastructure Wireless Mesh

• Form an infrastructure for clients• Client Wireless Mesh

• Client nodes perform actual functions of network. The Routing and Config functions.• Hybrid Wireless Mesh

• Mesh clients perform Mesh functions with other Mesh Clients as well as accessing network

• Wireless Mesh networks still leverage networking technologies of 801.11a, b, g, n, and ac. This technology is useful for Non-Line-of-Sight (NLoS) network configurations.

I got this! Now hook me up with the Geek Speak!

I got this! Now hook me up with the Geek Speak!• To transmit data on any network it uses a Packet• A network device is connected to a Switch or Hub• This Switch/Hub is connected to a Router which communicates to the

larger network• Wide Area Network (WAN) is the MESH• This connects into another router that leads into another STAR

network

I got this! Now hook me up with the Geek Speak!• Desktops & Laptops

are wired into network• Laptops & Mobile can

be wireless into LAN• LAN connects to

Internet

OK I did the MESH Thing Now what?

OK I did the MESH Thing Now what?• Mesh networks can be implemented in many areas, business segments,

etc.• Developing Countries• Solar-Powered nodes are connected to cellular or satellite internet.

• Isolated Locations• Series of Wireless nodes connected to wired access point

• Education• Implementation to eliminate burying cables between buildings

• Healthcare• Nodes sent signals short distances to ensure access in every room

OK I did the MESH Thing Now what?• The Future of MESH• US Military foresees microchip-size devices that can be used on

battlefields for scouting and surveillance• Carmakers and telecom companies working to develop Intelligent

Transport Systems (ITS)• Street & Highway based MESH networks.• Using cameras and in-car sensors

OK I did the MESH Thing Now what?

OK I did the MESH Thing Now what?

OK I did the MESH Thing Now what?• How do you setup your own MESH network in the Library?• The Shopping List:• At least 3 to 4 Routers/Switch (Linksys or Netgear Cheap ones will work)• Laptops/Computers to connect into the routers• Configure Routers with different IP’s

• 192.168.1.1• 192.168.2.1• 192.168.3.1• 192.168.4.1

OK I did the MESH Thing Now what?• Connect machines to each of the

routers.• Configure the routers to accept to

allow two-way communication through the WAN port.
