If you've ever connected an external device
to your tablet or your mobile phone,
then you've had to go through the Bluetooth pairing process.
This is a security function that allows
you to control exactly what devices
are able to communicate to your mobile phone or your tablet.
This commonly requires you to view or verify
a particular phrase or personal identification number
to be assured that you're really connecting the device you
have in front of you.
This pairing process is something
you only have to do one time.
From that point forward, any time these devices
are together, they will automatically
connect and network with each other.
The process I'll give you in this video for Bluetooth
pairing is a very generic one, but each of the steps
may vary just a little bit depending
on the device you're using.
Make sure you check with the manufacturer
to understand the exact pairing process
and what buttons or settings you should configure to make sure
these devices can connect to each other
and communicate using Bluetooth.
The first step in the pairing process
is making sure that both devices are
configured to use Bluetooth.
Some devices, like a mobile phone,
allow you to disable the Bluetooth functionality.
So make sure that it's turned on on both of the devices
that you're pairing.
You'll then set the devices to a discoverable mode
so that they can be seen by each other.
And this may require a certain set of key sequences
on a Bluetooth device to put it into that mode.
For example, if you have a headset,
it may be holding a particular button or pushing a button
a number of times that puts it into this discoverable mode.
Once your device is in this discoverable mode,
it should show up on the list of available devices
for Bluetooth.
And there may be a number of devices on this list,
especially if you're in an area with a lot of Bluetooth
devices.
You'll want to choose the device you're
working with from the list of available Bluetooth devices
in your immediate area.
You'll then be prompted to either confirm
or to enter a personal identification number or pin.
This ensures that there is some security,
and you know exactly what devices you're
adding to your mobile phone.
And that's it.
You're now paired with your Bluetooth device.
And you can usually test connectivity at that point
to make sure that both of those devices
are able to communicate with each other.
Many of our mobile phones are communicating
to multiple satellites every day using GPS or the Global
Positioning System.
These GPS satellites were originally
created by the US Department of Defense,
and there are currently over 30 GPS satellites
in orbit around the Earth.
This allows us to get very precise navigation
from our devices.
And as long as our phone is able to hear the signals coming
from at least four of these satellites,
we can now get very precise information
about where we happen to be in the world.
Our phones are able to calculate where
we happen to be based on timing differences
from all of these different satellites.
We're able to calculate longitude, latitude,
and altitude of where we may be located.
We don't commonly see these signals
that we're receiving from a GPS satellite,
but we do see the results of these signals.
We commonly see this when we have maps
or when we need directions to a particular location,
and our phone can calculate exactly where
we are relative to where we need to be.
Our phones are also very smart in how
they gather information about where
we're located in the world.
And often GPS is one of those primary sources,
but our phones can also use Wi-Fi connectivity
and identify cellular towers in our area
to narrow down, more precisely, where we might happen to be.
In a large organization, you may be
responsible for managing all of these mobile devices that
are being used by employees of your organization.
One way to manage this is through the use
of a mobile device management solution or an MDM.
This means that you can manage all of the company owned phones
or any phones that users might own that they bring to work.
We call this Bring Your Own Device or BYOD.
This allows the manager of the MDM
to sit at a single console and gain access
to the configurations of all of the mobile devices
in their environment.
This is especially important if company data is
being stored on these devices.
We need some way to manage the security
and update the configuration settings of all
of those mobile phones and tablets.
If the manager wants to ensure that certain applications are
installed, the data is protected,
or that certain capabilities of the phone
are enabled or disabled, such as the camera,
you can do all of that using the MDM.
We commonly use our phones as one large storage device,
but when you have part of the phone being
used for personal use and part of the phone being used
for work use, you may want to use
an MDM to be able to partition out the company data
and protect that differently than the rest
of the private data on that phone.
This also means that if you need to delete or remove
any of that company data, you can
do that on the mobile device without affecting
any of the user's private data.
This might also be a good way to increase the security
of your mobile devices.
For example, you can use the MDM to manage
the type of access control that's
being used on a mobile phone.
For example, you may require that the screen automatically
lock after a certain amount of time
and that users are using a minimum
of a personal identification number to unlock the phone.
This can also make things very easy for the end user.
Instead of having the user manage the email configuration
and set up all of the detailed configuration
settings for that email, you can simply
push out the email configuration from the MDM.
The user doesn't have to configure or set up anything
on their mobile device.
And if changes need to be made later,
you can simply push those changes from the MDM console.
The MDM is also a good way to add enhanced security
to these devices.
For example, your security controls may require two factor
authentication on these devices, there
may be a personal identification number,
or you may require users to include biometrics when
they're unlocking the phone.
You might also use the MDM to push down
applications that are useful for two factor authentication.
For example, your company might use
a pseudo random authentication app
that provides a number that would
be used in conjunction with your username and password
each time you log into a service.
And of course, the MDM can control what applications are
available on that mobile phone.
There may be certain applications
that are required for you to use in the corporation.
And the MDM can ensure that those applications
are installed automatically on your phone.
The MDM can also be used to prevent certain applications
from being installed.
So if the security of this device is important,
you may have certain applications
that are restricted or forbidden from being installed
on your mobile device.
