Chapter 3 Using GPS Navigation
DRAFT
Introduction
The MC55 includes Global Positioning System (GPS) technology using the SiRF III chipset. GPS technology is
based on a worldwide system of GPS satellites orbiting the earth that continuously transmit digital radio signals.
These radio signals contain data on the satellites’ locations and their exact clock time and are used to determine
your location on the earth.
WARNING! When using the MC55 in a vehicle, it is the user’s responsibility to place, secure and use in a
manner that will not cause accident s, personal in jury or property damag e or obstruct their view . It
is the responsibility of the driver to operate the vehicle in a safe manner, maintain observation of
all driving conditions at all times, and not become distracted by the device to the exclusion of safe
driving practices. It is unsafe to operate the controls of the device while driving.
Software Installation
Third-party GPS navigation softwar e is required. Evaluation software is available from various suppliers. For
example; VisualGPS, visit: http://www.visualgps.net/VisualGPSce/
If interested in purchasing GPS navigation software check with the GPS software vendor (before purchasing,
downloading, or installing any software) to determine that the application is compatible with the MC55. Refer to the
application’s user guide for application installation and setup information.
MC55 GPS Setup
The GPS-enabled MC55 uses Microsoft Windows Mobile 6, so the operating system automatically manages
access to the GPS receiver to allow multiple programs to simultaneously access GPS data.
Ensure that the following settings are set on the MC55 :
1. Tap Start > Settings > System > External GPS icon.
2. In the Programs tab, select None from the GPS program port drop-down list.
3. In the Hardware tab, select COM8 in the GPS hardware port drop-down list.

4. Select 57600 from the Baud rate drop-down list.
5. Tap ok to close the Setting window.
NOTE If an application error message appears indicating that the COM port cannot be opened, ensure that a free COM
port is selected in the
Operation
Acquiring satellite signals may take a few minutes. It is best to be outside and have a clear, unobstructed view of
the sky . Without a clear view, acquisition takes much longer and could resu lt in the MC55 being unab le to compute
the initial position quickly. When operating the device indoors access to the GPS signals may be limited or
unavailable.
NOTE When using a GPS navigation application, ensure that the MC55 does not go into suspend mode. If the MC55
suspends then the power to the GPS radio is removed. Upon resume the GPS receiver must reacquire a valid GPS
signal, resulting in a a delay of positional information.
GPS Maps on microSD Cards
GPS hardware port drop-down list.
GPS navigation software vendors may sell maps on microSD cards. If using a microSD card with the GPS
navigation software:
1. Remove the Memory Card Cover on the side of the MC55.
2. Insert the microSD card into the slot.
3. Replace the Memory Card Cover.
Answering a Phone Call While Using GPS
If you receive a phone call while using your GPS navigation software:
1. Answer the phone call by pressing the Answer button.
2. Once you end the phone call, press the End Call button to resume the audio on the GPS software.
NOTE Anytime you are using GPS on the MC55 and you receive a phone call, the audio on the GPS navigation software
is muted until you finish the call.
Losing the GPS Signal While in a Vehicle
GPS performance on the MC55 may be affected if the vehicle has thermal glass windows and windshields, which
can block the MC55 from receiving a GPS signal from satellites. To improve GPS signal strength, place the MC55
where there is a clear view of the sky . A direct line of sight is required between the MC55 and the GPS satellites to
access information from the satellites.
The Global Positioning System (GPS) is a system that allows the user to track their position anywhere on the earth.
Assisted GPS
GPS can be used in stand-alone or Assisted GPS (A-GPS) modes. A Stand-alone GPS receiver downloads data
from GPS satellites. It can take several minutes to get a fix. By using GPS Location servers, A-GPS dramatically
Using GPS Navigation 3 - 3
DRAFT
improves the performance of the Time To First Fix (TTFF) of GPS receivers by providing them with data that they
would ordinarily have to download from the GPS satellites. With the A-GPS data, GPS receivers can operate faster
and more reliably.
A-GPS follows the Secure User Plane Location (S UPL) protocol which allows a mobile device to communicate with
a location server. Refer to the EMDK Help file for information on setting up SUPL on the MC55.

Chapter 4 Using Bluetooth
DRAFT
Introduction
Bluetooth-equipped devices can communicate without wires, using frequency-hopping spread spectrum (FHSS)
radio frequency (RF) to transmit and receive data in the 2.4 GHz Industry Scientific and Medical (ISM) band
(802.15.1). Bluetooth wireless technology is specifically designed for short-range (30 feet/10 meters)
communication and low power consumption.
MC55s with Bluetooth capabilities can exchange information (e.g., files, appointments, and tasks) with other
Bluetooth enabled devices such as phones, printers, access points, an d other mobile computers. To use the MC55
as a modem, create a dial-up modem connection between a computer and MC55.
Motorola mobile computers with Bluetooth technology use the StoneStreet Bluetooth stack. To program Bluetooth
within the MC55 refer to the Enterprise Mobility Developer Kit (EMDK) Help.
Adaptive Frequency Hopping
Adaptive Frequency Hopping (AFH) is a method of avoiding fixed frequency interferers, and can be used with
Bluetooth voice. All devices in the piconet (Bluetooth network) must be AFH-capable in order for AFH to work.
There is no AFH when connecting and discovering devices. Avoid making Bluetooth connections and discoveries
during critical 802.11b communications. AFH for Bluetooth consists of four main sections:
•
Channel Classification - A method of detecting an interference on a chann el-by-channel basis, or pre-defined
channel mask.
•
Link Management - Coordinates and distributes the AFH information to the rest of the Bluetooth network.
•
Hop Sequence Modification - Avoids interference by selectively reducing the number of hopping channels.
•
Channel Maintenance - A method for periodically re-evaluating the channels.
When AFH is enabled, the Bluetooth radio “hops around” (instead of through) the 802.11b high- rate channels. AFH
coexistence allows Motorola mobile computers to operate in any infrastructure.
4 - 2 MC75 User Guide
DRAFT
The Bluetooth radio in this MC55 operates as a Class 2 device power class. The maximum output power is 2.5mW
and the expected range is 32.8 feet (10 meters). A definition of ranges based on power class is difficult to obtain
due to power and device differences, and whether one measures open space or closed office space.
NOTE It is not recommended to perform Bluetooth wireless technology inquiry when high rate 802.11b operation is
required.
Security
The current Bluetooth specification defines security at the link level. Application-level security is not specified. This
allows application developers to define security mechanisms tailored to their specific need. Link-level security
occurs between devices, not users, while applic ation-level security can be implemented on a per-user basis. The
Bluetooth specification defines security algorithms and procedures neede d to authenticate device s, and if nee ded,
encrypt the data flowing on the link between the devices. Device authentication is a mandatory feature of Bluetooth
while link encryption is optional.
Pairing of Bluetooth devices is accomplished by creating an initialization key that is used to authenticate the
devices and create a link key for them. Entering a common PIN number in the devices being paired generates the
initialization key. The PIN number is never sent over the air. By default, the Bluetooth stack responds with no key
when a key is requested (it is up to user to respond to the key request event). Authentication of Bluetooth devices
is based-upon a challenge-response transaction. Bluetooth allows for a PIN number or passkey that is used to
create other 128-bit keys used for security and encryption. The encryption key is derived from the link key used to
authenticate the pairing devices. Also worthy of note is the limited range and fast frequency hopping of the
Bluetooth radios that makes long-distance eavesdropping difficult.
Recommendations are:
•
Perform pairing in a secure environment
•
Keep PIN codes private and don't store the PIN codes in the mobile computer
•
Implement application-level security.
Turning the Bluetooth Radio Mode On and Off
DRAFT
Turn of f the Bluetooth radi o to save power or if entering an area with radio r estrictions (e.g ., an airplane). When th e
radio is off, other Bluetooth devices cannot see or connect to the MC55. Turn on the Bluetooth radio to exchange
information with other Bluetooth devices (within range). Communicate on ly with Bluetooth radios in close pro ximity.
NOTE To achieve the best battery life turn off radios not in use.
