Q: How does the GPS in CN51 compare to CN50/CS40?
A: The GPS receiver function in the CN51 is similar to the
implementation in CN50 and CS40. It can operate in either
standalone or assisted mode. Standalone mode does not
require the user to have a data plan for the WWAN radio,
though it does require the WWAN radio to be powered up. The
assisted mode works by automatically downloading ephemeris
data in the background periodically in order to maintain its
table of satellite locations. This reduces the time required for
the GPS to achieve its first fix. The assistance mode is optional
and may be turned off to avoid data charges.
Q: How does the customer switch the WWAN radio between
network operators with the Flexible Network radio option?
A: The Flexible Network Radio option is ideal for customers who
desire to switch easily between UMTS to CDMA carriers "on the
fly". Switching network operators may be accomplished in
several ways:
1) Manually via the Carrier Selection application, accessed via
the Windows Embedded Handheld Home screen or Android
App Drawer;
2) Manually via Intermec Settings > Communications > WWAN
Radio > Carrier Selection (N/A for Android);
3) Automatically using programming APIs provided by
Intermec and integrated by the app developer;
4) Automatically based on signal strength or location
information. (Note that these methods require the WWAN
Toolkit, available for license from Intermec for WEH only.)
Q: Why is the Flexible Network radio not available for EMEA?
A: We do not support CDMA carriers outside of North America
and therefore customers would not benefit from a Flexible
Network radio that allows switching between UMTS and CDMA
networks. Multi-national customers desiring a common
platform worldwide are a special consideration; please contact
the Product Management team to discuss such opportunities.
Q: Can I get cellular voice with the Flexible Network radio?
A: Yes. The CN51 Flexible Network radio supports both voice and
data unlike the Qualcomm Gobi 3000 radio technology which is
a data only radio technology and does not support cellular
voice. Note: There are also 3rd party Push-to-Talk and VoIP
applications available that will allow voice communications over
the data network.
Q: What is the difference between UMTS in the Flexible Network
radio option (available for NA, LATAM, and ANZ) and the
UMTS radio option (available Worldwide except NA, LATAM,
and ANZ)?
A: The frequency bands supported by these configurations are
slightly different: Flexible Network radio option supports
UMTS 800, 850, 900, 1900, and 2100 MHz bands, and GSM/
GPRS/EDGE 850, 900, 1800, and 1900 MHz bands; UMTS radio
option supports UMTS 900 and 2100 MHz bands, and GSM/
GPRS/EDGE 900 and 1800 MHz bands.
Q: Where is the SIM card slot located?
A: The SIM card slot is located behind a door inside the battery well.
Q: How is the SIM card installed?
A: The SIM is held in a silver metal
bracket that also houses the microSD
card. To install the SIM, the top of the
bracket must be moved to the left,
allowing the top to rotate upward.
The SIM is inserted, contacts facing
down, in the top portion of the
bracket, which is then rotated
downward and secured by sliding
to the right.
Q: What is the purpose of a SIM card and when do I need one?
A: The Subscriber Identity Module (SIM) is used by UMTS phones
to provide information about the user, including phone number,
contacts stored on the card, etc. SIMs are not used with CDMA
phone systems.
Q: Does the GPS require the WWAN radio to operate?
A: Yes, the GPS requires a WAN radio option (either the Flexible
Network radio or the UMTS radio) and the WAN radio must be
enabled (powered on), but a data plan with a wireless network
carrier is not required to use GPS. However, assistance data
used to reduce Time to First Fix (TTFF) could be sent via the
WAN network with a valid data plan. Without assistance data,
the GPS may experience slower TTFFs.
