Installation Considerations

The Motorola Cellular Gateway NC800 is designed to let you access your network using a wireless connection
from virtually anywhere. Please keep in mind that the number, thickness and location of walls, ceilings or other
objects that the wireless signals must pass through may limit the range.
To maximize the Motorola Cellular Gateway NC800's wireless range:
1. Keep the number of walls and ceilings between the Motorola Cellular Gateway NC800 and your
receiving device to a minimum – each wall or ceiling can reduce your Motorola Cellular Gateway
NC800's range from 1-30 meters.
2. Building materials make a difference – metal or aluminum objects may have a negative effect on range.
Try to position the Motorola Cellular Gateway NC800 and computers with wireless adapters (clients) so
that the signal passes through thin walls or open doorways and not other materials.
3. Use the signal strength indicator present in most wireless adapters' software to experiment with the
signal strength in various positions in the building where you are going to use the Motorola Cellular
Gateway NC800.
4. Keep the Motorola Cellular Gateway NC800 away (at least 1-2 meters) from electrical devices that
generate Radio Frequency (RF) noise.
For the average home or office, signal range should not be an issue. If you experience low or no signal strength
in areas of your home or office that you wish to access, consider positioning the wireless Motorola Cellular
Gateway NC800 in a location directly between the computers with wireless adapters. Additional wireless
gateways can be connected to provide better coverage in rooms or offices where the signal does not appear as
strong as desired.
LAN capacity:
The theoretical upper limit of the number of devices connected to a class C Ethernet and/or wireless LAN is
253. This upper limit is due to the IP address structure of a class C network. (Please refer to the Glossary for
more details on the IP address structure.) However, several factors should be kept in mind when designing
your network:
1. The devices on the network share the available bandwidth on the WAN link if simultaneous WAN
access is required.
2. As many as 32 wireless devices can be attached to the WLAN. However, it must be kept in mind that
each wireless client of the Motorola Cellular Gateway NC800 shares the available bandwidth on the
WLAN with all the other wireless clients on the WLAN.
3. The bandwidth on the Ethernet LAN would be shared if a device such as a hub is connected to the
Motorola Cellular Gateway NC800 to create a wired LAN with multiple devices.
