NOTE:
3650 MHz is for APs and Fixed Remote stations only.
• Use connectionware—The use of connectionware in the mobile lap-
tops is highly recommended for better operation of a mobile data
system. GE MDS provides connectionware from one of the vendors
in this market. Contact your factory representative for details.
• Plan your network coverage—Deploy Access Points so that they
provide overlapping coverage with each other. Access Points must
use the same Network Name to enable roaming service.
• Set the RSSI Threshold to -70 dBm—This level is typically used for
mobile systems with good performance. Make sure there is overlap-
ping coverage of more than one AP to provide continuous coverage.
• At every AP Radio, review the following settings when providing
service to mobile remotes:
• TDD Sync —Set to GPS Required .
• Pattern Offset —Each AP should be different. Cell planning is
required if there are overlaps.
• Hop Pattern —Set the same on all APs.
• Compression [ disabled ]—Disable radio compression. Data com-
pression is best performed by the connectionware running on
the mobile laptop PC. Gains in efficiency are made because
connectionware compresses data at a higher stack level, and it
aggregates multiple data frames and streams into a single
packet. Compression at the radio level, although highly effi-
cient, works only at the individual packet level.
