Data Throughput vs. Port Speed
As previously discussed in Channel Assignments &
Bandwidth, configuring a radio module’s ports involves
setting data throughput and port speed.
The data throughput setting is the over-the-air pass-
through capability, and must correspond with the
capacity needed for the chosen service of that port.
The port speed applies to the rate at which data is
sent and received across the port to the attached
device.
Port speed can be configured at a higher rate than the
Channel throughput. However, if average throughput
exceeds Channel throughput capacity, data will be lost.
Data Interception Protection
The Safari Network incorporates protection against
intentional or unintentional interception, interference, or
unauthorized access
data on the network. The SR-7100
modulation uses a proprietary patented version of direct
sequence spread spectrum. By spreading carriers at low
energy across a wide bandwidth, it makes any type of
radio interception, or interference difficult to implement.
Each radio module is manufactured with a unique
hardware address. To enter any Safari Network every
unit’s address must be pre-approved by the network
administrator. Each radio module must be specifically
authorized by the network administrator to access any
offered service.
The network administrator must set the radio module to a
unique programmed spreading code common to each
network. To communicate on the network, Safari Network
radio modules must utilize a unique pre-pended training
pattern set by the network administrator (called a Unique
Word).
