Secure Wireless Networks that Provide Connections
at ANY Distance

2.
Private Wireless Networks
Traditionally, private wireless networks have been limited in
distance as to how far a remote transmitter can link either to a
master or repeater site.
The wireless network design requires all remote locations to have a
communication path back to a central location for data collection,
control, or monitoring.

3.
Traditional Limitations
Private wireless networks traditionally reach distant locations by
either increasing the output power of the radio or changing to a
lower frequency band.
The ability to increase output power or select a lower frequency
band is not available, as radio frequency (RF) data rates have
increased through the use of spread spectrum technology in
operating frequencies above 900 MHz.

4.
Traditional Limitations
These spread spectrum radios are very limited in output power
(generally less than 1 Watt) and only operate in frequencies above
900 MHz.
The associated operating frequencies above 900 MHz have
increased bandwidth availability leading to the high throughput. But
the limitations on the power output and their natural signal losses
due to vegetation and terrain mean that more infrastructure (i.e.
repeaters or higher towers) was required to reach remote locations.

5.
New Connections
ESTeem wireless networks have always been able to use any remote site
as a repeater.
We have been able to overcome many of the distance limitations by
using this Mesh repeating feature, but now that we have incorporated
cellular technology in our product line, we can reach these outlying areas
without having to link to a single wireless network.

6.
New Connections
For example, in many communication networks there are one or two
remote locations that fall outside the coverage area of a single base
radio.
Traditionally, these remote locations would then require adding one or
more repeaters, but now these remote sites can be incorporated into the
wireless network by simply installing a cellular radio such as the Edge
Access+.
A cellular radio can also be used to bridge between smaller private
wireless networks for maximum network flexibility.

7.
A Giant Leap Forward
Adding the Edge Access+ to our product offering has given our network
design capability a giant leap forward.
We can now create hybrid networks of multiple frequency bands and
wireless technologies to design the most creative private wireless
networks to meet ANY distance or application.

The ESTeem Advantage
For over 30 years, we’ve designed, engineered and manufactured industrial
wireless radios and modems - all in the US and all specifically focused on solving
our customers’ most difficult networking challenges, no matter what the frequency.
Through all those years, we’ve stuck to the philosophy that applications will not
bend to fit the hardware. The solution must fit the application, and we work with
our customers to ensure they get the right wireless solution to fit their needs.
To that end, all of our models come with full compatibility
baked in (195E/Horizon, 192/195 Narrowband), and we
write our software/OS specifically for the components used
for optimum efficiency and performance.
