For more information, refer to the LNA Bypass section below to assist in interpreting the
results.
When streaming data, Wi-Fi interference is at its worst. Wi-Fi interference is easiest to track
down when it is streaming. When Wi-Fi is not transmitting data, WAPs continually transmit a
beacon at full power at a typical rate of 10 per second. Beacons show up in the peak
energy levels.

LNA Bypass

The gateway has an RF receiver amplifier (Low Noise Amplifier) with a gain in the range of
11.5 to 15 dBm. The LNA boosts received signals that extend the distance from which it
can hear devices. However, in the presence of a strong interferer, such as a nearby WAP,
the extra gain reduces the gateway’s ability to reject interference. As interference power
increases, the loss of rejection starts in adjacent channels and then spreads to all channels.
For the CEN-GWEXER and CEN-RFGW-EX, as the peak level reported by the Energy Scan
command is in the range from -30 to -34/ dBm, the potential for problems increases. Keep
in mind that lower negative numbers represent stronger signals. In and of itself these levels
are not a problem. If the interference comes from a WAP, problems would be evident only
when Wi-Fi is transmitting more continuously, such as occurs during file transfers or
streaming. During streaming, the average value would be much closer to the peak.
The loss of rejection can be mitigated by bypassing the LNA. Newer versions of gateway
firmware have the LNA bypassed by default. Check the setting to be certain.
Using Crestron Toolbox open a console to the gateway and issue the following commands:
>LNABYPASS ? (Displays command usage)
>LNABYPASS (Displays the current setting)
>LNABYPASS ON (Bypasses LNA)

Adding a Wi-Fi Filter

There are installations that use the CEN-GWEXER and either a CEN-WAP-ABG or a
CEN-WAP-1500. In some of these installations, sustained Wi-Fi traffic has disrupted the
CEN-GWEXER traffic, causing its network to fail. These WAP devices transmit a very high
power level that can interfere with all Zigbee channels, especially when the WAP device is
somewhat close to the CEN-GWEXER. While it is recommended to always place gateways
and WAPs as far apart as possible, it is not always possible to locate them 15 feet or more
apart.
The answer to this problem is to add a filter. The filter is installed between the gateway and
the antenna, which reduces all signals outside the desired channel. The filter chosen is set
to allow signals on Zigbee channels 25 and 26 to pass. All other signals are attenuated.

Frequently Asked Questions

Can't find the answer to your question in the manual? You may find the answer to your question in the FAQs about the Crestron CENI-GWEXER-PWE below.

What is the weight of the Crestron CENI-GWEXER-PWE?

The Crestron CENI-GWEXER-PWE has a weight of 253 g.

What is the difference between a router and a modem?

A modem provides the internet connection via the internet provider. A router then distributes the Internet signal to the devices connected to the router.

What does the download speed on the internet depend on?

The download speed on the internet depends on the type of connection you have. If you have a 25 Mb/s connection this means that theoretically you should be able to download 25 MB per second.

Is WIFI radiation harmful?

WIFI is a radio frequency signal in the form of non-ionising radiation. This radiation cannot damage cells and tissues and is therefore not harmful to human health.

Is the manual of the Crestron CENI-GWEXER-PWE available in English?

Yes, the manual of the Crestron CENI-GWEXER-PWE is available in English .
