iPoll PTMP protocol

One of the most effective wirelessOne of the most effective wirelesstransmission protocols in the market!transmission protocols in the market!

Ideal for real timedata applications

Scalable systemwith support formultiple clients

No distancelimitation

Decreasedlatency

Proprietary iPoll™ wireless protocol improves the wireless medium utilization against the standard DCF (Distributed Coordination Function) method. It eliminates mediated access by polling every subscriber sequentially. The data y p g y q ytransmission arbitration is accomplished by the access point. The AP sends a data and a poll frame to a station and receives data from the polled station before starting to poll other stations. Each station starts sending data once a poll frame is received. Proprietary iPoll™ protocol allows to obtain


maximum bandwidth with the lowest possible latency.

Without and with iPoll

iPoll PTMP protocol

An example below. shows real-time (video) data transmission to two different clients. The upper client is using proprietary iPoll™ point to multi using proprietary iPoll point to multi point protocol which is extremely efficient for the applications requiring low latency, better PPS (packet per second rate) and higher capacity per subscriber.

Vid ill li ti APC i d blVideo surveillance application – APC series as good as cable

Deliberant APC series (MiMo) equipment was tested using digital video recording with splitter to simulate 16 cameras. 3 different tests were carried out using different compressions with a different number of cameras:

• 12 cameras with D1 compression (30 fps)• 16 cameras with D1 compression (30 fps)• 16 cameras with D1 compression (30 fps)• 16 cameras with CIF compression (15 fps)

The performance results were compared to a data transmission using cable in the graphs below.

It is called Mean Opinion Score (MOS). MOS gives a numerical indication of the perceived quality of the media received after being transmitted and eventually

Smart auto-channel

Automatic transmit power control and DFS 3 is supported on all Deliberant APC series equipment with a firmware v5.76 and above.

Smart auto-channel

Smart auto-channel detection system makes Deliberant APC series equipment makes Deliberant APC series equipment extremely noise immune. The base station changes the whole network operating frequency during the startup, after radar detection or every 5 minutes if the are no stations connected to the access point at the time of pre-scan. Service providers can p pspecify the channel hopping list for their base station operation to use only specific channels available in the area. Smart auto channel will also sense the radar signals and shift the frequencies accordingly and this feature is also compliant with ETSI EN


Smart auto-channel automatically selects the less occupied channel for operation during the startup of base station.

Spectrumanalyzer

A spectrum analyzer is a device used to examine the spectral composition of some electrical, acoustic, or optical waveform. It may also measure the power pspectrum.

Nowadays, as the unlicensed band is becoming really crowded it is essential to scan the spectrum before d l i i l deploying any wireless equipment to make sure you will be getting the best performance.

Normally spectrum analyzer is a very expensive device and Deliberant has integrated

It is a real-time spectrum scanning tool, which provides a graphical signal representation and displays maximum, average and current signal (noise) level.


Deliberant has integrated similar functionality for FREE in the APC product line.
