3. Current situation
 Current situation Customers are demanding more
and more data applications to be delivered on the
go. However, the operator is using scarce
expensive licensed spectrum that is
overburdened with delivering core voice.
 The operator is facing a choice of acquiring more
licensed spectrum or losing customers due to
demand for advanced services.

4. Cognitive radio
 Cognitive radio : Cognitive radio (CR) is a form of
wireless communication in which a transceiver
can intelligently detect which communication
channels are in use and which are not, and
instantly move into vacant channels while
avoiding occupied ones.
 This optimizes the use of available radio-
frequency (RF) spectrum while minimizing
interference to other users.

5. What is XG ?
 xG Technology, Inc. is developer of technology
for wireless communications.
 The company developed cognitive radio technology
for mobile services using licensed or unlicensed radio
spectrum.xG’s initial product is xMax, a carrier-class
cognitive radio network. xMax is a
mobile VoIP and broadband data system with an end-
to-end Internet Protocol (IP) system architecture.
 The company deployed a 30-square-mile (78 km2)
xMax network in the Fort Lauderdale, Florida area

6. xMAX technology
 xMAX technology : xMax’s standards-based IP
architecture minimizes network deployment.
 Using field-proven cognitive radio technology,
xMax enables the delivery of mobile services in
both licensed and unlicensed bands.

7. xMAX cellular network

8. xMAX cellular architecture
 . The following are the major components of the
system:
 xMod
 xAp
 xMSC
 x Monitor/x Drive

9. Xmod
 Xmod : The xMod is a small battery that bridges
the COTS end user device to the wideband
transport layer of the xMax system.
 Devices connected via secure Wi-Fi links.
 The xMod can deliver up to 3.5Mbps to the
connected end user device(s).

10. Xap
 Xap : The xAP acts as a compact, high-
performance base station and wirelessly
connects to the xMod using the xMax cognitive
networking waveform.
 Each xAP can deliver up to 14 Mbps to its
associated xMods.
 xAPs may be deployed individually or in clusters
of up to 9 xAPs to increase total throughput.

11. Xmsc
 X msc: The xMSC acts as both a base station
controller and aggregation point for the
connected xAPs.
 The xMSC is typically connected to the worldwide
Internet.

12. x Monitor/x Drive
xMonitor is a component of the xMax-xMSC that
monitors the status and health of xMax network
elements. It provides end-to-end IP network
management and monitoring services, services,
allowing support personnel to quickly gather information
about xMax networks.
xDrive is a drive mapping utility designed to gather,
display, and log performance statistics from xMod and
xVM mobile hotspot devices. It allows field technicians
to map the coverage of a deployment of xMax access
points (downlink), as well as providing user-to-network
(uplink) statistics.

13. Working of x-Max Technology
 WORKING OF XMAX TECHNOLOGY-
 ADVANCED COGNITIVE SENSING.
 MITIGATING INTERFERENCE.
 ADVANCED ANTENNA.

14. Advanced Cognitive Sensing
 Conventional, or “dumb” radios, have been designed
with the assumption that they were operating in a
spectrum band that was free of interference. As a
result, there was no requirement to endow these
radios with the ability to dynamically change
parameters, channels or spectrum bands in response
to interference.
 xMax cognitive radios can identify potential
impairments to communications quality, like
interference, path loss, shadowing and multipath
fading. They can then adjust their transmitting
parameters, such as power output, frequency, and
modulation to ensure an optimized communications
experience for users.

15. Mitigating Interference
 interference works against reliable and efficient
wireless communications. Interference can
negatively impact performance and coverage,
and is the chief limiting factor in high-capacity
mobile systems. interference is responsible in
many cases for dropped calls, slow download
speeds and shortened battery life.
 xMax leverages proprietary xG developed
technology to implement two key approaches to
dealing with interference.
 The first is Dynamic Spectrum Access (DSA) and
 Second one is by using 2x4 MIMO antenna
configurations.

16. Dynamic Spectrum Access (DSA)
 xMax uses its real time sensing of interference
on a channel to instantly change channels when
better frequencies are detected. However, xMax
goes beyond simple DSA by incorporating
sophisticated interference mitigation (IM) software
that enables xMax to reliably operate on
interference laden channels that other radio
systems could not operate on. When xG’s
interference mitigation technology is added to its
DSA capabilities, xMax can greatly increase the
capacity of both new and existing spectrum
assets.

17. 2x4 MIMO antenna configurations.
 The xMax radios employ new and powerful parallel
processing digital signal processers and computer
processing units (DSP/CPU) that support speeds up
to 50 Giga OPS (billion operations per second) for
signal processing. This capable processor, combined
with 2x4 MIMO antenna configurations, enables the
xMax system to use patent-pending spatial
processing software to remove unwanted interference
from the target xMax signals. Each xMax cognitive
radio can simultaneously mitigate up to 24 mobile
sources of interference or jamming. By using xMax’s
multi antenna technology to separate unwanted
interference from desired xMax signals, xG is able to
offer robust and reliable links in conditions that would
cause other radio systems to completely fail

 In Rural deployments.
 In Military applications.
 In Location-based services.

20. Advantages
 Quality of service (QoS) to support long ranges
mobile VoIP.
 Header compression.
 Soft hand- off mechanism.
 No spectrum license costs.

21. Future Scope
 The XMAX™ technology can provide fixed,
nomadic, portable solution and with OFDMA at
the heart of the technology, it can also deliver
mobile wireless broadband connectivity across
vast open and congested areas, over many
kilometres.

 Broad coverage is possible.
 service provided to more number of customers
