AIR DIGITAL WIRELESS TRIPLE PLAY NETWORK
AIR DIGITAL WIRELESS TRIPLE PLAY NETWORK
Air is a unique integrated wireless Triple play point to multipoint system solution on the telecommunication market, providing microwave
radio access to all the residential and business users in a radius of over 15km from every base station. An operator (CATV, ISP, incumbent,
others) is able to provide all services, users are looking for today – digital TV broadcast (more than 100 digital TV programs in DVD or HD
quality at the same time), Broadband Internet, VoIP telephony, FAX services, Pay per View, Video on Demand, Telemetry, etc.
Standards used in the Air system are the same as in bidirectional digital cable TV networks – DVB-T and HDTV for TV broadcast and
DOCSIS/EuroDOCSIS for IP transfer (including VoIP). The downstream distributes TV and RA programs and IP traffic as in standard
CATV network (the broadcast is similar to Satellite broadcast), upstream consist of IP traffic only (including VoIP) in the direction from
the end user to the Main station. The same system can be used in a standard coaxial, analog or digital cable TV network or in a combined
network (wireless and cable), providing both – TV and IP access over wireless and coaxial cable infrastructure. The Air system is suitable to
expand the network and service portfolio of ISPs, mobile operators, incumbents.
By implementing the AIR system, an operator is able to provide the most advanced triple play services to his customer base, by having low
customer acquisition cost, Fast Deployment and Immediate start of Revenues resulting in Return on Investment typically
in 18 to 30 month.

AIR DVB-T
The DVB-T modulator provides
Forward Error Correction, modulates the
digital MPEG2 signal in QPSK, QAM 16 or
QAM 64, according to the DVB-T standard
in the UHF frequency band; C2 to C69
(471 to 862 MHz). The channel bandwidth
is 8 MHz (for 4 to maximum 9 video/audio
signals).The modulator has a possibility of
4 independent outputs; each of them can
use a separate frequency – possibility of
distributing the same TV and RA programs
in DVB-T format to 4 different operators.
G system
AIR CODIN
The AIR CODING system
(SCRAMBLER) provides the operator with
the possibility of preventing unauthorized
access to the air distribution services
and provides better data transmission
protection. AIR coding system offers
flexibility of providing individual TV and RA
program scheme to each separate user
in the system. The AIR coding system is
connected via the AIR IP inserter to the RF
transport stream.

transport
The Wireless internet transport
system enables the seamless transport
and frequency conversion from standard
DOCSIS/EuroDOCSIS CMTS to the
base station and then to the end user, and
also enables the seamless transport and
conversion of frequency from the end user
to the base station and then to the standard
DOCSIS/EuroDOCSIS CMTS.

AIR Multip
The MUX digital multiplex equipment
multiplexes 4 to maximum 9 (depending on
the compression rate) TV and RA programs
in digital MPEG2 format, received through
an ASI or SPI interface. The MUX adds
to ASI or SPI stream an additional data
channel received from the IP DVB inserter
(channel coding information).

The Network Management Server
allows the operator to do Remote
Supervision and Control of all the Network
Elements. The server generates Alarms
in case of failures and errors. The network
management server also allows Remote
configuration and Administration. These
features are all protected by strong
encryption.

The DVB Control server generates
a code for each TV and RA channel, and
checks the database on the user database
server, where it is specified to which TV
and RA programs a user has access to.
The control server is connected to the Air
CODING system which generates the code
to an ASI interface.
B inserter
AIR IP DV
AIR IP inserter inserts a data stream
of IP into the RF transport stream and
acts like a translator between IP and RF
traffic. In the IP data stream are include
a code from the AIR coding system,
EPG (electronic program guide), other
information.

data base and allows the end user real-time
access from a web browser in order to get
certain information or access to certain
services (Pay per View, Video on Demand,
etc.) The server also runs the user
database which allows user manipulation
to the operator (time limited use of certain
channel, Video on Demand, billing etc.).

AIR Satellg T V and RA
and analo tor (receiver)
demodula
Source of TV and RA programs in the AIR
system are digital and/or analog satellite/
terrestrial/cable TV and RA programs,
received through satellite and terrestrial
antennas or through cable.
The satellite demodulator converts
the received signal on the 1. Interfrequency
to ASI output (in the case of digital
receiver) or to analog signal (audio and
video) in the case of analog receiver. In
the case of an analog receiver, video and
audio are then digitalized through MPEG2
encoders (ASI output provides the MPEG2
format directly). The MPEG 2 encoder can
define a higher compression rate if needed.
Signals received in digital format can not be
additionally compressed.
Microwave radio connection
for remote base stations
P2P link
The Point to Point radio link
provides an exclusive bidirectional wireless
connection between the main and base
station (if they are in different locations)
and feeds the multipoint antennas at the
remote base stations. The Point to Point
connection transports the same frequency
bandwidth, produced at the Main and
base station. The microwave connection
transports the whole transmitted and
received uncompressed frequency.
Base station
Base station
The multipoint antenna enables bidirectional communication between the main
station and end-users.
DOWNSTREAM
The multipoint transmitter receives the signal from the AIR main station on the
interfrequency. The signal is then converted to high TX frequency (Downstream
transmission frequency) filtered and amplified. The bandwidth of the frequency is the
same as the bandwidth received from main station. The Downstream transmission
frequency is then transmitted through the antenna with a typical gain of 10 dB
(depending on the frequency and antenna system – Omni directional, sectorized).
UPSTREAM
The multipoint receiver receives and down converts the high frequency signal
(upstream receiving frequency), filters and amplifies it and then sends it to the AIR
Wireless internet transport system which is connected to a CMTS. If needed, the
signal can be also transmitted from the base station to the CMTS through coaxial cable
network, fiber optical backbone or microwave radio link.

User unit outdoor/indoor
The end user equipment includes an antenna with the AIR transceiver, which allows bidirectional communication
with the base station, the AIR settop box (Dolby digital sound) and a standard cable modem for IP traffic and
an optional IP or analog telephone(connected to SIP server interface).
REMARK : Multiple users can be connected to one AIR transceiver
User outdoor/indoor unit
User outdoor/indoor unit
Outdoor unit
DOWNSTREAM
The AIR transceiver receives the downstream transmission frequency which
transports TV and IP (data and voice) content through the dish antenna and
filters the signal before down converting it to a UHF signal. The UHF signal is
then transmitted through a coaxial cable to a splitter which splits the signal to a
cable modem (for IP traffic) and to the AIR receiver box (for TV and RA service).
(Multiple AIR settop boxes and modems can be connected to the same
outdoor unit)
UPSTREAM
The AIR transceiver receives a DOCSIS/EuroDOCSIS signal, containing upstream
IP content, from the cable modem, filters and amplifies it. The signal is then
converted to the upstream receiving frequency and transmitted with a typical RF
power of 10 dBm (with automatic gain control according to the CMTS instructions)
to the antenna and then transmitted through the antenna with a gain of 25 dB
(heavily depending on frequency and antenna size). Signal modulation is in
accordance with the DOCSIS/EuroDOCSIS standard, the RF power is controlled
by the CMTS. Maximum broadband bandwidth per user complies with the DOCSIS/
EuroDOCSIS standard. The unit is compatible with DOCSIS/EuroDOCSIS 1.0, 1.1,
2.0, 3.0 and future DOCSIS/EuroDOCSIS standards
REMARK: In case of TV and RA services only, AIR receiver (simpler version) can be
used.
Indoor units
Cable modem
The AIR settop box converts the
UHF signal on the transport stream SPI,
descrambles the signal and then decodes
the MPEG2 format to an analog audio/video
signal compatible with a standard TV set.
The system uses a standard
DOCSIS/EuroDOCSIS cable modem
(interfaces and number of them vary
on used model and type of modem).
alog phone

The system is fully compatible with any
IP phone with an Ethernet interface
or with any analog phone and also
supports Fax applications.
