1. OVERVIEW
JUL-6226 is a broadband wireless point-to-multipoint communication system operating at
24-26 GHz that provides high-speed IP access. The 80Mbps/40Mbps wireless transmission
rate is available on one frequency channel having the RF bandwidth of 26MHz. The wireless
transmission rate depends upon the selected modulation system (16QAM/QPSK), which is
controlled for each subscriber terminal to be adapted with the radio propagation path
environment such as the distance from the access point and rainfall conditions. The maximum
throughput (average data transmission rate of an Ethernet frame) received and transmitted by an
access point is 46Mbps.
The data transmissions in radio channel are encrypted by different keys for each subscriber
terminal encrypt so that ensuring sufficient security. The system can deal with the subscribers
fairly in assigning the bandwidth, regardless of the distances of subscriber terminals from the
base station.

3. AP
3.1 AP-RFU
3.1.1 Overview
The AP-RFU consists of three blocks: Antenna section, RF section and IF section.
• Antenna section
The omni-directional antenna (with horizontal directivity of 360°) and the horn-type antenna ( 90° × 10°
directivity) give same shapes of AP-RFU.
• RF section
In the RF section, the transmission IF signals are up-converted into 24-26 GHz-band RF signals using the
local signal, which is generated by multiplying the 2.4 GHz synthesized oscillator. The next-stage BPF
eliminates unwanted sideband components. The up-converted 24-26 GHz-band RF signals are amplified up to
the desired level then fed to the antenna via the TDD-Switch and the Waveguide Filter.
The received 24-26 GHz-band RF signals by the antenna are fed in to the LNA via the Waveguide Filter and
the TDD-Switch. The output signals of the LNA are down-converted into IF signals using the local signal,
which is generated by multiplying the 2.4 GHz synthesized oscillator. The BPF is employed to eliminate the
image components (interference).
The TDD Switch selects the transmitting or receiving function. Detection of the transmiting burst at the IF
section turns the switch to the transmiting side.
• IF section
In the receiving IF section, the output level to the AP-IFU is adjusted by the automatic gain control (AGC)
function, so that the input level of the AP-IFU does not saturate for the reception of the WT signal which
gives highest receiving level. The SAW filter eliminates the adjacent channel interference.
In the transmitting IF section, the detection of the transmiting burst signal control the TDD-Switch in the RF
section to turn it to the transmiting side. The SAW filter provides the signal delay for the period of the burst
detection and the TDD-Switch turning time, as well as the elimination of the non-desired signal component.
The IF section also has the compensation functionarity for cable losses between the AP-RFU and AP-IFU.
The CPU in the IF section performs the AGC, the cable loss compensation , and the monitoring and control
functionalities.

3.1.2 Operations and Indications
The AP-RFU does not have any operation or indication panels.
3.2 AP-IFU
3.2.1 Overview
AP-IFU consists of three blocks: IF section, digital section and interface section.
• IF section
The transmission IF section performs quadrature modulation of 427.5MHz IF frequency according to the
transmission output from the digital modem installed in the WT-ASIC.
In the receiving IF section, the received burst signal level is adjusted by the automatic gain control (AGC)
function of the digital modem. The quadrature demodulator downconverts the received IF signal into the
baseband signal.
The digital section consists of a digital modem, TDD/TDMA framer, wireless MAC processor, and system
controller. These functionarities are equipped in the WT-ASIC.
The digital modem performs modulation and demodulation of transmitting and receiving burst signals.
The interface section has an interface between the AP and the upper unit (100BASE-TX). It provides a

The digital section consists of the wireless MAC processor, TDD/TDMA controller, modem and system
controller. The wireless MAC processor converts between the Ethernet frames that the interface section
handles and wireless MAC frames. It also schedules the dynamic slot assignment. The TDD/TDMA
controller performs scrambling, encryption, error correction and other processing. The system controller
performs operating parameter setting, state monitoring, control and testing for the modem, TDD/TDMA
processor, wireless MAC processor and network interface. It also sends and receives maintenance signals via
SNMP. It performs delay control, authentication and other procedures, operating parameter setting, state
monitoring, control and testing for the subordinate WTs over a DMF channel.
The transmission IF section in the IF section performs quadrature modulation for the transmission baseband
signals at 427.5MHz LOC frequency for upconversion to IF signals. It also controls the output level to the
desired level based on the control from the ASIC. The receive IF section equalizes the level of the reception
waves arriving in a wide level range using the automatic gain control (AGC) from the ASIC, and then
downconverts them into baseband signals.

4. WT
4.1 WT
4.1.1 Overview
The WT consists of the antenna section, RF section, IF section, digital section, interface section and
power supply.
• Antenna section
Uses a Triplate planar antennas to make the antenna compact and to provide a high gain.
• RF section
In the RF section, the transmission IF signals are up-converted into 24-26 GHz-band RF signals using
the local signal, which is generated by multiplying the 2.4 GHz synthesized oscillator. The next-stage
BPF eliminates unwanted sideband components. The up-converted 24-26 GHz-band RF signals are
amplified up to the desired level then fed to the antenna via the TDD-Switch and the Waveguide
Filter.
The received 24-26 GHz-band RF signals by the antenna are fed in to the LNA via the Waveguide
Filter and the TDD-Switch. The output signals of the LNA are down-converted into IF signals using
the local signal, which is generated by multiplying the 2.4 GHz synthesized oscillator. The BPF is
employed to eliminate the image components (interference).
The TDD Switch selects the transmitting or receiving function under the control of TDD/TDMA
framer installed in the WT-ASIC.
• IF section
The transmission IF section performs quadrature modulation of 427.5MHz IF frequency according to
the transmission output from the digital modem installed in the WT-ASIC. The SAW filter in the
next stage eliminates undesired out-of-band signals. The output level of the transmission IF secton
is adjusted by the automatic transmission gain control (ATPC) function of the digital modem.
.
In the receiving IF section, the SAW filter eliminates the adjacent channel interference. The
received burst signal level is adjusted by the automatic gain control (AGC) function of the digital
modem. The quadrature demodulator downconverts the received IF signal into the baseband signal.
• Digital section
The digital section consists of a digital modem, TDD/TDMA framer, wireless MAC processor, and
system controller. These functionarities are equipped in the WT-ASIC.
4-18
The digital modem performs modulation and demodulation of transmitting and receiving burst
signals.
The TDD/TDMA framer constructs and deconstructs radio burst frames. It alse performs scrambling,
encryption, and error correction functionarities.
The wireless MAC processor converts between the Ethernet frames and the wireless MAC frames in
the radio channel.
The system controller performs operating parameter setting, state monitoring, control and testing for
the entire unit. It also communicate with the AP processer via the DMF channel.
• Interface section
The interface section provides the physical interrfaces of Ethernet for user interface and serial
interface for the receiving level measurement terminal. It has a lightning surge protector to protect
the unit against external surges.
• Power supply
The power supply section generates various voltages used within the unit from +24V input power.
