1. OVERVIEW

JRC FWA SYSTEM 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 to ensure 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.

1.3. System Configuration

One Access Point (AP) has the capacity of linking with up to 239 subscriber terminals to
configure a point-to-multipoint (P-MP) communications system. An omni-directional
antenna (with horizontal directivity of 360°) mainly for a residential area of detached houses
and a Sectoral-Horn-type antenna (90° × 10° directivity) mainly for multi-tenant building are
available.

Wireless Terminal (WT), including the antenna and all the electric circuits, is designed
compactly (19cm x 19cm x 7cm) and can easily be installed at any outside places of
residential houses. WT is connected to a PC through one LAN cable and supplied with
power through a tiny power supply adapter.



1-3

Second layer isolation of subscriber traffic is provided by 802.1Q VLAN-tag. Broadband
Access Server (BAS) terminates access layer functions and relay user traffic to IP backbone
network.
The Operation System (OpS) allowing the installation and registration of subscriber
terminals and the supervision of its operational status is optionally available.

3.1. AP-RFU

3.1.1. Overview

The AP-RFU consists of three blocks: Antenna section, RF section and IF section.

3.1.2. Antenna section

The omni-directional antenna (with horizontal directivity of 360°) and the Sectoral-Horn-type antenna
( 90° × 10° directivity) look the same.

3.1.3. 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.

3.1.4. 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 controls 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 functionality 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.

3.2. AP-IFU

3.2.1. Overview

AP-IFU consists of three blocks: IF section, digital section and interface section.

3.2.2. 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 functionalities 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).
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.

4.1.8.2. Switches

Figure 4-3 Switches on the WT Adapter

(a) [TEST SW] switch
This is the switch to check for any disconnection on the Ethernet cable connecting the

WT and WT adapter.
The connection of the ETHER signal line (4) in the Ethernet cable (8) can be confirmed.

If you turn on this switch, the Ethernet signal is looped back to the WT and not output to

the PC port.

How to check for a disconnection:

• connected to cable between WT and WT adapter, and turns on the power supply with
the AC adapter.

• Unplug the cable from the PC port of the WT adapter.

• Make sure that the ETHER LED lights.

• Hold down the TEST SW switch.

• (The Ethernet signal from the WT is looped backed to the WT via the WT adapter.)

• The connection is normal if the ETHER LED lights green.

• The four Ethernet signal lines have a disconnection or wrong wiring if the ETHER LED
remains extinguished.

・The TEST SW cannot identify a wrong connection for the

straight/cross cable. When

connecting a connector, make the correct connection for the straight or cross cable.

If you turn on this switch by mistake, the Ethernet signal is looped back to the WT and not

output to the PC port.
