This document covers all the radio, electrical and mechanical aspects of the
QUARTZ-GOLD-5G NR router. For programming and use of this product in a
computer network, please refer to the QUARTZ-GOLD-5G Software Manual.
This manual is intended to guide on how to connect the QUARTZ-GOLD-5G router
into a computer network so that it may be used as the gateway router either to a
WAN or the 5G NR cellular network, with the option of automatic fallback between
the two. For complete network conguration, it is necessary to set up the network
using the built-in web server for which reference to the companion software manual is
required.

The QUARTZ-GOLD-5G uses a Mediatek 880 MHz MIPS dual-core processor with
256 Mb ash and 2 Gb of DDR3 RAM. This processor runs a Linux based Operating
System which controls the web interface and routing functionality of the router. VPN
throughput is enhanced with a hardware IPSec crypto engine onboard the MIPS
processor.
The cellular capabilities of the QUARTZ-GOLD-5G are powered by the Quectel
RM520N-GL Module. This uses the Qualcomm Snapdragon X55 5G Modem which is
manufactured on a leading edge 7 nm semiconductor fabrication process.
As well as offering two Gigabit Ethernet interfaces, the QUARTZ-GOLD-5G also offers
an RS232 interface that may be used to connect serial ports on products such as
door access controllers and alarm panels to the Internet.
Wi-Fi 5 (802.11ac) comes as an option, with backward compatibility modes allowing
both 2.4 GHz and 5 GHz frequency operation to be supported.
Three modes of networking operation are possible:
1. 5G NR cellular router where the WAN connection of the router is the 5G NR
cellular interface. In this mode all Ethernet interfaces are for LAN use. Internet
connectivity comes from the internal cellular interface.
2. WAN router where one of the Ethernet ports of the router is used as the WAN
connection. The WAN port in this case would normally be connected to a cable
or ADSL modem to obtain Internet connectivity.
3. Backup router which combines the two above modes. The router can switch
between the cellular and WAN connections automatically to maintain Internet
connectivity should one path fail. The preferred route can be set to cellular or
WAN.

1. All measurements were done with 12V input.
2. Current consumption gures given in the table above are average current
measurements over 15 minutes and are not estimates. When the cellular
connection is active there will be short current pulses signicantly greater than
the average values provided. It is important that the 12V supply used to power
the router can deliver at least 2.0 A to prevent network disconnections caused by
these current pulses.
3. All current measurements are started after the router has been rebooted with
the test conguration and time allowed for the router to connect onto the cellular
network, settle on a cell, and get an Internet connection.
4. Sky News may be accessed at https://news.sky.com/watch-live. The news video
is an embedded YouTube frame. It should be possible to access internationally (if
not, try using a VPN). When viewed, quality is set to 1080p and viewed full screen.
5. Speedtests were conducted using the web site https://www.speedtest.net. Current
measurement is from clicking ‘go’ on the website to the speed measurement
results being displayed. Speeds achieved are limited to the capability of the
cellular cell connected to, and in the case of measurements done over Wi-Fi, also
the capabilities of the Wi-Fi connection.
6. The power consumption when used with UMTS, LTE and 5G NR networks is
broadly similar for like connection speeds. Cellular power consumption will be
affected more strongly by proximity to the serving cell (closer to the cell = less
transmitting power required), weather (heavy rain/snow = more signal attenuation
and greater transmit power) and operating band (lower frequencies are generally
lower power). Measurements in the table above were conducted with the CSQ
reported on the status page typically 15 with the connection on band 3 (1800
MHz). A 5G SA connection on band n78 (3500 MHz) using 2x2 MIMO is the
highest power consumption and can be expected to elevate the measured values
by as much as 350 mA at full data rate.

QUARTZ-GOLD-5G
Hardware Manual
Radio Characteristics
The QUARTZ-GOLD-5G supports Wi-Fi using a MediaTek radio that is IEEE802.11n/
ac compliant. This means that it will work with other Wi-Fi adapters supporting IEEE
802.11a/b/g/n/ac. The 2.4 GHz and 5 GHz wireless bands may be independently
congured.
2.4 GHz bands may be set to 20 or 40 MHz channel width.
5 GHz bands may be set to 20, 40 or 80 MHz channel width.
A channel congured for 2.4 GHz operation may be used as 802.11b only, 802.11g
only, 802.11b/g mixed and 802.11n only, as well as the default 802.11b/g/n mixed
mode (congured by software).
A channel congured for 5 GHz operation can be used as 802.11a only and 802.11n
only, as well as the default 802.11ac mixed mode (congured by software).
Wi-Fi Characteristics
Table 14. 2.4 GHz Wi-Fi band support
IMPORTANT: While the QUARTZ-GOLD-5G can support all 2.4 GHz Wi-Fi channels, the regional settings in the Wi-Fi
conguration page will limit the available channels to meet the regulatory requirements of the country in which it is being used.
Siretta always recommends that the region setting be correctly congured for the country in which the router is being used.
