1: Preface
If in a hospital or health care facility, do not use the router in areas where guidelines to
switch off mobiles phones are posted. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and hearing
aids can be affected by interference from wireless routers when placed close to the
device. People with pacemakers are advised to keep the wireless router away from the
pacemaker while it is on.
Do not operate your wireless router in the presence of flammable gases, fumes or
potentially explosive atmospheres. Wireless routers should not be used anywhere that
blasting operations are taking place.
Wireless routers operate using radio signals and cellular networks cannot be guaranteed
to connect in all possible conditions. Therefore, you should not rely solely on any wireless
device for life-critical communications.
1.5 Product disposal
The United Kingdom and Republic of Ireland are under an obligation to minimise the
disposal of Waste Electrical and Electronic Equipment (WEEE) in domestic waste and
encourage recycling, recovery and environmentally sound disposal. Virtual Access is
committed to promoting the reuse, recycling and recovery of WEEE by contributing to the
appropriate compliance schemes.
Our product packaging is marked with the crossed out wheeled bin symbol to indicate
that the product must not be disposed of in domestic waste but disposed of through an
approved WEEE take back scheme. For details of your local collection facilities, please
contact your local authority.

2: Introduction
2Introduction
The GW2020 Series can contain either a 3G or 4G wireless modem. The modem together
with a SIM card establishes a WAN connection to the Internet or private network.
3G is the third generation of mobile phone standards and technology. It is based on the
International Telecommunication Union (ITU) family of standards under the International
Mobile Telecommunications programme, IMT-2000.
3G and 4G technologies enable network operators to offer users a wider range of more
advanced services while achieving greater network capacity through improved spectral
efficiency. Services include wide-area wireless voice telephony, video calls, and
broadband wireless data, all in a mobile environment.
Data bearers are frame protocols that transport data streams. The GSM (3G) modem
supports GPRS, EDGE, HSDPA, HSUPA, UMTS and CSD. The 4G modem supports 4G
frequencies and fails over to 3G, GPRS and EDGE technologies.
2.1 4G LTE
4G LTE is the fourth generation of mobile communication technology standards. It is a
successor to 3G and provides greater bandwidth.
2.2 GPRS
GPRS (General Packet Radio Service) uses packet-switched technology to transmit small
bursts of data. The 3G or 4G modem on the GW2020 Series supports multi-slot class 6,
which allows a maximum data rate of 384Kbps class 3. The maximum data rate available
to the 3G or 4G modem depends on provisioning by the network operator.
2.3 HSPA+
High-Speed Packet Access + is an improvement on UMTS with achievable download
speeds of 21Mbps.
2.4 HSDPA
HSDPA (High-Speed Downlink Packet Access) uses circuit-switched technology to
transmit data at speeds of up to 7.2Mbps.
2.5 HSUPA
HSUPA (High-Speed Uplink Packet Access) is a 3G mobile protocol with uplink speeds of
5.76Mbps.
2.6 UMTS
UMTS (Universal Mobile Telecommunications System) is a third generation technology
providing higher transfer rates.
2.7 EDGE
EDGE uses the same frequencies as GPRS but offers better speeds. It is used when the
signal strength for 3G or 4G is not sufficient.

2: Introduction
2.8 CSD in EGSM900/GSM1800 MHz
CSD (Circuit-Switched Data) mode enables the 3G modem to transmit data over the
EGSM (Extended Global System for Mobile communications) frequency or the GSM
frequency. The modem behaves as a dual-band mobile phone behaves.

3: Getting started
3Getting started
3.1 Serial number
When you receive your GW2020 Series router package retain the outer packaging. The
label containing the model number, serial number (S/N) and part number (P/N) is located
on the side of the packaging box.
Each GW2020 Series router is assigned a unique serial number. Record your device serial
number on your warranty card or somewhere you can easily access it. You must
reference your unique serial number (S/N) when you contact your distributor or Virtual
Access support for installation and configuration confirmation or should you request
service on the device.
Figure 1: The GW2021 label showing the serial number
Unpack the contents. There is a matching label located on the bottom of the router.
3.2 Inserting the SIM card
1. Ensure the unit is powered off.
2. Hold the SIM card with the chip side facing down and the cut corner top left.
3. Gently push the SIM card into SIM slot 1 until it clicks in.
4. To remove the SIM card, gently push the SIM card. The card will click out.
3.3 Connecting the antenna
The GW2020 Series router is shipped with one antenna suitable for the model you
ordered. If you require antenna diversity, contact your reseller.
Screw the antenna into the back MAIN SMA connector.
3.3.1 Antenna diversity
The GW2020 Series router has an AUX connector for connection of a second antenna to
allow for antenna diversity. Antenna diversity helps improve the quality and reliability of
a wireless link by mitigating problems associated with multipath distortion.
Multipath distortion is a form of RF interference that occurs when a radio signal has more
than one path between the receiver and the transmitter. It commonly occurs when there
is no clear line of sight between the transmitter and receiver and instead the signal is
reflected off hard surfaces such as shelves, ceilings and walls.
