2. Description of the MR36 router
2.1. Introduction
UMTS router MR36 is a compact electronic device based on the HC15 module
of SIEMENS which enables data transfers using HSDPA/UMTS/EDGE/GPRS GSM, GPRS
and UMTS technologies.
Primarily, the MR36 router expands the capabilities of the HC15 module by the option
of connecting more PCs by means of the built-in Ethernet interface. In addition, the firmware
of the
MR36 router provides automatic establishment and maintenance
of HSDPA/UMTS/EDGE/GPRS PPP connection. By means of integration of DHCP server it
provides the users simple installation and Internet access.
In addition, the MR36 router is equipped with the USB 2.0 Host interface which
is designed only for connection to USB device.
By customer request it is possible the router MR36 equip with module PORT1 and
extend function of the UMTS router MR36.

2.2. UMTS technology
For radio terrestrial part UMTS (Universal Mobile Telecommunication System), which is
marked as UTRA (UMTS Terrestrial Radio Access), is warranted 155 MHz band in frequency
band about the 2 GHz. It is bands 1900–1980 MHz, 2010–2025 MHz and 2110–2170 MHz.
The UMTS system is based on code solution of carried channels – use the access
method WCDMA (Wideband Code Division Multiple Access). WCDMA exploit direct spread
spectrum DS (Direct Spread). For transmission the UMTS networks exploits two duplex
techniques – transmission modes FDD (Frequency Division Duplex), which is based
on frequency channel separate (i.e. uplink and downlink uses different channel) and TDD
(Time Division Duplex), which is based on time separate (i.e. uplink and downlink uses one
channel, in which both direction are changes in time).
UMTS network consists of three basic entities:
• Basic network CN (Core Network) – own core of network
UMTS,
• network UTRAN (UMTS Terrestrial Radio Access Network) – the radio access
network
,
• users part UE (User Equipment) –
entity, which allows access to
network UMTS to user.
