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.
Examples of Possible Application
•mobile office
•fleet management
•security system
•telematic
•telemetric
•remote monitoring
•vending and dispatcher machines
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.

2.3. HSDPA technology (High Speed Download Packet Access)
HSDPA is improved and extended version of the UMTS-TDD. HSDPA is availability
both for UMTS FDD and for UMTS TDD. HSDPA raise essentially bit rate for downlink. It is
attainment on the programmer level. It is doubling capacity on stations BTS, the basic radio
stations, that allow to process data and signal from more users at one moment. HSDPA is
based on a few innovations of network architecture; because of wheeze it is gets lower
latency, faster reaction on channel change quality and processing of H-ARQ (Hybrid
automatic repeat request) on transmission repeat. Transports channel for HSDPA effectively
uses available frequencies, on which transmits data along packets together. After it these
packets pools among individual users by the help definite algorithms.

•CS bitrate – 64/64 kbps
•PS bitrate – 384/384 kbps
•supports W-CDMA FDD (Wideband - Code Division Multiple Access Frequency Division
Duplex) standard
2.9.2. Control microcomputer
The core of the MR36 router is a 32-bit microprocessor Motorola MCF5329 with 16 MB
RAM, 4 MB FLASH EEPROM, serial interface RS-232 and an Ethernet interface 10/100
Mbit/s. The microcomputer is connected to the HC15 OEM module through the USB interface
and controls the communication via HSDPA/UMTS/EDGE/GPRS UMTS. Towards to the user
it is connected on the Ethernet interface.
The software is built on the uClinux operating system.
For the connected devices the modem provides the DHCP service (Dynamic Host
Configuration Protocol) which enables individual clients (computers) to achieve the TCP/IP
configuration when being put into operation. The IP address is set with the assistance of
MR36.
Thanks to the NAT function (Network Address Translation) the modem enables sharing
of the Internet connection by many computers. NAT translates the internal network addresses
and enables each user in the network a transparent access to the external web via a single IP
address. NAT is mechanism which allow reduction of needed quantity unique IP address.
In addition the modem supports the possibility of creation of a GRE tunnel for
connection of two remote LANs to one LAN, which is apparently homogenous. GRE – General
Routing Encapsulation protocol is used without encryption. While using GRE tunnel must exist
on the second side of tunnel equipment buttressing GRE tunnel, for example PC with OS
Linux, CISCO router or MR36.
MR36 dispose function Port Forwarding, it’s improvement of tunnel for forwarding
data’s on port another’s equipment.
Security of data transmission is design by the help of services IPSEC (IP Security).
Service IPSEC provides authenticity check of both knots and security of the encryption carried
data. For protections trustworthiness of data it is using symmetrical encryption.
The modem settings are saved in the FLASH EEPROM memory. All configuring
of the modem can be done through a web interface (HTTP) which is security passwords.
