2. Description of the UR5 router
2.1. Introduction
The UR5 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 UR5 router expands the capabilities of the HC15 module by the option
of connecting more PC’s by means of the built-in Ethernet interface. In addition, the firmware
of the UR5 router provides automatic establishment and maintenance
of HSDPA/UMTS/EDGE/GPRS PPP connection. By means of the integration of a DHCP
server it provides the user with simple installation and Internet access.
In addition, the UR5 router is equipped with a USB 2.0 Host interface which is designed
only for connection to a USB device.
By customer request it is possible to equip the UR5 router with the PORT1 module
and extend the function of the UR5 UMTS router.
Examples of Possible Applications
• 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 network exploits two duplex
techniques – transmission modes FDD (Frequency Division Duplex), which is based
on separate frequency channels (i.e. uplink and downlink uses different channels) and TDD
(Time Division Duplex), which is based on separate time (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 the user to access
the UMTS network.
