Eurotel Praha 3G WCDMA Network, Czech Republic

Key Data

Eurotel Praha, spol. s.r.o., one of the leading mobile telecoms operators in the Czech Republic, has launched the country's first WCDMA 3G network based on IMT-2000.

The first phase of the network delivered 3G services to the two largest population centres - Prague and Brno - beginning in the last quarter of 2005. The second phase rollout to the rest of the country is taking place in the first half of 2006 and will expand the 3G network rapidly to other parts of the country.

The new network will allow Eurotel Praha to expand its current services and to launch new services such as mobile TV, live video, full-track music downloads and video calls.

Nokia was awarded the contract for deploying the WCDMA 3G network in September 2005 (the first Nokia 3G contract in the Czech Republic) and was able to install the infrastructure for the new network in record time allowing the launch of new first-phase services on schedule at the end of 2005.

Eurotel Praha currently has two fully operating networks, the 900MHz / 1,800MHz and 450MHz (CDMA2000 1 × EV-DO high-speed internet), which cover 99% of the Czech Republic's 10 million population. The company reported having over 4.5 million customers at the end of September 2005 prior to the new 3G network launch. Eurotel Praha is 100% owned by Cesky Telecom the Czech Republic's main fixed line telecoms operator.


In October 2005 Nokia also carried out tests in conjunction with Eurotel Praha with HSDPA technology. The two companies were able to complete an HSDPA call reaching 1.8Mbps download speed in Eurotel Praha's live network using Nokia's 3G network technology. This technology will allow an even faster network and more new services such as video call, Internet browsing and high-speed broadband mobile data services and file transfer. Czech Republic consumers can look forward to faster HSDPA services in the next stage of their mobile telecoms development in the near future.


Nokia will provide its latest technology to Eurotel Praha for the new WCDMA network, including radio and packet core networks with the state-of-the-art 3GPP Release 4 MSC server system, Nokia Flexi Intelligent Service Node (ISN), Nokia IP Multimedia Subsystem (IMS) and HSDPA-ready Nokia Ultrasite WCDMA base stations. Nokia is also providing the Nokia NetAct network management solution and a range of services for network planning and implementation, operation and maintenance, and training.

At a later stage the Nokia supplied system can be enhanced to HSDPA operation by applying a software upgrade to the WCDMA 3G network, which will give significantly faster download speeds. This will also enhance the efficiency of the network to support a higher number of users at a lower cost per user. HSUPA with enhanced upload speeds will also be available in a similar manner.


During 2005 Eurotel Praha introduced 'Push to talk over Cellular' (PoC) services from Nokia. Nokia also provided the implementation and care services for the system along with their PoC capable 5140 mobile handsets. This new service has allowed Eurotel Praha to introduce real-time direct one-to-one and one-to-many voice communication service in the cellular network.

The principle of Nokia's 'Push to Talk' PoC service is an 'always-on' connection, where calls can be started to both individuals and talk groups with just a push of a key. The call connection is almost instantaneous and the receiver doesn't have to answer the call.

The Nokia Push to Talk service is an integral part of the IP Multimedia Subsystem (IMS). It is based on half-duplex VoIP technology over mobile networks. Due to the IP technology, the Push to Talk service uses cellular access and radio resources more efficiently than circuit-switched cellular services, reserving network resources only for the duration of talk spurts instead of for an entire call session.
