Last week, the largest Hungarian telecommunications company, Magyar Telekom and Ericsson, signed a five-year supplier contract, as part of which the Swedish multi can further develop the service provider's mobile network. Through the tender agreement, Ericsson, which has been involved in the construction and operation of all previous generation network infrastructures of Telekom and its predecessors, will have the opportunity to build the operator's 5G network.
Acquired by CountingNews According to internal information, Ericsson and Telekom have so far only agreed on the renewal and further development of the radio access network (RAN), and the tendering process for the replacement of core network elements is still pending. However, this does not prevent Telekom from building a nationwide 5G network with Ericsson technology in the short term, as the next-generation network operates in most countries relying on the 4G core network (this is called 5G non-standalone mode).  eri_5g_o2uk “/>
With this topology, Telekom launched the 5G network as the second service provider in Hungary at the beginning of April in some areas of Budapest and Hungary's first 5G network – which is connected to Vodafone Hungary – also operates in this way, but the supplier in this case is China's Huawei.
Although no tender has yet been issued for the core network upgrade, which is a really big bite, there is a strong chance that this tendency will be the Swedish one, even if the core and RAN elements are no longer typical for new generation networks. degree of vendor lock-in as in previous generations. All this means that in the case of a modern mobile network, the suppliers of the core network and the radio access network can be completely different companies, but on the RAN side, for compatibility reasons, the manufacturer that has previously equipped the operator is in the saddle.
By building access networks, it is much easier for an operator to have relatively newly developed components in his network, because in this case it is not necessary to replace certain hardware components, just upgrade software to add a new function or even a completely new generation of standards.
THERE IS PLACE TO UPDATE ENOUGH SOFTWARE
Ericsson's baseband unit (BBU), for example, has been ready for the 5G upgrade for years, so the control circuits that will be available from 2015 installed in Telekom h can now be made 5G-capable with a software update. In addition, mostly passive elements, typically antennas, need to be replaced or installed by professionals in order for the service provider to be able to serve all generations of technology used by a wide range of subscribers in the ever-expanding spectrum.
Last week's agreement between Magyar Telekom and Ericsson Telekom (and its parent company, Deutsche Telekom) went to the commissioner: Huawei of China also participated in the tender, according to insider information, the outcome was due to unfavorable processes affecting the Asian supplier, which made the manufacturer's European presence uncertain; different pricing (Ericsson was able to give the devices cheaper because the price of services and maintenance was treated as a separate item).
