Tele2 and Telenor joins forces in coming LTE network

Interesting enough these two operators have previously not cooperated together in their network building, instead there has been two blocks with 3 and Telenor on one side for the UMTS and Telia + Tele2 on the other side. But since Telia is building their own network and the operator 3 decided to stick with UMTS for the time being the left over operators Tele2 and Telenor have decided to form a new partnership.

I find this really interesting and I think it will be a good thing for the customers pricewise in the end since competition will start on several fronts at the same time. The differences between one operator and another will probably become more and more blurry as these cooperations proceeds.

Swedish papers dubs LTE ”Super 3G”

Apparently Swedish news papers have dubbed the LTE technology developed by among others Ericsson to ”Super 3G” and are waiting to call it 4G.

I have heard rumours that Ericsson internally are very careful not using the term 4G on LTE but waiting for LTE-Advanced with even higher bitrates to see if it is deserving the designation.

Super 3G gives the impression that it evolves from Turbo-3G which is not really the case, this is a new radio system and although some things such as MIMO actually was specified in HSPA it still was not in widespread use as it will probably become in LTE.

LTE can deliver a gross maximum bitrate in the downlink pushing 300 Mbit/s and LTE-Advanced is said to be pushing towards the 1 Gbit/s which would be really getting mobile broadband to take off.

For me the major hurdle is the uplink however which in all systems, today as well as LTE systems are considerably lower in bitrate than the uplink. This limits the use for mobile applications that transmits lots of data (video cameras) and the industry is looking for cheap way of communicating with cameras in vehicles such as taxis, buses and trains and even with a good coverage for LTE it will not be enough.

Frequency Allocation in the Swedish 2.6 GHz band

This is the current allocation of the Swedish 2.6 GHz band after the frequency auction among the operators for the emerging 3G+ services such as WiMax and LTE to be used in Sweden. More bands are likely to follow.

[TABLE=2]

Duplex distance for FDD bands are 120 MHz. Uplink covers UARFCN 12500-12850 and downlink is 13100-13450 and the TDD band is 12850-13100.

The 50 MHz TDD band in the middle between UL/DL portions of the FDD band is thought to be used for Wimax in the future. Intel Capital Corporation will probably work together with some operator to provide WiMax coverage in this band.
