Despite incompatibility with existing air-interface standards, late introduction and the high upgrade cost of deploying an all-new transmitter technology, W-CDMA has become the dominant standard. From an engineering point of view, W-CDMA provides a different balance of trade-offs between cost, capacity, performance, and density[ citation needed ]; it also promises to achieve a benefit of reduced cost for video phone handsets.
Mobile User Objective System using geosynchronous satellites in place of cell towers.
Most countries have, since the ITU approved of the 3G mobile service, either "auctioned" the radio frequencies to the company willing to pay the most, or conducted a "beauty contest"—asking the various companies to present what they intend to commit to if awarded the licences. This strategy has been criticised for aiming to drain the cash of operators to the brink of bankruptcy in order to honour their bids or proposals.
Most of them have a time constraint for the rollout of the service—where a certain "coverage" must be achieved within a given date or the licence will be revoked. New Zealand in August and Australia in October Though advancements in its network deployment have been delayed due to the merger with Cingular, Cingular began offering HSDPA service in December Availability only in main cities.
Pricing is approx. These air interfaces are classified as TDD, because time slots can be allocated to either uplink or downlink traffic. Unlike W-CDMA, it does not need separate frequency bands for up- and downstream, allowing deployment in tight frequency bands.
Where very many CRs have to be implemented, or very many specifications are to be produced, a further week beyond the above deadlines may be required. These dates are agreed by the TSG Chairmen.
Over the Christmas and New Year period, when the winter TSG round finishes shortly before the holiday period, an extra week or so is normally added to the final deadlines. To find a particular specification by series, look at the Numbering page.
Revised versions of many of these specifications are produced up to four times a year following the quarterly TSG plenary meetings.
The table below leads to information about: Specifications arising from each plenary TSG meeting, including the latest versions of each specification that was not changed at that meeting.
