T-Mobile begins in Rotterdam with his trial, with wi-fi hotspots for customers only in Rotterdam. The hotspots to customers faster internet access and 3g network system. Only 20 percent of the customers in T-Mobile has a phone that is suitable for the wi-fi hotspots.
The wi-fi network with the name WifiZone works over the 5GHz band, probably because the 2.4 GHz band in the centre of a city is often crowded. The phone must be appropriate for that band: the iPhone 5, Galaxy S series from Samsung since the S II and recent high-end devices from other manufacturers are compatible, but older and cheaper devices may not be on the wi-fi network. This is a significant part of the in the Netherlands used phones unsuitable for the wi-fi hotspots. T-Mobile says to Tweakers that about 20 percent of the phones is suitable for the wi-fi hotspots. “But that number will increase rapidly”, says spokesman Michael Fox. “Because many of the now sold phones have support for wi-fi at 5GHz.”
The use of the wi-fi hotspot, in contrast to what the provider said to not affect the data bundle. That happens ‘in any case’ not during the period that the test runs, says the provider against Tweakers. This allows the provider the option to open that later, when the trial is over. T-Mobile does it on his own page that is not yet certain whether the wi-fi hotspots continue to exist: “Since this is a test, can T-Mobile do not guarantee that these services after the end of the test remains.”
There are three hotspots in the centre of Rotterdam: one on the Schouwburgplein, one on the Lijnbaan and the Beurstraverse. Customers can automatically log in with their phone on the hotspot authentication via the sim card, so let the provider know. That goes through EAP-sim authentication. Users with an Android device need to have a separate app download to hotspot to use.
The experiment of T-Mobile is one of the ways in which a provider 3g network, can relieve. Due to the rapidly increased number of users and usage of 3g and the limited capacity of wireless networks have providers of trouble to users on busy places and moments fast mobile internet to continue to offer. Providers also experiment with the prioritization of traffic, but T-Mobile is also 3g on the 900MHz band
