Connectivity

WLAN

Wireless LAN, WLAN, is a network access technology becoming increasingly common around the world. It allows users with portable computers and wireless devices to access network resources wirelessly, at the office, in the home, or in public spaces (public Access Zones or so-called “hot spots”), such as cafés, airports, aeroplanes and hotels.

Sony Ericsson P1 WLAN may be used as an alternative to any other type of network connection, such as, a GSM, UMTS, infrared or Bluetooth™ connection, and it may be chosen as the preferred connection method for any of the Sony Ericsson P1 data applications.

The WLAN functionality is compliant with the IEEE 802.11b standard (11 Mbit/s), and will work simultaneously with Sony Ericsson P1 GSM, UMTS, infrared or Bluetooth connection interfaces.

The WLAN functionality can be switched on or off as required, including when the Sony Ericsson P1 is placed into Flight mode.

The Sony Ericsson P1 allows the user to rapidly make a connection to a public hot spot. A WLAN icon is available on the Sony Ericsson P1 status bar and this icon may be used to open the WLAN set- up screen. The user may then use the WLAN and scan for available networks. A connection to a

chosen hot spot may then be made without the need for entering any technical details about the network.

The phone also uses a feature called “Fast connect” to allow the user to simply enter the encryption key or password when trying to make a connection to an unknown access point that uses WPA-PSK, WPA2-PSK or WEP encryption.

It is possible to use WLAN in conjunction with a personal firewall and virus scanner.

For connection to a private network in the office or at home, Sony Ericsson P1 supports the following encryption/authentication methods:

•WEP

•Shared WEP

•Dynamic WEP

•WPA Personal and WPA2 Personal

Setting up more complex settings for infrastructure and ad-hoc modes is simplified by the use of a wizard that presents relevant options after each selection is made. For example, a WEP key selection screen follows the selection of shared encryption.

Virtual private networks software is supplied for use with WLAN in Infrastructure network mode.

Voice over IP, VoIP

Sony Ericsson P1 comes with enablers for creating a Voice over IP (VoIP) client. This makes it possible to use the phone as a complement to, or even as a replacement for, a fixed phone at home. A Sony Ericsson partner may develop, market and deliver VoIP clients using the audio and network enablers

provided in Sony Ericsson P1. Near-realtime PCM Record & Play, echo cancellation, and access to audio paths are a few examples of enablers.
