White Paper, September 2002

Bearer characteristics

The phone accesses WAP services over IP, where

IP is provided over GSM Data.

GSM data access

•Circuit connection of data calls mean that the phone is connected during the WAP session.

•Connection-oriented WAP uses error recovery services to provide high reliability.

•Higher transmission speed than with SMS access.

•Pricing of GSM data access comparable to that of data calls in the network.

•Suitable for Complex Pull services, Browsing and Data transfer.

•Not suitable for Provisioning, Pager service.

•Connectionless WAP can also be used for those networks that do not support connec- tion-oriented WAP.

Connection-orientated WAP

The T600/T602 supports connection-oriented WAP over GSM Data. In general, this means that the connection between the WAP browser in the phone and the WAP Gateway is maintained in a session with error recovery services. This gives a high reliability with a reduced risk of errors in the transmission, and improves efficiency in WAP browsing.

Security using WAP

The T600/T602 is based on the WAP 1.2.1 specifi- cations where security functionality is specified with a technology called Wireless Transport Layer Security (WTLS).

The WAP protocols that handle the connection, its transport and its security are structured in proto- col layers. The security is handled by the WTLS layer operating above the transport protocol layer. The WTLS layer is modular and there are WTLS classes that indicate which security level is sup- ported by the application.

•WTLS class 1 specifies an encoding of the information.

•WTLS class 2 includes class 1 and in addition a server authentication, where server certifi- cates are needed in the phone (access lock)

The T600/T602 supports WTLS class 2.

T600 specifications

The Sony Ericsson T600 is a notable mobile phone that emerged in the early 2000s, characterized by its blend of innovative features and sleek design. As part of Sony Ericsson's T series, the T600 quickly gained popularity due to its compact dimensions and user-friendly interface, catering to the evolving needs of mobile users at the time.

One of the standout features of the T600 was its lightweight construction, weighing in at just 90 grams. This made it one of the more portable options on the market, appealing to users who valued convenience and ease of transport. The phone also boasted a flip design, which not only added an element of style but also helped protect the keypad and screen from accidental damage.

In terms of display, the T600 features a 1.8-inch CSTN screen with a resolution of 101 x 80 pixels. Although modest by today's standards, the display was adequate for the time, offering users clear visibility of their calls, texts, and other functions. The phone supported a range of colors, making it visually appealing to a younger audience.

The T600 was powered by Ericsson's proprietary technology, which allowed for reliable connectivity and voice quality. It was compatible with GSM networks, supporting both 900 MHz and 1800 MHz bands, thereby ensuring coverage in many regions around the world. Battery life was another strong point, with the T600 capable of up to 300 hours of standby time and around 10 hours of talk time, allowing users to rely on their devices for extended periods without frequent recharging.

Additional features included an address book that could store up to 250 contacts, an integrated calendar, and SMS capabilities, enabling users to manage their communications efficiently. The phone also featured a custom ringtone option, allowing users to personalize their device with unique sounds, which was quite popular among teens and young adults at that time.

Overall, the Sony Ericsson T600 encapsulated the essence of early mobile technology, delivering essential features in a compact and attractive package. Its combination of style, functionality, and reliability made it a memorable choice for users seeking a capable mobile phone in the early 2000s. Even today, the T600 remains a nostalgic piece of technology for many who experienced its charm.
