As amended HPC.ru got the first PDA that uses as operating a new solution from Microsoft WindowsCE.NET (detailed review of the machines read in the next few days). In this connection, we decided to write about what constitutes a new operating system and how it differs from their predecessors.
As the company says Microsoft, the developers of devices based on Windows CE.NET and users of such devices can have many innovations and improvements over the previous version of OS Windows CE 3.0. Among the major: support for wireless technologies, software emulation of different devices, rich networking and multimedia capabilities. Developers should please the Master platform, which enables plants to use presets to create new devices. Thus, more.
Wireless function
Bluetooth
In Windows CE.NET system is carried out (without installing additional drivers) support for wireless technology Bluetooth, which allows two devices to communicate if they are located within 10 meters of each other. In addition to the CCP, this technology may bring your headphones and headsets, printers, modems, etc. Built-in support will allow, for example, a PDA running Windows CE.NET, use the "sinezubye" cell phones as modems, share files and data with similar devices and join a wireless local area networks.
Object Exchange (OBEX) Protocol
Object Exchange (OBEX) Protocol - an efficient binary protocol that enables devices of different types quickly and without any additional setup to exchange data and files. In Windows CE.NET OBEX works via Bluetooth and IrDA (infrared).
MediaSense
This feature helps the user navigate the wireless networks. MediaSense reported the presence of different applications to the network (ie, whether the user's device within range of a wireless connection) and allows network programs to work off-line.
802.1x/Zero Configuration (Zero configuration)
This feature was first included in the operating system Windows CE. It simplifies the process of connecting to wireless networks, 802.11, and built an extended authentication protocol (Extensible Authentication Protocol - EAP) provides greater job security in such networks, verifying a user name and password, digital certificate, as well as allowing OEMs to use its own funds protection.
Windows CE.NET - Open communication platform
Lightweight Directory Access Protocol (LDAP)
This protocol is used to access Microdoft Active Directory, where users can remotely store addresses, phone numbers, descriptions of upcoming meetings and other personal information.
Remote Access Service (RAS) Server
Windows CE.NET can remotely connect to devices running Windows CE with the help of broadband networks and manage them.
TCP / IP
The presence of a standard TCP / IP protocol allows PDA Windows CE.NET is not only connected to local and global networks, but also to serve in their servers.
Universal Plug and Play (UPP) Device Host and Control Point
This protocol makes it easy to connect peer-to-peer PCs, wireless and other "intellekutalnyh" devices in a network. UPnP Control Point allows the PDA to locate and control any device that supports Universal Plug & Play.
Remote Desktop Protocol ...
... allows from a PDA to manage processes on your desktop PC using LAN, WAN, коммутирумого access, ISDN, DSL or VPN.
System changes
To ensure reliability in the core of the system was included compact control system processes and functions to prevent the stop priority processes. To make the system takes as little space has been increased its "fragmentation" - all useful functions raznenseny for individual modules, which are razarbotchik mobmlnogo device may or may not use their own choice. The very same nucleus - a necessary component - is a new OS just over 200 kb. Windows CE.NET is supported by most modern processors: ARM (ARM720T, ARM920T, ARM1020T, StrongARM, XScale), MIPS (MIPS II/32 with FP, MIPS II/32 without FP, MIPS16, MIPS IV/64 with FP, MIPS IV / 64 without FP), SHx (SH-3, SH-3 DSP, SH-4), X86 (486, 586, Geode, Pentium I / II / III / IV). By sraneniyu with the previous version improved security system. In Windows CE.NET using Kerberos Security Protocol, Secure Sockets Layer (SSL) for network communications, encryption with smart cards.
User Interface
The new OS will provide and developers and users more options for customizing and personalization of the interface. Poddezhrzhivaetsya: Customize the appearance of control, profiles, simultaneous work on multiple monitors, fonts, Clear Type, a custom directory for loading fonts (fonts in a PDA with Windows CE.NET can be stored on a memory card).
Multimedia
Finally, the new operating system boasts a rich multimedia capabilities. There is full support for Direct 3D, interactive three-dimensional applications, DVD-Video (with appropriate hardware read only memory on the Windows CE.NET will be able to play movies at DVD quality is no worse than the one which offers a home player. Pooderzhivaetsya also DiriectX and Microsoft DirectMusic. The new OS will also be transferred to handheld computers all codecs Windows Media Player eighth version of the system and the DRM (Digital Rights Management).

The included OS web-browser will now be recognized by servers as Microsoft Internet Explorer version 5.5. All the above - only a few basic characteristics of the new OS. Full list of features and changes compared with earlier versions can be found here. In addition, all this is only a theory, proposed by Microsoft. How the device with Microsoft Windows CE.NET operating "in life" you can learn in the near future: on our website will be posted review of the first into our PDA edition of the OS, the Korean DOT320.
