Microsoft Rural Airband Initiative: technology and patents

Microsoft believes the U.S. can bring broadband coverage to rural areas within a 5-year time frame, based on a strategic approach that combines private sector capital investments in new technologies with public sector support.  Microsoft further believes that other countries can use the same approach to bring broadband coverage to their rural areas over time.  To accomplish this goal, we are prepared to invest in and catalyze broader market adoption of this new model through our Airband technology program.  The Airband program offers businesses, non-profits, and government organizations royalty-free access to over 50 Microsoft patents, along with sample source code related to technology we’ve developed to better enable broadband connectivity using TV white space spectrum in rural areas.

Microsoft White Space Patents and our patent pledge

Microsoft promises not to assert any of the White Space Patents listed below against any person or entity for their efforts to provide or support the provision of internet access to rural or underserved markets. Microsoft may occasionally expand the list as it procures additional patents directed towards TV white space technology.

How Exchange ActiveSync Works

The Exchange ActiveSync protocol is the language spoken between a mobile device or tablet and a messaging server, enabling synchronization of pre-defined objects. The EAS protocol allows devices to synchronize email, calendar, contacts, and tasks over the air with Microsoft Exchange, Outlook.com and other servers which implement the protocol.

Syncing is the process of reconciling differences between data stored on a device and on the Exchange Server. A mobile device or tablet will have its own email, contacts, calendar, and task applications, maintaining its own collection of objects and changes made since its last sync with the Exchange Server.

The device may initiate a new sync by sending a set of updates to the Exchange Server and requesting the Exchange Server respond with its own updates. The Exchange Server processes updates it receives, resolves any conflicts, and sends its changes back to the mobile device.

OEMs, application developers and service providers can license Exchange ActiveSync for use on their own devices, software, or servers.

Benefits of EAS

Broadly licensed protocol

Many OEMs and software developers have licensed EAS. Many of the world’s most widely used email clients adopt EAS to sync email and other data with top messaging servers.

How exFAT works

The exFAT file system handles large files, such as those used for audio and video media. It allows efficient storage and seamless data portability between desktop PCs and consumer electronic devices, enabling easy interchange between the two. Inheriting its base from FAT32, another Microsoft file system, exFAT can be implemented with minimal effort. Companies can also choose to add transaction support to their exFAT implementation (TexFAT) to assist with transaction-safe operations. exFAT has been included in Windows operating systems since Windows CE 6.0 and Windows Vista SP1.

Our exFAT licensees

More than 100 companies license exFAT, including some of the world’s best-known and most innovative OEMs. exFAT is used by the Secure Digital (SD) Card Association for high-capacity, high-speed SDXC and SDUC cards.

Direct license with exFAT implementation

Microsoft has agreements with several industry leaders that allow them to provide exFAT implementations directly to customers along with a direct license from Microsoft. These leaders can offer highly tuned implementations to provide the best end-customer experience and include warranty and support. This offering is available through the following companies:

How RDP works

RDP allows users of a remote client to connect securely to a server or virtual machine over a network. RDP connects with, and channels communication between, components of remote clients and servers. RDP is a multi-channel protocol, with separate virtual channels carrying different types of data. These include graphics data, keyboard and mouse user input, device communication, file system, audio and video, and licensing information. The RDP protocol has applications in secure business and government network solutions, including where an encrypted desktop is required. RDP client software is also built into Windows Pro and Enterprise.  For developers building remote desktop client applications for computers, phones, tablets, or other devices, Microsoft Technology Licensing (MTL) offers a technology license for the RDP protocol set.

RDP features

Remote Desktop Protocol (RDP)

Although a technology license is required to integrate the RDP protocol into a device, the RDP product documentation describing the RDP protocols is freely available on the Microsoft Developers Network.

Our RDP licensees

Microsoft licenses RDP globally to several customers developing remote desktop, cloud, and device solutions.

How SMB works

SMB is a client-server system. It provides a protocol for exchanging data packets between the client device and the server. Data packets may control sessions with the server, allow users to remotely access and edit files and directories stored on the server, and perform functions such as printing documents or authenticating users.

SMB is critical to ensuring that enterprise-level servers are secure and interoperable with the networks they serve. Other applications of SMB include peripherals such as printers and scanners, security cameras, televisions, and some mobile devices.

Traditionally used in local area networks, SMB can also be used to transmit data over virtual private networks and to cloud-based solutions. SMB is implemented in Microsoft Windows as Microsoft SMB Protocol.

SMB features

SMB Implementation

While a technology license is required to implement SMB, Microsoft publishes documentation about the SMB protocols:

Direct license with SMB implementation

Microsoft has an agreement with an industry leader, Visuality Systems, that allows them to provide SMB implementations directly to customers along with a direct license from Microsoft. Visuality Systems offers highly tuned implementations to provide the best end-customer experience and include warranty and support.

Our SMB licensees

Microsoft Technology Licensing offers licenses for SMB Client and SMB Server stack utilization implemented according to our protocol documentation in storage systems, a variety of devices, and software applications.

Executing a VC-1 Patent Portfolio License

As you might be aware, WMV-9 from Microsoft conforms to the VC-1 standard. Thus, every company implementing WMV-9 products or content should consider the benefits of executing the VC-1 Patent Portfolio License. The VC-1 Patent Portfolio License, which is the Microsoft-preferred method of licensing the patents in this technology, grants a license to VC-1 essential patents from many companies (including Microsoft) and thus provides additional coverage and value for WMV-9 implementers.

Find out how to request a VC-1 Patent Portfolio license through MPEG-LA

Note: Distributions of Final Products containing implementations of the WMV codec are royalty-bearing, although those royalties are substantially discounted for licensees of the VC-1 Patent Pool.
