SkyBell. Smart video doorbell, based on 802.11n protocol.• Evaluate and test rate control algorithms for data transfer to reach the effectiveness and identify the features of functioning.• Prioritization of data packets of video stream, generated by device, to increase transmitting rate in high density environment.• 802.11 standard consultation.

Long-range outdoor wireless network device with TDD operational mode for point-to-multipoint and point-to-point media.• Design and implementation of functionality for bandwidth management for a specific user, maximum information rate (MIR).• Implementation of mechanism for selecting packets from queues with different priorities, according to the configured percentage (QoS). The algorithm allows efficiently transfer management and high-priority traffic while excludes stopping the selection of packets from any queue.• Improved the quality of data transmission for the channel reuse mode or high-density environment by implementing the algorithm for controlling the threshold of the receive signal level (SNR) on AP and SM side.• R&D and improvement of frame structure for efficient usage of frame duration time.• Preparing and support devices for Dynamic Frequency Selection (DFS) test procedures for FCC and ETSI v1.7.1 certification.• Investigation and testing of data transmission timings using laboratory equipment (oscilloscope, vector signal generator, logic analyzer and spectrum analyzer).• Development of test plans, test automation (Python) and support of technical documentation.

Text editor with additional features for comparison, review and commenting of text documents.• Reduced overall processing time by improving of loading algorithm.• Design and implementation of algorithms for comparison of graphic objects, tables and nested tables, multilevel lists, footnotes and endnotes.• Implementation of algorithm for correct comparison of headers and footers in documents with multiple sections.• Improvement of tracking changes algorithm.• Design and improvement of document saving to RTF format to provide correct saving of documents of any complexity and support up to date standard.• Implementation of document commenting.• Detailed work with RTF v1.9 standard.
