Next Generation mmWave Systems: Requirements and Applications

This presentation by James Gilb from Tensorcom explores the requirements for future mmWave wireless systems, highlighting advancements from 802.11ad which offers up to 7 Gb/s with low power consumption. The discussion emphasizes the need for small form factor devices, particularly in mobile applications, where billions of devices annually demand high-speed connectivity. Moreover, it examines emerging requirements for mmWave systems including higher data rates over 40 Gb/s, MIMO, and improved power efficiency to support the growing demand for wireless applications.

  1. Requirements for Next Generation mmWave Systems Authors: • Date:2014-01-21 James Gilb, Tensorcom

  2. Abstract • This presentation discusses application requirements for next generation mmWave wireless systems. James Gilb, Tensorcom

  3. Current state of 802.11ad • 802.11ad provides for up to 7 Gb/s at low power • There is a complete SoC with < 250 mW peak power • Commercially available implementations with up to 4 Gb/s • Multiple vendors have announced products or product development • Small form factor • Complete implementation including antennas in < 12 mm x 12 mm • 802.11ad complements 802.11ac in mobile devices • 802.11ad offers low power, small form factor for short range • 802.11ac provides legacy compatibility and better performance than 802.11n • Fast session transfer allows seamless 802.11 experience James Gilb, Tensorcom

  4. Applications • Mobile applications are expanding area • Billions of devices every year • Tablets and smart phones will be volume leaders • Wireless connectivity enables these devices • Mobile devices have different constraints • Small form factor required • Limited room for antennas • Restricted peak and average power available • Backwards compatibility is a key factor • Build on existing infrastructure with 802.11a/b/g/n James Gilb, Tensorcom

  5. High-speed Wireless Applications • One of the key applications is to cut the cable • Data rates for cables keep increasing: • USB • 3.0 – 4 Gb/s, full duplex (5 GS/s with 8b/10b coding) • 3.1 – 8 Gb/s, full duplex (bonds 2 channels) • Thunderbolt • 1 – 10 Gb/s, full duplex (10.3125 GS/s with 64b/66b coding) • 2– 20 Gb/s, full duplex (bonds 2 channels) • Uncompressed video • 1080p, 24 bit, 60 Hz – 3 Gb/s • 4k, 24 bit, 60 HZ – 12 Gb/s James Gilb, Tensorcom

  6. New requirements • Build on 802.11ad’s current success • Higher data rates - > 40 Gb/s throughput • MIMO • Channel bonding • Enable lower power modes • Evaluate modulation for peak power reduction • Low power SC mode is an example • Improvements for average power reduction James Gilb, Tensorcom

  7. Conclusions • Mobile devices and applications are increasing rapidly • Wired connectivity speed is continuing to increase • Wireless needs to keep up • 802.11 should start looking at the next generation of mmWave systems James Gilb, Tensorcom

  8. Straw poll • What should be the next data rate for 802.11 in the 60 GHz band? • 20 Gb/s • 40 Gb/s • 100 Gb/s • No new work in 60 GHz band James Gilb, Tensorcom
