Data rates in the range of several Gigabit/s are needed to transmit signals like uncompressed video signals. Amendment 802.11ad to the WLAN standard defines the MAC and PHY layers for very high throughput (VHT) in the 60 GHz range. The specification 802.11-2016 has defined additional modulation and codings schemes for the 11ad single carrier part to increase the data rate. The OFDM part is obsolete.This white paper provides an introduction to the technology behind 802.11ad and highlights the test and measurement requirements.

LTE Location Based Services (LBS) involve the process of determining where a device is located. Global Navigation Satellite System (GNSS) based solutions are highly accurate and the technology of choice for absolute position accuracy, providing the device has a good line-of-sight, but this is not always the case. A device can be in a highly dense urban environment with reduced satellite visibility or indoors with very low signal levels.These limitations of GNSS systems have meant that LTE cellular based alternatives have been developed within 3GPP Release 9 and onwards.They are described in this white paper.
