You&#x27;ll get about 10 metres in an office with cubicles with chest high partitions.  Page 6 of the paper &quot;A High Speed Wireless LAN&quot; by Skellern, Lee and others in the Jan&#x2F;Feb 1997 edition of IEEE Micro has a diagram showing coverage for OFDM in a typical office at a centre frequency of 40GHz.  60GHz will be worse than this, as oxygen in the air absorbs 60GHz quite stongly [2].  I&#x27;m not sure how the power transmitted by 802.11ad compares to the above measurements, but the measuremensts in the paper were taken with 60GHz WiFi in mind, so they should be representative.<p>[1] <a href="http:&#x2F;&#x2F;www.jwdalton.com&#x2F;papers&#x2F;ieee_micro_1997_wlan.pdf" rel="nofollow">http:&#x2F;&#x2F;www.jwdalton.com&#x2F;papers&#x2F;ieee_micro_1997_wlan.pdf</a><p>[2] <a href="https:&#x2F;&#x2F;transition.fcc.gov&#x2F;Bureaus&#x2F;Engineering_Technology&#x2F;Documents&#x2F;bulletins&#x2F;oet70&#x2F;oet70a.pdf" rel="nofollow">https:&#x2F;&#x2F;transition.fcc.gov&#x2F;Bureaus&#x2F;Engineering_Technology&#x2F;Do...</a><p>---<p>Edit for clarity.
