NHS WannaCrypt postmortem: Outbreak blamed on lack of accountability


Don't throw NHS money away in worthless consultancy and reports where boards have neither time to digest or resources to implement doubtful and costly recommendations. Instead fund staff to keep systems updated and ensure known vulnerabilities are not left available for exploit.

Where's the report that identifies primary infection vector? At our affected GP's this appears to be PCTI Docman EDT systems - someone should be working this backwards to find case zero.

Customer: BT admitted it had 'mis-sold' me fibre broadband


Can't tell their arse from their armpit :(

Mirrors my own experience.... Infinity2 ordered in August, 'delivered' in early September. Line check reveals G-ADSL synch and unsurprisingly no change to speeds. Hours spent talking to BT and the story changes from "you have Infinity2 and thats how fast it will go" to "Infinity is not available at your address". Engineer attends at end of September and says "Your still connected to ADSL in the exchange", which I've been trying to explain to BT Technical and Call centre staff since the off. It takes another two months and many exasperated calls to finally get the Infinity connected. The final explanation is that there is a break down between Sales ordering system and Openreach's provisioning system, which blocked the upgrade order. End result decent 56/10Mbs, but BT Sales still say my line is not fast enough to order UHD services! Time to defect to the Evil Murdoch Empire....

Beamforming Via Directional Array

There is a major difference between 'on chip' beamforming included in 802.11n and 802.11ac standards and Ruckus's directional antennae arrays. The conventional 'on chip' uses signal phasing and omni directional antennaes and may under best circumstances give 1-3dB gain if the client is in just the right spot. The directional antennae array has multiple directional antennae elements and some very nifty RF management software which picks the most favourable pair of elements for each client transmission, resulting in +7dB gain.

This results in very significant performance improvement, particularly at range. In a flood coverage deployment you need less points to cover the same area - Ruckus claim up to 40% less.

Whilst I won't blindly recite the sales mantra, we regularly install and test/survey WLANS from all the established manufacturers. Our Ekahau site survey and Chanalyzer tests consistently show that Ruckus system performs significantly better.

Pantentable - Yes it is and has been, and as a technology innovator Ruckus hold many other patents reflecting its own investment in R&D. As opposed to many of the bigger 'manufacturers' who acquire and sit on the intellectual property of others.
