Currently Resting, Considering my options.

I have always been an engineer at heart but I have also loved getting involved in building relationships (one of my core skills!) and doing some of the 'fluffy' stuff like marketing and event coordination. I also really enjoy public speaking although I dont get much chance at present.

Having left UK Broadband and moved back to West Berkshire I am considering my options. The right opportunity might exercise my 'people' skills more than at previously, or may make use of practical, hands-on skills. I guess I will know the role when it happens as I certainly do not have a 'spec' for it at the moment.

If the right opportunity comes up then I will definitely be interested. I guess my ideal would be based on 3 month contract bites rather than a permanent role.

Principal Engineer

UK Broadband

March 11 - Sept 12

I constructed a prototype lampost mounted box to backhaul our Ruckus Wifi units over our LTE network in Reading

I constructed a prototype long range LTE box by integrating the LTE indoor circuit board on to a long range panel antenna.

Responsible for working with new customers to our LTE service in Southwark, demonstrating LTE Box, installing and supporting.

I was one of the Health and Safety team of three formed to get the company’s health and safety systems up to date including ISO18001 accreditation.

My responsibilities on this team are mainly to do with site working rather than office based H&S. Tasks include writing risk assessments, defining policies for working at height, PPE, RF Safety etc and receiving training in various H&S disciplines.

I 'owned' our Reading WiFi network of 28 Ruckus access points units meshing with each other then backhauling through three Ruckus point to point links to one of our radio sites. This has involved installing, configuring and performance testing of UDP and FTP up and downloads, replacing faulty units, upgrading software and moving p-p links and access points for improved performance.

I assisted in the specification of an on-site cabinet for the deployment of an LTE network, this specification has been mainly centred around minimising power requirements and reducing weight and size of cabinet for agile (and cheap!) deployment.
