Point-to-Point Wireless

Licensed-exempt bridges carrying voice, video and data where no fixed infrastructure exists — with the encryption placed above the link rather than inside it.

Also known as PtP, 802.11a Bridging, Backhaul

Left to right is time. Each row is one of the 10 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

Point-to-point bridging across backhaul, deployable and municipal applications.

The SOCOM transportable kit is the clearest case: an 802.11a bridge pair spanning two sites with an IPsec tunnel between Cisco PIX firewalls running over the top of it, because in 2003 the radio’s own protection was not something to stake a deployment on and the encryption belonged above the link rather than inside it.

Also the backhaul for the Cisco-partnered mesh pilot, from an existing city tower to the anchor community building over licensed-exempt bridges.
