In 1898, Sir Oliver Lodge (1851-1940) patented the first syntonic or tuned radio system. Ironically, the very patent that inaugurated this fundamental concept of narrow-band, frequency-domain radio also disclosed some of the first ultra-wideband (UWB) antennas: As charged surfaces or capacity areas, spheres or square plates or any other metal […]

The 313th Regiment resumed its attack on Ambacourt and Poussay this morning, 13 September, 1944. The 3rd Battalion overran the town by 10:30 but was encountering such resistance that the 1st Battalion was ordered to attack from the southeast and the 2nd Battalion from the west.

The 79th Infantry Division halted about noon today, 9 September, 1944, for a three hour rest. At 15:00, the Division continued on the road, driving through the night.
Today, 8 September, 1944, chronic supply problems were finally overcome. The 79th Infantry Division was motorized and ordered to Reims, France. No enemy forces have been encountered-thus the Division continued on the move for 24 hours straight.
The 313th Regiment and the rest of the 79th Infantry Division received orders today, 5 September, 1944 to prepare for a move. Supply problems remain critical, however, and the move may need to be postponed a few days.
The 313th Regiment reached an assembly area just north of the Belgian border at about 03:00 this morning. The rapid advance has created logistics problems. The Regiment is ordered to rest. A USO show is scheduled for 5 September.
High Frequency Direction Finding (HF/DF or “Huff-Duff”) played a critical role in the Second World War. Shore based DF determined the location of German U-boat packs enabling convoys to be routed around them. Ship and airborne DF in conjunction with centimetric radar enabled effective antisubmarine warfare. [1, 2] One of […]
By 09:00 today 2 September, 1944, all elements of the 313th Regiment were across the Somme, motorized, and continuing north throughout the day. The troops encountered cheering crowds, and continued far into the night encountering little enemy resistance.
Today, 1 September, 1944 at 17:00, the 1st Battalion rejoined the rest of the 313th Regiment. Now motorized, the Regiment moved through towns including Handaineville, Flaucourt to the banks of the Somme River. Tonight in cold rain, engineers are working to bridge the Somme.
Here’s another collection of RFID and wireless related links: VeryFieldsRFID has a good introduction and tutorial to RFID. BoingBoing presents a brief historical item on the WWI-era prohibition on amateur radio. Chris Paget’s DEF CON 17 talk on RFID Mythbusting helps dispel myths about RFID range and security: And finally […]
Early in the morning, the The 313th Regiment received orders for movement to the north. The 313th was ordered into division reserve, and the 1st Battalion moved to vicinity of St. Pierre.
It’s been a busy week, so here is yet another RTLS/RFID update: Mark Roberti of RFID Journal has a new blog entry on the RFID Privacy Conundrum.

The 30th Infantry Division moved across the Seine to assist the 79th Division in extending their bridgehead, today 27 August, 1944. The attack began at 16:00. As I’ve been researching and reconstructing my grandfather’s WWII experiences, several books and references have been of particular help: Ernie Pyle’s Brave Men collects […]
Conventional RTLS typically relies on one of three general approaches: Direction Finding (DF): originated by John Stone Stone in 1902, Amplitude Ranging: originated by Lee de Forest in 1904, and Time of Flight (Time Difference of Arrival (TDOA), or Transponder Ranging are typical approaches): orignating in the 1920’s and 1930’s. […]
The 79th Division successfully established the first bridgehead across the Seine today, 20 August, 1944. The Division, including the 313th Regiment, will remain in a defensive position for a while, waiting for the rest of the Army to catch up.
The Second World War spurred further innovation in RF-based navigation. The first wide-scale deployment of an RF-based location system was the Long Range Navigation or “LORAN.” LORAN was an evolution from a shorter range British system called “GEE.” Like GEE, LORAN employed synchronized impulse signal transmissions from paired transmit towers.
