A few weeks back, a friend posted on Facebook that they had returned from a run and lost 2 miles on their tracker. They were disappointed. We have become addicted to measuring our fitness, and want full credit for every step.
I’ve been diligently tracking my daily mileage covered while on foot at #MWC2014. The conference venue is huge with 8 halls covering an area the size of 14 European football fields or 19 American football fields. Yesterday, I thought I would make a significant leap when I ran down to Hall 3 to visit #Cisco from our booth in Hall 7. But when it all came down to it, my distance covered improved slightly with 3.1 miles logged or 4.96 kilometers (it sounds better in metric).
But today, I suffered a big disappointment when the system stopped registering progress at 0.88 miles. It has been at the same distance since 10 am this morning and I’ve been to Hall 2 and back, and deep into Halls 3 and 5. So there are missing miles because GPS signal was lost for most of the day, and there could be lost miles from the first 2 days (I feel like I’ve run a few marathons and my feet are not my own anymore). At one point, I headed outside to see if it would pick up GPS signal and rectify the situation, but that was unsuccessful.
With service providers looking to deploy small cells indoors and outdoors, the choice of timing solutions in network equipment will bear great importance. Urban canyons and indoor deployments favor network based time solutions such as 1588v2 (IEEE 1588-2008) or Synchronous Ethernet (SyncE).
The PTP 650S point to point solution leverages 1588v2 and SyncE to backhaul Small Cell traffic and provide reliable timing for 3G and 4G / LTE networks.
