You can find the background information for this article in the post “Sharing Bandwidth: Cyclic Prefix Elimination.”  Most wireless transmissions use a modulation technology called OFDM (orthogonal frequency-division multiplexing). This method was invented by Saltzburg and Chen at Bell Labs in the 1960s, but was not widely commercialized until the 1990s when faster signal processing […]

Unfortunately, there is only so much over-the-air wireless bandwidth, and it must be shared between a lot of folks. And the situation is not getting any better.  While you can usually run another wire or fiber optic cable between two locations to get more bandwidth, if you have a wireless application you must share this […]

Season’s greetings! As we get our annual lists together, here’s one I bet you forgot: Spectrum. But, I’m sorry to tell you, without spectrum that shiny new iPhone X won’t live up to its potential. Spectrum is the fuel for our wireless communications revolution. It is the bandwidth in the sky – literally, we’re talking […]

If you’re in a technology role in the cable industry, you’re probably aware that cable is undergoing a tectonic shift from “the future is wired” to “the future is wireless.” Wireless means a lot of things to a lot of people. In the past, wireless meant Wi-Fi if you were talking to a cable nerd. […]

It’s World Wi-Fi Day! Really, given how much we work on Wi-Fi technology, every day is Wi-Fi Day at CableLabs. Since the rest of the world has decided to take note, it feels a bit like New Year’s. So, how about a couple of resolutions? In the coming year, we in the Wi-Fi industry should resolve […]

What is the 3.5 GHz Citizens Broadband Radio Service? Last year, the U.S. allocated 150 MHz of spectrum for fixed and mobile broadband use under the newly-created Citizens Broadband Radio Service (CBRS) in the 3550-3700 MHz band. To put 150 MHz of bandwidth into perspective, this is roughly equivalent to the total spectrum that each […]

Today, twenty-three network operators published a white paper to guide the industry on priorities for NFV to deliver the industry vision for 5G systems: “Network Operator Perspectives on NFV priorities for 5G”. The network operator co-authors include Bell Canada, BT, CableLabs, CenturyLink, China Mobile, China Unicom, Colt, Deutsche Telekom, KDDI, KT, NTT, NTT DOCOMO, Orange, […]

The recent announcement by the Wi-Fi Alliance of the new certification designation, Wi-Fi CERTIFIED Vantage™, is a significant step for the industry.
