New FCC chairman: Net neutrality rules were a 'mistake

The U.S. Federal Communications Commission's net neutrality rules, passed two years, ago were a "mistake" that caused uncertainty for the broadband industry, the agency's new chairman said.

The net neutrality rules, along with the FCC's decision to reclassify broadband as a regulated common carrier, "deviated" from the U.S. government's longstanding light-touch regulatory approach toward the internet, FCC Chairman Ajit Pai said Tuesday at the Mobile World Congress in Barcelona.

Two years after the agency passed its net neutrality rules "it has become evident that the FCC made a mistake," said Pai, a Republican. "Our new approach injected tremendous uncertainty into the broadband market. And uncertainty is the enemy of growth."

How to identify and resolve double-NAT problems

The digital world is all about IP (internet protocol) addresses. Every device needs an IP in order to communicate on the internet or within a private network. Given there’s not enough public IP addresses out there for every internet-connected device (at least with IPv4), this little thing called NAT becomes extremely important. It stands for network address translation (NAT) and is a function provided by routers to enable multiple devices to access the internet via a single public IP address.

Behind each public IP, there can be hundreds of devices with their own private IP addresses, thanks to NAT. And almost all equipment that provides the NAT function includes a firewall to protect the private IPs and devices from public IPs and devices on the internet. Other network services are also typically offered, like DHCP (dynamic host control protocol) to give out the private IP addresses to devices that connect to the local network.

Intel showed how 5G networking will power VR and self-driving cars

Think about how annoyed you get when you lose your cell signal, and you can see why Intel is pushing for advances in the next generation of networking, also known as 5G. Sure, the company stands to profit from making chips and networking equipment to support faster broadband. Consumers, too, stand to benefit from a future where more things in their lives are connected. To get there, though, we’re all going to need more bandwidth.

At Mobile World Congress, Intel demonstrated several initiatives for developing 5G capabilities. Watching virtual reality’s often stuttery video can make people queasy, but Intel demonstrated how 5G could let you stream 8K VR content. The company also showed how self-driving cars will need a speedy 5G network to communicate with other cars and infrastructure so they can move safely.

India's Reliance Jio is blazing a trail to all-IP mobile networks

Fast-growing Indian mobile operator Reliance Jio may offer a glimpse of where all mobile networks are going eventually, to packet-based Internet Protocol infrastructure.

At Mobile World Congress, the world’s largest gathering of the mobile industry, Reliance Jio stands out by having none of the specialized 2G and 3G infrastructure that long distinguished cellular carriers.

Almost all mobile operators still have circuit-switched network gear in addition to IP systems. It came along with the 2G and 3G networks the carriers used before adopting LTE. Most are likely to keep older networks running for years, though some are moving faster than others to clear the decks.
