Global engineers will gather next week in Geneva in an attempt to free up mobile spectrum by persuading governments to reallocate dormant frequencies they control for wireless broadband services. The International Telecommunication Union's World Radio Conference will try to reach an accord on
sharing the underused spectrum.
ZTE has reached a milestone in long-distance optical networking, delivering data at 400 Gbps over more than 3,000 miles without the use of repeaters. The test -- which puts ZTE in league with rivals such as Alcatel-Lucent, Ciena, Fujitsu and Huawei, who are moving forward with their own pioneering long-distance optical platforms -- relied on WDM technology and 25 reconfigurable optical add-drop multiplexers to deliver data over a single-mode fiber link.
The Federal Communications Commission on Wednesday proposed rules aimed at opening large swaths of bandwidth to unlicensed usage to relieve traffic jams on Wi-Fi networks in public and private places, such as airports, hotels and homes. In opening up frequencies in the 5 GHz band, regulators would pave the way for increasing download speeds to up to 1 gigabit per second. One potential hurdle: Governmental and private groups already occupy parts of the spectrum.
A proposal by satellite provider Globalstar to add a fourth Wi-Fi channel to its service package is generating a backlash from industry groups that say the plan amounts to an unfair and inefficient use of unlicensed spectrum. In comments to Globalstar's November filing with the Federal Communications Commission -- which were due Monday -- the Wi-Fi Alliance, the Bluetooth Special Interest Group and others in the industry argue that the company's plans may negatively affect performance by leaving less bandwidth for other users.
