Wireless LAN

A wireless local area network (WLAN) is a wireless computer network that links two or more devices using a wireless distribution method (often spread-spectrum or OFDM radio) within a limited area such as a home, school, computer laboratory, or office building. This gives users the ability to move around within a local coverage area and still be connected to the network, and can provide a connection to the wider Internet. Most modern WLANs are based on IEEE 802.11 standards, marketed under the Wi-Fi brand name.

Wireless LANs have become popular in the home due to ease of installation and use, and in commercial complexes offering wireless access to their customers; often for free. New York City, for instance, has begun a pilot program to provide city workers in all five boroughs of the city with wireless Internet access.

History

Norman Abramson, a professor at the University of Hawaii, developed the world’s first wireless computer communication network, ALOHAnet (operational in 1971), using low-cost ham-like radios. The system included seven computers deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines.

WLAN (AM)

'WLANr'A337928427 (1390 AM, "Timeless Classics") is a radio station licensed to Lancaster, Pennsylvania, USA. The station is owned by iHeartMedia, Inc. and licensed to Clear Channel Broadcasting Licenses, Inc. It airs a Spanish tropical music format.

The station was assigned the WLAN call letters by the Federal Communications Commission.

The station was originally owned by The Altdoerffer Family of Lancaster County, Pennsylvania. Today WLAN & WLAN-FAM are owned by Clear Channel Communications.

In January 1948, the Federal Communications Commission authorized WLAN to change from 1 KW (daytime only) to 1 KW (full-time), concurrent with a change in frequency from 1320 kHz to 1390 kHz.

On January 4, 2010, WLAN changed its format from adult standards to classic hits. As of February 7, 2012, the station had switched to a conservative talk format, including Glenn Beck, Rush Limbaugh, and other national performers, plus Harrisburg's own RJ Harris & Bob During. Its programming relays WHP, Harrisburg. It was confirmed that as of May 4, 2015, the station once again changed its format but this time to Spanish Tropical music under the name of "Rumba 1390". The station now caters to the Lancaster Spanish population and will be fully automated (meaning it will have pre-recorded voice tracks and no live on-air personalities).
