802.11i secures wireless LANs

The new 802.11i improves on WEP by using completely new encryption algorithms and key-derivation techniques. This wireless security standard, finalized in 2004, makes it possible to safeguard over-the-air communications at Layer 2.

Another Article on Evil WAP Twins

Read full Story

In an evil twin attack, a malicious hacker steals users' signals by deploying a wireless base station that sends a stronger signal than the legitimate WAP. The "evil" base station masquerades as the real Wi-Fi network, inviting users to log on over bogus prompts so the attacker can access their data.

"This offering reinforces the solution approach that is increasingly required by organizations implementing wireless networks to achieve real-time access to vital data and information," said Scott Stone, CEO of Padcom, Inc.

ClearWire Blocking VOIP Calls

This is a concern I have had for some time. I currently have two VOIP lines in my home office. One from Vonage and one from Packet8 running over my Bellsouth Fast Access DSL line. Is it illegal for Bellsouth to block the ports that these VOIP services use? I am still using the local phone as my internet provider I have just move my voice service away from Bell.

Homeland Security & Infrastructure Protection

Experts at the CTIA show last week call for homeland security, wireless industry cooperation.

Five security experts, during a panel discussion at the CTIA (Cellular Telecommunications and Internet Association) Wireless 2005 conference, called for industry and government officials to cooperate on setting up effective warning systems for terrorist attacks and natural disasters and better wireless interoperability for emergency responders. Jim Dailey, director of the office of homeland security for the Federal Communications Commission (FCC), notes that police and fire officers responding to a disaster often have to carry several radios and a bullhorn to communicate effectively. Ron Sege, president of Tropos Networks, argued that metropolitan regions might benefit from wireless mesh network "hot zones." Shortly after the September 11, 2001, terrorist attacks, the wireless industry created Wireless Priority Service (WPS) to give emergency responders priority over other communications on a wireless network. Panelists also criticize E911 services; Ed Thomas, an FCC engineering chief, says he only got a recorded message when he tried to call 911 on his wireless phone.

Combo - EDGE/Wi-Fi access

As Joanie Wexler points out in her weekly newsletter Cingular has started a WiFi/Edge Service that should be attractive to busy mobile professionals who need to stay connected. I do not understand why Verizon Wireless has abandoned it's relationship with Wayport last year and drop any support for WiFi service option because they fell EVDO will trump the WiFi revolution. Not sure about that will shall see.

Today's focus: Cingular couples EDGE, Wi-Fi access

By Joanie Wexler
The hard part about choosing between cellular and Wi-Fi services is the tradeoff between speed and coverage. Wi-Fi is grand if users are able and willing to go to the location where the high-speed network is. Cellular works particularly well if users can tolerate sub-megabit speeds, because broadly deployed cellular networks basically come to wherever the user is.

That's why the idea of having devices with dual-mode radios and the intelligence to pick the fastest network available has been alluring. In this spirit, Cingular Wireless launched what is believed to be the first national unlimited EDGE/Wi-Fi data service plan at this week's Cellular Telecommunications Industry Association (CTIA) show in New Orleans.

The mobile network operator says its customers can now access data at either 4,000 Wi-Fi hot spots in the U.S. or via its Enhanced Data Rates for Global Evolution (EDGE) network domestically in 13,000 cities and towns. EDGE service is also accessible internationally in about two-dozen countries (nine of which are in Europe) via roaming agreements Cingular has struck with other carriers. Generalized Packet Radio Service (GPRS) service is available in about 80 countries where EDGE is not yet available, according to the company.

Cingular's Wi-Fi connections are provided through agreements with SBC, Wayport, Concourse Communications and StayOnline, and available on Cingular's own Wi-Fi networks in several airports and train stations. Dual-mode Wi-Fi and EDGE access is available for $99.98 ($79.99 for EDGE plus $19.99 for Wi-Fi). Customers purchasing a two-year contract with the unlimited plan qualify for a free EDGE PC modem card valued at about $249.99, Cingular says.

Note: For EDGE-only users who roam the globe, quad-band equipment that works in the U.S., Europe and other parts of the world is available: the Sony Ericsson GC83 and Sierra Wireless Airlink PC cards for laptops, as well as the quad-band Treo 650 handheld.

German Government Agency Launches Wireless VoIP Network

LightPointe, a designer and manufacturer of optical wireless products based on free-space optics (FSO) technology, today announced that the Landratsamt Main-Tauber-Kreis District Office in southwest Germany has deployed a VoIP network via multiple optical wireless connections.

The German government agency's wireless VoIP network includes five LightPointe optical wireless links that integrate the voice and data services for various satellite offices into the main district office. The mission-critical point-to-point network connections support key government functions, including health services, youth welfare, and forestry commission. The optical wireless network covers a one-kilometer radius near Stuttgart. Landratsamt Main-Tauber-Kreis District Office provides government services for more than 135,000 residents.

National broadband policy?

I agree with one of the FCC Commisioners, Michael Copps. In his recent online article he points out some very good reasons for forming a clear national broadband policy.

Big changes are reshaping the telecom industry. Giant mergers--SBC Communications acquiring AT&T, Verizon Communications swallowing MCI--raise huge questions about how consumers will be affected. More local-government efforts to create their own broadband networks are facing fierce resistance from the Baby Bells and cable companies such as Comcast.

Inmarsat Inmarsat satellite broadband service

The first of three Inmarsat I-4 satellites is scheduled to launch from Cape Canaveral, Florida, next Thursday, and will be the largest commercial satellite in the sky, company Chairman and Chief Executive Officer Andrew Sukawaty said in an interview Tuesday.

I-4 is the fourth-generation of Inmarsat satellites, and will be the backbone of the company's Broadband Global Area Network, offering at least 10 times the communications capacity of the current network. The new satellites will allow the company to offer data speeds of up to 432K bits per second for uses such as video-on demand, video conferencing, phone, e-mail, LAN, Internet and intranet services, it said.
