[WISPA] Northrop to provide wireless public safety net for NYC
Northrop to provide wireless public safety net for NYC BY Bob Brewin Published on Sept. 12, 2006 New York City has awarded Northrop Grumman a $500 million contract to develop a broadband wireless network, which the city characterized as the “most aggressive commitment by any municipality to provide a next-generation public safety network.” The New York Citywide Mobile Wireless Network (CMWN) will provide the New York Police Department, Fire Department, Transportation Department, Office of Emergency Management and other agencies with a high-speed network capable of handling a variety of broadband data including federal and state anti-crime and anti-terrorism, fingerprint, mug shot and city map databases, and full-motion streaming video, the city said. Mayor Michael Bloomberg said the new network will help fill in the communications gaps that occurred as emergency workers grappled five years ago with the terrorist attacks against the World Trade Center. “One of the most important lessons learned from the Sept. 11 attacks was that our emergency responders need better access to information and clearer lines of communication in the field,” Bloomberg said. CMWN will ensure that public safety workers will have the tools they need to fight crime and help in emergencies, Bloomberg said. It will also improve efficiency and productivity in nonemergency situations by streamlining communications and improving service, he added. The city said it expects Northrop Grumman will turn the network on in Lower Manhattan by January 2007, with citywide deployment planned by spring 2008. The city has an option to extend the contract for 10 years. The company said it selected IPWireless to provide its Universal Mobile Telecommunications System equipment used by commercial cellular carriers for CMWN. The gear can provide mobile users with broadband data service at speeds up to 16M per second, according to a fact sheet on the company’s Web site. Lori Horton, director of strategic wireless initiatives at Northrop Grumman, said CMWN will provide users with data rates of 2M per second in a vehicle moving 60 miles per hour. The company demonstrated in a test earlier this year in Lower Manhattan that it can provide such data rates to vehicles moving at 120 mph, she added. A unique feature of the network will address concerns raised by top commanders’ inability to communicate in the aftermath of the terrorist attacks, Horton said. It will give priority to incident scene commanders so they get the bandwidth they need when they need it, she said. The city said the high data rates provided by CMWN will allow the NYPD and FDNY to deploy new applications to workers in the field. The network will enable police officers to access real-time photo, warrant and license plate databases. The network will enable FDNY to establish reliable wireless connectivity between the Fire Operations Center and responders in the field to transmit on-scene data and video, the city said. New York will work to provide network access to state and federal public safety agencies. The city said it plans to use CMWN support a number of nonemergency applications that will provide a significant improvement over existing technology for city workers in the field. For example, it will include remote water meter reading technology for the Environmental Protection Department, which will reduce costs associated with conventional methods of meter reading. The city said its DOT will use the network to expand its ability to remotely monitor and program traffic signal controls daily and during emergencies. When New York released the CMWN bid request in 2004, it attracted interest from bidders including EDS, IBM, Lucent and Lockheed Martin. --- --- -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/

[WISPA] FW: BellSouth to offer 50Mbps next year
Investor's Business Daily BellSouth To Give A Boost To Its Broadband Services Tuesday September 12, 7:00 pm ET Reinhardt Krause BellSouth plans to upgrade about 10% of the households it serves to 50 megabits per second Internet access starting in the second half of 2007 -- a service nearly 10 times faster than it now provides. The upgrade targets 1.35 million homes in subdivisions or housing complexes where BellSouth (NYSE:BLS - News) has already brought fiber-optic wiring to within 250 feet of homes. Most of the upgrade, mainly in suburban areas of the Southeast, will take place in 2008, BellSouth says. BellSouth plans to use a technology known as VDSL2. This is a faster version of digital subscriber line technology that phone companies use to deliver broadband Internet access. The VDSL2 upgrade will give BellSouth a major weapon as phone and cable TV companies battle for broadband customers, especially high-end subscribers willing to pay higher fees for the fastest speeds. The BellSouth upgrade will put its broadband speeds in the ballpark of where Verizon Communications (NYSE:VZ - News) is now in a few markets, and where some cable firms expect to be within 18 months. For now, BellSouth's top DSL speed is just 6 mbps, and most of its customers order 1.5 mbps or slower service. Aside from the 1.35 million homes that will get VDSL2, the rest of BellSouth's region has been earmarked for another DSL variant that will boost speeds to 20 mbps to 25 mbps. BellSouth and other telcos largely lost the high end of the consumer broadband market, Bruce Leichman, principal of LRG Research, said. That's a difficult segment to win back. But VDSL2 will position them well to compete going forward. BellSouth has yet to reveal specific plans for VDSL2, but company executives have informed state regulators of plans to provide VDSL2- based services. BellSouth executives confirmed the plans in an interview. We're looking at the third quarter of '07 before we do our first field upgrades, said Bill Smith, BellSouth's chief technology officer. We expect to be able to do 50 mbps easy -- and maybe as much as 80 mbps.BellSouth hasn't disclosed what the VDSL2 upgrade will cost. Cable TV firms, meanwhile, aim to deliver Internet speeds from 25 mbps to 50 mbps. Their fastest offerings now generally range from 8 mbps to 15 or 16 mbps. VDSL2 network gear is designed to work in areas where fiber-optic connections are relatively close to homes. In the 1.35 million homes that will be upgraded to 50 mbps service, BellSouth uses a network setup known as fiber to the curb, or FTTC. Verizon, which doesn't use VDSL2, now offers the fastest Internet access among phone companies. Verizon has deployed fiber directly to homes using a network setup called fiber-to-the-premise, or FTTP. It's faster in part because its fiber wiring goes right to the home. Where its FTTP network is available, Verizon sells Internet access at 5 mbps, 15 mbps and 30 mbps speeds. In a few areas, such as parts of New York, Verizon has boosted Internet access to 50 mbps. Verizon says its FTTP network will be available to 6 million homes by year's end. The BellSouth DSL variant it will use for non-VDSL2 households is called ADSL2+. With ADSL2 and VDSL2, BellSouth plans to offer video-on-demand and TV services via the Internet. BellSouth hasn't started to use ADSL2+ gear in its residential network. Smith says that in the labs BellSouth has ADSL2+ gear that delivers Internet access at 12 mbps. We think there'll be a place in our network for multiple flavors of DSL, Smith said. For the VDSL2 upgrade, BellSouth has been working with equipment maker Tellabs (NASDAQ:TLAB - News). Aside from the 1.35 million homes, VDSL2 may be used in some apartment complexes where it makes economic sense. The math has to work out, Smith said. ATT (NYSE:T - News) agreed to purchase BellSouth in late February. Regulators are expected to approve the deal by year's end. BellSouth's broadband plans are subject to change once ATT takes over. But Smith says BellSouth has spent years putting its DSL upgrade strategy in place. ATT has used a lower-cost approach than Verizon to upgrade its residential network. ATT's Project Lightspeed uses a fiber-to-the-node setup, in which fiber lines are within 3,000 feet of homes. ATT plans to offer cablelike TV and video-on-demand services to homes via the Lightspeed network. Some analysts believe ATT will change its plans to boost Internet speeds. Cowen Co. analyst Tom Watts expects ATT to move to either an FTTP setup like Verizon or an FTTC approach like BellSouth. We have no plans to do that, said ATT spokesman Michael Coe. Consumer demand for Internet speeds above 6 mbps isn't clear, ATT says. But analysts and other communication firms say consumers want fast Internet speeds for Internet video, music downloading and other high-end applications. -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe:
Re: [WISPA] MT power supplies
Yes, ethernet is shielded. The good stuff. It's like almost 1/2 inch cat5. The tower has pagers, lots of trango, few backhauls, canopy 900, and some more I believe. The only thing up with me is some trango, and they have no problem. I am pointing at a bad cable. Brian Harold Bledsoe wrote: The 800 to 1300mA consumption is at 3.3V.

RE: [WISPA] MiniPCI wireless card recommendation...
I would say that it depends on the application. The CM9 and the R52 use different generation of Atheros chipset. The main difference between the 2 chipsets is the newer chipset requires slightly less power to run and if you are running the card in 10MHz or 5MHz modes it will only listern to that 10MHz or 5MHz whilst the older CM9 chipset will still listen to the whole 20MHz. If you are looking to replace a 200mw 2.4 card then both the CM9 and the R52 may leave some of your clients with a weak signal so the Atheros based 200mw cards would be the way to go. If you arent looking to use 10MHz or 5mhz then the CM9 is still a great choice however there are a couple of other next generation Atheros based cards out there. Cheers, P.

The 6th gen cards however, can both transmit and listen at 5MHz, 10MHz, 20MHz and 40MHz. An example is that if a CM9 is set to 5GHz-5MHz with a cf of 5805 it will transmit from 5802.5MHz - 5807.5MHz but will listen on 5795MHz - 5815MHz which I would imagine could cause problems if you're also using any of the neighbouring 5MHz channels. This is my understanding and although I have read about this on various forums I have not tested the theory.

Paul, What do you mean when you say the CM9 listens on the whole 20 MHz when set to 5 MHz mode? Lonnie On 9/13/06, Paul Hendry [EMAIL PROTECTED] wrote: I would say that it depends on the application. The CM9 and the R52 use different generation of Atheros chipset. The main difference between the 2 chipsets is the newer chipset requires slightly less power to run and if you are running the card in 10MHz or 5MHz modes it will only listern to that 10MHz or 5MHz whilst the older CM9 chipset will still listen to the whole 20MHz. If you are looking to replace a 200mw 2.4 card then both the CM9 and the R52 may leave some of your clients with a weak signal so the Atheros based 200mw cards would be the way to go. If you aren't looking to use 10MHz or 5mhz then the CM9 is still a great choice however there are a couple of other next generation Atheros based cards out there. Cheers, P.

Re: [WISPA] tv white spaces update and a question for you guys
Marlon, I'm rather surprised that you would even mention 2.4GHz(wifi I assume) as a possible technology to use in these bands. Now that they have cellular technologies specifically designed for BWA purposes (Canopy and WIMAX are good examples) and given the possibility of a fresh start to using this spectrum, using an unarguably inferior technology for BWA like wifi just doesn't make sense. You end up with the craziness we have right now in the current bands. If testing data for equipment operation in that band is needed, you could probably obtain this information from a few companies off the top of my head like Qualcomm(Flash-OFDM), IPwireless(TD-CDMA) and Airspan(WIMAX and proprietary), that currently have experience w/ 700MHz. IMO if they ever release a 'WISP band'(which I would be surprised), they need to have a GPS synchronized transmission cycle as a requirement... Here's an idea, make WIMAX as the accepted technology for that spectrum. Then all you need is the WISP(s) in the area to coordinate transmission cycles to minimize interference potential. That leads to a whole other subject, if a 'wisp-band' were opened up, the WISP industry could potentially be a whole new ball-game...think companies(AOL, Speakeasy, Covad, etc) spending 10s of millions to go regional/nation-wide that you would otherwise potentially not have to compete against.

Mayor Michael Bloomberg said the new network will help fill in the communications gaps that occurred as emergency workers grappled five years ago with the terrorist attacks against the World Trade Center. “One of the most important lessons learned from the Sept. 11 attacks was that our emergency responders need better access to information and clearer lines of communication in the field,” Bloomberg said. CMWN will ensure that public safety workers will have the tools they need to fight crime and help in emergencies, Bloomberg said. It will also improve efficiency and productivity in nonemergency situations by streamlining communications and improving service, he added. The city said it expects Northrop Grumman will turn the network on in Lower Manhattan by January 2007, with citywide deployment planned by spring 2008. The city has an option to extend the contract for 10 years. The company said it selected IPWireless to provide its Universal Mobile Telecommunications System equipment used by commercial cellular carriers for CMWN. The gear can provide mobile users with broadband data service at speeds up to 16M per second, according to a fact sheet on the company’s Web site. Lori Horton, director of strategic wireless initiatives at Northrop Grumman, said CMWN will provide users with data rates of 2M per second in a vehicle moving 60 miles per hour. The company demonstrated in a test earlier this year in Lower Manhattan that it can provide such data rates to vehicles moving at 120 mph, she added. A unique feature of the network will address concerns raised by top commanders’ inability to communicate in the aftermath of the terrorist attacks, Horton said. It will give priority to incident scene commanders so they get the bandwidth they need when they need it, she said. The city said the high data rates provided by CMWN will allow the NYPD and FDNY to deploy new applications to workers in the field. The network will enable police officers to access real-time photo, warrant and license plate databases. The network will enable FDNY to establish reliable wireless connectivity between the Fire Operations Center and responders in the field to transmit on-scene data and video, the city said. New York will work to provide network access to state and federal public safety agencies. The city said it plans to use CMWN support a number of nonemergency applications that will provide a significant improvement over existing technology for city workers in the field. For example, it will include remote water meter reading technology for the Environmental Protection Department, which will reduce costs associated with conventional methods of meter reading. The city said its DOT will use the network to expand its ability to remotely monitor and program traffic signal controls daily and during emergencies. When New York released the CMWN bid request in 2004, it attracted interest from bidders including EDS, IBM, Lucent and Lockheed Martin. --- --- -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/ -- No virus found in this incoming message.

Re: [WISPA] wireless fiber deployment
Amen brother Tom! You have seen the light! The whole mesh node bottleneck problem goes away if you have $90 millimeter-wave radios acting as gigabit backhaul connections from node to node. That is just one billion dollar application of this technology. Don't think this is pie in the sky either. Millimeter-wave radios can be built using cheap CMOS technology instead of the current SiGe. It is like the difference between building out of rust instead of diamonds. Ken started talking up low-cost gigabit radios a while back and few listened then. I thought he had gotten hold of some bad drugs till I met the millimeter-wave manufacturers that Ken hooked me up with at the IWPC. I saw the light then. I thought the manufacturers saw the light too when I talked about the day of millions of cheap millimeter wave radio modules being used everywhere to provide multi-gigabit connectivity at low cost. Sadly they thought I had gotten hold of bad drugs I think. All but one guy from Intel. He has gone way underground now though. I signed a NDA with him so I cannot say much beyond this. Trust me though when I say that low-cost GigE radios can and will be built someday. I just hope it happens before we all fall behind the technology curve. Cable and DSL will be selling 10 megs for $20 per month in a year. Can you all compete? I certainly wish someone would wise up and start churning out those low-cost dumb millimeter-wave modules. Give us a low-cost mini-pci millimeter-wave radio module and we will change the world forever. Scriv Tom DeReggi wrote: I'm a big fan of the potential of GB fiber. But I disagree with your comment.

In these cases, Gbit wireless is a point to point link for the last mile. I think that's where the economies of the wireless fiber solution begin to appeal to them.

For those who can't afford the 3-6 months to organize getting their fiber pulled. Now the second you can Span over 3 mile reliably, which 70-80Ghz can do, it gets more exciting. But at $40 grand, thats a tough sale, in Tier1 markets. At $500 a month for fiber, thats a 6 year ROI on the GB wireless gear. The advantage of Pencil Beam GB products is that a lot of links can be simultaneously deployed in an area. Making it so expensive takes away the abilty to use the technology to its potential, and used for the rare backhaul link. GB wireless should be being used for mass deployment of PTP in Urban America.
