GSM vendors eying 450 MHz By Kevin Fitchard Oct 11, 2005 1:46 PM Challenging CDMA’s growing popularity in the 450 MHz bands in Europe, Ericsson and Nokia said today they would produce GSM infrastructure and handsets on the former analog radio frequencies. Ericsson said it intends to expand its GSM portfolio into the 450 MHz bands and plans to have commercial products ready to support rollouts in 2006. “We believe that GSM will be the leading access technology supporting mass market services for a long time to come,” Ericsson GSM head Ulf Ewaldsson said in a statement. “GSM 450 is the next logical step in providing service to emerging growth markets.” The move represents a change in trajectory for the world’s largest infrastructure provider, which has been mapping out its strategy in the 450 MHz bands with CDMA, but Ericsson shuttered its CDMA headquarters in San Diego earlier this year, and while it said it would remain in the business, it would scale back its global CDMA operations drastically. Nokia’s plans for 450 MHz were much more vague. Today it issued a statement saying it would support GSM at those frequencies and “underlined” its interest in the technology. But it didn’t commit to any timeline for developing radio access equipment or handsets for those bands. The 450 MHz bands were used for trunk radio services throughout Europe before the advent of the digital cellular revolution led by GSM. Spectrum holders, however, have been re-examining those bands as spectrum becomes scarce, and governments in both Europe and other regions of the world have been allotting new licenses in those high-propagation frequencies. Most new launches, however, have used CDMA technology due to CDMA’s smaller channel size, but alternate access providers like Flarion and IPWireless have developed products targeting the spectrum. Nokia to support GSM technology on 450 MHz frequency band for mobile phones Espoo, Finland - Nokia today underlined its interest in GSM technology on the 450 MHz frequency band. Nokia believes that a GSM450 frequency is a viable solution in providing affordable handsets and mobile voice-centered services to new growth areas with a low teledensity. For regions licensing a 450 MHz frequency band, GSM technology can provide a cost conscious alternative and thus enable mobile communications for a broad consumer base in very price sensitive markets. "Nokia believes that reducing the total cost of ownership for both affordable handsets and mobile voice services are the key when it comes to reaching the next billion consumers in new growth markets," says Søren Petersen, Senior Vice President, Nokia Mobile Phones. "The GSM450 frequency can provide a way of giving consumers and operators a choice in taking full advantage of the affordability of GSM technology." Nokia previously stated it expects the mobile subscriber base to reach three billion by 2010. This growth will be significantly fueled by markets which currently have a low mobile penetration rate. With the right combination of mobile phones, network solutions, services and a regulated environment, Nokia envisions a mobile landscape where operators can profitably offer mobile services to a broader range of consumers for as little as USD 5 per month. Nokia GSM handsets, such as the recently introduced Nokia 2652 and the Nokia 1600 (for GSM 900/1800/1900), are very popular in entry markets. Potentially Nokia products could bring the benefits of GSM technology to markets that are planning to license the 450MHz frequency band,

Wow. If 850 is great for indoor coverage imagine what 450 could do. Makes me wish the FCC would allow 450 for use here, but that would be impossible. That band is used by emergency services (Fire, police, rescue) if I remember correctly.

According to this spectrum chart it's setup for landmobile to satellites with a small amt. being Govt exclusive. It seems like too much is used for business and they would have a hard time getting them to give it up, depending on how much is actually used by certain industries. http://electronics.howstuffworks.com.../spectrum.html here is another chart on what frequencies are for what: 450 - 460 MHz: FM @ 25 kHz steps (450-455 base, 455-460 mobile) 450.050 - 450.925 Auxiliary Broadcasting 451.025 - 452.025 Industry 452.050 - 452.500 Taxi / Industry / Transport 452.525 - 452.600 Automobile Emergency 452.625 - 452.950 Transportation - Trucks / Railroad 452.975 - 453.000 Relay Press 453.025 - 453.975 Local Govt / Public Safety 454.025 - 454.650 Mobile Telephone 454.675 - 454.975 Mobile Telephone Air (ground) 455.050 - 455.925 Auxiliary Broadcasting 456.025 - 457.025 Industry 457.050 - 457.500 Taxi / Industry / Transport 457.525 - 457.600 {Maritime - shipboard repeater (mobiles @ 467.xxx) {Business - low power 457.625 - 457.950 Transportation - Trucks / Railroad 457.975 - 458.000 Relay Press 458.025 - 458.975 Public Safety / Local Govt 459.025 - 459.650 Mobile Telephone 459.675 - 459.975 Mobile Telephone Air (airborne) 460 - 470 MHz: FM @ 25 kHz steps (460-465 base, 465-470 mobile) 460.025 - 460.550 Police / Public Safety 460.575 - 460.625 Fire 460.650 - 460.875 Business - Airport use 460.900 - 461.000 Business - Central Alarms 461.025 - 462.175 Business 462.200 - 462.525 Manufacturers / Industry 462.550 - 462.725 GMRS (12.5 kHz steps) 462.750 - 462.925 Business (paging) 462.950 - 463.175 MED (Ambulance/Hospital) 463.200 - 465.000 Business 465.025 - 465.550 Police / Public Safety 465.575 - 465.625 Fire 465.650 - 465.875 Business - Airport use 465.900 - 466.000 Business - Central Alarms 466.025 - 467.175 Business 467.200 - 467.525 Manufacturers / Industry 467.550 - 467.725 GMRS (25 kHz steps) 467.750 - 467.925 {Business (2w, telemetry) 467.750 - 467.825 {Maritime - shipboard (rptr at 457.xxx) 467.950 - 468.175 MED (Ambulance/Hospital) 468.200 - 469.975 Business

The standard 450Mhz cell phone band comprises the following: 450.4 - 457.6 MHz uplink 460.4 - 467.6 MHz downlink That's 15Mhz they can work with.

The FCC always wants to make sure the bands used in the other side of the world are INCOMPATIBLE with the bands used here. So I wouldn't count on seeing 450Mhz here.

This is good as an analog Bag Phone Replacement since it reaches farther out (i think more than twice the Distance) than the Current 850 MHz Analog without the use of a Bag Phone. This is good for the Rural Areas and as what some article say will save Carriers Money on Cell Sites.

This is another point to show where people need to speak up to the FCC & say we don't want to take it any more as well as the manufactures.

LOL!...Just think of how many millions $$$ the manufacturers and customers would save if the FCC ideals weren't so ridiculous.
