So much for wimax being light years ahead

Go Verizon!

it will roll-out femtocells -- with Wi-Fi on board, too -- to boost in-building coverage. The combination of LTE, with femotcells and Wi-Fi will enable Verizon Wireless to deliver broadband to a wide range of devices 😁

I still feel that Sprint being the lone supporter of WiMax is a mistake on Sprints part. Sprint had make a few of those in the past haven't they 🤣

Nice to know LTE is on the horizon 😁

Sure. I remember when Sprint was dead set on implementin EV-DV rather than EV-DO technology. They lost a bit of market share to Verizon before deciding that even though EV-DV would be better theoretically...it was not worth the wait. But...now the script is flipped. VZW cannot afford to fall behind Sprint and Wi-Max so it is either get this LTE up and running as soon as possible or adopt Wi-Max. I remember when VZW first launched EV-DO in San Diego and Washington D.C. and everyone else said "So what?" That's where Clearwire is now. Sure Wi-Max is not widely available, but it is out there which is more than we can say about LTE now. This move is not unexpected. I would say it is about time...

This is more a decision to finally be in sync with 1 of it's parent company Vodafone. Vodafone has been pushing Verizon Wireless to move to GSM and now it's the perfect time, when you have to build a new infrastructure.

I don't know why they need stupid femtocell, because 700nhz penetrates bldgs much better than cutrent frequencies.

It may penetrate better, but that doesn't help the people in areas that have poor coverage outdoors. And it's only a difference of ~150 MHz between 700 and Cellular, compared to the ~1 GHz difference between Cellular and PCS. The 700 signal won't be the far reaching, all encompassing blessing a lot of people think it will, though it will certainly help out some current marginal coverage areas.

Besides, depending on the plans VZW has for their femtocells, I might be inclined to drop my plan down as low as I can go because I could get unlimited minutes on the femtocell for much cheaper.

You do bring up a good point about the signal penetration. From what I read about the 800 band, the powe...

because not everyone gets great coverage in their home like you and I do. its an optional purchase, if you arent happy with your reception in home you can get a femtocell. whats the issue?

Signal issues are not simply penetration issues. Some people are just to far from a tower, femtocell will work so long as you are within 25 miles of a cell tower. Other people live in a valley. And others just live in areas that are too saturated and they get perfect signal there is just no capacity for them. 700mhz does have better penetrating power but it is still not enough in some cases. And last but not least. Verizon does not own a 700 mhz license in every part of there coverage area.

The open 700 MHz C Block VZW won spans the entire continental US and Hawaii. That's pretty much their entire coverage area.

It's true. They and Google bid on the upper 700 C block. I need to be specific, as AT&T has the lower 700 C block, which is not part of the open access. Also, the upper 700 C Block is regional, and Verizon acquired all 6 on the mainland (similar to what T-Mobile did with the AWS D, E, & F blocks, but they also went for Alaska & Puerto Rico as well) & Hawaii. They however avoided Alaska & Puerto Rico for some reason. So no licenses of any type up & down there.

Another thing, the upper 700 C block is built out by population of each EA (or upper 700 B block), and not geographical area, like the upper 700 A & B blocks are. So ...

To answer your question yes and no.

A cell phone has a maximum range of 8 miles from a cdma tower. The reason is that in accordance with fcc law they can only emit so much power threw there radio. Femtocell is different the amount of power it can emit threw its radio is drastically higher since it is a fixed radio there for then range of femtocell is 25 miles.

The real truth is femtocell does not need a tower to work. However, femtocell needs a tower for location based services in order to be e911 compliant.

Single timeslot GSM is limited to 35 km (~22 mi) range. Beyond that distance, speed of light propagation is not fast enough for the mobile to base signal to arrive at the base w/in the assigned single timeslot.

This is one reason why CDMA1x is superior to GSM for deployment in vast, open rural areas.

Call me naive and I am new to understanding Wireless phone technology but it does make sense that why Verizon has been pushing FIOS deployment every where in the US. So they can support this technology LTE and Femtocell on all markets. From what I have been reading pn this link. And me as a subscriber/consumer I have heard on several occasions from Verizon and Verizon Wireless that there intentions is to bring the to companies closer together or into one business offering several services. Plus if you have FIOS like I do it is just damn good!!!!!! 😁

The previous post contains much inaccurate info.

CDMA mobiles can have much greater range than eight miles from the nearest cell site. Living & traveling west of the Mississippi, I frequently use CDMA1x 850 & CDMA1x 1900 cell sites at ranges greatly surpassing eight miles.

Range is limited only by the PN timing window set at the cell site and path loss on both the forward link & reverse link. True, reverse link max amplifier power is 200 mW (+23 dBm) for most CDMA handheld mobiles. Even w/ a unity gain (0 dBi) antenna, 200 mW is more than sufficient power to exceed eight miles over open terrain.

Additionally, 200 mW is by no means an FCC restriction. For Cellular 850 MHz & PCS 1900 MHz mobile ERP, actual FCC regulations permit 7...

Finally, a femtocell typically has a max power output similar to that of a handheld mobile and a range of just a few hundred feet, certainly not 25 miles. For example, the Sprint AIRAVE has max power output of only 50 mW (+17 dBm).

I think you missed what i was saying. the femtocell unit has to be within 25 miles of a tower to work. the femtocell unit has a range its self of roughly that of wifi.

No. You could be talking about a repeater. A repeater requires at least minimal native signal in order to amplify it. But a femtocell w/ IP backhaul does not, at least not necessarily.

The Sprint AIRAVE, for example, can operate anywhere that SPCS holds PCS 1900 MHz spectrum (i.e. the contiguous US, AK, HI, and PR), be that inside or well outside SPCS native footprint. The AIRAVE uses GPS to determine its current location. Using that location data, the AIRAVE deduces its current geographic market (MTA or BTA). From that geographic market, the AIRAVE confirms its current SPCS license(s) (PCS A, B, C, D, E, F). And, w/ ...

From a technical perspective you are correct. From a legal perspective you are wrong.

The FCC mandates that all wireless services support location based services for e911 compliance. In order for femtocell to work the unit has to be within 25 miles of a cell site. Not to access the wireless network but to gain e911 information. That is how the femtocell service was designed.

The AIRAVE uses GPS for e911 compliance.

From the AIRAVE FAQ:

Why does the AIRAVE require Global Positioning System (GPS) technology?
Sprint AIRAVE uses GPS for network synchronization and device location
information required for 911.

And will you address why you erroneously stated that CDMA mobiles have...

Femtocell is a voice only technology; this is why they are adding wifi. So when you are in a building you can use femtocell for voice calls and wifi for data calls. It really has nothing to do with lte. It is a wise business move, but 2 unrelated items.
