I've got a Samsung Blackjack with Cingular HSDPA. On the phone itself or via USB, I can pull 700kbit/sec down on a bandwidth test.
Yet over Bluetooth network access profile, I can only get around 300kbit/sec. Both devices are Bluetooth 2.0+EDR, and I'm using the Widcomm Bluetooth stack that came with the laptop. The network devices claims a connection at 700kbit/sec, and the theoretical maximum of 2.0+EDR is 2.1MBit/sec IIRC.
Are you talking about the IP and TCP checksums, or the Ethernet CRC? I just checked the RTL8139B and RTL8139C (you know, the most common Realtek chips out there), and they don't have anything except basic Ethernet framing (including CRC).
the rtl8139 may have been the most common realtek chip at one point, but the rtl8169 gigabit chip has these features.
the broadcom netlink gigabit pci express I've had on my two Core Duo laptops and on my Pentium M system has these features.
Where's the comparison between different onboard gigabit chipsets? (eg Broadcom, nForce, etc.) Where's the comparison between different PCI, PCI-X, and PCI Expressgigabit NICs?
If applicable, what are the settings for the onboard NICs being tested? Many have options for various CPU offload settings and optimizations for throughput or CPU usage.
Until we see these, how can we be sure if a high-end regular PCI-e NIC won't work just as well?
Higher density of users per site, continuous transmission instead of time division (ever held a GSM phone near a speaker?) and in my experience CDMA performs better in marginal signal areas then GSM does
Factors that favor GSM: - GSM's EFR and AMR-FR sound better than many codecs used on CDMA - GSM's timeslot nature means it has much, much better battery life than CDMA
Others: - Network performance varies based on base station and handset equipment as well as network configuration - Lower density per site could potentially encourage networks to build more towers, increasing overall coverage.
TDMA-based GSM is obsolete and being replaced by UMTS, which uses WCDMA (Wideband CDMA). UMTS has a much better codec (AMR-WB) than either CDMA or GSM, yet uses the existing GSM network core/SIM cards. With HSDPA, it provides network speeds comparable to EV-DO without requiring separate voice and data channels (like EV-DO).
Well, most of these plans that have daily charges that come with some extra benefit (unlimited night/weekends and/or mobile to mobile), and some of the providers that implement them give you a choice (cingular and alltel U do). These plans will probably work out to be cheaper for some people's usage patterns. I find the alltel U plan particularly attractive, for a prepaid plan.
They exist. After you spend $100 on T-Mobile USA Prepaid, minutes expire after one year regardless of your refill price. So, the first year will cost $100 ($8.33/mo) and you'll get 1000 minutes total for the year. If you need more, they'll last for a year. For $20 you'll only get 35 minutes, but for $100 you'll get another 1000 minutes. But after that first year, if you hardly ever used your phone, you could get away with $1.67/mo.
Do you really get screwed? Only if you are attached to your cellphone, have bad credit, and can't find a decent prepaid plan (which might be difficult in some markets).
For those that use their cellphone sparingly, you'd be hard pressed to get a cellphone plan with contract for under $20-30 + tax per month without something like an employee/dealer discount. However, there are numerous prepaid phones that cost a minimum of $10 per month or less to keep the account active. Virgin Mobile's per-minute plan, for example, requires you to deposit $20 every 90 days, for $6.67/mo. Then, it's $0.18 per minute.
T-Mobile's prepaid rate varies based on how much you buy -- anywhere from $0.33 to $0.10/min.
Alltel's U Prepaid per-minute plan is always $0.15/min.
Plans like these are great if your usage is low. Beyond 100-300 minutes per month, it's time to consider a real plan or a flexible prepaid plan. Alltel's U Prepaid has a plan that charges $0.75/day regardless of usage, but allows you to pick 2 out of 4 of these: unlimited nights and weekends, unlimited favorite calling number, unlimited text messaigng, and unlimited mobile to mobile. (Or, you can pick three at $1/day or four at $1.25/day). Then, other calls are always $0.10/min.
For $22.50/mo, you can get unlimited nights and weekends and then daytime calls at $0.10/min. Not a bad deal if you call mainly one person, talk at night/on the weekends, or call other Alltel customers.
A clever person with that Alltel prepaid service could sign up for an unlimited VoIP account for under $30, set that VoIP account number as their favorite number, and effectively get themselves unlimited cellular calls (assuming said VoIP provider allows open access via SIP and "three-way calling".)
Cingular has different prepaid plans. Some of them charge "daily access" or have a monthly charge, but they also have traditional per-minute plans like most prepaid services. If you don't like the plan you're on, Cingular gives you the choice to get another one without having to switch providers.
Verizon is the evil one; they've got one prepaid plan that has a daily access fee no matter what you do.
Well, the Xbox 360 was out for the entire month of November and widely available. The Wii and PS3 were available for part of the month and were in high demand...
With the negative opinions of the PS3 and the increase in HDTV uptake, it's not too entirely surprising.
No Bluetooth hardware driver supplied or can be found
As long as it's standard hardware, you should be able to get your Bluetooth adapter identified by adding the hardware ID for it to Windows's bth.inf, or by simply trying to load another driver via Device Manager. My HP Compaq nc6400 (Core Duo)'s module is a Broadcom module, although it was identified by Vista. Did you check Windows Update for a driver?
Audio is not all there: the "soft jacks" are not recognised, so plugging in headphones does not cut out the speaker!
Windows includes rudimentary HD Audio drivers that work (poorly) with most HD Audio devices; you'll want drivers from the audio chipset manufacturer (ADI, Realtek, etc.). You can use the XP drivers from HP, if you need to; chances are, they'll work better.
I disagree. HDTV over the air is a cleaner, sharper picture than the same HD channel received via cable, for far less money. And if the money ever gets tight, I can cancel the cable subscription and not have an expensive monitor sitting in the living room.
Well, it could be, if your cable company implements rate shaping. Some systems do not and simply pass on the same bistream you'd receieve over the air, although I understand that most companies do strip out the programming guide information you'd see OTA (or perhaps it can't be transmitted for some technical reason over clear QAM).
Here in the USA, most (all?) cable providers that provide HD locals provide them in the clear, and any tuner that supports QAM can decode them (many new TVs, probably the TiVo Series 3, some PCI/USB tuners). There's no need for paying for digital cable if you want the locals in high definition and have the proper equipment.
Of course, digital cable will get you more HD channels.
I have noticed an increase in ads in HD in the past month or so. At one point it was common to see a few during an hour of prime time programming; now I see a few every break. I used to be able to know when to hit play on the DVR when the picture filled up the entire screen again. I specifically remember Chase, American Express, and Best Buy commercials in HD.
FOX network promos are usually in HD here, as are the FOX affiliate's newscasts.
Not using Aqua eliminates OS X's graphics drivers. After that, much of the hardware in a Mac is generic (graphics card, wireless networking, usb/firewire, bluetooth) or usually well implemented (sound, ethernet) in Linux.
A few years ago I compared OS X 10.2 and KDE 3 (YDL) on a G3 All in One, with perhaps a Rage 128 or some other ATI GPU with 2 or 4 MB of VRAM.
With 256 and later 320MB RAM, KDE was much, much faster, by a long shot. It was a shock, since I'd long held the misconception that KDE/Gnome were slow (coming from the days of running Windows 95/NT vs. Gnome/KDE on old Pentiums with 64 MB of RAM).
OS X did not support that machine's video card for any sort of acceleration, and there was no way to turn down the needless eye candy to a level that made the OS usable.
OS X on that machine was slower than Windows 2000 with 48 MB of RAM.
This seems like an exercise in pointlessness. If you're going to run X11, why not just run Linux? It's more than likely a bit faster (especially in low RAM situations), and there is more X11 software available.
It specifically sets a private flag. The number is still sent over the telephone network, but the origination switch shouldn't (and usually doesn't) send the number to the customer.
At least one system I have used would transmit Private to the customer's equipment yet still display the calling party's number on the bill.
Please stop acting like everything revolves around the US. As far as I know your providers are the only assholes in the whole world that cripple their phones to such extent that you can't even connect to your mobile phone to download some pictures off it.
Verizon is the main carrier that does this. The largest carrier in the USA does not.
I just connect it to my laptop via my INCLUDED USB cable and software or use a bluetooth connection and can get anything on or off the phone in no time.
As can anyone with one of the GSM providers in the USA.
And the article is nothing but PLAIN AND SIMPLE FUD, I have an older S60 Series 2 phone and love it.
And because you use an older device which the article doesn't talk about, you're clearly qualified to discount the entire article...
And it doesn't drop calls or anything similar. Your problems must be related to the crap CDMA 2000 technology your providers most likely still use.
No, the problems are most likely related to a broken network.
There are millions of satisfied CMDA2000 users. CDMA2000 has benefits over any TDMA-based GSM technology and advantages compared to UMTS/WCDMA, such as lower latency data than GPRS/EDGE on non-3G networks (1xRTT), an easy upgrade path beyond "2.5G" (with 1xEV-DO), 1.25MHz channel width on all revisions, fast data with EV-DO Rev A -- 3.1MBit/sec down, 1.8MBit/sec up -- compare to 1.8/384 (or 3.6/384 on a subset of devices) on HSDPA.

Going GSM means that the phone that you get isn't useless if the prepaid account gets terminated or you want to switch to postpaid.
It also means that you can buy your phone off eBay (if you'd like something fancy).

Power Mac G3 is clearly listed. This would include the Power Mac G3 All-in-One.
