    Hi all,
    Im about to buy new mobile phone, but the one im interested in unfortunately the wifi is only only b/g/n 2.4gh. Was wondering how is the speed in comparison.
    The reason I ask is because in europe nowadays we r using dual a/b/g/n, and with my laptop of b/g/n I had problem, even for opening email i was struggling, and I dont want to have the same problem with the mobile phone.
    Thanx

    802.11b: max raw data rate is 11Mbps, 2.4GHz only
    802.11g: max data rate is 54Mbps, 2.4GHz only
    802.11n; max data rate is 600Mbps, 2.4GHz/5GHz
    802.11ac: max data rate 1300Mbps, 2.4GHz/5GHz

    802.11n should (normally) be more than adequate for everything bar streaming of HD media content, but the 2.4GHz spectrum is increasingly crowded which causes interference and lowers throughput.

    The issue is almost certainly with the speed of the service supplying the Wi-Fi router. It is very unlikely that the Wi-Fi is throttling the speed available in Europe.

    Just to add some perspective, 'Mbps' denotes megabits per second as some occasionally confuse it to be 'MBps' or megabytes per second. A megabyte is 8 megabits so a 600 Mbps connection would be transferring 75 MB each second (600 divided by 8). Also, always make allowance for that 'max data rate' designation because the corresponding numbers are always based on ideal, lab test numbers. In real world conditions what's rated as 600Mbps will often be much lower, and vary quite a bit, a relatively consistent 400 to 500Mbps is more likely.

    As for the OP's issue with having problems even with email over WiFi, I'm guessing it was more of an isolated WiFi connectivity problem as opposed to whether the router itself was even an older 802.11b rated model. Email being a primarily text based transfer, it requires very little throughput. I'd guess the issue would be more related to being too far away from the router's effective WiFi coverage, or a matter of opening up emails with large attachments, or if it's a regular occurrence just a need to reconfigure the router. Disabling the autoloading of images and graphics can help too.

    Thanks all for ur reply.
    I just changed to orange in barcelona from movistar.

    On the description it is up to 300mbps (or 500 i forgot), & with the a/c dongle i get somewhere about 220mbps
    The router is actually not more than 3m away from my laptop.
    Here is what I got with my mobile
    [​IMG]

    When the technician install it, he just said that yeah u need to hv wifi card which support a/c/n & 5ghz
    With a/c wifi dongle, everything is solved.

    Now, the thing is, I dont want to hv to use my data package all the time in my flat when in fact I hv wifi connection, so I am a little bit worried to buy this b/g/n 2.4ghz phone

    Do you guys think I will hv problem connecting to wifi with my mobile (because of the mobile bgn) or it has something to do with the router setting?

    Thanx

    Speed also depends on number of antennas on your device and router, its known as MIMO. If you have device have only one 802.11n internal antenna, it speed will be limited max to 72Mbps, even if your router has 3 antennas and can handle up to 450mbps. Device with 2 antennas is 150Mbps capable. You should need to read your device specs to see labels tike 1T1R, 2T2R and so-on, which indicates antennas count for transmit and receive.

    The problem I have is, my apartment building was retrofitted with cable in the 90's and hasn't be updated since. I have the highest speed available and the download speed is still interminable. The provider said there is nothing they can do about it. Now I know why everyone here has a satellite dish on their balcony.

    You won't have a problem connecting as the standards are all backwards-compatible; you'll simply be limited to 802.11n data rates.
