    Hello.

    Last night, I was helping a client with his old iPhone 4S' personal
    hotspot as shown in http://support.apple.com/en-us/HT4517 web page. It
    uses Verizon Wireless 3G for his 4 GB data cellular connection. We got
    the wireless (WPA2) connection to work fine, but it was very slow like
    crappy dial-up modem speeds. Is this normal? iPhone's iOS v8.1.2's top
    screen says 1X (is this a speed number?) and left of MBP to be very
    close. Updated Mac OS X 10.8.5's top screen shows an infinite(?) symbol
    instead of that wifi arc symbol.

    Thank you in advance. :)

    radio transmission technology. it's roughly 15 years old.

    <http://www.phonescoop.com/glossary/term.php?gid=150>
    The first in a family of cdma2000 1x digital wireless standards
    designed to extend and replace the IS-95 CDMA standard. 1xRTT is
    sometimes referred to as a "2.5G" standard.
    ....
    The initial release - release 0 (zero) - supports data speeds peaking
    at 144 kbps. Typical real-world speeds are closer to 60-80 kbps.

    the reason he's seeing 1xrtt is because the area that person is in has
    not been upgraded to evdo.
    <http://www.phonescoop.com/glossary/term.php?gid=151>
    EVDO provides data rates over 10 times faster than 1xRTT, the
    previous data technology for CDMA networks. EVDO is not as fast as
    the newer LTE 4G standard.

    that area has *probably* been upgraded to lte, but the iphone 4s
    doesn't support lte so there's no way to know nor does it matter
    because it won't work on that phone.

    Would it be fair to state that 1xrtt was the first packet switched data
    service on CDMA ? Or was there one before it ?

    (GSM went from phone call switched data, then 2G with GPRS (packet
    switched), then EDGE (improvement on GPRS with more channels uses) and
    then 3G with HSPA and HSPA+ and 4G with LTE.

    Isn't EVDO also considered 2.5g in terms of actual speeds delivered ?
    (as I recall, only 3mbps max, right ?)


    In the case of GSM, and I would assume CDMA, low signal quality often
    causes handset to drop down to older tech/lower speeds. For instance,
    outside a subway station, you would easily get LTE, but as you drop
    down, it switches to 3G and sometimes down to 2G (GPRS or EDGE) before
    losing signal. Same with rural areas.

    (Note original GSM carriers will soon remove 2G support in order to
    refarm spectrum for LTE or 3G.) New carriers like Bell/Telus in Canada
    entered GSM at 3G so they never deployed 2G.


    Also: CDMA carriers in Canada have begun to shutdown their networks,
    first shutting down EVDO, forcing users back to 1xrtt. (again, to refarm
    spectrum since CDMA has not been marketed in Canada for some time but
    still used by GM OnStar and other apps).

    gprs was very slow. edge was comparable to 1xrtt long after 1xrtt came
    out.
    not the case with cdma.
    they're removing it already.
    cdma is going away, as is gsm.

    hspa will be around for a while until lte is more widely deployed.
