Re: May indicate another problem said by BillRoland:All these carriers putting caps and restrictions on their 3G services may indicate another problem I've been predicting: neither EVDO nor HSPA can scale to cope with heavy demand. I see it all the time on Sprint EVDO Rev A here where I live, the laptop card slows to 56Kbps speeds at certain points of the day, despite the signal being strong. EVDO is 2 mbps per "system" or channel. Most areas only run 1 EVDO channel, all the others are for 2G Voice and Express Network/Vision/1x.
And that 2mbps is being shared among all the users on the tower (it might be actually 4 or 6 mbps for the whole tower because of sectoring). EVDO is really a trinket, gimick toy. Since day one it could NEVER be a replacement for the usage demands of Voice. Cellphone voice service runs at 9.6k/bbps, cutting edge speed in 1987  |
