Intertelecom Rev.A (CDMA) with Sierra Wireless AirCard 802S hotspot

Usage of modern smartphones (i.e. iPhone 5) with GPRS/EDGE technology in year 2013 is that kind of sophisticated torture. EDGE is in use by Kyivstar from 24.10.2005. There is still no 3G or 4G frequencies licensed to major Ukrainian GSM operators (Kyivstar, MTS, Life). So to keep Kyivstar number and get fast internet outdoor some external solution needed. One of those solutions is CDMA 3G Wi-Fi hotspot. Those devices could be connected to Intertelecom, PeopleNet, CDMA Ukraine. For EVDO Rev.A it is theoretically DL:3.1/UP:1.8 Mbit/s. A lot of CDMA operator dealers in Ukraine selling Sprint OverdrivePro 3G/4G mobile hotspot (assuming that device was previously locked for Sprint network).

Power on, connect to 3G takes about 40-60 second.

Wi-Fi Router for Kyivstar/Beeline Internet at home

Хорошую скорость L2TP и PPTP тунелей для подключения к Домашнему интернету от Киевстар (бывший Билайн который в свою очередь бывший Голден Телеком) дают маршрутизаторы с прошивкой http://code.google.com/p/wl500g/. список поддерживаемых устройств http://code.google.com/p/wl500g/wiki/Devices

скорость L2TP туннеля для маршрутизаторов с прошивкой 1.9.2.7-rtn-r3702:
ASUS WL-500g Premium V2 (240МГц/32МБ/8МБ) составляет примерно 30 Мбит/с
ASUS RT-N16 (480МГц/128МБ/32МБ) составляет примерно 90 Мбит/с (60 Мбит/с с оригинальной прошивкой от АСУС)

Думаю сейчас (Январь 2012) ASUS RT-N16 самый быстрый из бытовых маршрутизаторов (с ценой порядка 100$) для доступа в Интернет с использованием тунеллей. Другие маршрутизаторы в зависимости от мощности их процессора и качества прошивки могут очень сильно ограничивать скорость работы с Интернет. Так довольно мощный Linksys WRT610N v1 (300МГц/64МБ/8МБ) дает порядка 6-8 Мбит/с с прошивкой dd-wrt.
