Network

Just last year, HSPA functionality was only found on the very high-end mobile phones, such as Nokia N95. Anyway, in only a year, 3.5G connectivity has been the mainstream. New HSPA handsets has been launched to compete Nokia. A good example is the very small and light Sony-Ericssons K660 phone which is definitely targeted at the mass market.

Another problem with HSPA phone is the spectreum standard. When browsing the specs of the new Windows OS Experia X1 phone, we could notice that it will come in two hardware versions: one supporting HSPA in the 850/1700/1900/2100 MHz bands and another one in the 900/1700/1900/2100 bands. The first variant is probably targeted at the US and Australian market since they have networks in the 850 and 1900 MHz bands and that one odd HSPA network of T-Mobile in 1700 MHz. The 2100 MHz is for roaming. The second variant seems to address the European market where we might see UMTS migrating to the 900 MHz band soon beyond the first network in Finland using this frequency.

HSPA Phone: Quad band is not enuff :).
