Apple has missed a trick today according to Andreas Bernsrtrom, CEO of VoIP company Rebtel and guest columnist on ITProPortal.com (check his posts here).
Enabling full 4G, he says, would have enhanced the consumer experience of the latest iPhone tenfold. On 4G networks, smartphones could work similarly to regular (wireless) broadband routers.
Devices out there could actually cooperate for increased capacity, rather than compete with each other. Bernstrom adds, "we would have literally been able to jump back and forth from congested routes to less congested routes – it could have put an end to dropped calls due to over-capacity, slow loading times and poor VoIP service (Voice over IP) quality".
Apple stopped short of a full LTE roll out and instead went for HSDPA. The iPhone 4S is also Apple's first true world phone, combining GSM and CDMA on one chip and almost certainly using a Qualcomm IP/baseband chipset.
Apple has also confirmed that the iPhone 4S integrates two smart antennas that switch between send and receive to improve call quality. It is likely that Apple refrained from going 4G because they thought the cost would have outweighed the benefits.
