IDG Contributor Network: Smartphones are about to become network hubs
Here's the quandary with smartphones: despite featuring copious radios within, such as Bluetooth, Wi-Fi over both the 2.4 and 5 GHz bands, 4G LTE, Near Field Communication (NFC), and so on, the radios with the most propensity for delivering media don't work together.The two Wi-Fi bands found in today's smartphones generally aren't used at the same time. The issue has been related to needing two antennas connected at the same time for the different bands. It's because the frequencies used have very different characteristics.New routersThis dual-band limitation is about to change, for a couple of reasons.Firstly, the newest routers, or wireless access points, that are being sold are already kitted with the two radios and antennas configured to work together at the same time.
