DoCoMo Develops 8-Band Power Amp for Phones
NTT DoCoMo announced that it has developed a prototype multi-band power amplifier that has eight frequency bands between 700MHz and 2.5GHz. This amplifier will allow manufacturers to make phones that can contain different cellular radios, such as LTE, GSM and UMTS. Power amplifiers are what boosts cell phone's transmitting capabilities, allowing them to connect to cell towers. The new amplifier from DoCoMo is small enough that it can be used in mobile phones without increasing their size.
AT&T Throwing 5G Tech at the Wall to See What Sticks
AT&T today said it plans to test a wide variety of potential 5G technologies throughout the year as it evolves from 4G LTE to next-generation mobile broadband. For example, the company intends to kick off field trials of AirGig later this year.
Qualcomm Fine Tunes RF Antennas for Snapdragon 835
Qualcomm today introduced a new range of RF front-end products that will complement advanced processors such as the Snapdragon 835. The new family of radios are the first gallium arsenide (GaAs) power amplifier modules to come from Qualcomm.
Sprint Pins Network Strategy On 'HPUE' Technology
Sprint today detailed a new technology called High Performance User Equipment that promises to improve the behavior of its 2.5 GHz spectrum in terms of capacity, speed, and range. HPUE is a modem-level technology that ushers in a new power class for mobile phones, called Power Class 2.
AT&T Trudges Forward with 700MHz Interoperability
AT&T recently told the FCC where it stands with respect to interoperability in the 700MHz band and said it is making good progress. At issue is phones' abilities to roam between several different bands within the 700MHz A Block slice of airwaves, specifically Band 17 and Band 12.
With something like this, it will be easier for AT&T to switch to LTE when they decide to do so...
Now I don't have to.....
