Cavendish Kinetics has an answer to the the widening gap between actual mobile data rates and theoretically achievable data rates.
GSM in the 90s achieved actual data rates close to the theoretical maxiimum but, ever since, the gap between actual and theoretical has widened.
'4G technology supports data rates of 80Mbps,' says Cavendish Kinetics, 'but in practice delivers only 1-8Mbps for many users.'
There are three main reasons for the gap between theoretical and actual performance levels, says Cavendish;
One is the cosmetic need to put antennas inside the casing of the phone though external antenna are known to be more effective.
Another reasn is the increasing number of features in phones and increasing number of frequencies supported which require more components and antennas.
And the third reason is the increasing size of displays which creates a ground plane that blocks the antenna signal and limits performance.
"4G/LTE is not achieving the theoretical data bandwidth, and antenna frequency tuning can help achieve that," Dennis Yost, CEO of Cavendish Kinetics told the Globalpress Summit in Santa Cruz this week, adding "and only Cavendish MEMS technology can do it."
The Cavendish antenna frequency tuning MEMS device will be in moble devices this year, said Yost.
Another benefit of the Cavendish part is that it means you can take stuff out - it actually reduces the BOM by $1.
Cavendish developed its own MEMs design and process technology, said Yost.
