Altair and Rohde & Schwarz showcase live LTE handover between TD and FDD

Telecom Lead Middle East: Altair
Semiconductor’s FourGee-3100/6200 chipset has completed TD/FDD
LTE live handover testing with Rohde & Schwarz, a manufacturer of
wireless communications and EMC test and measurement equipment.

The test employed Altair’s FourGee chipset in an end-user
device. It enabled communication between different LTE modes, achieving an
uninterrupted and continuous data session with low handover latency from a
20MHz TD-LTE channel and a 10MHz FDD channel and back.

By allowing the two LTE duplex modes to operate interchangeably on the same
device, as well as enabling global LTE roaming, this achievement has
significant market implications.

The ramifications of live LTE handover are major,
addressing one of the LTE industry’s most desired goals harmonization of all
standard variants. Our baseband portfolio, complemented by our multiband radio
chipsets, offer the market’s most flexible and global solution,”
said Eran Eshed, co-founder and VP of Marketing at
Altair Semiconductor.

Altair’s FourGee LTE chipset is one of the only
commercial solutions supporting both FDD LTE and TD-LTE. The chipset supports
all 3GPP Release 9 bands and is deployed for commercial use in numerous LTE
markets around the world.

We are pleased to work with Altair on this exciting
development and look forward to the upcoming demo,” said Michael Altmann, head
of Product Management Mobile Radio Testers of Rohde & Schwarz.

We are committed to providing world-class test solutions
for LTE and to help advance real solutions for this rapidly growing
market. This demonstration again proofs the capabilities and potential of
the R&S CMW500 platform,” Altmann added.
