The Wireless Fidelity (Wi-Fi) Alliance and AT4 Wireless have
signed a Memorandum of Understanding (MoU) to facilitate the testing of
unlicensed Long-Term Evolution co-existence on Wi-Fi, reports ITRealms.
Confirming this, the Marketing Manager, AT4 wireless, Belen
Garcia, told ITRealms that with the MoU, they would provide testing services to
assess fair co-existence of Wi-Fi and LTE in unlicensed spectrum (LTE-U)
devices in accordance with the Wi-Fi Alliance Coexistence Test Plan.
“The testing assesses whether commercially available LTE-U
devices co-exist fairly with Wi-Fi in the same environment,” Garcia said.
The development and deployment of LTE-U devices which
utilize 4G LTE radio communications technology in unlicensed spectrum, Garcia said,
introduces the possibility of interference with Wi-Fi equipment operating in
the same bands.
Small deviations in LTE-U design requirements, AT4 Wireless
official said, may affect Wi-Fi performance when working in proximity and in
the same frequency band, stressing AT4 wireless will conduct independent
testing based on objective tests and an industry-approved methodology to verify
that LTE-U products do not violate fairness indicators.
Wi-Fi Alliance, Garcia said, agreed to qualify AT4 wireless
to provide testing services based on the Coexistence Test Plan, which is being
developed by members of the Wi-Fi and LTE-U communities in Wi-Fi Alliance.
ITRealms gathered that the Performance Test Tool from AT4
wireless will collect the most relevant key performance indicators (KPIs), such
as throughput, latency (one-way delay), and jitter (latency variation).
“Official testing will commence once Wi-Fi Alliance releases
the final Coexistence Test Plan,” Garcia said.
The Managing Director at AT4 wireless, who doubles as the
Market and Sales Vice President at DEKRA Product Testing and Certification SU, Fernando
E. Hardasmal, said they are very proud to partner with Wi-Fi Alliance in radio
coexistence testing in this case with LTE unlicensed devices.
“AT4 wireless a DEKRA company now, considers radio
coexistence a very important issue that needs to be addressed properly given
the growing number of radio technologies that can work in multiple environments
including homes, cars, hospitals, cities, etc. The AT4 wireless services scope
now includes radio coexistence and at the same time our test tools are evolving
to address these new challenges. DEKRA is committed to be the Global Partner
for a Safe World and coexistence can be very relevant to Safety”, Fernando E.
Hardasmal.
For the president and CEO of Wi-Fi Alliance, Edgar Figueroa,
the test is critical that LTE devices operating in unlicensed spectrum exhibit
fair coexistence behavior with billions of Wi-Fi products in use around the
world.
“Wi-Fi Alliance is leading a multi-industry effort to ensure
LTE-U’s fair coexistence with Wi-Fi through testing. Establishing independent test organizations
to execute the coexistence test regimen is an important part of our effort,”
Figueroa said.
