Monitoring network performance is key to accessing 5G enterprise market

Whilst the ITU and 3GPP may still be finalizing the 5G specifications and it is not yet clear there what the 5G network will actually look like, at least we know the 3 target use cases for 5G: enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC), and massive machine type communications (mMTC). For operators, monitoring network performance in real…

How temperature affects system design: the basics (part 1 of 3)

In system design, temperature is a crucial factor to be considered. It can affect signal integrity, user equipment, and ultimately user experience. Our systems have to work at -40°C (-40°F) for our customers in Canada and Russia as well as at +45°C (104°F) for our customers in Dubai. This wide temperature range of 85°C (144°F) is very demanding on any…
