Nokia’s wireless charging a real convenience

By

How can I ever go back to a plug in charger? It is just so convenient to plonk my smartphone down on the bedside table or my desk.

Wireless charging is not new – it is called the Qi global standard and many of you will have experienced it with a Braun toothbrush or Panasonic shaver. Apple, HTC, Google Nexus, LG and Samsung have some Qi options.

At present there are about 100 Qi products available. They comprise 1) the charge transmitter and 2) a charge receiver (either as an accessory or built into the device to be charged).

The best thing about wireless is well, no wires. It’s the brainchild of Nicola Tesla who demonstrated wireless transmission of electricity in the early 1900s.

Just set the device down on the transmitter and it charges. This means “snacking” charging and less chance of running low.

In Nokia’s case the 820 requires a charge jacket (RP $40), the 920 (and we presume the 925/928) has the receiver built in.

There is a charge plate (RRP $70) and a Fatboy pillow version (RRP $99.25)

  But wait there is more.

In collaboration with JBL/harman Nokia has incorporated Near Field Communications (NFC) with wireless charging (a flat rubberised top) and come up with a great looking and sounding ‘Powerup wireless charging speaker’. The speaker is rated at 100 watts and has its own digital signal processor (DSP) and 2.5” full range drivers, Bluetooth, 3.5mm audio in, and NFC (for playing music from NFC equipped phones). RRP is around $350 but on-line savings of 15% are common (don’t forget to factor in freight).

Also in collaboration with JBL is the NFC, Bluetooth and 3.5 audio in (no wireless charging) ‘PlayUp’ portable speaker. The speaker has a 10 hour battery but can be used with a micro USB charging cable. It is rated at 3 watts (maximum sound output 89 dB), has its own DSP and has a 360 degree sound dispersal system and emulates a mini sub-woofer so it is not bad for a small speaker. RRP is under $200.

 

 

And coming in collaboration with Monster is the Nokia Purity Pro NFC/Bluetooth headset. With the practical distance of NFC being only a few millimetres we are not sure how practical this method of sound transmission is but Bluetooth covers that admirably. The battery is rated for 24 hours use, it uses a micro USBcharger and frequency response is 20-20000Hz.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
