LTE deployment continues: All the world is not 5G | EDN

A good read on 5G

LTE deployment continues: All the world is not 5G

-July 13, 2017

Hardly a day goes by that I don't hear hype relating to 5G. Indeed, the theme of this year's IEEE Microwave Symposium was "5G: Catch the wave" and 5G summits seem to take place monthly. Much of the 5G technology and technical standards are still in development, but that doesn't mean that wireless carriers are sitting around waiting for it. There's plenty of activity on the 4G/LTE front. Carriers are still bringing flavors of LTE online and the test industry is responding.

Although LTE deployment began in 2011, it's far from complete. LTE-Advanced and now LTE-Advanced Pro are maximizing speed and connectivity in LTE networks.

Recently, I've run across new products aimed at testing LTE and have even been personally disrupted when my wireless carrier changed its U1900 band from 4G to LTE. The result: my data rates dropped to 2G speed (about 80 kb/s), forcing me to upgrade my iPhone 4S. Fortunately, my carrier gave me 50% off the cost of an iPhone SE. The 4G-to-LTE transition is part of T-Mobile's $51-billion upgrade to keep the carrier competitive.

On July 3, GL Communications—a manufacturer of wired and wireless telecom testers—announced that it had upgraded its software for the company's LTE tester to test the LTE X2-AP application interface (Figure 1). The X2 interface handles communications between adjacent eNodeBs. The X2-AP interface is used for handing calls from one eNodeB to another.

This week, Anritsu announced new hardware and software for its MD8475B base-station simulator (Figure 2). Aimed at the physical layer, this instrument tests 4x4 MIMO with 256QAM high-order modulation and four-component carrier aggregation.

Because the so-called Internet of Things (more hype) is coming, engineers, developers, and even makers are adding wireless modules that bring connectivity to many devices. To serve that market, Telit in June made two announcements for LTE modules.

On June 3, the company announced the LE910-NA1, which the company says is certified by T-Mobile to operate on its LTE network. The module adds low-speed (64 kbps) data connectivity to embedded devices on the T-Mobile network for $20/month. As with cell phones, the LE910-NA1 will also operate on AT&T's network, though Telit did not mention any such certification in its announcement. LTE-M has a 1.4 MHz bandwidth with peak data rate of 1 Mbps.

On June 27, Telit announced the LE940A9, an addition to its family of automotive-grade modules. The LE940A9 adds 450 Mbps download and 50 Mbps upload speeds with "extremely low latency and advanced security," which is needed for vehicle-to-vehicle (V2V) communications. The company doesn't define "extremely low" in the release nor on it's website. You must personally request a data sheet for this module.

Because those developing connected devices won't wait for 5G, Verizon and AT&T announced the launching of their Long-term Evolution for Machines (LTE-M) networks. LTE-M—part of 3GPP Release 13—adds low speed, low power connectivity to devices.

Now that I have an LTE-capable phone (two if you count my iPhone 6 work phone), do I really need LTE? Not really, for I keep LTE disabled (Figure 4). After all, 4G without LTE is fast enough for watching any streaming video, so why shorten battery life.

The one with the new mrt

The new mrt services is finally here.
Do u know that i was the advisor, for this project?

++the one who is now 36

and i havent settled down, or
maybe, just maybe i am already settled, with this kind of life.
yaknow, this 'no partner, no kid/s, no big commitment''s life,
and i can migrate to whichever place, whenever i want to (except of course i dont have the money & maybe the energy).
last weekend when i discussed the idea of saving, with abcxyz, i told him i dont have the asb saving.
if i die tomorrow, i think my insurance can cover my debt (creditcards), (nih i think), and i dont have any children, so dont have to save money for their education watsoeva.
giler narrow minded kan.

but that's that.
that's when i am so content with my life that i dont think i am being rational.
what if i dont die, but i met with an accident and paralyzed.
wah takotnyaaaaaaaaaaaaaaaaa

ok entry ini ter stop disini kerana saya sudah jiwa kacau pula nya.

currently listening to:stay the night
currently feeling:scared
i wanna be:richhhhhhhhh

++the one with new hair

i know how lameeeeeeee (and bbnu) this post is.
but i've colored the crown recently.
and i love the color and for the first time in my mid 30s, i felt like keeping it long and i wanna do it again, with many shades.

well picture was taken right after the hairdresser hairblowed my hair.
now that it wasnt, ia mcm mop lantai yg gersang dan kering. ahahahahhahah

currently listening to:konayuki
currently feeling:kenyanggggg
i wanna be:supermodellllll
