Apple and iPhone 6 gently raise the LTE bar

iPhone6_34FR_SpGry_iPhone6plus_34FL_SpGry_Homescreen_HEROAs you probably have noticed Apple, the company famous for making computers, among other things, did something remarkable yesterday. Yes, it killed off the ‘Classic’ iPod. You know the one with the click wheel and the 50 trillion songs on your pocket slogan. I know, I can hardly believe it either. This is a great shame of course, especially as I was thinking of upgrading my 2005 model as just last week my iTunes library exceeded its 60GB capacity for the first time meaning I can’t just hook it up and sync. Ah, cruel world.

In the context of this blog though, I’m misdirecting you (in case you hadn’t noticed), as Apple also released three new devices in the shape of two new iPhones and a Watch, its first ‘wearable’. The latter, in all likelihood, marks the official start of the ‘IoT’, as previously ‘dumb’ devices become smart and connected. Yes, others have got their first, but no tech party can really begin till Apple arrives. (Then again, some people hate it).

In terms of LTE though, the new iPhones raise the bar, albeit relatively modestly. The phones now offer LTE support on 20 different bands, though not at once. As with the 5c/s there are three skews, with multiple variations for Europe, Asia and the US. TD-LTE support has also been slightly expanded with the addition of Band 41 – 2.5GHz.


Bringing LTE Indoors

As LTE networks continue to be deployed, it is becoming evident that matching the existing 3G coverage quality is going to be a challenge. This is reminiscent of the early days of 3G, when it took many years to get coverage matching underlying GSM. The higher carrier frequency (2.1GHz) and partial initial overlays left deep indoor coverage with “cold spots.”  This resulted in unreliable calls and increased battery consumption, which led many users to disable 3G out of frustration.  Over time, operators invested in more infill Broadband Telephony Services (BTS), wider use of In-building Systems (IBS) and repeaters, but indoor coverage was only really resolved when 3G on 850/900 MHz was deployed as a coverage “safety net.”
