According to latest reports Apple iPhone 6 will feature a Qualcomm MDM9625 LTE modem. Though the wireless modem is not the best from Qualcomm and not the latest, still it features some of the best technology options.

Here are some of the things you should expect from iPhone 6 modem.

Qualcomm MDM9625

Qualcomm MDM9625 features HSPA+ Release 10 and the next-generation of the LTE mobile broadband standard, LTE Advanced in the same chip. Apart from that MDM9625 is a category 4 LTE modem and supports Carrier Aggregation. This improves the downlink data rates up to 150 Mbps. Implemented in a 28nm manufacturing process, the chipsets will feature significant improvements in performance and power consumption from previous generations and provide support for multiple mobile broadband technologies to deliver a best-in-class mobile broadband experience.

Here are the key features of Qualcomm MDM9625 modem which will power Apple iPhone 6:

  • 28nm chipset design
  • Supports LTE Advanced (LTE Release 10)
  • Supports HSPA+ Release 10 (including 84 Mbps dual carrier HSDPA)
  • Backward compatible with other standards, including EV-DO Advanced, TD-SCDMA and GSM.
  • Downlink throughput of 150 Mbps when using LTE Advanced

Here is a video which shows what Qualcomm MDM9625 can capable of:

LTE MAC Layer – Medium Access Control

LTE User Plane and Control Plane LTE MAC Layer   Medium Access Control
This tutorial describes the specific details of the LTE MAC layer or the Medium Access Control protocol. MAC is a radio network protocol which resides both in the UE and in the E-UTRAN. Also, it should be noted that MAC protocol is available for both User plane and also for the control plane.

RRC (Radio Resource Control) protocol is in control of the configuration of MAC that means RRC decides how MAC will behave. For example RRC tells MAC to configure a specific PDU size. Continue reading

Hyper-dense small cells deployment for better coverage and throughput

UltraSON Small Cells deployments Hyper dense small cells deployment for better coverage and throughput
When the best data throughput of today becomes bad in couple of years and mobiles are used more as entertainment and file sharing purpose than voice call, we need new revolutions to achieve best data rate using existing technologies.

According to latest study by Qualcomm by 2017 two third of mobile traffic will be from video. There is also predictions that there will be 25 billion interconnected devices by 2020. So what is the solution to fix this data scarcity problem?

One of the solution is use many small cells which eventually works as WiFi hotspots. There may be unplanned deployments for both indoor and outdoor use.

Checkout this informative white paper from Qualcomm to understand the problem we are going to face soon and the use of hyper-dense small cells to solve data throughput issues.

Apple IOS 8 and VoLTE – Is iPhone 6 going to have Voice Over LTE?

ios 81 Apple IOS 8  and VoLTE   Is iPhone 6 going to have Voice Over LTE?

Apple announced iOS 8 early this week in a grand event. While there are many visual and other non-wireless features presented in WWDC 2014 there was definitely some parts which was for us those who work in mobile space.

Apple announced that they will support WiFi calling in IOS 8 and that is a welcome move. But as we all know WiFI calling is a old technology, infact T-Mobile is providing this from past couple of years. After the announcement that Apple will going to give software support on WiFi calling T-Mobile and Roger Wireless extended their hand and officially stated that they are going to support Apple.

  1. GSM has over 90% market share, and is available in over 219 countries and territories.
  2. “GSM” is a trademark owned by the GSM Association.
  3. In 1981 Groupe Spécial Mobile was created to develop a European standard for digital cellular voice telephony. European Conference of Postal and Telecommunications Administrations (CEPT) had taken this initiative.
  4. In 1987 Europe produced the very first agreed GSM Technical Specification in February. Phase I of the GSM specifications were published in 1990.
  5. In 1989, the Groupe Spécial Mobile committee was transferred from CEPT to the European Telecommunications Standards Institute (ETSI).
  6. Continue reading
