2. Introduction.
Project Fi is Google's program to provide fast
and easy cellular service directly to phones.
It actively switches between the networks
without any user intervention.
Project Fi also leans on Wi-Fi, and lets you
both call and text when connected to a Wi-Fi
network.
5. How it works
Project Fi intelligentlyconnects youto the
best network at your location whether it’s
Wi-Fi ,4G LTE or3Gnetworks.
It dynamicallydetermines based on several
factors which network is better.
6. Network switching to wifi
Project Fi automatically switches its users from a
cellular tower to a free Wi-Fi system with a signal
strong enough to stream video andmusic, another
effort to savepeople money.
This could mean a smartphone willshift to aWi-Fi
network downloading at 10 megabits, even if a
cellular network is available at 30 megabits.
7. Factors in Determining network choice
•Signal strength
•Signal to noiseratio
•Bandwidth availability
•Channelavailability
9. MultiIMSI Sim Card
The International Mobile Subscriber Identity is used to identify
the user of a cellular network and is a unique identification
associated with all cellular networks. It is stored as a 64 bit field
and is sent by the phone to the network. It is also used for
acquiring other details of the mobile in the home location
register (HLR) or as locally copied in the visitor location register.
10. MultiIMSI Sim Card
Usually the sim card has onlyone IMSIno butin case of
Project Fi sim card there can be10 differentIMSI nos.
Thus it can connect to potentially 10 differentnetworks at a
time.
12. Seamless Handoff
As Project Fi connects to 3 different kind
of networks
1. 3G
2. 4G
3. Wi-Fi
So it requires a lot of handoffs switching
between these.
13. GoogleAS MVNO
MVNO is MOBILE VIRTUAL NETWORK
OPERATOR.
MVNO resells the services from
traditional operators.
Google acts as MVNO for switching
between different cellular networks .
15. Googlecore voice network
Rather than directly connectingto the service providerProject
Fi maintains an active connectionwith Googlecore voice
network.
It’s the dutyof core voice network to successfully perform
handoffproperly.
16. Modified Radio Chip
Project FiUses Qualcomm Third GenerationLTE Chipsets that support LTE
Advanced with LTE Carrier Aggregation with HSPA+as a core. The MDM9625
chipsets are Implementedin a 28nm manufacturingprocess, the chipsets will
featuresignificantimprovements in performance and power consumptionfrom
previous generations and provide support for multiplemobile broadband
technologiesto deliver a best-in-classmobilebroadband experience for
smartphones, tablets, ultra-portable notebooks, portable hotspots, dongles and
CPEs (Customer PremisesEquipment).
18. Availability.
Project Fi is currently available inUnited Sates Of America
onlyon a invite onlybasis.
Googleplans to extend itto other countries too.
19. Subscription Plans.
Project Fi is having a base fee of
registration of $20 onlyand the costs only
$10 perGB of data used.
The international roaming in
120+countries and with noextra charges
in this network.
Cashback for unuseddata
23. Conclusion
Project Fi is certainly the first in awave of products to
disrupt the traditional operator business models, and google
willbe watching closely over the years to come to see how
to change andimprove it over time.
