MiFi

MiFi is a line of compact wireless routers produced by Novatel Wireless that act as mobile Wi-Fi hotspots. MiFi stands for 'My Wi-Fi'. The MiFi can be connected to a mobile phone (cellular) carrier and provide internet access for up to 5 devices. The MiFi works at a distance up to 10 m (30 ft) and will provide internet or network access to any WiFi enabled peripheral device.
The first MiFi device was introduced in the U.S. in May 2009 by Novatel Wireless,^[1] and Novatel owns a registered trademark on the "MiFi" brand name in the U.S.^[2] The Novatel MiFi is also marketed as such in the Netherlands, Egypt, Spain, Portugal, Germany, Poland, Romania, Hungary, Slovenia, Qatar, Kuwait, Bahrain, New Zealand, Singapore, Thailand, Japan, South Africa, Puerto Rico, Canada, and Mexico.^[3][4][5][6] However, in the United Kingdom, mobile operator 3 owns the "MiFi" trademark and markets a similar device from Huawei under the name.

MiFi (and MiFi-like) devices

Novatel MiFi 2200

• Limited to 5 Wi-Fi clients such as laptops, cameras, gaming devices and multimedia players; with the exception of manually editing the devices config file to allow more clients.^[8]
• May be connected to a computer via a MicroUSB connection, though doing so disables the Wi-Fi networking, converting the device into a traditional single-client modem. (However, CNET has introduced a tweak to charge the device over USB while maintaining its functionality.)
• Includes GPS unit, which is usable on some networks (Virgin) and not on others (Verizon).
• Uses 3G data network (CDMA 1xEVDO RevA).

Novatel MiFi 23xx series

Same functionality as 2200, plus:

• Accepts SD card for in-device shared media storage.^[9]
• Uses 3G data network (MiFi 2352: HSUPA/HSDPA 900/1900/2100 MHz, MiFi 2372: HSUPA/HSDPA 850/1900/2100 MHz; both support GPRS/EDGE 850/900/1800/1900 MHz).

• MiFi DLNA Server: start, stop and configure the MiFi DLNA server

4G MiFi devices

MiFi 4510L from Novatel Wireless for Verizon Wireless

MiFi 4082 from Novatel Wireless for Sprint Nextel

The Las Vegas Consumer Electronics Show 2011 saw the introduction of two new 4G capable MiFi devices from Novatel:

• Verizon Wireless featured the 4510L model, which will connect to Verizon's new LTE 4G network, expected to support 5–12 Mbps download and 2–5 Mbit/s upload.^[10]
• Sprint featured the MiFi 4082, a WiMAX version.^[11]

Both devices maintain backward compatibility with existing 3G networks. Other features include:^[12]

• MiFiOS with widget support
• MicroSD card slot
• GPS receiver
• 4 hour battery life
• Front panel status display using E Ink technology. The front panel display shows battery, signal strength and number of connected devices. The difficulty of viewing such information was seen as a major shortcoming of earlier MiFi devices.^[11]

Non-Novatel devices

• Huawei E5830 (Series), E585, E586 with HSPA+^[13] and Chinese market E5805 using CDMA2000 and ET536 using TD-SCDMA.

Femtocells and small cells reduce total network energy consumption

Climate change is a major concern worldwide today. Perhaps surprisingly, an award winning research study determined that the adoption of femtocells and small cells could reduce energy consumption by up to 70% in urban areas. With mobile networks needing to deliver more and faster data, the energy efficiency of doing so using small cells makes a compelling case.

Researchers from Alcatel-Lucent's Bell Labs were tasked to investigate the implications of mobile broadband on environmental sustainability. They looked at a variety of aspects, including replacing air travel with video conferencing and telecommuting from home. Although the report was published in 2009, it still makes a valid case for the energy efficiency of a small cell approach.

The telecom industry consumes a small but significant proportion of energy

Telecommunications networks do consume a small but significant percentage of global energy. A typical example given was for Telecom Italia using 1% of all Italian electricity, covering both fixed and mobile services. KPN in the Netherlands is quoted elsewhere also consuming 1%. Many operators are taking action to deal with this, such as consolidating into fewer data centres and using more efficient technology. France Telecom has set itself the goal of reducing power consumption by 20% by 2020.

Macrocells need a lot of power

The most interesting aspect for me was the comparison of power consumption between large macrocells and small cells. The report quoted a figure from 2007 of 2.7kW per macrocell site which compares with as little as 5W for the latest femtocells. Hundreds of femtocells can be deployed for the same energy footprint. HIgher capacity small cells may use several hundred watts, and still be more energy efficient if deployed in areas of high utilisation.
This equates to a substantial energy bill for the network operator too. In countries where electricity is hard to connect up to, diesel generators may have to be installed on site. The cost of these, including the cost of delivering the fuel to each site, can make energy costs even more significant. For example, in Africa, energy can rise to as much as 75% of total network operating costs.

More energy efficient macrocells

Measures have been taken to deal with this issue of course. The latest basestation products are much more energy efficient that their predecessors. Vendors have added features which reduce power, such as switching off additional carrier capacity overnight, more efficient power supplies and RF power amplifiers. For more remote sites, standalone energy management techniques have been introduced from the likes of Power Oasis.

But small cells still make a more significant difference

The study found that while macrocells would be a more energy efficient solution for voice only networks, total energy savings of up to 70% could be achieved through use of femtocells and small cells. As the industry moves further towards high speed data centric traffic, the case becomes even more compelling.

Relatively small takeup can still make a difference

An operator with 40% market share, 20% of customers with femtocells can still satisfy 80% of total demand from customers. The study found that network operators with lower market share would benefit more through some form of network sharing agreement. The larger proportion of accessible femtocells would deliver higher performance and greater utilization where more customers can access these devices.

Summary

Great strides have been made in reducing the energy footprint of mobile networks in recent years. The continuing growing demand for faster and higher capacity mobile data provides a compelling case for small cell deployment. The reduced impact on climate change combined with reduced energy bills is enticing. This research paper makes a strong case for small cells , particularly to satisfy the thirst for mobile data.

5G Mobile Phone Concept

Today 3G mobile systems are on the ground providing IP connectivity for real-time and non-real-time services. On the other side, there are many wireless technologies that have proven to be important, with the most important ones being 802.11 Wireless Local Area Networks (WLAN) and 802.16 Wireless Metropolitan Area Networks (WMAN), as well as ad-hoc Wireless Personal Area Network (WPAN) and wireless networks for digital TV and radio broadcast. Then, the concepts of 4G is already much discussed and it is almost certain that 4G will include several standards under a common umbrella, similarly to 3G, but with IEEE 802.xx wireless mobile networks included from the beginning. The main contribution of this paper is definition of 5G (Fifth Generation) mobile network concept, which is seen as user-centric concept instead of operator-centric as in 3G or service-centric concept as seen for 4G. In the proposed concept the mobile user is on the top of all. The 5G terminals will have software defined radios and modulation scheme as well as new error-control schemes can be downloaded from the Internet on the run. The development is seen towards the user terminals as a focus of the 5G mobile networks. The terminals will have access to different wireless technologies at the same time and the terminal should be able to combine different flows from different technologies. Each network will be responsible for handling user-mobility, while the terminal will make the final choice among different wireless/mobile access network providers for a given service.

Voice over LTE via Generic Access (VoLGA) A Whitepaper

Voice over LTE via Generic Access (VoLGA) PDF

The roots of 'Voice over LTE via GAN' (VoLGA) are the 3GPP Generic Access Network

(GAN) specifications which add Wi-Fi as an access technology to 3GPP based networks such

as GSM and UMTS. GAN requires dual mode mobile devices which have both a

GSM/UMTS radio interface and a Wi-Fi radio interface. Such mobile devices are available

today from a number of manufacturers including Samsung, Nokia, Sagem, LG, HTC3,

Motorola4, Sony-Ericsson and RIM (Blackberry)5. When these dual-mode devices detect the

availability of a suitable Wi-Fi network, e.g. at home or a public hotspot, they connect to the

Wi-Fi access point and register with the GSM/UMTS core network over the Wi-Fi link and

the Internet. A GAN gateway securely connects a subscriber to the infrastructure of a network

operator and voice calls and other circuit switched services such as SMS are then securely

transported between the mobile device and the Gateway over the intermediate Wi-Fi link and

Internet access network.

VoLGA re-uses this principle by replacing the Wi-Fi access with LTE.

Commercial Mobile Alert System (CMAS) in Release-9

                                                                
The following is an extract from 3G Americas white paper, "3GPP Mobile Broadband Innovation Path to 4G: Release 9, Release 10 and Beyond: HSPA+, SAE/LTE and LTE-Advanced,":

In response to the Warning, Alert, and Response Network (WARN) Act passed by Congress in 2006, the Federal Communications Commission (FCC) established the Commercial Mobile Alert Service (CMAS) to allow wireless service providers who choose to participate, to send emergency alerts as text messages to their users who have CMAS capable handsets.

                                                   
The FCC established a Commercial Mobile Service Alert Advisory Committee (CMSAAC) for the development of a set of recommendations for the support of CMAS. The CMSAAC recommendations were included as the CMAS Architecture and Requirements document in the FCC Notice of Proposed Rule Making (NPRM) which was issued in December 2007. In 2008, the FCC issued three separate Report and Order documents detailing rules (47 Code of Federal Regulations [CFR] Part 10) for CMAS. The FCC CMAS First Report and Order specifies the rules and architecture for CMAS. The FCC CMAS Second Report and Order establishes CMAS testing requirements and describes the optional capability for Noncommercial Educational (NCE) and public broadcast television stations distribute geo-targeted CMAS alerts. The FCC CMAS Third Report and Order defined the CMAS timeline, subscriber notification requirements for CMSPs, procedures for CMSP participation elections and the rules for subscriber opt-out. The FCC also issued a CMAS Reconsideration and Erratum document.

The CMAS network will allow the Federal Emergency Management Agency (FEMA), to accept and aggregate alerts from the President of the United States, the National Weather Service (NWS), and state and local emergency operations centers, and then send the alerts over a secure interface to participating commercial mobile service providers (CMSPs). These participating CMSPs will then distribute the alerts to their users. between the issuance of the second and third Report & Order documents.

As defined in the FCC CMAS Third Report and Order, CMSPs that voluntarily choose to participate in CMAS must begin an 18 month period of development, testing and deployment of the CMAS no later than 10 months from the date that the Government Interface Design specifications available. On December 7, 2009, the CMAS timeline of the FCC CMAS Third Report and Order was initiated with the announcement by FEMA and the FCC that the Joint ATIS/TIA CMAS Federal Alert GW to CMSP GW Interface Specification (J-STD-101) has been adopted as the Government Interface Design specification referenced in the FCC CMAS Third Report and Order.

Participating CMSPs must be able to target alerts to individual counties and ensure that alerts reach customers roaming outside a provider’s service area. Participating CMSPs must also transmit alerts with a dedicated vibration cadence and audio attention signal. Emergency alerts will not interrupt calls in progress. CMAS supports only English text-based alert messages with a maximum displayable message size of 90 English characters.

For purposes of CMAS, emergency alerts will be classified in one of three categories:

1. Presidential Alerts. Any alert message issued by the President for local, regional, or national emergencies and are the highest priority CMAS alert

2. Imminent Threat Alerts. Notification of emergency conditions, such as hurricanes or tornadoes, where there is an imminent threat to life or property and some immediate responsive action should be taken

3. Child Abduction Emergency/AMBER Alerts. Alerts related to missing or endangered children due to an abduction or runaway situation

The subscribers of participating CMSPs may opt out of receiving Imminent Threat and Child Abduction/AMBER alerts, but cannot opt out from Presidential Alerts.

The following figure shows the CMAS Reference Architecture as defined in the FCC CMAS First Report and Order:


Reference Point C is the secure interface between the Federal Alert GW and the Commercial Mobile Service Provider (CMSP) GW. The Reference Point C interface supports delivery of new, updated or canceled wireless alert messages, and supports periodic testing of the interface. This interface is defined in the J-STD-101, the Joint ATIS/TIA CMAS Federal Alert GW to CMSP GW Interface Specification.

Federal Government entity (i.e. FEMA) responsible for the administration of the Federal Alert GW. FEMA will perform the function of aggregating all state, local, and federal alerts and will provide one logical interface to each CMSP who elects to support CMAS alerts.
For GSM and UMTS systems, wireless alert messages that are received by CMSP GWs will be transmitted to targeted coverage areas using GSM-UMTS Cell Broadcast Service (CBS). The CMAS functionality does not require modifications to the 3GPP-defined Cell Broadcast Service.
The ATIS WTSC-G3GSN Subcommittee is developing the CMAS via GSM-UMTS Cell Broadcast Service Specification. The purpose of this standard is to describe the use of the GSM-UMTS Cell Broadcast Service for the broadcast of CMAS messages. The standard includes the mapping of CMAS application level messages to the Cell Broadcast Service message structure.
The ATIS WTSC-G3GSN Subcommittee is developing the Cell Broadcast Entity (CBE) to Cell Broadcast Center (CBC) Interface Specification. The purpose of this standard is to define a standard XML based interface to the Cell Broadcast Center (CBC). The CMSP Alert GW will utilize this interface to provide the CMAS Alert message information to the CBC for broadcast via CBS.
The ATIS WTSC-G3GSN Subcommittee has developed the Implementation Guidelines and Best Practices for GSM/UMTS Cell Broadcast Service Specification and this specification was approved in October 2009. The purpose of this specification is to describe implementation guidelines and best practices related to GSM/UMTS Cell Broadcast Service regardless of the application using CBS. This specification is not intended to describe an end-to-end Cell Broadcast architecture, but includes clarifications to the existing 3GPP CBS standards as well as “best practices” for implementation of the 3GPP standards. CMAS is an example of an application that uses CBS.

J-STD-100, Joint ATIS/TIA CMAS Mobile Device Behavior Specification, defines the common set of requirements for GSM, UMTS, and CDMA based mobile devices behavior whenever a CMAS alert message is received and processed. A common set of requirements will allow for a consistent user experience regardless of the associated wireless technology of the mobile device. Additionally, this common set of requirements will allow the various local, state, and Federal level government agencies to develop subscriber CMAS educational information that is independent of the wireless technology.

CMAS VIA LTE/EPS

In order to comply with FCC requirements for CMAS, CMSPs have a need for standards development to support CMAS over LTE/EPS as it relates to the network-user interface generally described as the “E-Interface” in the CMAS Reference Architecture. The intent of ATIS WTSC-G3GSN is to build upon LTE text broadcast capabilities currently being specified by 3GPP for the Public Warning System (PWS).
3GPP STANDARDS

3GPP TS 22.268. Public Warning System (PWS) Requirements, covers the core requirements for the PWS and covers additional subsystem requirements for the Earthquake and Tsunami Warning System (ETWS) and for CMAS. TS 22.268 specifies general requirements for the broadcast of Warning Notifications to broadcast to a Notification Area that is based on the geographical information as specified by the Warning Notification Provider. This specification also defines specific CMAS requirements based on the three Reports & Orders issued to date by the FCC.

3GPP TS 23.401. GPRS enhancements for E-UTRAN access, specifies the Warning System Architecture for 3GPP accesses and the reference point between the Cell Broadcast Center (CBC) and Mobility Management Entity (MME) for warning message delivery and control functions. This TS identifies the MME functions for warning message transfer (including selection of appropriate eNodeB), and provides Stage 2 information flows for warning message delivery and warning message cancel. The architecture and warning message delivery and control functions support CMAS.

3GPP TS 29.168. Cell Broadcast Center interfaces with the EPC – Stage 3, specifies the procedures and application protocol between the Cell Broadcast center and the MME for Warning Message Transmission, including the messages, information elements and procedures needed to support CMAS.

3GPP TS 36.300. E-UTRA and E-UTRAN – Overall description – Stage 2, specifies the signaling procedures for the transfer of warning messages from the MME to the eNodeB. The signaling procedures support CMAS operations.

3GPP TS 36.331. E-UTRA Radio Resource Control (RRC) – Protocol specification, specifies the radio resource control protocol for UE-to-E-UTRAN radio interface and describes CMAS notification and warning message transfer.

3GPP TS 36.413. E-UTRAN – S1 Application Protocol (S1AP), specifies the E-UTRAN radio network layer signaling protocol between the MME and eNodeB, and describes the warning message transfer needed for CMAS.
3GPP participants are working to complete these specifications and other UE procedures for supporting PWS and CMAS.
ATIS WTSC-G3GSN will develop a Standard for a CMAS via LTE Broadcast Capability Specification. This Standard will map the CMAS application level messages to the LTE warning message transfer protocol (i.e. for CMAS).
This ATIS WTSC-G3GSN effort has an anticipated completion date of December 31, 2010. This takes into account the time needed for completion of the ongoing 3GPP standards development on warning message broadcast for LTE.
ATIS WTSC G3GSN and TIA TR45.8 Subcommittees in conjunction with FEMA will also be jointly developing a testing certification specification for the Reference Point C interface between the Federal Alert GW and the CMSP GW based upon the requirements defined in J-STD-101. This specification has an anticipated completion date of December 31, 2010.

A Simulation Tool for Dimensioning and Performance Evaluation of the UMTS

A Simulation Tool for Dimensioning and Performance Evaluation of the UMTS pdf

The efficient support of multiple traffic classes with different quality
of service requirements (end-to-end delay, jitter, loss) poses an extraordinary
complexity in the design of third-generation mobile networks. This task becomes
especially critical for the access network, where radio and transmission
resources are usually scarce. In this paper we present a simulation model of the
ATM-based UMTS (Universal Mobile Telecommunications System) terrestrial
radio access network. The simulator aims to provide a test bed for conducting
further research studies on several topics of potential interest. In particular, we
intend to use the tool for dimensioning ATM links, for evaluating performance
under different mixes of traffic classes, and for investigating quality of service
mechanisms. This wide range of applications has led us to develop a very flexible
simulation model that captures many low level details. Some preliminary
results obtained with the simulator are presented in order to illustrate its capabilities.
