2. 4G FOR THE U.S. GOVERNMENT —
TRENDS & CHALLENGES
Mobility is a primary enabler of workforce efficiency. Mobile broadband access reduces the time to perform regular business
functions through a more rapid response to situations that require collaboration regardless of team members’ locations. This
gives transparent access to critical data and applications anywhere, anytime, on any device.
Until 2010, most second and third generation cellular networks were based on air interface standards such as Global Systems
for Mobile (GSM), Universal Mobile Telecommunications System (UMTS), and Code Division Multiple Access (CDMA).
While these standards support both voice and data, none use end-to-end Internet Protocol (IP) that most Federal Government
enterprises utilize on a daily basis. Therefore, federally approved protection systems to secure data in flight and at rest
on a Federal Government enterprise do not secure the federal data over a commercial cellular network. In 2010, the 3GPP1
specified Long Term Evolution (LTE) as the global standard for 4G networks. As a result, commercial service providers are
investing in LTE networks to handle the rapidly increasing demand for mobile broadband voice, data and video.
The mobile government worker needs to use their mobile device across multiple environments with different security levels
from the home to a government enterprise to a secure government enclave. Therefore, the Federal Government has drivers
that exceed those of commercial mobile subscribers.

BENEFITS OF 4G MOBILE SOLUTIONS
4G mobile services have the potential to dramatically change the way Federal Government accesses and provides unified
communications, resulting in improvements in Network Performance, Cost Savings, and Services Management.
Network Performance: 4G LTE technology extends unified communications to the mobile workforce, improves user
experience, and enhances situational awareness for mission-critical services. This technology offers major performance gains
over its predecessor technologies, including delivering broadband to the mobile user at a much lower cost per bit. Gains are
attributed to:
» Orthogonal Frequency Division Multiplexing (OFDM) – modulation techniques for increased spectral efficiency.
» Multiple Input Multiple Output (MIMO) – antenna technology for increased link capacity for better user experience.
» Flat IP architecture – end-to-end IP which reduces latency and enables real time interactions.

3. Improvements in 4G over 3G technologies result in a 10-fold increase in throughput, 4-fold increase in spectral efficiency,
and a 6-fold gain in reduced latency.
Cost Savings: LTE delivers a single global standard, achieving higher economies of scale than 3G technologies. The
commercial wireless market is experiencing global investment in the LTE technology and user devices. For example, Global
Mobile Suppliers Association (GSA)2 reports that 327 operators in 99 countries have committed to commercial LTE network
deployments. There are 347 LTE devices from 63 manufacturers and 72 commercial LTE networks in 37 countries. Fueling
this dramatic subscriber growth is the explosion of mobile broadband data. Cisco3 projects that global mobile data traffic
is expected to grow at a compound annual rate of 91% over the next five years. To handle these trends in data growth,
subscriber increases, and mobile devices, 4G offers superior quality of service. The U.S. Government’s adoption of LTE
should leverage commercial wireless infrastructure and user devices, and potentially reduce service costs.
Services Management: A significant advantage of migrating to 4G mobile services is the potential to offer a secure end-user
experience.
Fueling this dramatic subscriber growth is the explosion of mobile broadband data. Cisco1 projects that global mobile
data traffic is expected to grow at a compound annual rate of 91% over the next 5 years. To handle these trends in data
growth, subscriber increases and mobile devices, 4G offers superior quality of service. The USG’s adoption of LTE should
leverage commercial wireless infrastructure and user devices, and therefore
potentially reduce service costs, increase the diversity of devices, and extend
the availability of mobile broadband.
Mobile services management can be achieved through an LGS integrated
platform that manages dual-homing user devices across multiple networks Same device - multiple networks & security requirements
from the home to the government enterprise to secure enclaves. By providing
centralized control for device management, real-time policy-based identity
access, and real-time visibility across the network elements and application
layers, the Federal Government 4G workers have ubiquitous, secure mobile
services.
A significant challenge in realizing the benefits of 4G is to ensure the security and integrity of highly sensitive and/or
classified data. Examples include authentication of user and network, centralized identity and device management, policy
enforcement, and the protection of data inside and outside the U.S. Government. Additionally, the Department of Defense
(DoD) has unique challenges such as the secure access of information at multiple classification levels under multiple
authorities (DoD, DHS) and the Certification & Accreditation process.
4G Mobile Solutions adhere to inherent, commercial LTE security mechanisms but also incorporate these security criteria:
» Ensure security & privacy
» Data integrity, separation, protection & management
» Policy-based service management
» Real-time traffic and threat analysis.

4. SUMMARY
4G Mobile Solutions will be a primary enabler to enhance the Federal Government’s workforce efficiency. Transparent
and secure access to high speed, broadband information reduces the time required to perform regular business regardless
of team members’ locations - anywhere, at any time, on any device. A key component of the recently announced Federal
Government’s Digital Strategy is the ability to deliver and receive digital content in any format in a safe and secure manner.
LGS 4G Mobility Solutions provide the foundation to transform the Federal Government’s IT infrastructure and achieve the
Digital Strategy goals.
