Introduction Introduction Backhaul: Once the “after thought” of the wireless infrastructure Explosive amounts of data back through the wireless
infrastructure in the last (5) years 4G and LTE are pushing the boundaries of the existing network Now considered an essential element of the network:
The New Wireless Cash Cow? Standard T1 copper network unable to meet the new topology
Wireless backhaul is essential to today’s network

Evolution of Wireless BackhaulEvolution of Wireless Backhaul Initial providers only focused on voice As network speed evolved (LTE),
data became the primary driver Large data streams brought greater
demands on wireless backhaul 20% of copper backhaul is over-
burdened; rising to 50% by 2015 Today’s copper T1 backhaul can
handle a maximum of 1.5 to 2 Mbps
Wireless backhaul needs to meet the ever growing network requirements of today

Wireless Market Evolution Wireless Market Evolution Consumer Needs Greater mobile flexibility through
voice, text, email and video Faster data speeds for mobile
applications
Service Provider Needs Lower infrastructure costs High speed radio systems Ethernet and microwave
backhaul compatibility VoIP
The wireless infrastructure is data centric

Mobile Data Replaces Fixed DataMobile Data Replaces Fixed Data Broadband subscribers to
reach 3.4 billion by 2014 80% of the users will be
mobile based Fixed broadband growth
expected to remain near static Service providers are being
driven by (2) distinct trends Increase in smart mobile devices Data centric applications
4G networks in North America will increase data traffic 26 fold from 2010 through 2015

Wireless Backhaul Market DriversWireless Backhaul Market DriversCell Site Growth Approximately 300,000 sites in the US Expected to grow to 430,000 by 2015 in the US
Smart Phone Impact Smart phones account for 15% of the market share today,
but they account for 78% of the data traffic In 2010 over 3 million tablets were connected to the network
generating five times as much data as smart phones
Migration towards LTE (Long Term Evolution – 4G) Speeds increasing from ~3Mbps to 20-100Mbps Bandwidth increasing from ~20MHz to 100MHz

Three Main Transport Methods Copper (T1s) Fiber Microwave
Copper/Fiber Hybrid Solution Copper – TDM great for voice, not so great for data Fiber – Ethernet great for data, allows transition to VOIP
Carrier Base Station Mobile Switching Office (provisioning, call routing, etc)
Access Network
Handset, PDA or Laptop
Public Switched Telephone Network

Wireless Backhaul Infrastructure TrendsWireless Backhaul Infrastructure Trends Fiber quickly replacing
copper to meet LTE bandwidth requirements
Point-to-point microwave backhauled to fiber to save cost
Ethernet over T1 driving savings, greater data flow and greater reliability

The Dark Side of BackhaulThe Dark Side of Backhaul Revenues may not keep pace with data
surges through the wireless network Cost to deliver a “byte” of data will exceed
generated revenue by early 2013 Top two service providers are laying fiber to
the majority of their edge midstream networks Lower tier suppliers may choose NOT to
upgrade the backhaul infrastructure Cost to enter may cause a “wait and see” approach Risk of increased rate of churn
Small regional/rural service providers may gain access to low interest loans and funding via government broadband initiative

Backhaul Technology ComparisonBackhaul Technology Comparison

Microwave Fiber lines
Capacity · Up to several Gbps · Unlimited
Regulation · Requires spectrum· Visual impact considerations
· Requires right of ways and infrastructures; renovation construction works after trenching
Distance influence on costs and deployment time
· Cost per link with some incremental cost with the distance· Fast deployment time
· Costs increase per feet/meter· Deployment time increases linearly with distance
Terrain· Suitable for any terrain· Requires line-of-sight between two link end-points
· Becomes costly when trenching in difficult terrain (mountains, deserts, swamps, rocky plains or jungles)· Accessibility - requires access for vehicles along the trenching path
Reuse options· Equipment can be disassembled and relocated somewhere else
· Fiber, in most cases, cannot be relocated· Copper ducts may be reused for fiber lines
Climate· Influenced by climate· Adaptive modulation and a proper link planning reduces climate effects
· Normally, not influenced, except for floods

ConclusionsConclusions Data has become the dominant mobile
transmission vehicle of backhaul topology Transition to LTE and VOIP
will only increase the burden on the backhaul network
Providers that securely manage data in their networks will be financially successful long term
The wireless backhaul network will be defined by: Speed $$$ (short and long term) Terrain Climate
