Video Streaming

Webpage Browsing

• The web browsing & video streaming will be the main components of the mass mobile

broadband traffic

• The development of mobile broadband network will witness the same trends and

challenges that has appeared in fixed broadband network development

• The construction of mobile broadband network can refer to fixed broadband network

• Metro aggregation network is FMC ready, but not E2E FMC available

• The separation of IP RAN service stream by MPLS-TP & IP/MPLS networks breaks

E2E service features such as E2E protection & configuration

• The existing IP RAN equipment doesn’t fulfill strong IP/MPLS features as router does

• UPE routers are usually too big & expansive in metro access

E1 LL cost depends on distance & bandwidth

E1 LL is more popular in west Europe and North

America because of regulation and legislation.Dilemma of mobile broadband backhaul

E1 LL fareRegion

Leased Line Cost

Data service consume more bandwidth but bring less revenue.

Traditional TDM based technology can not support 3G/LTE.

The situation is even worse in case of renting E1 LL from 3rd party.

Migrate to all-IP is the long term strategy.

Mobile Operator’s Challenge for Backhaul Bandwidth


Mobile operator rent mobile backhaul network infrastructure (such as optical fiber, microwave, site pole/room, routers, transmission devices, etc) is very popular in Europe and North America:

1. USA, Sprint (Pure Mobile) and AT&T (Fixed + Mobile) rent backhaul from comcast (TV Operator)

2. UK, O2 rent backhaul from BT

3. Germany, T-Mobile rent backhaul from T-Home

4. Spain, Vodafone rent backhaul from Tele2

……

BUT, we still need to think about a lot

It’s Popular to Be the Pipe Operators


All the media in different network part,

need the universal pwe3 pipes go through

whole network, universal O&M

Integrate all the access method

(fiber, xDSL, PON, etc) into

same device.

Larger coverage, make use

of any available transport

media.

Without reasonable price and good

service, mobile operator will choose to self

build backhaul.
