Why MMW Wireless?

• Problem with many frequencies between 2GHz and 40GHz– Traditional PTP use channel widths up to 56 MHz / 360

Mbps. – Gigabit speeds would need 156 MHz of spectrum. This

amount is simply not available in the traditional Licensed Microwave Bands.

– The Licensed Microwave Bands are now so full in urban areas that acquiring even a 7 MHz channel are proving challenging

• Moreover, in order to deliver higher data speeds, more radio frequency bandwidth is needed.

• MMW bands at 60, 70, 80 and 90 GHz unlock 19 GHz of spectrum

E-band or V-band ?

60GHz and 80GHz links• Easy to install• Highly immune to interference• Not effected by fog, snow or sand storms • Offer up to 99.999% availability• Provide highly secure wireless connections

60GHz links• Short distance (up to 1,5 km)• Oxygen absorption

• Link-protection effects• Frequency reuse

• Small & Narrow beam antenna• Collocated installations

80GHz links

• Longer distance (up to 3-5 km)• Bigger antennas (35-90 cm) & heavy

devices

Typical using MMW links

Typical usage• Extending LANs between campus

buildings• Connecting enterprise sites into

metro fiber backbones• Creating virtual fiber backbones

and meshes • Alternative when costs or delay

make fiber unattractive

Myths & True about MMW- what to check before selection (1.)

– “Link can work up to 5-7 km”– Effective link distance and

subsequent availability is affected by Free Space Loss (FSL), Oxygen Absorption & Loss Caused by Rain

– Use simple calculator for predictions availability for given ranges

• Typical for Moscow 1 km (V-band) / 3,1 km (E-band) for 99.99%

– Talk with current users and get info about reality

1. DISTANCE

Myths & True about MMW- what to check before selection (2.)

– Not the same capacity in documents

• “compare apples with apples” • TDD divided by 2 is not the same

as FDD

– FDD - full data capacity always in each direction

– FDD offers significantly lower latency (transmit and receive functions simultaneously)

– TDD means higher packet jitter – performance limited (packets retransmission)

– TDD more complicated to transfer sync data

2. TDD or FDD

Myths & True about MMW- what to check before selection (3.)

– Check Specs x real parameters – Focus on receiver sensitivity /

Tx power – real distance should be shorter

– What modulation is mainly used for selected distance – real capacity should be less

– How error correction is used – performance should be less

– Temperature stability – what if temperature is changing below zero degrees – link can be disconnected

3. Link stability

Where Could 60GHz Links be Used?

• New links in congested areas• Network concentration to support higher

capacity of data traffic• To replace existing links with higher

capacity systems allowing greater data throughput

• Ad-hoc installations to support temporary events or network maintenance

Business case: "Efficient Backhauling"

Customer: Operator using legacy 38 GHz links

Sub10 Offer: 1 Gbps Full-Duplex via the Sub10 V1000

Network Concept: Replacement legacy mw 38 GHz to provide higher capacity in network and save licensing costs

Advantage: Low profile installation at street level (can be for Metro & Small Cells for mobile operators) . No delay of the network roll-out due to time consuming frequency applications. Very high density of links per km² without interference

Replace Licensed MW by MMW

Business case: "Wireless Fiber"

Customer: Service Provider (SP) / Wholesale provider

Sub10 Offer: 1 Gbps Full-Duplex via the Sub10 V1000

Network Concept: SP rents fiber from incumbent / fiber provider in the city. B2B and B2G customers will get fiber access (last mile) distributed via the Sub10 wireless links

Advantage: SP customers get fiber capacities at much lower cost and much shorter installation time compared to other operators (real example - 2

weeks after contract sign-off)

Advantage SP: The link can be de-installed and re-used in case a SP customer switches to another operator (which is not possible with Fiber). Moreover SP achieves a

much quicker ROI compared to fiber.

WIN-WIN for City Provider

Building to Building Fiber in Air (1.)

Building to Building connection with up to 1 GB\s Fixed or temporary solution to cross the streets, railroads, etc. Quick & Easy installation & integration - Connectivity within hours

Building to Building Fiber in Air (2.)

Traditional microwave license fee is too expensive Limited size of installed antenna & device High capacity required

Business Case: "Replacement of Leased Lines / Leased Fiber"

Customer: Hospital, University, Government

Sub10 Offer: Sub10 Liberator Portfolio

Network Concept: Replacement of leased lines and additional connection of new buildings

Advantage 1: Customer is is saving a five digit amount of money every year due to thereplacement of high capacity leased lines. All Liberator systems & the installation costs are already paying off after 8 months. The connection of new buildings with fiber would have caused high installation costs & a waiting time of 10 months. The Liberator network was installed within days.

“Fiber” Infrastructure in Campus without Cables

Backhauls optimization in mesh network (1.)

Typical requirement- Small area- Good coverage fro fixed & mobile users- Limited cable / fiber infrastructure- Wireless backhauls to mesh AP

Business Case: ”Increasing capacity in mesh network"

Customer: Mesh network operator / Mining company

Sub10 Offer: Sub10 Liberator Portfolio

Network Concept: Replacement of 5GHz backhauls in mesh network

Advantage 1: Using Liberator working in millimetre waves provides higher capacity and allows the mesh network to operate without interfering in 2.4 or 5 GHz band, which the mesh network use for communication with mobile users / terminals or between nodes. The results is there is less noise across the network and mesh network can operate more efficiently with higher network capacity.

Backhauls optimization in mesh network (2.)

Business Case: ”Temporary Connectivity for tine limited event / Time critical & emergency maintenance"

Customer: Operator / End customer with critical application, Temporary office

Sub10 Offer: Sub10 Liberator Portfolio

Network Concept: Extension of fiber network in areas with missing infrastructure / Temporary replacement for part of network under maintenance

Advantage 1: Using advantage from easy & quick installation, low power consumption and small factor of Liberator provides high capacity solution for temporary installations. Alternative method of powering can be considered for such deployment.
