Why LTE?

Customer Perspective Cambium Perspective

• Small WISP (<2,000 subscribers)– NLOS performance, need for better range

and coverage than other available solutions

• Medium WISP (2,000-10,000 subscribers)– Licensed spectrum to add capacity and

provide premium service– Investment protection– Inexpensive CPE options

• Large WISP (> 10,000 subscribers)– Investors demand industry standard LTE– Attractive Air Interface attributes– Inexpensive CPE

• Adopt industry standard and innovate rather than reinvent

• Lower Cost SM: LTE chipsets are inexpensive relative to FPGA & DSP

• LTE air interface features– OFDMA in downlink– Improved receive sensitivity due to coding

gains– Carrier aggregation and LAA– Frequency reuse 1 – for licensed bands– Inter cell interference coordination– Hybrid ARQ with soft combining

Why Not Use Existing LTE solutions?

– Too complex (EPC, SIM cards)

– Too costly

– Not Fixed Service Provider-friendly

– Products that exist are immature or “beta quality”

Cambium Networks - Differentiating on a Standard

• Remove cost and complexity typically associated with LTE

• Exploit LTE Air Interface Features

• High power radio to take advantage of higher regulatory limits in 2.5GHz and 3.5 GHz

• Leverage our expertise in robust outdoor CPE design

• Retain PMP 450 networking, QoS, security and management features

• Building on our 450 to LTE comparison, we close the gap between the existing solutions and the Cambium LTE solution.

• 450 still outperforms LTE in many ways, but Cambium’s LTE addresses deficiencies in alternative LTE solutions.

8x8 Radio

PMP450 has baseband and radio together

LTE will have 8x8 Baseband Unit (BBU) and Remote Radio Heads (RRH)

The BBU can drive 4 2x2 radios to provide 360⁰ coverage …

… Or one 8x8 radio for a singleSector with MU-MIMO support

Deployment

CPRI (Fiber)

• Start with one RRH, add more as you grow, all powered by same BBU

• RRH band spins without changing BBU hardware

• Future proof for LAA, just add 5GHz RRU to existing BBU

• No tower climb needed to access BBU –easier diagnostics, lower operational expense
