BTS 2100 has high 10W + 10W output power

-
No matching product from other vendors, they have only 5W + 5W is available



Flexi
Lite

BTS has macro BTS feature set

-
Easy to plan and deploy micro or
pico

sites on existing macro network



Excellent MBB service capability due to macro BTS platform baseband


-

Same HSPA peak rates as with macro BTS e.g. HSDPA 84 Mbps and HSUPA 23 Mbps*




-
Traffic hot spots, coverage fix, indoor coverage, indoor
pico

or DAS, high traffic density

-
This is due to small size, light weight, tunable output power from 10W+ 10W to 250mW +
