HSS

Implementation

HSS

is

implemented

using

a

master

(which

transmits

synchronization

pulses),

where

the

rest

of

the

co

‐

located

units

are

defined

as

clients.

These

client

radio

units

synchronize

their

transmission

to

the

pulses

received

by

the

master.

HSS

can

be

carried

out

between

all

co

‐

located

RADWIN

radio

products,

so

long

as

they

are

defined

as

a

base

station.

9.3.1

Radio

Frame

Pattern

The

synchronization

signal

is

transmitted

once

per

a

specific

time

period,

and

determines

when

the

co

‐

located

units

will

transmit

and

when

they

will

receive.

This

cycle

of

transmit

and

receive

is

called

the

Radio

Frame

Pattern

.

it

(HSM).

The
